Hey I'm from india and own an i9500
bought 5 months ago
I was using my phone normally and flashed a stock rom with ODIb
the phone booted up.
The problem is that I have emergency calls only and my IMEI has been changed to Fake IMEI
1) my phone is out of warranty as some moisture traces have gone into iy and samsung asks for 200$ for every small problem they need to change the board
2) I don't think so I have the EFS backup
Please Oh please someone guide me what to do?

There's a thread on that here. You could try that, but I think that without a backup, it's going to be pretty hard to get it back up. First thing I do when I get a new phone is to backup the EFS.

Did you actually tried to flash your original Stock ROM with Odin? If not, try other stock ROMs.
There's another ref link here: http://forum.xda-developers.com/showthread.php?t=2393289
I recommend you read through that thoroughly.

Yes I did flash the stock rom with ODIN which I successively used before
I read it but this is actually getting impossible for me.
After the phone shows generic IMEI.
will backing up the efs help now?
Also I flashed CM 10.
that also didn't give me back my IMEI.
really appreciate your help
and would be really grateful if someone guides me through this catastrophe.
Also I forgot to mention that I update to stock MJ5 4.3
I read that it changes the directory of efs?
Please someone help me!

Since you updated to mj5 you'll have to use that firmware version in odin.
maybe
Maybe you could wipe Dalvik and cache memory, then do a factory reset through the recovery menu. This will reset everything of your phone, so your IMEI should go back to it's real number(you'll lose all your data so make a backup before doing it).
Have you also tested if it's not the SIM that doesn't work by putting it into another cell-phone?

Sim isn't the problem.
Also wipin dalvik Cache might now fix the problem. But I will try it
thanks
any more suggestion?
A factory reset/wipe Dalvik ain't magically fixing this. If you've gone back to stock (a rom released by your carrier) & your IMEI hasn't returned & you have no backup, you're boned. Service centre (more expensive option), or ask around local mobile repair shops; they might be able to help more cheaply.

sorry for the questions but still a noob
i have the same problem
I had chinesee android 6.0
- changed region to hw/eu
- flashed to b052 - imei - gone
- flash to b136 - lack of imei
- flash to b170 - lack of imei
- tried to update to full b170 - update failed by local update and force update
- tried to flash to b046 - lack of imei
- tried to local and force update to full b046 - still nothing
help please
you need to flash B52 , then move to B170 via "OTA" update
here is a thread that talk about that IMEI issue
Link : http://tundevs.blogspot.com/p/huawei-p8-marshmallow.html
Good luck
any logical help from person who can read my problem??
nothing working
Any ideas how to fix that problem?
In my case, the ota to B170 update will return bootloop issue.
EDIT//12.5.2016
After lot of tries i finally fixed the phone and baseband returned.
The process that worked for me was installing B170 via fastboot, than full wipe.
Its strange the same thing didn't work before, so I was keep trying and finished with success
How did u use fastboot?

Could you maybe post a link where you found the B170 ROM, or dig you extract the files(system.img;boot.img;recovery.img;...) from the B170 update.app file, because nothing is working for me. :crying::crying:
And I have no idea what to do now.

It was a long time ago, but because I thanked the post just before the on you quoted I believe the guide linked in there worked for me.
I really hope that you will be able to fix your IMEI.
I just recently flashed CM13 to my phone and since then i haven't been able to use my network. After looking about i got told to check my baseband number which turned out to be "unknown". I then checked my IMEI number which also turns out to be "unknown". Iv looked at countless posts on all websites to find a fix for this but i still cant seem to find one.
Update:
I have tried to backup my EFS files from my working backup and then restore them on CM13 but havent had any luck.
Iv also been told to update my modem to a 6.0.1 version but i havent been able to find one after searching everywhere.
If anyone can give me link to somewhere that i can download an updated modem or give me clear instructions on how to restore EFS partitions that would be much appreciated.
Is anyone able to help me at all with this? I will provide any screenshots necessary to fix this problem if i need to. I have also continued to look at more posts about how to fix this and still cant seem to find a working fix.
Sorry I don't know the answer but didn't you make full Backup before flash rom. Including esf partition.
If you make backup try to restore.

i made a full back up but i have no idea what esf partitions are. If i didnt back them up does that mean i cant fix this?

It's always a risk flashing a custom Rom. You must have a Nandroid backup or at least a backup of your EFS.

I haven't flashed a CM Rom since my Galaxy S1 days 6 years ago. I did experience then what you experienced now, getting a corrupted IMEI. I'm not in a good position now to help you as I don't have much experience in CM Roms. Best to ask help from the CM thread.
Alternatively, you can try some EFS backup and restore apps from Playstore to restore your EFS (one of which is Flashfire by Chainfire), or you can search in Xda how to restore a backup of your EFS.
i have updated the post with a little more information if anyone could please help me with this issue that would be great.
anyone willing to help me with this?
