Need help here! I forgot to backup my oneplus 9 pro LE2127 when I tried to root my phone using TWRP,and I installed TWRP in my phone's boot partition which wiped out all data in that partition. I used TWRP side loaded Global ROM to recover my phone but the phone doesn't have any signal with sim card in. Used MSM tool backe to T-Mobile 11.2.5.5 and still same problem, sim card can be read but no signal. Flashed T-Mobile modem but modem b failed, it says no such partition.
Bought this phone from third party. Any suggestion is appreciated.
