I had to ditch Verizon. I didn't want to fork over $300 for a Republic Wireless phone only to be stuck with their crappy ROM, and the only 4G LTE android phone supported by Ting is the Evo 4G LTE; picked one up for $50 on ebay. I installed Cyanogenmod on a half dozen devices, newer and older than this phone, and thought this HTC Evo 4G LTE would be as easy as they were to unlock, root, S-OFF and flash. I've been more wrong before, but not without resulting in bodily harm. A hearty 'get stuffed' to HTC for this, and a plea for future rooters to have a concise guide on how to repair their phone under these circumstances.
The flawed process...
I went through HTC's unlock method to unlock the phone. Then I installed the latest TWRP via fastboot command line (126.96.36.199b as I found in a thread somewhere). No problems so far... I then went to install the latest CM build for Jewel (10.2.0 ) through TWRP 188.8.131.52b and it failed. This marked the first time I'd ever seen a fail message in TWRP. I thought no big deal, I'll restore the backup... The backup was gone. Now we have problems; phone is stuck in a bootloop. After reading many threads stating that S-OFF is required to flash their ROM, I tried to achieve that in Windows 7 to no avail through all available means. I then tried the closest RUU for my phone, and it failed. I then tried every RUU I could find, all failed. I tried a full firmware update to 4.13 via PJ75IMG.zip on the SD card, which failed.
The repair process that worked for my situation...
Once I focused on the HBOOT as a potential issue, I found this thread: http://forum.xda-developers.com/show...9#post40848479
Quite simply, MeanBean 3.09 worked as advertised, and my phone has booted into a ROM for the first time in days! A HUGE thanks to both Magnum_Enforcer and mikeyxda.
