So in the video i will link below you can see what phone is doing. it cant connect to any network. both sim card works perfectly on other phone (iphone 5c, lg g4)
what i tried:
restart phone so many times.
hard reset phone 4-5 times.
remove and then insert sim cards slot.
reset network settings.
insert only one sim for each sims in different slots.
start phone with safe mode, still same.
phone can read imei, tried to call *#06# and got imei 1, imei 2 and serial number.
Dial *#*#4636#*#* and change network type to GSM auto prl (tried other options too), turn radio off and then turn on, restart phone.
change sim1 to 3g, sim2 to 4g or sim1 to 4g, sim2 to 3g.
