Issue, I have recently received an HTC ONE which has been rooted, TWRP installed and was S-ON. The baseband was lost, with 4.4.2 verizone version flashed.
Here are the details:
version-misc: PVT SHIP S-ON
serialno: HT36xxxxxxxxxxx <----removed
imei: 35xxxxxxxxxxxxx < ---removed
Some initial remarks from @nkk71 :
1- radio is a CDMA version (from the looks of it)
2- version-main is missing
3- the device is now S-ON, very likely it was S-OFF at one point, and s(he) went S-On because of panic (which was probably the worst idea ever)
I did re-flash CWM touch and also flashed a CWM flashable stock ROM
The phone boots
I can also access the OS fully load but reboot just about a second or two on home screen.
