hello,
IPHONE 7 Audio IC repair was FAILED and PHONE STUCK AT 'SEARCHING' error WITH NO IMEI.

Baseband REBALL was performed and phone SHOWING

'TRIANGLE WITH NO SERVICE'

REBALLED BASEBAND IC AND STILL SAME PROBLEM

L5803_RF AND L5802_RF HAVE NO VOLTAGE, OR HAVE ZERO VOLTAGE.

ALL OTHER VOLTAGE ARE OK AND GOOD FROM BASEBAND PMU TO BASEBAND CPU.

I have checked all voltages AND ALL OTHER VOLTAGES ARE GOOD ONLY L5802_RF AND L5803_RF are missing

how to fix OR BASEBAND is DEAD?????

iPhone 7 No Service is mainly caused by two reasons. The baseband PMU has been pseudo soldered. Or, the baseband CPU has shorted. It can locate the faulty component quickly through confirm the version of the logic board.
