Hello there!
The password is not correct. The passwords of the two versions are different. The R1 version is qpmz, and the R2 version is qpmz1234. Since you have not upgraded the transition version, the BOOT mode password algorithm changes. It is wrong to enter two passwords.
You know the original version, you can go back and try it out. If it is not easy to use, you can only go back to the factory for repairs.
