Forced revert back to older firmware

2010-04-30T09:42:31Z

This is procedure for reverting back to an older firmware. It can help you if you upgraded TV to latest firmware accidentally.

'''But if your new TV comes with latest firmware already, this instruction cannot change anything for your TV.'''
[[File:Samy_horse.jpg | right]]
=Enabling Telnet=
With the latest firmware, Samsung disabled both Ex-Link console connection and external applications probably to stopping us. So you cannot create telnet connection to TV because you cannot use Telnet Enabler application. If you copied Telnet Application to TV's flash memory before you are lucky. But if you didn't please don't cry, here is the solution.

=Trojan Horse=

'''Historically:''' Trojan is a giant horse that has hidden soldiers in it and it was used first at Troya A.D.2500-3000, which is in Ãanakkale, Turkey now. Soldiers leave a huge wooden horse behind them as a gift and fade away... Enemies take that giant horse inside of city walls. But when the night comes, soldiers hidden in the horse get out and open the gates... :)

So we follow the same pattern here. Delete some content library tool, something like "children stories", then download new one from [http://www.samsung.com/uk/consumer/learningresources/media2.0/library_download.html# Samsung] and use downloaded file as Trojan horse. After downloading file, place [[SamyGO Telnet Enabler]] folder to inside it, then move files to USB and plug in to TV. After copying content in to TV's Flash, you can run Telnet Enabler from Content Library that enables Telnet (or open the gates :) ).

=Forcing to Enable Alternative Firmware=
After some firmware upgrades, Samsung disable reverting firmware back to older state.
Actually we were using as a solution for that, flashing mtd_exe and mtd_appdata partitions via manual flashing procedure over telnet connection, enabled with Telnet Enabler application.

Instead of flashing dump of older firmware over actually used partition which is risky, we can switch to older firmware via this simple hack. This way is safer than other approaches. Code bellow unhides alternative firmware in TV.

'''Notice: These code lines are as an example for B650-B750 devices, so firmware name contains T-CHL7DEUC, for other TV's you need to use corresponding version string of previously installed firmware and corresponding missing Version file (Version.0 or Version.1)!!!'''

After this, disabled "Alternative Firmware" selection in standard TV's Support / Software Upgrade Menu becomes enabled and populated again. You can switch to previously flashed firmware and then flash some safe firmware over the latest firmware which has restrictions.

Forced revert back to older firmware

2010-04-30T07:27:04Z

Ji035453:

This procedure for reverting back to an older firmware can help you if you upgraded TV to latest firmware accidentally.

'''But if your new TV comes with latest firmware already, this instruction cannot change anything for your TV...'''
[[File:Samy_horse.jpg | right]]
=Enabling Telnet=
With the latest firmware, Samsung disabled both Ex-Link console connection and external applications probably to stopping us. So you cannot create telnet connection to TV because you cannot use Telnet Enabler application. If you copied Telnet Application to TV's flash memory before you are lucky. But if you didn't please don't cry, here is the solution.

==Trojan Horse==

'''Historically:''' Trojan is a giant horse that has hidden soldiers in it and it was used first at Troya A.D.2500-3000, which is in Ãanakkale, Turkey now. Soldiers leave a huge wooden horse behind as a gift and fade away... Enemies take that giant horse inside of city walls. But when the night comes, soldiers hidden in the horse get out and open the gates... :)

So we follow the same pattern here. Delete some content library tool, something like "children stories", then download new one from [http://www.samsung.com/uk/consumer/learningresources/media2.0/library_download.html# Samsung] and use downloaded file as Trojan horse. After downloading file, place [[SamyGO Telnet Enabler]] folder to inside it, then move files to USB and plug in to TV. After copy to TV's Flash, you can run Telnet Enabler from Content Library that enables Telnet (or open the gates :) )

=Forcing to Enable Alternative Firmware=
After some firmware upgrades, Samsung doesn't let us revert firmware back to older state.
Actually we were using as a solution for that, flashing mtd_exe and mtd_appdata partitions via manual flashing from telnet connection, enabled via telnet application.

Instead of flashing dump of older firmware to actually used partition (which is risky), we can switch to older firmware via this hack. This way is more safe than other approaches. Lines bellow unhide alternative firmware in TV.

'''Notice: This code lines are for B650-B750 devices, so firmware name contains T-CHL7DEUC, for other TV's you need to use corresponding version string and corresponding missing Version file !!!'''

This way is more safe than other approach. Lines bellow will make TV use alternative firmware.

localhost login: root
-sh: id: not found
# cd mtd_rwarea/
# ls -al Version.*
-rwxr-xr-x 1 root 0 44 Jan 1 1980 Version.1
# cat Version.1
SWU_T-CHL7DEUC_003000_I02_EK000DK000_100125
# touch Version.0
# ls -al Version.*
-rw-r--r-- 1 root 0 0 Jan 1 1980 Version.0
-rwxr-xr-x 1 root 0 44 Jan 1 1980 Version.1
# chmod 755 Version.0
# ls -al Version.*
-rwxr-xr-x 1 root 0 44 Jan 1 00:00 Version.0
-rwxr-xr-x 1 root 0 44 Jan 1 1980 Version.1
# echo SWU_T-CHL7DEUC_002004_I02_ES000DS000_090816 >Version.0
# cat Version.*
SWU_T-CHL7DEUC_002004_I02_ES000DS000_090816
SWU_T-CHL7DEUC_003000_I02_EK000DK000_100125

So after this, disabled "Alternative Firmware" selection became enable. So you can switch older firmware and patch some safe firmware on to latest firmware which has restrictions.
