JP-8000 EEPROM flash?

Hey,

is there any way to flash the EEPROM on the JP-8000 directly on the chip itself? Anyone tried it before?

(context: I ruined my JP-8k by re-capping the main board, now only the screen turns on, half of the display is full, the other half is empty, no LEDs are working and no sound coming out. It worked before. The connections are ok. The caps are working. No damage on the main board. I believe the OS won’t boot so I’m researching how to flash the ROM.)

Thanks in advance for any help.
