So first sorry for my bad English but Iím from Germany And also Iím a total amateur with Android and roots and all that stuff.
Now back 2 topic.
So I bought my HTC One (M7) almost a year ago. I rooted it, unlocked it and also got S-Off. Yesterday I tried to get it back to stock so I could finally get some OTA-Updates. When I first entered the bootloader (if thatís the name of the white screen) everything seemed normal. But after I left my One got stuck in a Bootloop. I thing I know the cause for that but I will come back to that later.
My big problem is that while Iím in the bootloader my PC cant connect with the One. The device-manager says something like ďcant start the device (code 10)Ē. So I cant use RUUs and the likes to get it back to stock. I tried all kinds of drivers and all USB-Slots I got. Nothings changes.
Another problem is, that my Phone is back to S-On, though I have no clue what I could have done to do that. And that brings me back to the Bootloop. After I wiped all my Data I could start my phone and had no Bootloop, everything worked just fine (though no APPs where left of course). But I got the message I should Install SuperSU. The second I did that I was back in the loop. So I think S-On and SuperSU is not a good combination. But since I cant connect the One via Fastboot I also have no clue how to S-Off it again.
If I just could connect the Phone with my PC via fastboot I would probably be able to get stock back. Does anyone know what the problem might be?
I donít know if it helps but the bootloader says:
M7_UL PVT SHIP S-ON RH
And I also use Windows 8.1
