View source for Enable Network support on B550 and B6000 Series Devices

Instructions tested on TV model '''UA32B6000 firmware T-CHL5DAUC'''<br />
'''READ ALL BEFORE ATTEMPTING - ASK QUESTIONS IF ANYTHING UNCLEAR HERE: [http://forum.samygo.tv/viewtopic.php?f=2&t=956 Forum Thread]'''<br />
'''IMPORTANT:''' before beginning dump/backup all important partitions in case of bricked TV. <i>(for instructions see step 4)</i> hopefully not required if careful<br />
'''ONLY flash kernel after testing and all functions on TV working normally (eg. usb storage detection, access to serial console, remote control etc.)'''

==Step 2 - Test Modified Kernel Before Flashing To TV Memory==
:<code lang="text">
:<u><b>Test kernel image via u-boot with Exlink cable. (with usb drive prepared in step 1 plugged in TV usb port)</b></u>
:</code>
# Enter service menu, TV is initially '''off''', then on remote control hit '''{info}-{menu}-{mute}-{ON}'''
# Change setting for your RS232C interface to '''"debug"''' ( Control -> Sub Option -> RS-232 Jack -> [ Debug | UART | Logic ] )
# Change setting for Watchdog to '''"off"''' ( Control -> Sub Option -> Watchdog -> [ on | off ] )
# Exit service menu & switch off TV.
# Connect computer to TV's 3.5mm service port with exlink cable and start telnet. (to test connection, switch on & off TV to see output in telnet)
# Press and hold '''"~" (shift + "~")''' and while holding, switch on TV. Then quickly hit '''"enter"''' before 3 seconds delay expires.
# Select '''"0"''' (zero) and hit '''"enter"'''. to jump to uboot prompt.
# Type or copy paste following command and hit '''"enter"'''
#: <pre>
#: setenv bootargs root=139:6 console=ttyS1;usb start;fatload usb 0 61000000 /image/uImage;bootm</pre>
# TV should start like normal, booting modified kernel image off usb drive.
# If success and TV started and operated like normal.  Proceed to step 3.
#:<br />
==Step 3 - Flash Modified Kernel To TV Memory==
:<code lang="text">
:<u><b>Flash usb drive prepared in step 1 to TV memory. (WARNING. no option in TV 'software update' to revert to previous firmware)</b></u>
:</code>
# Plug usb drive in TV usb port and power on TV.
# In TV menu select ''''support'''', ''''software update'''', ''''by usb'''' and ''''ok'''' to search usb for update.
# When update found select ''''ok'''' to continue update. Do NOT switch off TV or unplug usb.
# TV will reboot itself to complete update. Update process was under 30 seconds on my TV.
# If successfully flashed TV's kernel will be network enabled and ready for testing and setup.  Proceed to step 4.
#:<br />
==Step 4 - Dump / Copy TV Boot Partition For Modification==
:<code lang="text">
:<u><b>Dump your TV's boot partition. Fat formatted usb drive plugged in TV required</b></u>
:</code>
# Telnet to TV with exlink cable connected to TV and TV powered on. 
# When fully started and TV's boot output in telnet has stopped enter following commands to begin serial console (shell).
# Type <b>"debug"</b> at the invisible prompt to enable your serial console.
# Type <b>"1198282"</b> and hit <b>"enter"</b>, for '<u>Top Debug Menu</u>'.
# Type <b>"11"</b> and hit <b>"enter"</b>, for '<u>TD Debug</u>'.
# Type <b>"04"</b> and hit <b>"enter"</b>, for '<u>spl Debug</u>'.
# Type <b>"68"</b> and hit <b>"enter"</b>, for '<u>Shell</u>'.

==Step 5 - Modify TV Boot Partition Using TV and SamyGO-Extensions==
:<code lang="text">
:<u><b>Using SamyGO-Extensions and TV as OS follow steps below to edit 'rc.local' and '.version' files.  Fat formatted usb drive required</b></u>
:</code>
# Download [http://download.samygo.tv/SamyGO%20Extensions%20Packs/Old%20Releases/ SamyGO-Extensions] (version <b>r08</b> for unsquashfs & ckvfs tools) from SamyGO file downloads and extract to usb drive. Download link:''' [http://download.samygo.tv/SamyGO%20Extensions%20Packs/Old%20Releases/]'''
# Copy boot partition <b>'dev_bml0_07.img'</b> (created in step 4) to root of usb drive and insert into TV usb port.
# Telnet to TV with ex-link cable and begin serial console (as described in step 4). 
# Load/run SamyGO-Extensions to enable tools required to modify boot partition. Type command below and hit <b>"enter"</b>. (Note. init script setup not required to perform this)
#: <pre>sh -x /dtv/usb/sda1/SamyGO/rcSGO</pre>
# cd to usb root and inspect <b>'dev_bml0_07.img'</b> file. Type 2 commands below and hit <b>"enter"</b> after each command. Take note of output result.

#: cd /dtv/usb/sda1
#: unsquashfs -s dev_bml0_07.img</pre>
# Extract  <b>'dev_bml0_07.img'</b> type command below and hit <b>"enter"</b>
#: <pre>unsquashfs -dest dev_bml0_07 dev_bml0_07.img</pre>
# Edit <b>'/dev_bml0_07/.version'</b> file with <b>'vi'</b> editor, increasing version number by 1 and save file.  See example below done for my TV.

##Alternatively insert line <b>'/mtd_rwarea/rcSGO &'</b> instead for 'SamyGO-Extensions' to load modules, mount networks, enable ssh and using injectso etc. I use 'SamyGO-Extensions' and start with 'SamyGO.sh'. 
# OPTIONAL. If you know what you are doing delete unneeded files (I safely deleted <b>'dev_bml0_07/modules/install_ko.sh'</b>)
# OPTIONAL. Copy new modules like <b>'rt73.ko'</b>, <b>'rt2870sta.ko'</b>, <b>'cifs.ko'</b> & <b>'nfs.ko'</b> etc, to <b>'dev_bml0_07/modules'</b> folder. Not required if planning to use 'SamyGO-Extensions'  <i>(To do instructions at end)</i>. 
# Fix ownership to <b>'dev_bml0_07'</b> files and sub-files. Type command below and hit <b>"enter"</b>.
#: <pre>chown -R root:root dev_bml0_07</pre>
# Create new <b>'boot.img'</b> to be flashed to TV in step 6. Type following command and hit <b>"enter"</b>.
#: <pre>mksquashfs dev_bml0_07 boot.img -le -b 65536</pre>
# Again inspect <b>'boot.img'</b> type following command and hit <b>"enter"</b>. Compare result with first inspection result preformed above.
