Verizon Note 2 MDM lockout...

So i'm helping a buddy out that was having an issue with several Note 2's that were purchased from a company that restricted their employees access to a lot of things on the phone. My friend handed a couple off to me. The first one was not passcode locked and it was a breeze (Basically just enabled USB Debugging). It is up and running. The other ones are passcode locked and when you try to go into wipe the data/factory reset from recovery it says "MDM does not allow factory reset". The Note 2 I'm having issues with in particular has a locked bootloader on KitKat 4.4.2 through Verizon.

I've spent almost literally every waking moment trying to find a way around this issue. I may have compounded it though. I discovered ODIN, flashed the stock firmware in the hopes that it would clear the phone. It did not (password was still in place). I then decided to flash the stock firmware with the .Pit file for an SCH-I605 and made sure re-partition was checked as well as erase nand. After the process completed successfully and the phone rebooted it will no longer boot beyond the Verizon screen. I still have access to recovery and download mode but in recovery its throwing out a bunch of command lines such as E:failed to mount /data etc. I've tried to reflash the stock firmware with and without the .pit file to no avail.

In the mean time I've tried to unlock the bootloader, attempted auto root, and install custom recoveries to see if I could some how get around the MDM issue. I've also attempted to install or flash from ADB and its still the same deal.

Anyway I'm tired, kind of exhausted, and not really sure what avenues I have left. That's where I'm hoping some of you guys come in. If you have any questions for me let me know and I'll try to shed some more light on it for you. Data DOES NOT matter to me so if you can think of anyway I can get this thing completely wiped out it so I can start from scratch it would be greatly appreciated, Thanks.

Is it just one phone with this problem or several? The mounting issues are becoming more common around here, and seem to be internal memory failure.

Well tonight I'll be getting my hands on a couple other test SCH-i605 phones that are in the same situation (Password locked and no ability to wipe from recovery) and I'll put them through the paces to see if I wind up with the same issue and get back with you on it.

The basic issue with this phone is just after trying that repartition with the pit file it doesn't want to boot beyond the verizon logo anymore and thats when it started throwing those errors in recovery. It could be a coincidence I guess.

I've been messing with Heimdall today to see if I could get a custom recovery flashed that way but the phone fails protocol initialization. The only thing I can get to flash to this phone is 4.4.2 and the i605 pit file through ODIN. Nothing else will budge.

I guess the question I really need answered, is there another way to wipe data/factory reset without the option in the stock Samsung recovery and no access beyond the lock screen?

What I have to work with is ODIN mode and whatever is in recovery that is not wipe data/factory reset.

So I did get my hands on a couple other phones with passcode locks that have the MDM lockout within the stock recovery that still fails to flash anything in Odin except the stock 4.4.2 firmware. So I can eliminate the idea its hardware. I have 4 phones here 3 of which have the same issue and the 4th I was lucky enough to not have a passcode. Quick fix to get MDM removed that way.

Again any ideas that are slightly more outside the box would be appreciated. Thanks.

Edit: If this helps the phone that is working that I manage to clean all of that stuff off of also throws the same error in ODIN with or without USB debugging so it leads me to believe there is something I'm actually missing... Time to go read more.

Yeah I might do that. I'd just hope they have a one size fits all solution because I have about 600 to 1000 phones to tackle... Hahaha.

The conundrum here is that for the MDM company to release the lock on the phone I have to be able to get beyond the lock screen for the phone to process the request. To get beyond the lock screen I need the psswords that the previous company allowed their employees to put on the phones that for some odd reason they didn't have remove.

Anyway if I get this figured out i'll let you guys know how I got it. Thanks for the suggestion.
