Please help me. Xiaomi mi4 lte I lost the signal after upgrading MIUI 10, even though the sim card is ready and the IMEI is still there and Baseband is still there. I have written QCN in MIUI 10,9,8,7 global versions and Downgrade from MIUI 10 to 8,9,7 and write qcn but there are no results yet the network has not appeared and I have done a Restore QCN in QPST there are still no results . Are there other solutions? It would be very helpful if someone provided a solution. Thank you
