So i send my first RP2 to warranty because my proximity sensor was dead, it went good and Razer sent me a new device with UK branding (Three) after some time of using it I flashed global version, after this on 4G i don't have Internet connection I also can't send or receive any SMS, on 4G+ i need to wait some time to receive or send any SMS but mobile data work perfectly, 3G is working without any problem. I tried to change a SIM card and flash back UK version but problem still remain. I also tried using GSI without any success. Last thing i tried to do was make full backup in QPTS but it stops at 99%. Next i what i did was EFI and Modem backup in TWRP, after this i tried Rog Phone 2 QCN file just to see I can send it to my device via QPST fortunately it worked(of course because it was for Rog phone 2 i had no Imei or signal). After this i restore an TWRP backup with 'success' (Stil RIP 4G). So what i want to do is get QCN file, put my own IMEI and see if 4G is working again.
And of course, sorry for bad English.
