Hi,

Is this menu only accessible with the serial port or also at the Service menu ? Could this also work at the actual C-Series ?

If yes this could be a way to get Telnet access to the TV or am I wrong ?

Hi,
great work :)

Right before executing the emergency.sh script, exeDSP issues a "killall authuld",
have you tried executing the custom shell script within the first minute of a
reboot ?
Would be very interesting if it keeps running nonetheless (but I guess it won't).

Also, have you found a way to autostart a script without user interaction ?
I thought about modifying resolv.conf which resides on /mtd/rwarea and inserting
backticks into it to launch shell commands, but as it is only a configfile that won't work.
All I can think of right now would be another PC (or atmega8 etc) connected to the
Exlink-Port which launches a script through the serial-kernel-check-disable-method.

cu Cyberdemon :)

I can confirm that there are different passwords, since my TV just does nothing after entering your PW.

@arris69
Does it matter if I execute these commands via the shell? If not, I attached the output.

Hi!
@petergrey

Code: Select all

SWU_T-CHL5CIPDEUC_002005_I02_EK000DK000_090901
I'm on 2005 Firmware version on my B550!

And I wrote a little Tool for enabling shell access via ExLink using the commands you showed in the other thread. I was tired of typing the numbers :D
Just connect your turned off TV to PC and follow the instructions. If anyone cares i can post my ugly Delphi Source :lol:
Posted this already in the other thread, will upload here too.
