Le40B650 Firmware Downgrade HELP!!

[juusso]

Possible mistakes/errors:

1. Don`t use windows text editor (Notepad winword etc.) to edit script file. Use N++ instead.
If You are linux user here shouldn`t be any problem.

2. Copy game to TV memory and run Run this telnet ennabler instead another one (there are two "games"). Leave usb attached and go via Menu-Sources-Content Library-My Content(not USB!)-Children and run it from there, not via RC content button.

3. IP of TV must be setted manually, not automaticaly. Do You have ping from TV.

I attached

telnet.rar

file. Extract telnet.sh. Don`t edit it. Just replace with original one. It should work.
Fully automated method is based on Samygo Troja Horse. If it not work for any reason, this method will don`t work too. Try to use telnet-enabler as described in this topic.
As telnet client You can use SamyConsolefrom geo650. You need just keyboard attached to TV before You start this "Game" on TV. Off-course, You need UDN game with key from nurisam.com in this case too and working telnet.

I have little changed Samygo Trojan Horse. Now there are three possibilities, just two first are working:

• Activate Alternative firmware menu (no comments. This game does NOT enable telnet )
• Run Telnet Enabler (run it and enable telnet)
• Samygo Trojan Horse (Does nothing, don`t run it)

How to use:

• Enter Service Menu ( quickly push
  [MENU] [MUTE] [POWER] on your remote control )
  [*] Change setting (Control -> Sub Option -> Wiselink Write -> On )
  [*] Download attached file:

  telnet-enabler.tar.gz

  [*]Unpack and copy telnet-enabler folder to root USB and plug in to TV.
  [*] Enter Content Library Manager -> Select USB -> Select Children category.
  [*] Use Copy function on TV to copy Telnet Enabler as Trojan content to TV internal flash.
  [*] Return back to main manu in Content Library Manager and select again Children but from TV flash contents this time.
  
  [*]You can run it from: [Menu] -> [Source list] -> [USB] -> [Content Library] -> [My Contents] -> [Children]
  (this way USB must be attached even if You run it from TV memory, otherwise You don`t find USB in [Source list] )
  
  [*] Run Activate Alternative firmware menu
  [*]Wait while script makes a job, don`t power-off TV. There isn`t any message to inform You about it`s done.

(on LE40B653T5WXBT it took 50 sec). After approx. 2 minutes check Firmware upgrade menu, if there is Alternative Firmware active, choose it, TV reboots with new older firmware.
