Service Provider in settings keeps appearing and dissapearing
This phone has been previously liquid damaged and cleaned very well on the logic board.
Now the leftover issue is:
Service Provider option in settings keeps appearing and dissapearing, phone sim card detect fine, goes searching then no service.
IMEI and modem firmware displayed in settings, checked *#06* no problem there too.
Is it okay to reflow the U_WTR_RF transceiver chip because of liquid damage before? Maybe it'll fix the problem?
