To start off with, I'm a complete beginner on rooting/flashing and I didn't even cause the problem in the first place, but I may have a better understanding. So a friend was trying to downgrade his phone to 4.1.1 so it could be unlocked through the service menu. I'm not completely sure what files were used but it did downgrade to 4.1.1 but it now says no service and the IMEI says NULL. Please help!!
Also, it's not the "not registered to network" error I have seen mostly while i was trying to search.
Thank you
Try to use T-mobile forum and you may have better luck.

I am really hoping that someone can help me. I lost my IMEI on my ATT GSIII. I used the IMEI restore methods supplied by Geek & Peoplesarmy to help correct the problem. My phone was already corrupt before I found their repair methods, so I didnt back anything up. I started off with the "IMEI Injection" process. I was able to inject the IMEI back into the phone succesfully, however I am still stuck on 2G/ Edge. I did as much troubleshooting as I could before posting this question. So far I have flashed stock ATT ROM, Wiped & Factory Reset, pulled battery & SIM card, etc. DOn't know what else to do.
Im hoping that somone with more experience can help me. I can not post directly to the IMEI Fix Tool Forum at this time, so hopefully I can get some help here.
Thank you very much in advance!!!
Too bad nobody knows cause I have the same issue!!!
You need to download the App in post #3. This will let you connect to data fully. The IMEI injection only does what it says. You'll need to use this tool to restore full data. I have used to fully restore everything.
Looking for answer.
I have the same exact problem with my Galaxy S3. I came across this forum and was excited too actually got excited! Except when you click on the link in Bam1789 replay it leads too a dead forum. Do one of you have the correct link?

First: I have searched... alot.... seriously alot of searching
Second: I would have posted in the appropriate forum ( AT&T, Rogers, Bell, Telus Samsung Galaxy S III > AT&T Galaxy S III Android Development > [FIX/TOOL] Backup/Restore/Fix IMEI & Data Restore Tool v3.0 - Updated 11/01/2012!!!)
BUT I have less then ten posts so I guess I have to put it here.
I restored my IMEI via the instructions in the forum, that went ok, but when I try to load the .qcn backup file into SGS3 QCN Generator the .qcn backup cannot be found on my pc.
I made sure to put it in the correct bin folder and when I go into QPST Software Download the file shows up, but if you browse or even search for it outside of that application it cannot be found...
I'm sorry for posting this here I would rather posted this as a reply in the right forum but the ten posts thing, I guess I'm a noob but I have rooted and rom'd 4 phones now with 12 or 15 different roms and haven't had any issue like this.
any help would be much appreciated.

SGH-T999
4.0.4
Baseband: T999UVLI6
Ok I flashed stock everything from odin, back to Baseband: T999UVLH2 and tried the whole process again and it worked, except I still don't have 4g data... so i could use some help if you know of a way to make my 4g come back pc also says it is unable to identify device when I connect via usb...
Only thing I can think of is when you restore your qcn backup, use the very first one you ever made. Dont know why, just that multiple members have reported that as working for them.
If it doesn't help, PM peoplearmy. I believe he has a file that should fix you right up. Or will at least know what to do.

