Hi friends!! How are you!? �� To day i change the tristar on 6s whit battery drain problem. Remove the old tristar cleaning bga on the board and solder new tristar. The phone power on! No hot and no battery drain! Except I don’have signal anymore. The message says: Upgrade the phone! The wifi work, the bluetooth work, the front camera back camera and flash work, vibradash work, audio speaker work! Everything works except the network. If I type *#06# imei does not appear. In the general settings, about appear imei. Not appear modem firmware. Can you give me a hand? What could be the problem? Thank you friends!
