[AT&T Samsung Galaxy Note II] Desperate for help:
Hello XDA forum patrons, if I am out of terms for stating that I will pay for help, I apologize as I am just that desperate for concrete help and or affirmation of being screwed. I am not a new person to this forum but I made this account specifically for this problem. If I have offended anyone to this point I apologize. So if I am allowed to offer monetized reward for real results then please allow me to continue and hear my plight.

I have an AT&T Galaxy Note 2 Model - SGH-i317, while I have successfully and easily rooted and flashed custom roms for over 10 different phones, this one has ultimately made me a fool either in personal error or erroneous rom damage. So in that allow me to explain what I have done and maybe, hopefully, someone reading this can help me get my phone in a usable state as the stress of my girlfriend ( it's her phone ) is slowly killing me and this is consuming every waking hour trying to fix. #firstworldproblems

I digress.. lets jump in.

5 Days ago after realizing that the new rolled out 4.4.2 update disabled tethering and hotspot creation from 3rd party apps such as Foxfi, ( i live in an area where the only options for internet is cellular, dial-up, satellite) I became enraged and decided to root and install a rom for it so I could bypass and circumvent what I felt was crap, and or my impatience to wait for FoxFi to be updated to bypass these changes. So I backed up my rom, installed CWM and supersu 2.1 with no problems, I then installed LiquidSmooth Rom 4.4.4. with no problems everything worked fine, well almost. Silly me I had forgotten to take in account that LiquidSmooth was a very fast, clean android experience without any hint of touchwiz and pen usage.. well I hadn't really cared nor wanted those features but my girlfriend damn sure did. "How am I to take quick pen notes now?

etc... so I decided to switch to DN3 V5.2, well CWM wouldn't allow me to install so I tried Philz to no avail, so I installed TWRP and sure enough it flashed and installed fine. Well there was the problem (at least I am guessing) as DN3 V5.2 is based on 4.4.2, so as much I know with roms is you can go up but never go back... if I am wrong please correct me, So after booting up, my sim card was not being read, so I was like WTF? Turns out I installed the rom for n7100, instead of for n7105/sgh-i317... doh, so I thought well that's no big deal, I will just go ahead and flash the correct one, well I did same problem... so then I got panicked and plugged my phone up to my computer, my internal storage was cleaned out, my titanium backup folder with all my progs and other useful things was removed.. so yah, I think my .efs got wiped. I have never up till this point had this type of problem so never have backed up an efs exclusively, I have always made rom backups but never efs. I guess that is my folly as well, so here is my question am I borked or does someone know what to do here?

Things I have tried:

1.wipe/format/dalvik try to reinstall Liquid smooth to no avail TWRP says failed.

2. Restore rom, TWRP doesn't find the file, I guess it doesn't recognize backups from CWM? that are not made in TWRP? so tried Philz, Philz says "Error while restoring /system!", so I reinstalled CWM and CWM installed it, however after getting to the AT&T splash logo the phone stays there in bootloop.

3. tried different things utilizing steps 1 and 2 with liquid smooth

3. From there reinstalled DN3 5.2 successfully, still no service or data.. and that is the last step I have taken.

My questions are as follows:

1. Does a back up typically save .efs data or is that gone for good?

2. Is there a recovery or a prog that can allow the phone's internal memory to be read like a flash drive or a standard drive on a pc so that I can possibly try to use data recovery software to try to find useful files?

3. Can I get a set of efs backup files from this phone from someone else and perhaps edit the file and enter my IMEI information through notepad or another program?

4. Can a stock rom recovery install what I need?

5. If no to the previous 4 is there any online services or companies that could possibly fix this?

6. or am I completely f***ed?

Please if you have no constructive criticism, thoughts, things to try, or have had any experience in dealing with this issue please move on, I have kicked the **** out of myself enough to bypass trolling.. for all those who want to genuinely help and have some understanding of what I am asking/have done, please help and I will do what I can to reward you in turn. THank you so much to any and all! -j
