Fixed a Purple Screen of (Death)
Yesterday I got a persistent Purple Screen on my Switch, turns out it is a rare error, for which I couldn't find a solution online.
It couldn't load anything but the SX OS menu. Thought it was bricked.
The quick answer is: I fixed it by running SX Menu's inbuilt GPT Repair mode.
So if you're using SX, try that first.
What I did before it happened:
Made a NAND backup using SX 2.0 Menu on my 5.0.X Switch.
I only backed up Boot01, Boot02 and SYS.
It finished, then the SX menu crashed.
Waited for 2 minutes, did a hard power-off.
Turned back on my switch holding Vol+.
Entered the SX menu and tried to run Custom FW.
Then a Purple Screen.
Hard power-off.
Back in the SX menu, I tried running Original FW.
Purple Screen.
Luckily I could enter the SX menu everytime after I turned the Switch off, so I tried several different settings;
uninstalled and installed Auto-RCM, booting without SD Card, booting without dongle, etcetera.
Noting worked. Everytime I tried to boot either Firmware I got the Purple Screen.
Then I copied the backed up NAND I made earlier to my PC. Turns out the SD card had faulty sectors.
Tried restoring my NAND using a clean SD Card in SX menu; Boot01 and Boot02 succeeded. SYSnand "failed=(some memory location error)"
Used A different, newly formatted SD card, same error; SYSnand restore failed.
I was out of options, and just tried using the inbuilt GPT repair mode in SX Menu 2.0
It did the job. Fast and easy.
My Switch loaded both Original and Custom FW without any problems.
Also I didn't loose any data at all.
Hope this helps for people encountering a Purple Screen of (not really Death).
