Kilroywashere: /* Enable telnet */

== How to enable Telnet/NFS/CIFS/SAMBA ==

This How to will help you enable telnet and get your NFS/CIFS/SMB shares to auto start when your Samsung starts up. Thanks to dynamic1969 for all his help, erdem_ua for SamyGo.py

This HOW TO is work in progress. I will be updating it as I update my scripts.

Fist of all you need to change rc.local to boot from the writable partition. You can archive this two ways:
#Manually Modifying the Firmware. (NEED TO ADD MY HOWTO)
#Automated Way - SamyGO Firmware Patcher (with modification).

I can confirm i have tested both methods and it worked on mine. ('''DO THIS AT YOUR OWN RISK!!!''')

===Manually Modify Firmware===
To modify the firmware manually please see the two guides bellow, currently the Linux guide is not yet complete.

*[[How to enable Telnet on samsung TV's]]
*[[How to Modify the Firmware using linux]] (NEED TO POST)

===Automated Firmware Update===
To use the SamyGO Firmware Patcher to modify your firmware you will benefit from having less chance of bricking your TV. You will also be able to take advantage of the VideoAR fix, and not need all the tools detailed in the Manual Enable Guide.

You will need to do the following:

Download the latest [http://download.samygo.tv/ SamyGO Firmware Patcher]

Download the latest firmware from [http://www.samsung.com/ Samsung] and extract it.
run SamyGo.py against the latest downloaded firmware. *note this needs to be a clean firmware not an already modified one.
example:
python ./SamyGO.py ./T-CHU7DEUC/

and select "Advanced mode" instead of Telnet when is requested.

==Flash the Modified Firmware==
Move the T-CHU7DEUC directory and all of its contents to an USB drive, plugin the USB drive into your TV and manually start the upgrade via the appropriate menu entry on your TV.

==Enable telnet==
[http://download.samygo.tv/SamyGO%20Applications/SamyGO%20Telnet%20Enabler%20v0.01.tar.gz Download SamyGO Telnet Enabler Program] extract it to your USB Flash, then plug it to TV.
Using the Content Library from Pup-Up menu, select USB, then under '''Game''' Menu, select and start SamyGO application once.
TV will goes black than returns to menu. This will enable your TV's telnet once.

==Add Auto Start Scripts==
Connect to your TV via telnet. If you use windows, you can use a command prompt or better [http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe PuTTY]. *nix guys just use a console.
telnet 10.0.0.15

The default username is root with no password.

===Enable Telnet and Back-Door===
This will enable Telnet and also open back-door for fixing boot-loop situations.

You firstly need to create and add info to SamyGO.sh which is what the TV is trying to boot from in rc.local
$ vi /mtd_rwarea/SamyGO.sh

Now add the following:
#!/bin/sh

# Enable Telnetd
mount -t devpts devpts /dev/pts
telnetd
sleep 20

# Open back-door for fixing boot-loop situations
sleep 20 # Allow USB stick to settle
USB="/dtv/usb/sda1" # USB mount-point

if [ -f $USB/usb.sh ];then
$USB/usb.sh # USB-File detected.
else
if [ -f /mtd_rwarea/mtd_rwarea.sh ];then
/mtd_rwarea/mtd_rwarea.sh # Run normal startup script
fi
if [ -f /mtd_rwarea/mount.sh ];then
/mtd_rwarea/mount.sh # Run mount script
fi
# Alternatives of Samsung WiFi Link Stick
# You need to download the new mods and place them in /mtd_rwarea/drivers/
if [ -f /mtd_rwarea/.wifi-rt2870 ];then
rmmod rt2870sta # Unloading original rt2870sta
sleep 5
insmod /mtd_rwarea/drivers/rt2870sta.ko # Loading modified rt2870sta
fi
if [ -f /mtd_rwarea/.wifi-rt73 ];then
rmmod rt73 # Unloading original rt73
sleep 5
insmod /mtd_rwarea/drivers/rt73.ko # Loading modified rt73
fi
fi

exit

If you don't know how to use vi save it to your usb stick and copy it or edit the file with vi and use ":wq!" without the quotes to exit and save the file.

