Lost Data completely after Rooting/Flashing

I rooted and flashed my phone and everything worked great but my data package stopped working Completly. I restored the phone back to stock ROM using Odin but still no data (wifi still works). I checked my IMEI number and it appears fine.
The instructions i followed to root the phone was the one where you do not tripp the flash counter, and I backed up IMEI using the NV reader, and the ROM i installed was the Sonic Rom. The only thing I think I could have done wrong is when I went to use the NV reader I accidentally started backing up the entire array of numbers and I canceled the operation midway through. I then just backed up just the IMEI and installed the ROM.
Is it possible I corrupted something when I hit cancel? And please does anyone know how I can get my data working? I was on the phone with tmobile for over an hour today and they were zero help.
thanks.

Exact same thing happened to me..I used PeopleArmy's method and tried re-injecting the correct IMEI back into the phone for a couple hours, then suddenly, my data started working again out of nowhere. Really weird, but it fixed my issue..good luck to you!

Thanks for the reply. did you use PeopleArmy method to recover a lost IMEI number? My issue is a little different. I still have IMEI numbers but I have no data signal working on the phone at all.
I did not get many many replies, maybe my original post was hard to understand...
My H+ and 3G indicator lights blink as if they are working but my phone is completly unable to use any data services. WiFi works, Cellular Voice works but no data.
When I first got the phone everything worked great but after I rooted and flashed it started showing a screen on my browser indicating that my data plan was not compatible with my handset. Tmobile could not help,since I have the correct data plan, my previous phone is the awesome HD2. Please let me know what I can do to fix the phone.

restoring efs with nvtools/qpst

hi guys, i flashed the lte modem on my phone and it seems that its wiped out my efs folders, ive been trying to restore my efs folder with nvtools and qpst, neither seems to work since somehow dm mode is not responding to them
any solns? ty in advance for any help
a couple of things:
ive already odin'd back to stock, no luck on restoring efs(perhaps im doing something wrong?) i dialed *#7284# and put it into the RNDIS+DM+MODEM mode, nvtools says phone failed to answer while QPST says that comm7(the samsung serial port) is not a phone
its pretty had to do this since the phone is rebooting itself every other minute

Questions and help issues go in Q&A
Thread moved
Thanks

Been there, sucks. For me to get out of the constant restarts I had to flash the lte modem again. Flash stock (odin) flashed cwm (odin), put the modem on my external sd card and flashed that.At least that way I could work on it a little. And below is basically what I did to finally get it to work. Hard to say all my steps as I was trying everything.
Well I dont really know how I got mine back to life, tried all the standard stuff from the threads,got my imei back but had no network,network type,service nothing helped. last resort I said whatever ill try anything now. Came across this
http://galaxynote2root.com/galaxy-n...3g4g-aws-bands-on-att-galaxy-note-2-sgh-i317/
whatever it did it restored everything (cold see carrier,network,etc)but corrupted imei, next i followed this guide

If you need this is a complete no imei nv backup I used before flashing my imei with the generator
http://db.tt/4hunZ7qy
used the imei generator, then the writer (link on post does not work for the imei generator,so found it here
http://d-h.st/vVV
Wrote my imei back and presto, back in action. Fully functional again, including 4G
Like I said this was a last resort, but worked

got it fixed on friday, was so tired that i went to sleep
basically i followed someone's post on the forum(forgot name) and flashed the tmo modem, since the mct one always gave me the bootloop, then i enabled DM mode and finally got nv tools/qpst to recognize my phone, it appears that the issue was that the drivers does not recognize the new modems..
anyway, once i was done restoring nv, i flashed the tmo lte modem and paranoid android
now i have my imei back and i can use lte
although my bluetooth address still says unknown..not sure if normal

My bluetooth also says unavailable, I would think if you are not hooked up to bluetooth then it should say unavailable. Im to scared to flash the tmo lte modem again...

Lost and restored IMEI, still only on EDGE

Hey everyone, so somehow, by flashing a kernel, I lost my IMEI/EFS folder. Of course, I didn't have it backed up to begin with. I restored my IMEI using QPST, but I still only manage to connect to EDGE. I restored an old stock rooted nandroid and tried again, to no avail.
In settings, I am still missing my ERI version, and, as I said before, I can connect to EDGE, make phone calls, receive texts, etc. but no data, so something is definitely missing.
Could somebody give me the definitive method to repair this problem? Thanks!

Ok....tried to Odin back to Stock rooted (Root69) and I'm hung at the Samsung boot screen. Can anyone lend a hand?
EDIT: Fixed with factory reset. Still stuck on EDGE...

Can you clear the imei number with this tool?

I would suggest warranty replacement as the best option. I ran into the same issue, and that is what I had to do. Apparently, the NV items carry a lot of configuration information. After I did the warranty replacement, I did a difference between the NV backup from my old corrupted GSIII and the new one before I returned it. There were some substantial differences, much more than just the missing IMEI!

[Q] IMEI Not Recovering!

So I downgraded from 4.3 to 4.1.2. Everything works normal except IMEI which is and incorrect number. I backup my efs partition with my modem and restored it, and yet, it still fails to change to the correct number.
So I re-flashed stock 4.3 and IMEI came back again. When I went back a to 4.1.2 second time, the problem persists. What am I doing wrong???
SOLVED: Updated modem partition.

corrupted efs folder, how to recover?

I rooted my phone, flashed twrp as the recovery, then proceeded to flash cm12. Something went horribly wrong, and I had to flash back to factory stock to get it out of its boot loop. Now tho, the baseband is unknown and the imei is null/null. I do not have a nand backup of any sort. Is there a way I can recover the efs folder to make the phone a phone again instead of a small tablet? Wifi/BT still work just fine. Never had this happen with any android phone before. Thanks

Just Odin back to stock.....everything will be fine

THanks, had to flash it twice with odin for it come back to a working state. Dont know whats up with it still as mms still doesnt work even tho all my settings are correct. Off to the local cell office, but at least I got cm12 flashed, and the gps, sms, calls, cell data all work.
