Hello.
I've tried to restore my original IMEI, since mine is set to 004999010640000, which is a fake. I've used repair application on Android Market and tried to fix it manually, but with no effect. It is still the same IMEI, regardless, what I do. I may be doing something wrong, but I am not sure. I run on ICS 4.0.1 and it is an original ROM. Rooted. Could you possibly help me with this case? I have an Internet connection and I can make calls, but IMEI is still fake. I also have power menu and lock screen working, so it is just matter of corrupted IMEI number, in my humble opinion.
I hope you help me.
Hello,
My phone: GSMART Roma R2 (Rooted)
I know there are a lot of threads how to restore IMEI but none of them worked when I dial up *#06#, it shows message with two lines containing "null".
I was using MIUI rom for a while and suddenly after I rebooted phone SIM was no longer recognized (before reboot I was playing with SWAP couldn't make it work so I uninstalled BusyBox (could that cause the issue?))
I already tried:
Engineering Mode: Displays "AT command is failed to send"
Terminal Emulator: Doesn't work
MAUI 3G: Flashing new IMEI changed nothing.
MTK Droid Tool - Changing IMEI did nothing.
SN Writer: Writing new IMEI changed nothing BUT when I choosed to read IMEI it successfully displayed both IMEI in the textbox. (So it looks like the IMEI actually is registered on the phone but phone doesn't seem to use it)
Manually writing MP0B_001 to NVRAM: Nothing changed.
I have used backup in CWM recovery to stock ROM, didn't work, then I did factory reset, didn't work, flashed back the stock recovery and installed update from Gigabyte site, didn't work. So basicly now my phone has stock rom, stock recovery, factory reseted and is rooted.
Thank you very much for any answers because I just fell hopeless about fixing my phone
I fixed it using solution here: http://forum.xda-developers.com/showthread.php?t=2599459
Scroll down to post with NVRAM backup, I used that backup to fix it and then just changed the IMEI numbers to my IMEI numbers.
Hi!
I have problem with my lenovo p780 4gb Chinese version (after 04.2014)
I am using vibe ui 2.0 (row version from sympty's thread)
I flashed couple Roms to find my favourite and probably messed up with the nvram.
I was having problems with no signal, nvram error in WiFi ect.
I couldn't restore my imei (done with mobile uncle but after reset the problem apeard again).
Decided to recover nvram.img but as I did not have my own backup I used one uploaded by sympty. (Before restoring nvram made a backup of my own messed up nvram, just in case).
After recovering sumptys nvram the problem with imei and nvram error in wifi disappeard . I noticed that I have symptys imei so I overwritten it with my own using moboleincle.
The problem is that I still get the network problem. No signal at all. Tried many modems also the one that have been adviced to me here (the one created by xaep).
Do You know what can cause this?
I noticed that in mobile uncle radio information the signal is not floating. Once it worked it was floating now it is still and shows 0 db 99 and.
What else could I mess up and how can I fix it?
Thank You guys in advance.

So that means that I did not rewrite imie properly?
Also, I noticed that IMEI on the baterry is diffrent than IMEI on the back of the box. My phone have been in service in China, maybe they've made a mistake?

This is strange. At least one of the IMEI'S from the box must be the same with the IMEI from the accumulator. They could switch the box on the service store, i think?

Yes probably You're right.
Soo does it matter wchich imei I will use? The one on the box or the baterry one?
Also I am still facing the problem with network. Tried many modems. And now i eaven get the problem with sim card (mmi error).
I changed the nvram for the one i got from this forum.
Can't really rewrite imei with sn writer but managed to do it with mobile uncle. (It changes, but after factory reset it goes back to the imei i got when changed nvram).
I don't really know what else could that be. Maybe it is the rom?
I really like this phone, but I am starting to think of getting a new one without network problems.

Hi. It does not matter what IMEI you are running. It doe matter to have one .
With network problem it is the same! If you dont have IMEI you cannot acces any GSM network. You can change all the modems, if you dont have IMEI your phone cannot acces network.
And yesss.... MobileUncle Tool is an temporary solved problem.
I did not encounter this proble myself. I have saw this problem to others.
From what i have read i saw that this problem could be solved with an older firmware like s119, s123, s124. Dont know how but some of the users did write the IMEI for good.
You can change only the motherboard, or change all the phone and this one use it like power bank, nice agenda, or other uses.
Good Luck.

Will try to go back to the older firmware like You said.
Basically if it doesn't matter what imei I have, than it is not the imei problem, because I do have imei after factory reset, only it is probably Yours (because i restored nvram uploaded by You ;D).
In such a case, maybe the firmware will help.
Messed up with my G925F!!!
Hello , my phone suddenly was not able to make or receive any calls or joining 3G/4G network or SMS. In other words, I was out of service although my SIM had not problems to enter the PIN password and I could see signal bars.
After a little research I discovered that my IMEI and S/N number had been changed! Especially, the IMEI number became 350000000000006 (fake one) And I believe this is the reason my signal went off!
So , I just managed to download smart switch from samsung and choose "emergency software recovery and initialization -> device initialization" in an attempt to revert it to stock rom and settings (is this method unroot the phone too?)
But after this long downloading finished , the phone didn't boot , I only see the samsung galagy s6 edge logo stuck!!!!
So , I decided to root the phone again , following the guide here (link-->), zidroid.com/how-to-install-twrp-root-galaxy-s6-edge-on-android-5-1-1/
(in short words , I installed the twrp recovery with odin and I flashed 2 zip files required, from an usb-otg-flash drive, via the twrp recovery install button) and then the phone booted normaly , but the problem with the signal and wrong IMEI was still there!
I feel that I am on dead end , I don't know what to do , I am thinking about sending it to the location I bought it but I am afraid that the warranty is lost.
Please help me restore my phone back to normal
After repeating the whole procedure several times , now my phone does not recognize SIM card at all , as if it was never inserted , wtf?

