{Q} IMEI Fix Method - IMEI Restore however no ATT 4G

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?

I know there's been multiple threads on this topic but I can't figure out how to solve it after reading each one. Here's my story. I rooted it and then flashed CM10 via cwm recovery and everything was working fine. One day later without doing anything my 4g started slowing down and eventually I can't get anything but edge. I looked around xda and found out that i might be missing my IMEI. Sure enough my IMEI was a 0. I tried recovering to a back up but that didn't fix it so I injected it back in via Peoplearmy's method. The IMEI is now in place but I still wasn't getting anything but edge. I tried using odin to flash it back to stock which worked but I still wasn't getting anything but edge. Does anyone know what I need to do to fix this? I have contacted Peoplearmy but he hasn't replied yet and i need this fixed asap so it would be great if someone could help me out. This is the T-mobile version of the s3. If you need any more information please ask. Thanks. I would post this in another place but I don't have enough posts. Relatively new here.

[Q] Will returning to stock clear up no imei?

I've spend the past day or so just reading these forums. There is tons of great information here. So much so that it can be overwhelming. Since I am new here, I thought I would at least ask to make sure I understand before I brick my phone.
I bought a T-999 from someone. The phone works fine but it does have some issues. Primarily, no imei is showing and the counter has been tripped. Since I don't know what this person did to the phone, I assume the best thing to do it to try to take it back to stock and start over.
I've read the sticky thread by DocHoliday and just wanted to make sure I understand before proceeding. I'm not particularly concerned about rooting the phone at this point, just getting it back to stock to see if I can clear up the imei issue and whatever else may have been done to the phone.
I have odin, the USB drivers, and the November Jelly Bean Firmware all ready to go. So now, I should be able to return the phone to stock following the sticky.
Does anyone know if this will also clear up the no imei issue or will I need to do something else to clear up that issue.
Update: Well, that didn't work. In ODIN mode it shows:
Custom Binary Download: Yes (1 count)
Imei still shows: 0/08
Any ideas?

Look in the dev section for imei injection. Only way you will get it back and get HSDPA+ back. No going back to stock will not get it back.

[Q] lost imei,sim, and service after custom rom

so i'm in need of some big help here. i have a t-mobile galaxy note 2(SGH-T889). I recently rooted my phone(clockwork) as was looking around for some custom roms to put on it. then i came across the hawkish extreme on here(was blown away by it by the way, pure awesome). me being foolish as i am opted to put this on my phone. just i didn't realize until it was too late that it was for international phones only. so now i have no service with circle and the diagonal line through along with the imei saying unknown. i'm completely lost i've seen a couple threads on here as to how to recover but not any dealing with my type of situation. i don't have efs backed-up. i'm a little freaked out right now so any help would be grateful.
any other information you need just let me know.
thanks in advance.
[edit]: i fixed thanks to teshxx SGH-T889 Factory Images, Roms, Kernels, & Modems thread

Start with flashing stock t mobile with odin. You might get lucky and it will be fine, if not the are guides to help you get your imei and signals back.
