PS5 Disc -> Digital BIOS SU-101217-2 Error Code

My PS5 originally wouldn’t go into Safe Mode and only showed a blinking blue light. I suspected the disc drive, so I swapped in a known-good one while keeping the original daughterboard, but updates still failed. I then pulled the BIOS chip, read it, converted it to a Digital Edition BIOS, and flashed it back. After that, the system would go into Safe Mode, but it stopped detecting Wi-Fi networks. I repeated the process and even tried another BIOS chip from a disc console converted to digital, but nothing changed.

The update fails instantly with error SU-101217-2. Online, I’ve seen guesses ranging from SSD issues to a bad Wi-Fi IC to the southbridge needing a reball. Since the southbridge is right next to the BIOS chip, I wondered if I might have affected it during the work. Under a microscope I didn’t see obvious damage, but I tried a reflow anyway since I don’t have reballing experience. After the reflow, the console didn’t automatically enter Safe Mode (could just be because I had reset the database beforehand), but the symptoms stayed the same: no Wi-Fi networks at all, LAN works fine, Bluetooth works, and updates still fail instantly.

I tried restoring the original BIOS, but I lost the small 4.7k resistor under the BIOS chip during rework, so I couldn’t test the original firmware. At this point Safe Mode only works when selected, Wi-Fi is completely dead, LAN and Bluetooth work, and the system still throws SU-101217-2 immediately. If anyone has run into this exact combo or has advice on what to check next, I’d appreciate it.

Hi!

Could be a lot of things. Since your wifi completely stopped working, I would first check that IC out.

I would first solder a new resistor in and maybe then try a new wifi chip And see what happens.

The update error could be caused by the southbridge or any other component.

I would start with the Wifi IC first.

Please let us know how it Goes!

So I think it had to do with the actual bios file. I used a different digital bios file adjusted the SN, and then I rebuilt the database cleared the cache and reset the storage. And I was able to update the console and it seems to have resolved the WiFi issue

Ahh.. then it is something in the firmware. Glad that you were able to fix it! Did you replaced the flash chip?