Now you need to change the permissions on the file
$ chmod 755 /mtd_rwarea/SamyGO.sh

If you do not wish to use auto mounting or anything else you can stop here, just reboot your TV and confirm telnet is enabled. Or carry on to enable mounting.

===Enable Mounts===
If you wish to use auto mounting NFS/CIFS/SMB you will need to edit /mtd_rwarea/mount.sh
$ vi /mtd_rwarea/mount.sh

Add the following to mount.sh
#!/bin/sh

# If /mtd_rwarea/.nfs Exists then Mount NFS Shares on Virtual USB
# touch /mtd_rwarea/.nfs if you wish to use NFS Shares and mount on a Virtaul USB

if [ -f /mtd_rwarea/.nfs ];then
echo "Mounting NFS Shares on Virtual USB"

# Set NFS Settings

fi

if [ -f /mtd_rwarea/.nfs_unmount ];then
echo "Unmounted NFS Shares"
umount $VUSB/$NFS1
umount $VUSB/$NFS2
umount $VUSB/$NFS3
umount $VUSB/$NFS4
rm -Rf /dtv/usb/sda4
rm -Rf /mtd_rwarea/.nfs_unmount
fi

You will need to edit the "# Set NFS Settings" section and also decide if you wish to use a virtual USB stick to mount your shares on or not. I do not see the point in keeping a USB stick in just for mount points hence the mounting to a virtual disk. On some TV's this does not work, however, so then you will be forced to use a real USB stick.

Now you need to change the permissions on the file
$ chmod 755 /mtd_rwarea/mount.sh

If you are going to use the NFS mounting you need to touch /mtd_rwarea/.nfs-usb (ADD SMB AND CIFS)
$ touch /mtd_rwarea/.nfs-usb

Reboot the TV and watch the magic :)

How to enable Telnet on samsung TV's

2009-12-17T19:27:49Z

Kilroywashere: /* The Safe Way */

(by dynamic1969, edits and extensions by marcelr, erdem_ua, suggestions by olivluca, grajen)

If you are a novice, then I recommend you take some time to read and understand what you are doing first! THIS CAN BRICK YOUR DEIVCE !!

Read below for a detailed HowTo of the steps taken :

==The Safe Way==
*Using SamyGO Telnet Enabler Samsung TV application, you can enable telnet of TV without changing firmware.
Enabling telnet with this program is not dangerous '''but''' with wrong telnet commands, still you have a chance to brick your TV.
Download this program to your USB Flash, then plug it into your TV. Using the Content Library from the Pup-Up menu, select USB, then under '''Game''' menu, select and start the SamyGO application once.
The TV will go black and then returns to the menu. This will enable your TV's telnet for one session only. When you reboot your TV (switch off and back on) you need to reopen telnet via the menus.
I advise you to use the Automated script if you plan to do some development on your TV. If you just want to have look how things work, the safe way is better.
[http://download.samygo.tv/SamyGO%20Applications/SamyGO%20Telnet%20Enabler%20v0.01.tar.gz Download SamyGO Telnet Enabler Program].

== Prerequisites ==
(if you do not have ALL of these: Google is your friend, at least for the software):

*a Samsung TV attached to your local network.
*a hex editor.
**Linux : okteta and many others
**Windows: flexhex, neo, and many others.
*a crc32 checksum calculator.
**Linux : okteta 0.3 or later, check, minicrc, etc...
**Windows: flexhex, be wary of little endian (byte-reversed) checksums, possibly others
*xor encryption/decryption software.
**Linux : okteta 0.3 or later, crypt-xor, [http://www.habets.pp.se/synscan/programs.php?prog=xor-analyze xor-analyze], etc...
**Windows: flexhex, possibly others
*a normal ASCII editor.
**Linux : emacs, vi, gedit and and many more.
**Windows: notepad (Or a word processor. Be careful to save in ascii mode, .txt format)
*a telnet client.

