It was a dying bison purchased on 11/2020, worked normally for 8 months and then blocked it. I had to flesh the phone and put firmware ver 20210405.
After that, the phone works, but he won't make phone calls, carry it to the master and say I erased the IMEI numbers. So I have a question?
They gave those numbers somewhere physically written and from whom and how they can get them because, as the master says, they determine frequencies 3G and 4G, and that's why they can't work!
How do I solve the problem? |
