[App] ForceFirmware Back (FFB)

[juusso]

Have you tried the FFB once again? Remove logs and run. If you have exlink, save debug log to file.
If you dont get success, here is a way to flash firmware directly over telnet.

More detail inspecting of logs showed, that firmware is not flashed to TV. I don`t know why. Try again and if no success, then only manual way left for you. Look at the times of start and end of procedures:

Code: Select all

[00:01:54] exe.img.enc copied to /mtd_swu/ successfully!
Start flashing to /dev/bml0/10
[00:01:54] /dev/bml0/10 restored. Deleting source...

Code: Select all

[00:01:58] appdata.img.enc copied to /mtd_swu/ successfully!
Start flashing to /dev/bml0/11
[00:01:58] /dev/bml0/11 restored. Deleting source...

i will think about the issue. It could be also NAND defect too, i saw one TV with such problem. I would like to inspect your TV over TeamViewer (and probably to flash the preFEB firmware manually for you)

p.s. I just re-flashed my B653 with FFB0.6.2.1 and everything went fine:

Code: Select all

Welcome to pre-FEB world !!!
 
TV is rebooting right now. Bye :)

p.s. problem solved.

[juusso]

Yes, sure. But you have to use RSA dissabler first.
(we`re talking about ci+ model, right? I guess T-CHUCIPDEUC)

[juusso]

Hi. Thanks for reporting!
I think you should use the FFB version 0.5.9. It worked well for CI models.
Here is the link.

[juusso]

Attention!
Temporary CI users please use FFB 0.5.9 version. The latest version works on CI+ devices only. To be fixed soon.

[juusso]

Hi,

Get SamyGO Dump maker, make dumps of existing firmware, archive and upload to multiupload.com.
I`ll inspect and tell you what is on board...