== Hacking the Firmware ==
To acquire telnet access to your tv, do the following:

*Download the firmware package for your tv from the Samsung website and unpack it. As an example in this HOWTO, the T-CHU7DEUC.exe file for a ue40b70xx is taken. This will also work on any other xor-encoded firmware. Just replace the T-CHU7DEUC in this howto with your firmware name. When working on a linux box, you can unpack it with wine, unrar, or p7zip (just run `7z x <exe>`).
*Decrypt exe.img.enc in the T-CHU7DEUC/image directory using an xor decrypter with key "T-CHU7DEUC" (the firmware root directory name) and name it exe.img
*Check the CRC32 checksum of your decrypted file (exe.img). It should match the checksum (8-digit hexadecimal number), <xxxxxxxx> given in validinfo.txt _exactly_:
*007_exe.img_xxxxxxxx*011_appdata.img_126fb41f
If the checksums don't match, check the following: Is the downloaded file not corrupted? Is your decryption flawless?
*Using a hex-editor, make the following changes to the contents of rc.local in the decrypted exe.img file: locate the lines:

export KF_LOG=/dev/null '''#Remove engine logging.'''
cd /mtd_exe/

./exeDSP

and replace just the text element marked '''bold''', as shown below:

export KF_LOG=/dev/null''';/etc/telnetd_start.sh&'''
cd /mtd_exe/

./exeDSP
-> For safety reasons it is recommended that you don't miss the "&" at the end ( this is not yet considered in the SamyGo Script YET! )

Make sure you do not change the length of the image file. To be on the safe side, replace any unprintable characters on the changed line with spaces, but _keep_ the linefeed (0x0a)

And remember: Think before you type.
*Re-calculate the CRC32 checksum for the updated image.
*Using a normal ASCII editor, update validinfo.txt in the T-CHU7DEUC/image directory with the new CRC information: Replace xxxxxxxx in this line with the newly calculated checksum (8 hexadecimal digits, be aware of leading zeros):
*007_exe.img_xxxxxxxx*011_appdata.img_126fb41f
*Encrypt exe.img again, using xor encryption with key "T-CHU7DEUC" and copy it into the T-CHU7DEUC/image directory. Name it "exe.img.enc"

=== Flash to TV ===
*Move the T-CHU7DEUC directory and all of its contents to an otherwise empty USB drive, plugin the USB drive into your TV and manually start the upgrade via the appropriate menu entry on your TV

=== Result ===
*After upgrade, open a shell and start a telnet session on your tv:

$ telnet aaa.bbb.ccc.ddd

with aaa.bbb.ccc.ddd your tv's IP-address. when prompted, log in as <root>
This is what you'll see, when connected:

$ telnet aaa.bbb.ccc.ddd
Trying aaa.bbb.ccc.ddd...
Connected to aaa.bbb.ccc.ddd.
Escape character is '^]'.

localhost login: root
-sh: id: not found
#
You can now start typing commands. For available commands visit the normal places: /bin, /sbin, /usr/bin and /usr/sbin

== Browsing the Firmware ==

Decoding the ''run.sh.enc'' script shows that a bunch of images may be present and will automatically be flashed if found. This includes the kernel, the root filesystem, the u-boot bootloader, and the aux filesystems (below). The former seem to require loading over the USB serial though?

The ''exe.img.enc'' file, once decrypted, can be mounted as a normal FAT filesystem. Under Linux, you can do:
$ mkdir exe-dir
$ sudo mount -o loop -t vfat exe.img.dec exe-dir/
$ ls exe-dir/
Comp_LIB/ EXE_IMG_VER JadeTarget prelink.conf samdrv.ko
ddr_margin Factory.dat JadeTarget.cfg rc.local SpecialItemNumber.txt
edid/ game_lib/ LifeScenario ReleaseInfo value.bin
exeDSP InfoLink/ prelink.cache $rfs_log.lo$ YWidget_LIB/

The ''appdata.img.enc'' file, once decrypted, is a normal squashfs image (albeit an old 3.0 version). So if attempts to loop mount this image fail with:
$ mkdir app-dir
$ sudo mount -o loop,ro -t squashfs appdata.img.dec app-dir/
mount: wrong fs type, bad option, bad superblock on /dev/loop/1,
$ dmesg | tail -n1
SQUASHFS error: Major/Minor mismatch, older Squashfs 3.0 filesystems are unsupported

