[UE40D5700] Serial Console cannot be unlocked

Post by saiterio »

Hello,
.
I'm trying to unbrick my samsung TV UE40D5700. This one is bricked since a firmware upgrade. The behaviour is that my TV reboot systematically just after the Smart TV screen appears.
I tried to follow the numerous discussions/tutorials I found over the SamyGo website and the web but I didn't succeed to unbrick it.

Currently, I'm trying to unlock my serial console with the code for my TV (1198282), but console is still locked.
Here is the logs of the console:

Code: Select all

Do you have any idea? My TV is definitely bricked?

OK, I didn't close this subject, but I found the way to get uboot prompt with serial console: use ~ key!
