RUU appears to work, but stuck on bootscreen logo
I also installed the OTA update, which did eventually get to 4.2.2, but after a few days went into bootloop. I applied the RUU with no luck. It appears to work, but then reboots to the htc screen and hangs.
I've also unlocked, installed custom recoveries. TWRP or CWM no touch for the HTC One X+ At&t. both report errors of unable to mount /anything. TWRP refuses to sideload or install a ROM after adb push (which I can get to work sometimes). CWM will install from sideload, but ROM install (Elegancia 6.2) stops at 13.07% and hangs.
I have tried all of the steps from multiple posts in these forums and what works for others seems never to work for my phone. What could the problem be? Permanently unable to see the partitions? Something corrupt in hboot 1.73? Since I can't access the phone to change the USB debugging setting (not sure if it was checked or not) and I can't change the fastboot mode in settings (last set to fastboot enabled), perhaps trying a factory reset caused the problem (one thread mentioned factory reset won't work if the settings say fastboot within the phone).
No clue, so any insight would be helpful. At this point, after weeks of trying to fix this phone, I'm nearly ready to give up. I'm stubborn, but now I suspect there's an unsolvable problem that I just don't have the expertise to see.
