[AT&T, Rogers HTC One X, Telstra One XL] GalaxyWide:
After doing a ton of reading and searching, I still have no idea what my phone is doing. It seems bricked…but only sometimes/partially?

To begin with, I am using ViperXL 3.2.8, elementalX kernel, TWRP 2.5.000 and have been happily using it that way for the summer.

Today I was using facebook to accept a friend request and it suddenly force closed on me. “ oh well” I thought, it’s always been buggy and slow. Hit ok on the msg, then put my phone down. After about a minute, Google play services force closed. Then others began closing, cascading to the point of things like “android core” force closing. My phone then crashed and restarted (its done THAT part before, somewhat often too. Very annoying). I cannot remember exactly, but I think that it then restarted, took foreverrrr to come up, then unlocked the phone and everything started force closing again, faster than I could hit “OK”. Crashed again, restarted…this time got stuck on the Viper boot logo. Let it do that for a while, then restarted by holding power button. Came up, same thing happened. Next I went into TWRP to clear cache and dalvik. When I tried, it fails with the message “cannot mount /cache” about 3 times. Then I went to reboot it, come up and says something like “it doesn’t look like your phone is rooted, would you like to install SuperSU?” whether I click yes or no doesn’t matter, TWRP hangs for a little while and then the phone shuts off.

At this point, I'm mildly panicking, so do some searching. I noticed that “android.process.acore” closed a lot, and it came up that facebook could be an issue. After several tries, got booted up far enough to attempt uninstalling the app. It completed, but the phone then instantly crashed. Checking afterwards, it’s still there. Also, when I do get to into android (about 70% of the time it hangs at the boot animation) and try to access developer tools to enable USB debugging, settings instantly force closes. Same with venom tweaks when I try to change CPU voltage (I'm under-clocked and under-volted, trying to get better battery life..this thing is a total hog for some reason). Oh, and when I get booted up for long enough it’ll come up saying that “internal storage is corrupted and may have to be formatted”.

It gets weirder. Thinking that perhaps TWRP is somehow corrupted, I attempted to flash a different version (2.6 first, then 2.3.3.1). “fastboot flash recovery TWRP.img” completes just fine, no errors. But when I go to recovery, 2.5.0.0 is still there! How it that possible? Also, “fastboot erase cache” completes fine too, regardless of what TWRP says. But I'm not convinced it’s doing anything at this point. Another odd thing, the phone will not successfully reboot with either “fastboot reboot-recovery” or selecting it in the bootloader menu. It shuts off, then the charge light comes on (to indicate booting) but then goes off again before anything comes on screen.

One more thing: when I tried "fastboot oem lock" it fails with "status read failed (too many links)".

I apologize if this is disjointed, I’ve tried a lot of things in a short time and they kind blend together a little.

TL;DR:

Every process on the phone force closes on boot

TWRP cannot mount /cache

TWRP cannot be updated, even though fastboot succeeds

My phone is posessed!

HELP!

Thanks in advance, at this point I'm ready to try anything, if only to get it so I can give it to AT&T and get a different one!
