I have this Oppo A91 phone, null IMEI. The phone has Helio P70 MT6771V CPU. Android 9.
However,  Modem Meta failed with the error "Write IMEI to target failed" at the write IMEI step. 
I also rooted the phone and tried all the methods listed here (https://www.hovatek.com/forum/thread-116.html) but none worked. I haven't tried recent Box versions though because I cannot find any loader that works.
Does anyone know if there is a way to fix this "Write IMEI to target failed" error? or any other methods to restore IMEI?
Also, from how the z3x pandora and other paid Box methods work, I figure out that there is a need to patch certificate to get the new IMEI to work. Unfortunately, I cannot find  any information regarding this patch certificate.
