Solution
This issue is related to the NOR (BIOS) IC.
The first thing we can try is using UART, send the command "errlog clear" to clear the error code database.
Follow this guide on how to connect to UART PlayStation 5 Fault Finding Using UART ,then in console service tool, in select operation type select clear error codes.
Why this works? Because sometimes the DBI section of the NOR gets full.
If the first option doesn't work we will need to remove the BIOS IC from the motherboard and using a donor BIOS file.
The BIOS chip (25Q16JVNIM) is located next to the southbridge.
Step 1: Remove the BIOS Chip
- Locate the BIOS chip (25Q16JVNIM) next to the southbridge on the PS5 motherboard. Use a hot air station to carefully desolder the chip. Exercise caution and avoid excessive heat, as it can damage the chip.
Step 2: Connect and Read the BIOS Chip
- Solder the bios chip to the SOP8 adapter.
- Connect the chip to the programmer.
- Connect your programmer to the computer.
- Read the chip and save a copy of the bios file on your computer it will create a .bin file.
Step 3: Fixing your BIOS Dump
Using a free tool made by Dony this process is really simple, download PS5 NOR EDITOR
After downloading the tool, open it and click on pre-configured and select your board type.
After that, click on the browse button on the harvest section and find your dump a small pop-up window will show up and ask you what options you want to harvest, select all options and click on OK.
After that, save your file.
Step 4: Write the Modified BIOS File
Load the modified BIOS file into the programmer software. Write the new BIOS data to the chip using the EEPROM Reader/Writer.
Step 5: Reattach the BIOS Chipeditedit source
Solder the BIOS chip back to the motherboard, ensuring it is in the same orientation as before. Reassemble the console. You may leave the disc drive disconnected if desired.
Final Testing
