I am creating this thread as suggested by @nkk71
to solve a softbricked HTC ONE. I usually deal with samsung and Sony androids so this is to find community help.
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:
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
I also relocked the boot (as seen in the pic, to hopefully flash a stock RUU
The phone boots
I can also access the OS fully load but reboot just about a second or two on home screen.
