For example, I see that I dont know the different between the eeprom and pic file.
They are different according to the Zeusbtc below the hashboard has a PIC chip and EEPROM chip so maybe yes you need to restore a pic file but the problem is do you have a working pic file? ZeusBTC is selling pic files in a package, not by piece.
However, I don't think the issue is the pic firmware the error is pointing to EEPROM so maybe the file you read from another hashboard might also have corrupted EEPROM you need to find a known working hashboard to read the EEPROM and flash it to these hashboard.
