Hi.

thanks for your solution.

i am in trying fix it in last 3 days and i cant.

first i want to be sure that the ROM that i flashed is the correct one.

base on i was received the android 7.0 before and i have XT1572 single SIM, is it possible that the mentioned ROM is incorrect??

i have flashed LineageOS 14.1 but it freeze on logo :( and i can't try it. but i don't guess my problem fix by it at all.

OK now, your solution is that i flash my modem several times after i flashed the stock ROM?? this is mean that i repeat these commands ?? or just the (*) one?

fastboot flash modem NON-HLOS.bin *
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn

edit:

this is my fastboot getvar all if it helps!
