Then you should proceed cautiously.
Incremental updates are fraught with danger and it's amazing that they ever work at all.
I recommend only doing incremental updates from a stock system using the in-system update procedure.
That is, parking a downloaded update.
upx in /sdcard and kicking it.
Were you using:
Code:
Model: NoteAir2 (English)
Finger: Onyx/NoteAir2/NoteAir2:11/2025-04-01_18-03_v4.0-rel_6d15a71551/49339:user/release-keys
Link: http://firmware-us.boox.com/9bcffd5069a01c2f90b90a778e27b376/update.upx
Size: 1,842,921,370
MD5: 9bcffd5069a01c2f90b90a778e27b376
I would suggest trying my custom recovery and installing that again.
