Today, after a week of torment, the following helped me: Z deleted the nv_data.bin.md5 and nv_data.bin files. The nv_data.bac.md5 files were renamed nv_data.bin.md5 and nv_data.bac in nv_data. bin.The phone didn't restart.Turned on and turned off airplane mode. And the network appeared and the data transfer icon appeared. Imei Status

K
Didn't work for me. I renamed the backup files and each time the md5 file gives different values when I turn airplane mode on and off. Imei is still NG. This is NV log if someone can make sense of it and help:
