you`ve surprised me (in bad meaning).

I think, you bricked TV because:

either:
  • you used not the latest version of FFB (versions under 0.5) and you used wrong images (from other TV models) to restore
or:
  • You used patched firmware and you got some errors during patching process. If you ignored errors and flashed it - it could cause TV brick.
Here are a lot of safety checks in FFB and flashing images from other models is (almost) impossible, just if patcher error occured.
I need all log files from USB you got. And more detail explanation what have you used and what have you did, to understand what went wrong and help you.

It could be, you flashed pre-patched firmware and it has errors... I hope you added files from archive [T-CHLDEUC]-u-boot.bin,[T-CHLDEUC]-fnw.bin and [T-CHLDEUC]-Image first time you used FFB? I think - yes, because you got it finished. Then prepare exlink cable, god, unpatched firmware and read a bit this thread. It is better to wait my assistance step by step, because if you aren`t good in linux, you could brick it totaly. I think you did not read instruction, because you`ve deleted log files from usb... :x
I edited FFB instructions for mandatory usage of original, not patched firmware for rollback process already .

I think you red this from readme file and how-to:

Code: Select all

IF NO SUCCESS OR TV BRICKED 

- TV rebots on any error during downgrade procedure ("set -e" mode for script).
- Look at _FFBlog.log, _debug.log and sysinfo.log, ask for help on samygo.tv forum:
  http://forum.samygo.tv/viewtopic.php?f=2&t=1310
- After error reboot TV starts to currently active (februar) firmware. 
- Try use another USB disk, download firmware from another source...

FOR TV repair you need
* ExLink cable: http://wiki.samygo.tv/index.php?title=Enable_Serial_Console_on_non_CI%2B_Devices
* Read carefully wiki articles:
http://wiki.samygo.tv/index.php?title=Recovery_of_Bricked_Device

I think in your case we could just activate alternative (previous good) firmware by changing PartitionSwitch_*_* over console.
I need output from console to commands:

Code: Select all

ls -l /mtd_rwarea/PartitionSwitch*
and

Code: Select all

cat /mtd_rwarea/Version*
and

Code: Select all

df -h
Sure, i need an ExLink output from the start of TV.

Yes, you can revert to previous 3000 firmware. Your TV is CI+ and only one way is left:
ActivateAlternative firmware tool from Content library or script over telnet console.
