Sorry. It's doing the same thing again.
You can try to see if you can install the same Chinese software as a test.
Code:
Model: Leaf2_P (Chinese)
Finger: Onyx/Leaf2_P/Leaf2_P:11/2024-09-11_18-02_3.5.4_d62d1a782/9421:user/release-keys
Link: http://firmware.boox.com/7cb44c69deb791b32224b369e9655981/update.upx
Size: 1,702,361,713
MD5: 7cb44c69deb791b32224b369e9655981
If it succeeds you will have to reflash the custom recovery.
