Hello all! I haven't been on these forums since the OG Evo days--and a little while over at the Samsung Galaxy S III area too!
I have an issue, unfortunately.
I was given the HTC Evo 4G LTE by a friend to test out (he's a huge HTC fan) to hopefully replace my Samsung Galaxy S III (he doesn't like Sammy at all). I unlocked my bootloader via the HTC Dev site, rooted it (I literally forgot the method I used), installed TWRP recovery, but I still have S-on.
My issue is that regardless of what [correct] rom I flash, I get a bootloop on the loading screen. Example, if I have stock sense installed, it gets to the Sprint logo and then restarts over again.
I was trying to flash the lastest stable release of Cyanogenmod for the LTEvo but to no avail. I read later (probably should've read first) that if I have S-on then I have to flash the kernel separately. I tried flashing the kernel separately and still to no avail. I even tried to flash ViperROM and the Viper IMG Flasher--the rom flashed successfully but the IMG flasher failed every time, yet it still bootloops.
My HBOOT is 2.09, the radio is 1.13.11.0830, and the most recent build I had was 3.17.xxx.x. All I want to do at the moment is return the phone to stock, re-locked (or just locked if that's possible), unrooted working order. I've read all that I can and I still don't know what I'm doing wrong regarding this phone :/.
Thank you guys for your input and help, in advance!
P.S. What does it mean by "This build is for development purposes only do not distribute outside of HTC without HTC's permission" when loading the phone?
