[Q] Help needed

Hello i am hoping that someone will be able to help me. I tried rooting my phone and when it booted up i don't have a network. Now i can't' call/text/checkemail.
I tried resetting to factory settings and that didn't work. how do i remove the root so its back to stock?
Thank you!
Rooting phone has nothing to do with the network you did something wrong .
Remove root by flashing full stock firmware matched as close as possible to your original firmware .
INSTRUCTIONS
Stock Roms .and csc

thanks for the quick response. how do i go about finding which on is closes to my origonal firmware? sorry for the ignorance?
you should have checked your firmware version first before rooting
well crap. does this mean i am out of luck and need to make an insurance claim as being lost? my issue is its with Sprint and the phone just came out last friday so there isn't much information on the web on it

I replies as per Samsung Galaxy SGS2 i9100 model and know nothing about a Sprint phone .
It would make sense to either look for a Sprint thread here or if Sprint is in the stock rom links i gave download the latest .
If it worked before root the strong probability is that you made a mistake its usually recoverable though but no idea how you rooted .

[Q] I have a wrong IMEI in my S3 GT-I9300 : 004999...

Hello and good evening everyone
Please I need help because I'm really stuck. I have a GT-I9300 smartphone Samsung Galaxy S3. I manually installed XXUFME7 Jelly Bean 4.2.2 and everything worked fine until I had a problem with "safe mode". I did everything to exit, but I could not. So I decided to go back and install the official 4.1.2 Jelly bean. I did, but it did not solve my problem. I decided to still reinstall version 4.2.2 Jelly Bean. But I find that I have no network. The wireless works fine but I can not call or receive communication. Checking, I see that my original IMEI has changed and now starts with 0049 when he was beginning by 3554 .... So all these manipulations made ​​me lose my IMEI. In addition, I never saved the efs directory of my smartphone. What can I do to get the IMEI of origin of my smartphone?
My /efs folder is empty !!! Why ?
Thank you very much for any help
Why is because you failed to read the faqs and guides .

Wrong answer. Nothing to do with imei problems. Please understand issues before posting solutions!

Galaxy S3 IMEI problem

Hello people.
I'm new here and therefore perhaps not as much of an idea as you.
My English is not so good.
My problem:
I flashed my phone with the Rom Xperianze.
Now I have the problem that I have such a great developer Imei.
've Tried all things. I also flashed back to stock.
It all brought nothing.
Do you have to send in some ideas except maybe the phone?
Thanks in advance
