    I strapped a metal bar to the motherboard, forcibly flattening the bent board. ‌I strapped two metal bars to the motherboard, forcibly flattening the bent board, then soldered the APU.

    Since it's a ‌dropped PS5‌, this most likely caused ‌cold solder joints on the APU‌. You can check the ‌resistance values of the capacitors on the back of the APU‌ — there are about ‌10 power supply rails for the APU‌.

    Latest update:‌ By reinstalling the APU with ‌reballed solder balls‌, I seem to have ‌resolved the freezing and shutdown issues‌. However, before this, I ‌failed three consecutive times‌ to reinstall the APU because the ‌warped motherboard caused...

    ‌I reinstalled the APU on a PS5 that was booting normally, but now the blue light keeps flashing — all chips are heating up normally, yet there's no display output. I think this is related to the soldering — the motherboard warped slightly after...

    CZFX replied to the thread Ps5 C00C00303 Uart code.
    C00C00303 refers to VRM Controller Access Error.If the APU is not powered, you need to check the XDPE chip and its related circuits.

    Perhaps it could be a RAM failure? Sometimes, damaged RAM doesn't cause abnormal heat or error codes, but can halt the boot process due to memory data corruption.

    ‌I saw your suggestion earlier, so I replaced the XDPE at the very beginning, but it didn't improve anything.I checked and confirmed that the XDPE is working perfectly fine.

    ‌‌Latest update,I found that Error Code: 80830018 = SoC Sync Flood, and similar errors also occur on AMD platform computers. I think this may be caused by an APU defect — the APU cannot operate stably at the maximum frequency, but it works...

    In my case, I don't think the Southbridge is the culprit. PS4 games work fine, but PS5 games don't — that's the thing. I've read that the APU runs at lower clocks for PS4 games, while PS5 games push it to higher frequencies by default. Most...

    I also have an EDM-030 with this problem.. It works perfectly fine when I launch music or video apps, but as soon as I run a game,the screen freezes within a few minutes, and then it shuts down a few seconds later. When the fault occurs, I get...
