[Q] Generic IMEI after OTA 4.3 upgrade

Hello to everyone, I was wondering if anyone can help with this. I have a Galaxy Note 2 branded by an Italian company (3hg Italia). It recently received its update to Android 4.3 (update N7100XXUEML2). It was the official update OTA, the phone is not rooted and it had the stock ROM on it. The update somehow messed up my IMEI making it appear as the generic 0049 forcing me on "Emergency calls only" mode. I already tried flashing the same ROM with Odin and repeating the update with KIES, but while the updates always results successful the IMEI remains 0049. I never made a backup of the EFS folder for this phone since I haven't rooted it or flashed any different ROM on it yet. There is any chance that the phone made an automatic backup? I live in the States right now and Samsung tells me I need to ship it back to Italy to have it fixed, but that costs a lot and would take forever, and I would much prefer try to solve the problem locally. Any suggestions would be greatly appreciated, if not for any fix that I can try myself, at least some place on the West Coast that can fix the problem!
Thank you!
Lorenzo

Oh I forgot to add that because of Hardware problems I recently sent my phone to Samsung and they replaced the motherboard, which fixed the problem I was having. I don't know if that could be related!

I'm afraid that fix works just if you have your actual IMEI, I instead have the generic IMEI that starts with 0049. But I will check it out! Thanks!

Then you should simply flash another modem from here : http://forum.xda-developers.com/showthread.php?t=2044937 ... flash a custom recovery first.

So I found someone nice enough to give me a hand with this situation, but still no luck yet! Here what they say:
At first glance, the EFS data on the phone was corrupt. I re-generated
that data and restored it to the phone without success.
The GSM radio itself is operational, and the firmware for it is
installed and functional. diagnostic data flows to the towers and back
to the phone but it's not reading the IMEI from the copy of
nv_data.bin contained within EFS. I've re-generated and installed
those files as well, again with no luck.
I rolled the device back to it's original factory firmware and radio
baseband, then ran through the update for the radio baseband, which
also regenerates the contents of EFS, and still no luck.
Given the situation, anyone have other suggestions?

[Q] imei 0

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

[Q] Enable DIAG CM 10.2.1-d2att

Hello XDA community. I have never posted because you all do a fantastic job with your forum and I have been able to figure everything out based on the information here. However, this has come to an end...I have been scouring this site since Sunday hoping for a resolution and just cannot get anywhere. So, I am leaning on you guys to see if you can set me straight. I have lost data connection and IMEI was 0.
Firstly, I do not have a copy of my EFS. Idiotic I know.
I flashed Stock ROM and injected IMEI with NV reader writer and IMEI came back.
Reflashed CM 10.2.1
Flashed 1747UCUEMJB Modem
Flashed 1747UCUEMJB Bootloader
Still no data connection...
Tried to reflash to stock to use DIAG mode to allow me to use Peoplearmys FIX on stock rom. I can't downgrade boot loaders, so Stock ROM is out of the question from what I understand.
I have tried several time using terminal emulator and Smanager to run the scripts Peoplearmy has provided to enable DIAG mode in AOSP, but I keep getting error messages "No such file or directory"
Can anybody help or point me in the right direction? I need to figure out how to get my phone into DIAG mode and I think I can proceed, unless anybody has a better suggestion. If you require anymore information about my situation, please let me know.
Thanks in advance for the assistance.

So I followed that to get me back to Stock Rom and it worked perfectly. Then, followed peoplearmys advice to inject IMEI, data fixed.
Now just trying to reroot and having some issues, but my brain is fried. So, it may be another day...

in the same post he have mentioned how to recover lost imei/efs please read
How to recover lost IMEI that happens with downgrading ROM
If you have lost IMEI just by downgrading (as said by above by flashing older ROM), still you can recover IMEI without having EFS backup.
-Again upgrade ROM will restore IMEI OR
-Flash latest Modem. You can find it here.. You can download MG1 modem and flash using PC Odin with 'Phone' tab instead of PDA.
Remember above said works only if IMEI is corrupted by downgrading ROM only, if it was corrupted by other things, this won't be helpful.
Also Read This, if you have issue restoring EFS OR device stuck to factory mod.
Hope this will find helpful to all newbies regarding question about EFS and IMEI problem. I have posted this to general section so newbie can post to it if they have any queries.

i did the result did not change , if i flash custom rom can i fix network eg pixel experience rom ?

How long was it working on Eu rom before it gave you a problem? Maybe you temporarily sim unlocked the phone for 30 days and that ran out?
OnePlus says you must go through tmobile to get it unlocked. Tmobile does need it on their network for a day or so to be able to unlock it. (They tried to do mine manually but there was no data for my phone and there is an exchange that takes place on their server so it has to be online).

Looks like the efs may be somewhat corrupt. Hope you backed up modemst1/modemst2 partitions like the conversion thread suggested you do. You'll want to flash these both back on and then problems should be resolved. You cannot use someone else's partitions, has to be yours.
MSM'ing will not help this situation. Need to unlock permanently using t-mobile's unlock in original ROM after you've restored those partitions. It blows an efuse when it does this, no custom rom can be used as a workaround.

I also had the same problem on OP9. It happened after playing with modemst partition.

unfortunately i tried that too. this problem happened because i deleted modemst1 and modemst2 file in eu rom. I guess the tmo unlock application cannot read the phone's information so the unlock is refusing to bind.
