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
any ideas on where I can look for a fix?

Hi there!
I recently discovered that my phone has totally no service after about 2 weeks flashing with V20F rom so I flashed back to Hong Kong stock gb rom. However, the phone cannot detect the sim card thus still no service and when I check the IMEI with *#06#, only a blank box appeared. I checked the efs folder and it was blank. As my phone was unrooted, I sent it to the service center. Just now, they called me and said that they my phone is rooted and the problem cannot be fixed (did they really try to fix it??!!) and needed to change the m/b which costs HKD2000!!!
My question is do I really need to pay for the m/b or are there any cheaper ways to recover the IMEI??? I have searched on the web but there seems to be no such tutorial for P930 or P936.
Oh and by the way, I am not sure if I have a backup of the efs folder as I once installed CWR.
Thank you for your help!

I had the same issue well the window saying 'No network or wrong IMEI' so I too will wait to see any responses and I only put those numbers in because I heard that it may open up the internet speed or stop the drop of wifi signal, just not sure of any of that lol

I don't think yours is the same issue of mine as I don't have any error message. The IMEI is just literally blank. I really hope someone can help me. Anyway, thanks for your response!

Hi! No luck! Unfortunately, the above solution requires some sort of chip which this P936 hasn't. I will give the phone to a local electronic store to see if they have any clues. Thanks anyway!

Dial *#06# and check what msg pops up?
If it is null than its because of downgrading or wrong update
If its 00something than its a corrupt imei

You probably upgraded to a new firmware type of rom, then went back. This can cause the EFS(Root folder for some phone information) to be corrupted. Did you make backup(Which are most likely to be suggested in any rom thread found here)? That could solve your problem quick.

Hey guys I bought my sg3 about 3 months ago from a friend who had cynogen mod on the phone and it worked fine but I had cynogen mod on auto update and now my imei shows as 0 via *#06# and I cant call or text etc. Unfortunately I do not have a backup from when the imei worked because I didnt expect it to do this. So far Ive removed cynogen mod and reset it to stock firmware but im having the same issue any suggestions?
Its the SGH1747 version

Your baseband is probably corrupted. You may try reflashing a stock modem/baseband via recovery. I had a similar problem once, although I was on stock ROM, and re-flashing the modem zip worked.
I, however, tread very carefully here as I am aware the forum is wary about discussions relating to IMEI.

Don't know if you're willing to pay to have this repaired but here's a site that does it. I've done stuff with them before. Very good service.

You can look up peoplearmy's method (google it). You will not find help on how to fix IMEI on XDA. I had my IMEI wiped out a while back after flashing a bad rom. I had to get it put back, and then had to get LTE back.
Good luck.

Can you go to Settings => About Device and see what you have under Baseband version? Whilst you are there, also check what Android version it says and the build number.

Everything looks OK as your baseband version would likely read 'unknown' if it's bad. You may, however, still try re-flashing the modem via the method posted in the attached thread ... Please proceed at your own peril as I offer no guarantee that this will work or will not result in damaged phones,
http://forum.xda-developers.com/showthread.php?t=1831898
Please note you will need custom recovery (e.g. CWM or TWRP). You will find instructions for installing custom recovery at the bottom of the thread. If this doesn't work, then you may try doing a hard wipe from recovery and reinstalling everything including system ROM, modem and kernel.
Hope it works out for you.
Simple fix is to reinject imei which located behind the battery.. But sometimes for some reason if you do this, you'll stuck with edge network, can be fix though but you gotta go back to stock in order to do so

I'm in the same boat as you once were. I lost my imei and had to inject it back, now I have no LTE service anywhere.. It says LTE but no internet connection. Any help? Sorry if I threadjacked here but I've been dealing with this for a year now and I really need a solution...

you will have to google peoplearmy imei lte and find the tutorial on how to restore imei and get LTE back.
You will not be able to find the thread on XDA because XDA deleted it sometime ago. I was like you and lost my imei. Once I re-injected it using a tutorial on XDA, I was stuck on edge. Then I finally found peoplearmy's tutorial, downloaded the programs and followed the steps to get LTE back. I got it back and haven't lost it since.

I can't find the link, can you PM me it?
I had that happen to me with a 0 on my phone and was able to get it back I had no backup either what I did is go on the NV Data restore or NV writer thread and downloaded the NV writer and put myself back on stock ...I went thru a few pages in the post and someone had a file where you could put your IMEI into that file maybe it was set up thru notepad but you could fill in the zeros with your IMEI and name it I think a txt.file after then open the NV writer and instead of backing it up cause you can't just restore that file where you fill in you're IMEI and it went right back into my phone. There also a video on that page how to do it. You just need basically that file to put your IMEI back in. I might still have it if not keep going thru the post took find it. There a picture of what it looks like to restore if you list it but every time I tried to open that link to restore it wouldn't let me. Hope it wasn't to confusing but it's basically a white box with a bunch of zeros and replace the zeros with your IMEI and save it as atxt. File I believe and just restore it as shown in the video for backing it up but just restore instead it does work cause I didn't have an IMEI on my phone it just had a zero

Well then, from what I know I the easiest way is through efs backup. I really hope you have made a full Rom backup if not I remember there was another method but it wasn't going to be easy. Hopefully someone here can guild you in that direction.
no I don't have a backup of the rom. I thought that the engineering mode menu can help. I saw a video tutorial online about it. And if u still have a better option pls guide me through
