I humbly approach you today with a HTC One issue, that needs solving as I have no phone as a result.
So to put it simply I Unlocked and Rooted my device through this guide .
Following that I proceeded to gain S-OFF, or at least I believe I did. Checked the Bootloader after and it said S-ON :S Through this guide.
All seemed well up to this point, so then I followed to this guide to install 4.4 KitKat on my HTC One (I am based in the UK, and the network my phone runs in is O2).
However as it turns out, my phone will now turn on, I will reach the default Android Language Selection menu, and my phone reboots automatically before I can even press anything. I have tried to re-install the "bigxie_Reset_M7_3.62.401.1.zip" several times, and nothing has come from it.
So I attempted to restore my stock HTC rom, using the "RUU_M7_UL_JB_50_HTC_Europe_1.28.401.7_Radio_A4.13 .3231.27_10.31.11131.05_release_310878_signed.exe" and it fails every time, and it also detects no image when I run it, it simply shows what image it will install.
Additionally I tried all possible USB ports on my computer to check for a faulty USB port with RUU, I have tried to push "Guru_Reset_M7_3.62.401.1.zip" through CMD (I am running windows of course) and naturally it hasn't worked (the push). Having not made a Backup because I blindly followed the tutorials, I have nothing to go back to.
I think the problem is that S-ON is enabled and I can't seem to find how to solve it, or enable S-OFF using the AIO Toolkit and pushing Revone. Anything that could help me get my phone working, and hopefully with stock Android will be greatly valued. Thank you for taking the time to read this .