Then you can use unsquashfs from [http://squashfs.sourceforge.net/ squashfs-tools] to unpack it:
$ unsquashfs appdata.img.dec
Parallel unsquashfs: Using 2 processors
2203 inodes (4374 blocks) to write

[===============================================/] 4374/4374 100%
created 2190 files
created 102 directories
created 13 symlinks
created 0 devices
created 0 fifos
$ ls squashfs-root/
APPDATA_IMG_VER Font/ lib/ resource/ widget/
Demo/ Images_960x540/ QPI_DTV_AUDIO.ts testPlay.ts

==Automated Way==
*If you know what you are doing and are simply looking for a tool that will do all of the hacking for you, then you can use [http://forum.samygo.tv/viewtopic.php?f=5&t=13&p=22#p22 SamyGO script] (requires python installed on your system) to make all modifications to your firmware. This will produce an exe.img ready to [[#Flash to TV]].

===Usage===
python ./SamyGO.py <path to extracted directory from firmware>
example: python ./SamyGO.py ./T-CHL7DEUC/

During the patching process you will be asked to use Enable Telnet or Advanced Mode.

Enable Telnet or Advanced Mode on image( T/a )?

*If you simply wish to just enable telnet on startup select "T"
*If you wish to automount shares and telnet then select "a"

Once the SamyGo Firmware Patcher has completed the patch please flash the new patched firmware to your TV.

===Advanced Mode===
If you selected Advanced Mode you will need to create a file called /mtd_rwarea/SamyGO.sh and set the permissions to 755

Once you have flashed your TV you will need to use the [http://download.samygo.tv/SamyGO%20Kernel%20Modules/SamyGO%20Applications SamyGO Telnet Enabler Program], to enable telnet. This is a once off.

Once you have enabled telnet using [http://download.samygo.tv/SamyGO%20Kernel%20Modules/SamyGO%20Applications SamyGO Telnet Enabler], telnet to your tv and create /mtd_rwarea/SamyGO.sh

# vi /mtd_rwarea/SamyGO.sh

Add the following to SamyGO.sh
#!/bin/sh

# Enable Telnetd
if [ `cat /proc/mounts | grep -c "/dev/pts"` -lt "1" ] ; then
echo "telnetd Enabled"
mount -t devpts devpts /dev/pts
telnetd
else
echo "/dev/pts is mounted"
fi

# Open back-door for fixing boot-loop situations
sleep 20 # Allow USB-stick to settle
USB="/dtv/usb/sda1" # USB mount-point

if [ -f $USB/usb.sh ];then
echo "USB-File detected"
$USB/usb.sh
else
echo "Running Normal SamyGO Startup"
/mtd_rwarea/SamyGO.sh # Run normal startup script
fi
exit
Set the right permissions
# chmod 755 /mtd_rwarea/SamyGO.sh

Now reboot your TV and you ready to rock and roll....

SamyGO Extensions Pack

2009-12-06T21:54:33Z

Kilroywashere: /* Copy extensions to tv's flash memory */

== What are "SamyGO Extensions" ==

:"SamyGO Extensions" enhance your tv's functionality without patching or modify the firmware!
:*Access your network shares and network-storage devices as pseudo usb-devices (it is possible to seek and ff in this files + more media container are supported)
:*Enables ssh access to your tv (not telnet! as client you can use [http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html putty])
:*Additional tools for advanced users like ssh, mksquashfs and checksum-calculator (for sure change from version to version)

== Where can you find "SamyGO Extensions" ==

:the released version:
::http://download.samygo.tv/
:latest beta:
::http://linux.zsolttech.com/Samsung/

== Can you brick your tv with this extensions ==

:answer is simple:
::no, but it can kill your cat, burn your house and make horny things with your girlfriend! in worst case your tv shut down and power on again.
::except you make changes in the scripts and you didn't know what you done
::if you change any of the scripts you also loose the "arris warranty" ;-)
::if you need assistance for your own scripts you can ask in:
:::http://forum.samygo.tv/viewforum.php?f=4
:::but ask before you bricked your tv!

