[Q] S-OFF'ing the HTC One S4 - Fastboot not working
I need a little help here as I find myself stuck between a lot of possibilities and I don't know which one to take or generally what to do.
My girlfriend has an HTC One S4 with unlocked bootloader (HBOOT 2.15), recovery installed, running Viper ROM 3.1.
However because she only has the 1.15 RADIO on the device it tends to reboot quite a lot and she can't have a phone that reboots that often to use on a daily basis.
I want to S-OFF the device so I can upgrade the RADIO.
I've heard of Moonshine method and rumrunner method, however both of these only work with fastboot drivers installed and working.
This is not the case for her S4. I have a desktop (win 8.1, with USB 2 and USB 3.0) and a laptop (win 8.0 with only USB 3).
And none of them can find the device when it is connected while in fastboot. Therefore I can't S-OFF the device that way..
Could anyone point me in the right direction or have some suggestions on what to do?
