The file-system used in the the recent Samsung TVs is "RFS". Its proprietary nature and consequently so the absence of an according Linux RFS-Module in the standard Linux distributions makes it currently impossible to modify files by simply mounting the respective image as "RW", modifying it and saving the respective image again. This is the reason why currently all changes are done via patching of the image-binaries.

How to enable Telnet on samsung TV's

2009-12-07T15:15:07Z

Vapier: add a section for poking into the firmware contents

(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%20Kernel%20Modules/SamyGO%20Applications 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....

Is my TV supported?

2009-12-07T14:03:47Z

Vapier: link in the new compatibility page

Q: My TV model is xxxxxx. Is this model supported?

A: Check the [[Compatibility|list of currently supported devices]].
If your model is not in that list, you can still try below steps:

If your model has no P letter after model number, (like LE40B650'''T2W''') Chances are higher that one of the hacks from our WIKI listed below may still work to get you access to your device. Try them out preferably in the
order listed:
# You have a LAN jack? If you have, you can use the Telnet Enabler application to enable network access.
# If Telnet Enabler Application is not working for you for whatever reason, then try to patch your firmware via SamyGO Firmware Enabler script to enable Telnet using [[How_to_enable_Telnet_on_samsung_TV's|this page]]
#After you can edit scripts on your TV - before doing so, ensure you have followed the steps on [[Open_backdoor_for_fixing_bootloop_situations|this WiKi page]]. This is a very important step and for your own safety!!!
#If you don't have LAN jack on your TV, than you have only one option: [[Enable_Serial_Console_on_non_CI+_Devices|Using service port via the ExLink cable]] to enter your TV's linux console.

If your model has P letter after the model number, (Like LE40B650'''T2P''' ) it means that your firmware is encrypted and your hardware has some extra security checks to prevent tinkering with your device's FW.
#Using Telnet Enable Application will enable Telnet, but you won't be able to run every program that you want. You can mount NFS shares but cannot use new kernel modules... Since firmware is encrypted, we cannot touch firmwares for enabling telnet on firmware downloaded from Samsung site ( yet! ).
#[[Enable_Serial_Console_on_non_CI+_Devices|Accessing the Linux console prompt via the Service Port using an ExLink cable]] is not yet supported for devices with encrypted Firmware but there is a hidden system menu that you may be interested in ( and could try to carefully play with it ).

You should also check out our [[http://forum.samygo.tv/index.php forum]] to see if and what other people may already have been able to do with your model type.
In any case, if you figured out some new features / possibilities on your model, you are more than welcome to share your knowledge in our [[http://forum.samygo.tv/index.php forum]] so that we can add / enhance our list of supported devices.

This is the reason why currently all changes are done via patching of the image-binaries.

The information provided here should help, that we get a RFS module compiled for our common Linux distributions

== Compatibility Overview ==

The Samsung TV model can be broken down like so:

<TYPE><REGION><SIZE><YEAR><SERIES><VARIANT>[misc details]

{| border="1" cellpadding="0" cellspacing="0"
|-
| Type:
|
{|
| L
| LCD
|-
| P
| Plasma
|-
| U
| LED
|}
|-
| Region:
|
{|
| A
| Australia
|-
| E
| Europe
|-
| N
| North America
|}
|-
| Year:
|
{|
| A
| 2008
|-
| B
| 2009
|-
| etc...
|}
|}

An example, the ''UN55B8500'' is an 8 series (500 variant) 55" LED TV in North America from 2009.

So typically, the firmware modifications here should work on TVs of the same type, year, and series.