== Is this stuff compatible with your tv ==

:generaly binaries and kernel modules are for ARM architecture
:look at the samsung site, download and extract the firmware for your tv and
:check the resulting directory name:
:*T-PRLAUS -> binaries may work, kernel modules rather not
:*T-AMBAUSC -> binaries may work, kernel modules may also
:*T-CHE7AUSC, T-CHE6AUSC, T-CHE7AUSC, T-CHU7DEUC, T-CHL7DEUC -> binaries yes, kernel yes (pls. search in forum, i made all tests on UExxB7020 => T-CHU7DEUC)
:*T-CHUCIPDEUC -> binaries may work, kernel modules may also
:*T-CHLCIPDEUC -> binaries yes, kernel modules yes ([http://www.hifi-forum.de/viewthread-151-11476.html posted by user sondeu])
:*T-AMBDFR -> binaries not, kernel modules also not (Renesas SH not ARM)
:*T-RBYDEU -> binaries not, kernel modules also not (Renesas SH not ARM)
:your tv have to support games in "content library" and "usb movie", pls. consult the manual

== General usage ==

:extract the zip file to usb-pen 
:mv SamyGO directory into the [http://en.wikipedia.org/wiki/Root_directory root-directory] of the usb-pen
:connect usb-pen to tv
:wait few seconds for automatic usb connection menu on tv
:select "content library"
:go to usb -> games, and select "SamyGO Extensions" (with "ok" button on remote-control)
:after the colored screen goes away, up to ~27 sec. (this is true up to SamyGO All Extensions v0.03, later versions will have some kind of control-panel)
:exit from "content library" and go to "media play" ("media.p" button on remote-control)
:select source (red button on remote-control)
:depends on your network services you can see new usb-sources (this are "faked" devices)
:*"UPNP Server"
:*"Samba Server"
:*"NFS Server"
::select one of them, pick what you want to see (pictures, music or video) than you should see your server(s), enjoy your media(s)

== Copy extensions to tv's flash memory ==

:on some models it is possible to copy contents to tv's memory in the
:same way you can copy "SamyGO All Extensions" pack to flash
:yellow button ..., pls. look into the manual or search in forum

:If you can't copy "SamyGO All Extensions" via TV you can do it with a telnet or ssh connection

cp -a /dtv/usb/sda1/SamyGO /mtd_tlib/GGame/

== What you have to do before ask 1000 times answered questions ==

#Read here
#::http://forum.samygo.tv/viewtopic.php?f=5&t=96#p540
#::so you now know how to disable unneeded services and where to set the username and password for windows shares (for editing the init-scripts under windows -> use [http://notepad-plus.sourceforge.net/de/site.htm Notepad++] or an other editor that can handle unix files!!)
#File attributes
#::don't copy/extract the extensions on ntfs formated usb-hd just vfat (fat32)
#:::keep the execute attributes correct!
#::the init-scripts have the execute bit to set, this is already done
#:::but if you extracted the archive to a NTFS formated usb-hd this setting
#:::is lost! (tv mounts ntfs with special options)
#:::so you have to use an usb-pen or reformat your usb-hd with
#:::vfat before use it.
#Media file sizes
#:upnp (djmount), cifs and nfs, i tested video files up to 8813360067 bytes (h264/720p mkv)
#:server software:
#:* upnp: ushare 1.1a (DLNA disabled!)
#:* cifs: samba-server 3.2.3
#:* nfs: kernel level nfs server (nfsd4)
#::ff and seek is (over wifi network) tedious, you can play around with mount parameters in:
#:::SamyGO/etc/init.d/04_04_samba.init
#:::SamyGO/etc/init.d/03_03_nfsmount.init
#:if you can't access/play your big fat files try to split them, problem is at server side not in "SamyGO Extensions" or TV
#Subtitles
#:tested *.srt files -> no problem over upnp (djmount), cifs and nfs
#:naming sheme:
#::MyMovie.srt
#::MyMovie.wmv

