The problem arose when the printer didn't boot as expected the leds remained blinking instead of remaining solid, after a quick look on the user manual 5B00 error was the responsible. So after booting the printer on service mode and tried to factory reset it, but it just got bricked. In order to unbrick the printer, it is necessary to flash the eeprom with clean images.
This board has 2 eeprom, one on each side. A GigaDevice 25Q16BV and a Micron 25Q064A, both of them need to be flashed in order to fix the printer.
