In latest sprd phones, in some brands is used protection what use cpu id+ rsa key to protect imei and simlock.
In avenger box this phones usually will give error on unlocking.
To repair imei in this phones need to sign imei(some like this is used in samsung)
Writing nv from other phone will not help, signed imei is unique for each phone.
Good part is, we can upload own rsa key and use it to sign imei.

All this i'am get from disasembling firmware and know teoreticly, and no, it's not supported by avenger this security.

Part what i'am not know yet, how to get cpu id used as part of this security.
Solution can be maked, but need to have 1,2 phones with this security, without phones is not posible to make nothing.
And phones with this security i'am have problem to find.
Here where i'am live, sprd phones in general is very rare.


To identify this phones, make read simlock in diag mode.

If will be 2,3,4,5 security type, is safe to service this phones, this is normal phones and will not be problem.

If phone is locked and security is 0 or 6 or other, this can be problematic phones and need to perform nvram backup(just in case).