== Advanced usage ==

If you have started the extensions, [[#General_usage|General usage]]
:you can ssh to your tv (ssh root@<tvs ip>)
:after the login you can execute the command
::<tt>source /dtv/SGO.env</tt>
:so you get an usable enviroment (sets PATH and LD_LIBRARY_PATH for the binaries)
:to get more extensions working, you can copy them into the SamyGO directory structure (like SamyGO-WiFi-Extension-Addon)

== Easter eggs and customize ==

SamyGO ChanEdit - Chanel Editor

2009-12-06T19:07:05Z

Kilroywashere: /* Channel Import/Export Menu */

=SamyGO ChanEdit=

With SamyGO ChanEdit you can edit your channel list of your Samsung TV Set using any Computer able to run a Java VM supporting SWT. This makes moving channels around a lot easier. Also the list can be extended by channels that are not found by the channel search engine. For example Sky.de interactive channels, which the editor can add automatically when a list containing Sky.de channels is loaded.

==Channel Import/Export Menu==
First you have to connect a USB drive with a FAT/FAT32 filesystem to your TV.

When the TV is switched ON press '''Volume Down''' [[File:Volume_down_key.png|30px]] once and then press '''the Enter [[File:Enter_key.png|30pxâ]] button for 10 seconds'''. This will display the "Channel Import / Export" Menu.

If this doesn't work, check that "Speaker Select" in "Sound Menu" is set to "TV Speaker". Anynet+ (HDMI-CEC) should be disabled.
[[File:Channel_Import_Export.png|300px|left|thumb|Channel Import / Export]]
 
Choose '''USB to TV''' for channeldata import or '''TV to USB''' for copying the channeldata to the USB drive.

When everything worked correct you'll find the following data on your USB drive:

kilroy@kilroy:~$ ls -la /media/USB2GB/T-CHLCIPDEUC/Clone/
total 744
drwx------ 2 kilroy kilroy 4096 1980-01-01 00:00 .

Now you can edit the channel list (for the moment only map-CableD for DVB-C) stored on the drive using SamyGO ChanEdit.

After that just use the same procedure to import the list again.

==Downloading and Installing==
Download the SamyGO ChanEdit (and required Java library for you OS) from [http://download.samygo.tv/SamyGO%20Applications/ SamyGO Applications] file download area.

===Ubuntu 9.10 amd64===

You have to download the files '''SamyGO ChanEdit-v0.31.tar.bz2''' and '''SamyGoChanEd_lib-Linux-GTK-x86_64.tar.bz2''' 
Ubuntu 9.10 is coming with openjdk-6-jre but you can also install Java from SUN.

# sudo aptitude install sun-java6-jre
[ -d ~/bin ] || mkdir ~/bin
tar xjf Downloads/SamyGO\ ChanEdit-v0.31.tar.bz2 -C ~/bin/
tar xjf Downloads/SamyGoChanEd_lib-Linux-GTK-x86_64.tar.bz2 -C ~/bin/SamyGO\ ChanEdit-v0.31/
ln -s ~/bin/SamyGO\ ChanEdit-v0.31/SamyGoChanEd.jar Desktop/SamyGoChanEd.jar

With right mouseclick at the SamyGoChanEd.jar icon choose under '''Properties -> Open With:''' ''OpenJDK Java 6 Runtime'' (or ''Sun Java 6 Runtime'')

==Modifying Channel List==
You can modify your Channel list via SamyGO ChanEdit.

The files are under your USB at T-CHxxDEUC/Clone directory.
With Version 0.31 currently only map-CableD for digital Cable Channels is editable.

