I have accessed my TV with telnet, but now telnetd don't start because the injecting blocks the kernel and causing a kernelpanic.

netcat gives no output all the time the tv is on.

i think there is no other way as to call samsung service :cry: :cry:

How about exlink and u-boot?
Boot external kernel via tftp or from usb and corect samygo.sh ;)

If do you have u-boot access, you can boot external firmware but I don't know how it is made on CI+ series.
Also just character input could be disabled from debug menu by changing some memory addresses. But I guess there is no time for a such operation by hand. Might be work with automated scripts from PC.

I don't know exactly but I remember that (petergray/earlgray ?) introduce a way to enable char input at CI+ series....
When TV has crashed, it generated coredump if USB stick is connected.He analyzed codedump of TV at his computer.
Than used "Debug Menu" to change some memory address and viola...

I think you could find detailed description at forum... I remember that he wrote it down somewhere here...

Thank you Erdem, i will test this.

How about starting more than one injection over samygo.sh?
Only remove the & or is there some other customizing necessary?

I think you don't needed to run more than 1 injection. This might corrupt some memory...
You can place injection script to some other file and could call it with &...
But you cannot have it in SamyGO.sh. If you put & at every injection line, that will start new threads for each of injection and it could be problematic.
