[One (M7) Q&A, Help & Troubleshooting] The Lich:
First things first, I'm not a noob. I'm just new to actually registering in these forums. I've already learned my way around most thing here (and solved my other problems) just from anonymously browsing. In fact, the fact that I'm even posting is kind of a sign of defeat, you know?

Ok, so my phone randomly stopped being able to get cell service the other day while I was at work. When I got home, I re-flashed the latest CyanogenMod ROM, but that didn't help at all. Now I can't seem to get ANYTHING to mount my /data partition. As of right now, here's a list of everything I've tried that didn't work:

- Reflashing CyanogenMod

This just didn't change anything. Meh.

- Flashing the stock ROM

I was unable to get fastboot to work with me very nicely. I re-locked the bootloader successfully, though in trying to flash the ROM in RUU mode, I get this error message:

sending 'zip' (1118196 KB)... ERROR: usb_write failed with status e00002be
FAILED (data transfer failure (No such file or directory))

The command "fastboot getvar all" (not in RUU mode) yields this:

INFOversion: 0.5
INFOversion-bootloader: 1.44.0000
INFOversion-baseband: 4A.17.3250.20
INFOversion-cpld: None

INFObuild-mode: SHIP
INFOboot-mode: FASTBOOT
ERROR: usb_read failed with status e00002e8
getvar:all FAILED (status read failed (No such file or directory))

Which would lead me to believe that I may have just wiped an important partition, though I don't know how.

I know I flushed the cache with fastboot, but that's just the cache.

- Restoring from a TWRP Nandroid backup I found around the forums

Up until this incident, I've been using CWM Touch. I didn't have any issues flashing TWRP's recovery a second ago, though it can't mount anything either. Not only that, here's the kicker: I can move around / but I can't seem to delve any deeper into the filesystem whatsoever. I used ADB to move my Nandroid zip over to like 3 different folders, but that didn't work.

It may be worth noting that I've been re-flashing to CWM in order to use ADB, then switching to TWRP to install the Nandroid backup. I couldn't get it to detect my phone when running TWRP. That shouldn't affect anything though, right?

- Factory Reset

You read that right. Factory resets in TWRP fail. Yeah... it's like that.

Any comment/suggestions are welcome. I can't think of anything else I haven't tried, which means that it's probably super obvious.

For the record, I'm running OS X 10.8.5 on a MacBook Pro. As a developer, I have access to multiple VMs if moving to Windows (or even Linux haha) would help. Also, yes, I've edited my $PATH in bash, so directories and fastboot/adb's places on my HDD aren't an issue.

I haven't used any of those b.s. toolkit things because they're all written in .NET. I mean, come on. .NET? No, thanks hahaha

(that's totally a joke, don't anyone go taking offense)

...on a semi-related note, is there even any demand for a toolkit that would run on Unix-based systems? I'm sure I could make that happen.