4G is back, apparently all it needed was another reboot and to sit about 10 min...
Thank you Doc for the reply, I didn't know what I was going to do if all of that didn't work.
If anyone has searched this problem and you have found this thread, please PM me and I will be glad to help you as best I can.
Hey everyone,
So I recently ran into a weird situation with my Rogers Samsung Galaxy S3, I went to the Rogers store to get a LTE sim card. After activating the sim card and putting it into my phone I realized that I was only getting Edge. I'd like to point out that I was getting up to H+ (or 4g) before I purchased this new sim card.
Anyways, I looked into this problem and I determined that I had lost my IMEI. So using QPST and the QCN generator, I was able to get my data connection back. However, I did noticed one slight change. Before, my phone used to show 4g and now it says H+. To my understanding, these two are the same thing. Please correct me if I'm wrong. As for LTE, I believe it shows up as 4g on my phone.
My first question, is there any way to get my phone to show 4g for H+ and LTE for 4g? --> which to my understanding is the normal set up for the GS3.
My other concern is that I would like to know what caused my IMEI to be lost?????? What are some possibilities?
I am rooted and I was using Drew Garen's Jellybean M7 rom. Just before I purchased the new sim card, I flashed back to Rogers stock rom. That is all I did! I've done this many times and I've never had a problem with my IMEI.
Thanks everyone for your time. If you can help out in any way I'd greatly appreciate it.
For all I know, flashing ROMs randomly cause you to lose your imei. No one really knows why (correct me if you can). There's a thread sticky somewhere that links to a tool to restore it.. Best of luck
one way to lose your imei is flashing att modem on Canadian i747m but
flashing back the right modem should give you back your imei if that's was what cause you to lose it.
Is there any way to get my phone to show 4g for H+ and LTE for 4g? --> which to my understanding is the normal set up for the GS3.
On stock Rogers gs3 you should see LTE when connected to it. Try doing a factory reset afrer flashing the stock rom.
I had the same experience.I had no clue how it happened cz i didnot flash any custom rom apart from jellybean bell leaked rom(my s3 is Bell).Anyhow you will have to manually restore imei if its not already backed up.There is a tool for it and to get Hsdpa working as well.

Is it possible to restore the imei if you did not back up already?
Yes its possible. You need to reinject your IMEI (found behind your battery). You can do this using QPST and the QCN generator. Theres a list of instructions on this thread

Goodluck
First off, I'm not new to rooting etc. I've previously rooted several HTC devices and achieved s-off which for those ofyou who know HTC phones, know that the process can be difficult.
That being said, I've recently switched to my very first Samsung device and have achieved root with no problems, but was unable to flash any roms. After searching for a week and coming up empty handed, I decided I'd try the all in one toolbox. I downloaded it and when checking my build number, I discovered what my problem likely is.
My phone is with telus and is the 1747M.
How have I managed to get that build number? Can I change the build easily enough? Should I leave it on that build and just use roms meant for the i9300?
Thanks in advance for your help!!

DO NOT USE i9300!! If it is a carrier device (i747[M]), which it is, you will brick your phone and have to get it JTAGGED. You need to only flash ROMs located in this section.

Please start by reading this thread, reading that thread will help you understand Rooting and installing Roms. Reading that thread will save you from Bricking your phone, as you would have done if you'd flashed a i9300 Rom onto your phone.
Sticky Roll-Up A Guide To All Guides and Q&A's
I've read all of that stuff and the answer to my question isn't there. My build number is the same as listed in i9300. I wasn't going to flash any of those roms without finding out if that was the solution to my problem. I don't want to brick my phone and therefor I stopped doing anything to it until I was able to get some help on how to proceed. I only discovered the build number issue when I tried to use the all in one toolkit and noticed my build number didn't match any of the telus ones but the 9300 ones. I guess I'll just have to continue researching on my own to figure it out. I wouldn't have posted if I wasn't stuck. Thanks anyways

Don't pay attention to build number.
Flash with Odin a pre rooted i747M image. (That's the easiest way)
Do not and I mean DO NOT flash,use,mod anything i9300 or anything international.
Please read some more. A lot more.
Before you end up with a paper weight.

First of I must say.....I am not that advanced in doing these types of things!
I have a AT&T Note 2 that is running 4.1.2 Android. I have read many threads about unlocking and most say I have to downgrade to Android version 4.1.1, is this true? If so does anyone have EASY instructions for doing this from a MAC?
Then I read in other threads where people say.....DO NOT downgrade back to 4.1.1 you are asking for problems. Instead have it rooted?
I am lost and just need a honest answer and help getting it done, before I leave the country and need it unlocked for use with international SIM cards.
Can anyone help walk me through this??
Thanks in Advance,
Greg
You only need to revert the modem to 4.1.1 (i.e. ucalj2 for att) then follow this guide...
http://forum.xda-developers.com/showthread.php?t=2176719
You can then flash back to the modem you are currently running. Search the forum to find cwm flashables for both.
Depending on where you are at in your contact, you can also request an unlock code from your carrier.
