Ok guys heres whats up. I just noticed that my IMEI turned into generic 004999010640000. Im not sure if this happened when i tried to unlock my phone with SGS_Unlock while i was on Froyo, or did it happened when i flashed ICSSGS rom on it. I dont know if product code is still okay since im running ICSSGS and i dont know how to check it ICS. Well, phone is working perfectly fine, texts, call, data, everything is fine, but im not sure if the phone is still unlocked and i dont have any other sim to check it. I need to use this phone in Europe in couple weeks, so this is really important to me right now. So here is my question(s) :
Is there chance that my phone is still unlocked and is theere anyway that i can check it?
Is there any way that i can restore my original IMEI and then try to re unlock the phone ??
Hope u guys can help, cuz if u dont, i dont know who can
Have you tried simply rebooting our reflashing? This happened to me once and a reboot cleared it up.

I had the generic IMEI number after unlock that is most likely the case with you. When you did the unlock did you back your efs data (nv_data.bin etc?)?
Enter *#7465625# with the dialer and if you see the following:
Personalization Status
Network Lock [OFF]
Network Subset Lock [OFF]
SP Lock [OFF]
CP Lock [OFF]
That means you're unlocked.

Flash back to a stock rom and see if it is correct then.
Best Case: It could be an error with how the ROM is reading the IMEI.
Bad Case: You're IMEI is borked but you made a backup of the original EFS
Worse Case: You never backed up your EFS but your .bak files in the folder are from the original date
Worst Case: You never backed them up, they're all the same date and your IMEI is toast
There are threads to possibly recover from the Bad and Worse case.
If it does end up being the worst case you can go to Mobiletechvideos.com and get the IMEI repair done by them. The owner is an XDA member and does a great job.
Take it from a guy who has tried just about every method out there to recover this on his own. If you don't have the backups you'll need to get it fixed by a professional.
You can try my video in case the intact nv_data.bin is still on your device. If not though you will need professional repair...

EDIT: One important thing to note is that the generic IMEI is not black listed by many carriers here in the USA but will misbehave with many stock firmwares and many other countries in Europe and Asia do indeed block access to that IMEI as it's common for stolen phones to have their EFS deleted in order to achieve this number. It also may only be a matter of time before USA carriers begin to blacklist this number as well as surely they must see 1000's of duplicates just like it on the networks daily.
I have a XT925 and when I got the phone the IMEI is 0. I want to recover it and followed the method in the forum. Everything is find except I typed in one digit wrong. Now it doesn't allow me to change #550 in NV again.
From my understanding so far, when you lose the IMEI, actually you are erasing the #550 in NV by flashing different ROM. If you had ever lost your IMEI, could you please tell me from which ROM to which ROM and use what method you had done? I really need to "lose" the IMEI again and start from the beginning.
Thanks first.
I've tried to jump from different ICS and JB ROMs but with no success. The NV #550 is still there and I have no way to modify it... May be losing IMEI is not cause by deleting the NV #550.
My sgh-i927r got sim locked for the second time. Earlier i got it repaired at a shop...
It keeps on asking "ENTER NETWORK LOCK CONTROL KEY"
This time I deleted 'nv_data.bin' and '.nv_data.bak' files from 'efs' folder as suggested on a post here at XDA.
This unlocked the phone but due to the generic IMEI i still cannot use calls, but the packet data is working fine.
When i replace the backed up files in 'efs' folder the phone again gets locked...
Is there any other way of unlocking it with the original IMEI no.??
As far I'm aware the original IMEI is now obsolete as far as unlocking the phone is concerned.
We only unlock phones using codes so unfortunately I can't really help with the rest of your post.
Hi
My friend took his phone to a store to unlock his phone to other networks and they failed and the phone has no imei now. Is there a way to recover it?
OK so another shop apparently restored the imei but is there a way to unlock it?
Bump. Is there a software method to unlock?
I got this phone on ebay, it was listed as "broken with a clean imei and unlocked" but when I got it, what I received was a "clean" imei, as in the imei wasn't there. I was able to recover the imei in other devices, but here on this device I can't, no matter how hard I try, enable diag mode or, in that case, do anything to come close to modify the imei code. It is written on the back of the phone, and I even opened the phone itself, in order to check if some modem cables were disconnected (which isn't the case). I hope that I didn't get the category wrong, and that you can help me. I was thinking of restoring the phone to stock fw, but I don't think it will change anything. For additional info, every code that i found online crashed my phone, and writing *#06#* returns a blank screen with only "imei" and no actual code. Thanks again in advice, please help me.
Settings, about phone, imie 1 and 2 should show

I don't need to see it, i need to edit it, since it doesn't exist in the phone, it has been erased
Flash stock rom again
most of the replays are pointless. the efs partition is wiped. You need something to rewrite the efs partition to restore imei.

u should backup ur modemst1 and modemst2
then erase modemst1 and modemst2 and fsg
thene write imei using QCN
Just as I tought, I recovered from it installing the stock fw but now, I've got the error that I was scared of; The network locked error. If someone knows how to network unlock a (probably not payed off) OP7 Pro 5g from sprint, then please let me know. I didn't know all these things when I bought the phone, but now I can't send it back at the other side of the world
