[Q] IMEI changed after flashing rom!! - T-Mobile, Samsung Galaxy SIII

Hey guys, just registered to post about a problem I've encountered with my galaxy s3 i9300. I rooted my phone and flashed cyanogen mod 10.2. After this everything looked good but then I realised that my mobile network wasn't working. I searched around the web for a few weeks now and found out that the problem was my imei number. My IMEI number changed to 004999010640000 from the official number under my battery and I couldn't find out how to restore it. Apparently I should have backed up my EFS folder before the rooting process but I didn't know.
Is there any way to restore my current IMEI number back to the official IMEI number without the EFS folder?
I'm new to this sort of stuff and I would really appreciate it if somebody could tell me something about this problem..Thanks in advance!!

You posted on the wrong Device forum. This is one of the US version of S3. You should really be posting to the International S3 forum over here.
There are possible answers to your problem. But best answers if you ask on the right forum.

In this case you definitely need to post in the I9300 forum. Yours is a known, common issue, but the tools we have will not work on your model. I don't know if there's a fix for yours, but if there is it'll be in your forum. Good luck!

Broken carrier, which ROM?

This is pretty basic, but I can't find a answer anywhere, I'm sure I'm just not searching it right, but anyway I bought a rooted SGH-I317 with t-mobile as my carrier, with Android 4.1.2, on Clean ROM 3.3. I've done a cwm back up, but when I pick a new ROM will I choose a t-mobile version ROM since I'm on their network or a SGH-I317 ROM? And thnx in advance for any help you can give

Hello, and welcome to XDA!
Please wait while I connect your question to this forum (where your device experts can be found):
> AT&T Samsung Galaxy Note II > AT&T Galaxy Note II Q&A, Help & Troubleshooting
Note that to respond to replies, you will need to create an XDA account.
Also, I am confident that flashing a T-Mobile ROM on an AT&T device (since the model numbers are quite different) will have dire consequences.
Hope this helps, and good luck!
Hello I sent that question last night before I made a account here so I'm putting a name with this question so if you can help, and maybe even offer up some suggestions of which ROMS run cross platforms it would be greatly appreciated. Thnx again
You can use ROMs for T889 (T-Mobile), I317 (ATT), or N7105 (international?) do NOT flash a ROM if it has a modem with it that isn't what your specific device is (I317). Majority of the ROMs already have the modems stripped out so they can be universal for the three devices just read the details of the thread by the poster of the ROM.
Thnx for your help! I read in another post that if you install a new ROM with a updated boot loader you can't revert back, that won't affect me re-installing my cwm back up if I were to flash either dn4, cyanide, resurrection remix and something went wrong? I currently have I317ucalJ2 boot loader. Once again thnx for anyone's help they can offer me.

Please i need your help to find a specific rom version 4.1.1

Hi guys !
First: Sorry if this is not te area to post my thread, Mods please feel free to move it where it may belong.
Second: I have a Samsung GT-N7105 according to XDA Forum, SGH-I317M writed on the Back of my phone or T0lte on te CyanogenMod forum (lot of names) the problem is that the phone its "Unlocked" for any company but last week my Data Plan ends, i pay the renovation but they give me another CHIP, from other company and put my data plan on it. When i put it on, the rest of the day it was working with out any problem, but in the night just stops working and asks for a Unlocked Sim Code... there's the problem. I look for the solution here on XDA and with the 4.1.1 version i can get on to "Service Mode" and use the options to unlock it for any carrier. I looked on the past threads, and other links and forums. But i can get that specific version of android. So i wonder if please someone from here have it? ad can share it to make testes to unlock my phone.
Thank you in advance and hope somebody can help. looking forward to any answer.
Which phone do you have according to the imei?