Dumping and Flashing images by hand

2009-12-06T13:50:14Z

Kilroywashere: /* Manual flashing steps */

The steps outlined below allow the flashing of an image directly into the flash of your TV, without using the offical upgrade process of the TV. The example shown below is for flashing a modified exe.img on a UExxB70xx. 
There is no need to flash app_data Image, if you are just flashing modifications of the same exeDSP Version. 
'''In any case you need to ensure that you erase the respective flash before overwriting it.'''
== Device files used ==
Find below the device files for different areas of the firmware for FW types listed ( this information is taken from the run.sh file and was not validated! )
=== T-CHL5DSEUC, T-CHL5DEUC and T-CHU7DEUC ===
*BOOTLOADER_DEVICE='''/dev/bml0/2'''
*FNW_DEVICE='''/dev/bml0/4'''
*KERNEL_DEVICE='''/dev/bml0/5'''
*RFS_DEVICE='''/dev/bml0/6'''
*BOOT_DEVICE='''/dev/bml0/7'''
=== T-CHL5DSEUC and T-CHL5DEUC Specific ===
*EXE_DEVICE='''/dev/stl0/8'''
*APPDATA_DEVICE='''/dev/stl0/9'''
=== T-CHU7DEUC Specific ===
*EXE_DEVICE='''/dev/bml0/8'''
*APPDATA_DEVICE='''/dev/bml0/9'''

=== For All Devices ===
*It's better to conceive the structure of your TV by '''df''' tool.
You can check your "'''df'''" output. Here is mine on LE40B650T2W which uses T-CHL7DEUC firmware

# df
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/tbml6 3136 3136 0 100% /
none 10240 0 10240 0% /dtv
/dev/tbml7 1024 1024 0 100% /mtd_boot
none 10240 0 10240 0% /mtd_ram
/dev/stl0/14 11224 1778 9446 16% /mtd_rwarea
/dev/tbml10 61400 52440 8960 85% /mtd_exe
/dev/tbml11 29312 29312 0 100% /mtd_appdata
/dev/stl0/13 193536 160000 33536 83% /mtd_tlib
/dev/stl0/15 51160 1976 49184 4% /mtd_contents
/dev/stl0/16 90012 16344 73668 18% /mtd_down
/dev/stl0/12 152576 224 152352 0% /mtd_wiselink
/dev/stl0/17 89072 176 88896 0% /mtd_swu

Interpretation of this list is like that:

As you can easily understand mount of '''/mtd_exe''' means EXE_DEVICE is that '''/dev/tbml10'''.

And '''/''' describes that is ROOT device at '''/dev/tbml6'''.

*EXE_DEVICE = /dev/tbml10
*ROOT_DEVICE = /dev/tbml6
*APPDATA_DEVICE = /dev/tbml11
*BOOT_DEVICE = /dev/tbml7

You have to aware that, there is some devices not shown on '''df''' commands like bootloader or like kernel devices...

== Manual flashing steps ==
*(1) Prevent TV from rebooting when exeDSP is stopped
/mtd_boot/MicomCtrl 23
*(2) Stop exeDSP binary
killall -9 exeDSP
*(3) Unmount the respective directory
umount /mtd_exe
*(4) Take a backup of the current image in the flash.
bml.dump /dev/bml0/8 /mtd_swu/exe.img.orig
If you dont have bml.dump tool in your firmware, than you can use '''dd''' or '''cat''' tool too.
cat /dev/bml0/8 > /mtd_swu/exe.img.orig

dd if=/dev/bml0/8 of=/mtd_swu/exe.img.orig
*(5) Move backup image to a safe space ( e.g. USB )
mv /mtd_swu/exe.img.orig /dtv/usb/sda1
*(6) Copy Image to be flashed from your USB to /mtd_swu
cp /dtv/usb/sda1/exe.img /mtd_swu
-> this is the safest way, even though flashing directly from USB-Device may also be possible, which I have not tested
*(7) Erase the flash before flashing the new file
bml.erase /dev/bml0/8
*(8) Perform the actual step of flashing the file.
bml.restore /dev/bml0/8 /mtd_swu/exe.img
->Flashing progress will be shown 0% ... 100%. Don't interrupt this process!!
*(9) Mount the updated image( afterwards check out content and ensure it mounts without problems and looks ok from a content perspective. )
mount -t auto /dev/tbml8 /mtd_exe 
*(10) Starting exeDSP 
/mtd_exe/rc.local
-> If something went wrong and your exeDSP doesn't start up properly, then you can flash back your backup ".orig" image following steps 3-9. -> Don't worry, if you see your screen upside down after re-starting exeDSP ;-) as
the exeDSP binary seems to expect a freshly initialized HW to start-up properly 
 '''Attention:'''This process does not validate the correctness and validity of the file being flashed. THIS IS YOUR RESPONSIBILITY!!!
