Hi, all.
I've bricked my UE32D5700 RSXZF into eternal bootloop...
TV light up with Smart TV logo... ~15s switch off and re-loop...
1/ I connected VGA SUB-D 25 for serial comm pins: 11=RX , 4=TX , 7=GND and got some kernel's logs but no time doing something between re-loop.
2/ I connected VGA for I2C comm pins: 12=SDA , 15=SCL , 7=GND and got at address 0x50 an EDID eeprom.
- I saw around the SUB MICOM chip WT61p805 could be updated from here ? But don't saw it on this I2C bus.
- May be I'm not on correct pins ?
3/ I connected on mainboard on an another I2C bus and got at address 0x50 a 24c256 eeprom normaly the one messed up.
- There's 5 aligned holes on board: RESET , WP , SCL , SDA , GND near a 8pins chip, near the uP then it should be the 24c256 one.
4/ I flashed the 24c256 with some binaries found around (ex: https://master-tv.com/proshivki/index.php), memory get programed but using a Raspberry Pi it cannot supply +3.3v for all TV logic ! Then I must peek/poke TV switched on... And don't know what really happen.
When I read back da eeprom it looks good but some locations have change. No luck reboot again.
5/ I project to inspect around MICOM but missing some knowledges.
- I'm still trying reverse engenering Postal2 software for protocol and logging LPT port with Wine...
I've dump for WT61p805 firmware extracted from T-MST5-DEUC update but think there's a config eeprom aside MICOM which dump I don't have.
To be sure I need a dump of the 24c256 eeprom for my model cause got one for UE37D5700S, don't know if matter.
Any ideas to Help ?
