Phone have erased sml sign, signed with vendor rsa key.
If you not have original nvram backup for this phone, is not posible to repair imei or simlock.
You can't restore sml sign from other phone, each phone have uniqiue value.
In new sprd(unisoc) phones need always to make nv backup before rewriting nvram or play with firmware.
Avenger box always will preserve sml sign in this phones, and will make backup.
In case of other tools, no idea, if you can't restore original nv, for now is not posible to repair this phone.
