Need Help Converting Boox P6Pro(Chinese version) firmware to Boox Palma 2 Pro(Global)

[giamre]

Hey guys! During my trip to China, I bought a Boox P6 Pro, which seemed to be exactly the same device as the Palma 2 Pro (but with a different name, as is often the case).
In fact, in terms of hardware, it seems to be the same thing, but on the software side, even though I managed to install the Play Store on it, it has several issues and often displays messages in Chinese.
Now I’d like to know if anyone has managed to—or can help me— convert to an international version.
I’m pretty comfortable working with ADB, the terminal, Android, etc.
Can anyone help me?
I’m attaching the libota_jni.so

Thank you

Thanks for the file.
I did find an update.upx for this model.

Model:  P6Pro (Chinese)
Finger: Onyx/P6Pro/P6Pro:11/2026-05-09_16-00_4.2-rel_05092_49329622e/8608:user/release-keys
Link:   http://firmware.boox.com/6958961c8549ece5b56d0845e6f2cc9c/update.upx
Size:   1,966,166,797
MD5:    6958961c8549ece5b56d0845e6f2cc9c

But something is screwy, I can't seem to decrypt this one.
Maybe they have the wrong link?

If you're not up to this version you can try updating.
If the link is wrong it won't do any harm.

I can't decrypt this file either.
When I try to install it as a regular “manual” update on the device, the decryption is successful, but it appears the message: “The update package is not compatible with this model”.

I did a quick check to see if I could decrypt it as another model.
I tried 100+ and no dice.

There is two model of P6pro: P6pro bw and p6pro color. The equivalent of Palma2pro is p6Pro Color, both have color screen. I can find two firmware for P6pro and P6ProC
P6ProC:

http://firmware.boox.com/717ae3b19263f00f336b7161370c0fd3/update.upx
MD5: 717ae3b19263f00f336b7161370c0fd3

P6Pro:

http://firmware.boox.com/6958961c8549ece5b56d0845e6f2cc9c/update.upx
MD5: 6958961c8549ece5b56d0845e6f2cc9c

Any chances OP's device is P6Pro Color and the firmware you are trying to decrypt is P6Pro BW's firmware, so u cant decrypt it?

Can you confirm yours is a BW or a Color version of P6pro?

Yes, I can confirm that the libota that was posted is for the P6ProC.
If someone has the one for the B/W P6Pro it would be appreciated.
The key file has been updated.