So you mean that there isn't any way of backing up the IMEI number first before rooting or changing a rom/kernel/recovery to the phone in order not allowing this IMEI bricking happen again by means of restoring from its backup?
I googled a lot and some people suggest that they can backup EFS in some way. What is EFS exactly and how it is related to IMEI?
Also wouldn't be a good idea to find a way to backup my entire OS/firmware (not just IMEI/EFS) before doing anything , in case to save money and avoid the same bricking?
And yes , I have sent the phone to samsung service , it will cost me around 320 euros , because they discovered I changed kernel/rooted the device , and they will change motherboard.
I cannot help the phone without being rooted , I love rooting but I cannot understand why suddenly IMEI got bricked.....does it worth to take risk and root my phone again? But I want IMEI or entire OS backups first before doing that and I don't know how to achieve this without rooting first...
Please help me if you could.
You can backup your full os using twrp recovery
Also your IMEI
In SAMSUNG devices imei number stored in efs partition that's why people asking take efs backup before flashing any Rom

Me too! I have the exact same IEMI number! Mine stopped working after about a month. I tried to return to seller no response. I tried to send phone back they would not accept phone, so it is on it's way back to me. Once I get it back I will try what you did.
I have taken it to factory settings 3 times no luck. I will try your process once I get me phone back.
Thanks!

I did contact one of those fellows a reputable one that can change your IEMI. Well once he heard that crazy IEMI number, he said because it was changed once before to something like he doubted he could change it again and save my phone. To try he charges 100 US plus I have shipping there and back. Yikes.
So any advice you can give me I would truly appreciate.
Thanks!

Mine went down recently with the exact same IMEI and no SN. TWRP was failing to restore the efs partition damaging the files in the process. Long story short, I had to manually extract the efs files, copy them across and fiddle about with permissions but I'm working again.
That nugget rings true - always backup the efs before changing anything.
But for that reputable fellow to say that the IMEI had been changed before because of what it had become, and insinuating that the imei couldn't be changed more than once was complete twaddle. I wouldn't trust him near any of my phones.
On a lighter note I'm sure there's got to be a member on here would sort it for beer tokens
Happened to me, I thought it was faulty ROM and all but then I realized it was simply apn setting. Resetting it to default did the trick. It can be found in Settings > Mobile networks > Access Point Names

Since this thread is quite old and people keep answering , I want to end it like this:
Back then I didn't avoid to pay about 300 euros to replace its motherboard to a samsung shop. But I learned lately that the issue was due to an app called "USB OTG Helper" (https://play.google.com/store/apps/details?id=net.shajul.usbotg&hl=en) which allows you to insert NTFS USB flash drives to your OTG phone but also enables a system partition , including EMS files to be visible.
And you can guess what happened next , I deleted this system partition which this app made it visible and yes , my IMEI was gone!!! After some months , I repeated the same delete thing , but previously I had backed up via TWRP the EFS and MODEM partitions. My phone lost IMEI again , as expected , but after restoring EFS and MODEM , the IMEI was back!!
To sum up , never delete files or partitions that look like "system" like bluetooth and imei folders when you are root AND always have a backup of all your rom via twrp or something else before changing/deleting/flashing anything related to your system.
Hi All,
I wrongly restored the EFS partition from another Poco F1, overwriting the EFS partition for which I don't have the backup.
I know the IMEI numbers of the new phone, so I need only to change the IMEI numbers contained in the old EFS backup to use the right ones (overwritten by wrong backup).
How can I do this?
Thanks in advance,
BR
Update: I found the way to restore original IMEIs, but I got "Out of service" state for the inserted SIM. I used both QPST and QFIL, and baseband seems to be OK but anyway radio is always turned off.
My scope is to restore original capabilities (rebuilding the original EFS?): I bought this phone few days ago, and I can prove it's not stolen sending purchase proof in PM (to a moderator).
Is it possible to fix this?

Unfortunately I can't help you with your request. But if the phone is functional, you could enable ADB and see if erasing modem partitions helps. (It probably won't, but you could give it a try)
Code:
fastboot erase modemst1
fastboot erase modemst2

Thanks for your reply.
I already tried, also with the code *#*#25327337#*#*, but it's still not working.
I also tried to use the QPST backup from the same model phone, that I've, and replacing the IMEI (to restore the original in the broken one) but I got "NO SIGNAL". It seems that the radio is not able to be turned on anymore.
Any other ideas?

I already tried this way too and I got both IMEIs displayed in the OS, but the radio is still turned off.
Actually I found no way to turn the radio on, so I sent the phone to the service center (to be "repaired").
Thanks anyway for your time
Same problem
Hi, I had the same problem with a motherboard I bought from Aliexpress, accidentally screwed with the EFS and now nothing works, tried flashing a QCN with my old IMEIs but that failed as well and I'm pretty much stuck where you are. I can't send my device back because I don't live where I bought it and I wanted to ask if you fixed it.

Got the same problem, even restoring the persist.img didn't help. ANy ideas? Anyone got this working, can't activate SIM card. This is totally a software ISSUE. someone must have this figured out.
