I know, never update firmware, but....
Sorry for my english...
Before the upgrade, I root the tv with samygo, downgraded firmware from 2022 to 1012, I played with ssh and some xml config through ftp, but I needed to use plex client, and without firmware update, not work. For this reason, I downloaded the version 2003 (I'm not sure), put the pendrive, start upgrade... and now... tv start, but after 10 sec, I can't do nothing... remote not work, manual controller on backside not work, no shutdown possible. If I start in Service Menu, I arrive at "reset" button, but I can't do nothing... tv stop working.
Th tv is briked? Reset eeprom will help?
Wht I can do?
After one reboot, I've look on service menu, and seems something was changed, because now I see OTN support set ON, before was disabled by me. This means the reset was done?
Tomorrow or asap, I will try to do the reset of EEPROM, but, I want ask to you, I need to take some photo of service menu conf before the reset? Or identify the panel model is sufficent?
Otherwise yeah, you'd need Front Color and Panel values, but first try the correct reset
Ok, now I do the correct reset and now tv live again. Many many thanks!
