Can't update to Android 14, even on stock firmware

@PlatinumLucario

flash the stock partitions via adb and fastboot that I had backed up from earlier

What exactly have you done? Only the boot.img or anything else?

How did you install TWRP and what have you done to remove it, because I understand you are back on AOSP recovery?

When you follow my link above further to the FP4 topic, I guess what you would need(ed) is a clean vanilla status

FP4 Root Access is possible, maybe a bit risky

So you downloaded version FP4.SP21.B.048 from here, right?! Those are outdated, the current FPOS version is FP4.SP25.B.058, which we don’t have factory images for yet. For future reference, no matter what people tell you, don’t flash it (if you don’t have a good reason to), that only creates problems, and you loose the ability to restore the stock images through the Magisk app before an OTA update. That recovery doesn’t seem right, I would expect 12/SKQ1.220201.001/SP25 if you are on the l…

however I’m not sure which role TWRP might add, as normally you only boot into TWRP (never flash it) and I dont know what a permanent install would change.

When you say

@PlatinumLucario

backed up from earlier

Which OS Version, i.e. any older Version than latest A13 (guessing you had the latest A13 installed,that should habe been FP5.TT4H.A.162.20240609?
