You also asked for 24С512, maybe eMMC is covered with you (they have a certain service life).

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.

Re: Eeprom dump thread!

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

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