[Sprint Samsung Galaxy S III] dwnocturnal:
Let me first apologize for all of the information, but I wanted to give you guys as much to go on as possible.

TLDWR - Can't flash roms, can't decrypt phone, can't wipe data, can't mount internal storage, can't use ODIN....where next?

Here is what I got:

SPH-L710

Android vers - 4.2.2

Cyanogenmod vers - 10.1.0-d2spr

Was getting flaky reception when I was on 10.0.0 nightly, decided to update to 10.1.2. Downloaded the the required files through Rom Manager, rebooted into CWM Recovery version 6.0.3.1 (non-touch) and did the install (dirty)....booted up and the ROM itself worked, but all my apps were getting "stopped unexpectedly". I figured, ok, did a dirty update so stuff isn't working; I'll redo it and this time wipe everything (after backup of course). When I went to do this, I noticed that it did not mount my sdcard (internal storage, not external sd card). I thought was odd, tried manually mounting, didn't work, tried rebooting recovery and that didn't work. Thought maybe it was a fluke, tried wiping and reflashing 4.2.2 (CM 10.1.2).....it went very quickly. Rebooted, and all of my stuff is gone, which is good, but now it won't let me restore apps.

At this point, I decided I'd had enough of trying to upgrade, so I decided to downgrade back to my old CM 10.0.0....long story short, the flash went quickly, booted up, things worked, but still had the same problem with the apps. I could see the data on the internal storage when the phone was booted, but it never saw it in recovery mode. After doing some reading, I saw where the filesystem changed when going to 4.2.2 so that you can use the new profiles feature. This seems to be what caused CWM Recovery to not see my internal storage anymore.

I thought well, maybe it's because I am back on 10.0.0, so I tried downloading and flashing 10.1.0. It did the same quick flash and showed after boot that I was running on 10.1.0, but I still couldn't mount internal storage (sdcard) in Recovery. I said screw it, reinstalled my apps and decided to truck on with how it was. Short version here - installed mobileiron and touchdown, ran through the encryption in mobileiron, etc etc...mobileiron didn't recognize touchdown and I could not get LEAP for wifi to work.

Decided I would try to decrypt and completely wipe phone. Removed Mobileiron as administrator, tried to decrypt - could not. Tried tweaking security settings, reboots, adb mount and format - all to no avail. Tried wiping in recovery....this failed because it cannot read my storage (because it can't mount it and it is now encrypted)!

With the phone booted up and running adb shell, I can get to the main file system, but my sdcard, data, data/media directories all look empty. I can't mount sdcard through ADB either.

When all of this failed, I looked to ODIN to fix my woes...no luck here either. Downloaded the stock Sprint ROM (4.1.1	L710VPBLJ7	L710SPRBLJ7 ) and tried flashing it but I get hung up on the "Setup Connection"...in ODIN. I have tried multiple drivers, usb ports, battery pulls, etc...I even tried from another PC.

I know this is a lot of information and I apologize again. If you read through all that, thanks for being thorough...if not, I will answer your questions, but hopefully won't have to repeat a bunch of info again.

My end all questions are - where do I go from here? What other options do I have? Is there any repair place I might be able to take this to that they might be able to decrypt/flash the phone to stock for me?

Thanks in advance,
