Re: Eeprom dump thread!

25Q40, 25Q80 and 24C512 - they are all on the motherboard, 25Q32 on the panel does not need to be touched.

25Q40, 25Q80 is spi flash, 24C512 is eeprom.

Try all three at once, without soldering there may be errors when reading and writing, just save yours.

Re: Eeprom dump thread!

Replace with a new Spi flash, maybe the problem is not in the firmware.
