After flashing and thinking my EFS was damaged it seems that my network carrier has locked my IMEI
I first flashed MIUI and it worked perfectly, then I flashed LiteStock Rom and I got trouble with modem, I restored EFS and installed a new modem and it worked.
But finally I installed a new rom and I had the sign "Not registered on network". I flashed lots of stock roms and restored EFS, checked my IMEI and SN were the right ones and kept having the same error.
I had another rom of a OMV carrier (Tuenti from Spain) and it worked perfectly.
The thing is that Tuenti uses the same network as my current carrier Movistar, so if the IMEI was locked it wouldn't work with tuenti either.
¿Does anybody know what happens to my Galaxy? ¿Could it be that my carrier locked my IMEI for flashing roms?
Please help, I don't know what to do, my phone works with any other carrier that it is not mine, tested lots of simcards and that is what happens, I also have a friend that had the same problem, he took the phone to a shop to unlock it and he couldn't use the phone because in the shop I think they unlocked it via root and galaxyunlock app.
Blocked IMEI by network is due to theft .
Reads more like wrong modem or CSC see faqs and guides .
Wow, thank you, I did not see any of that about galaxy S3.
Will try that solution! :angel:
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!
g925f imei repair

:good::good::good::good::good::good::good::good:
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.
I've bought it like this and i thought it can be repaired, i had a similar problem with my i9500 a while back and i fixed it by flashing some modem on the right firmware, i don't even know what i had done but it took me 3 full days of trying, truly frustrating. I haven't got the phone's imei as it came without a box or accessories hope you can help me out !
Here is what i've tried so far :
- Flashing 3 different 6.0.1 stock firmwares, none of them worked and after every single flash i would encounter device root key error, i have no idea why but it's easily solvable by flashing some kernel as i've seen on some ytb tutorial.
- Backuped the efs folder from phone root on PC then deleting it from the phone root, restart the phone and proceed with replacing the nv_data.bin and the other similar-named file with the ones i backuped then changing permissions to 1001. <--- This i've seen on some forum, i thought it might help, but it didn't change anything!
I really hope you can help me out, i'm bored of searching the web for answers, most of solution i've found are related to some z3x box or octopus and i believe these cost a lot of money and there is no service in my city that can repair phone's imei
Heloo
Hi i had same problem 920f after flash a wrong rom the only fix is octopus box ...they must rewrite imei it cost me 30 euros!
As i said, there is no such service in my city (I live in Braila, since you're romanian too ), but i'm pretty sure it can be solved without special equipment. I think the owner flashed the 6.0 using odin and spooked when saw fake imei then rushed to sell it. It happened the same to me 2 years ago with a i9500 but i eventually solved it without prior backup.
I have an S6 edge with a glitched IMEI, it is returning 350000000000006 as the IMEI (different to the original IMEI which is shown on the back of the phone). I have tried all of the suggestions I can find for getting the original IMEI back including flashing a stock ROM with ODIN, flashing a stock rom with ODIN while erasing the device's NAND, and trying to fix the IMEI with xposed, but nothing works. It looks like the owner of the phone took it to have it unlocked, and it got flashed with some sort of custom binary, but restoring the device fully to stock didn't help. So I'm not convinced this is a simple EFS partition corruption, and that something might have permanently screwed up the phone's IMEI. Is there anything else I can try to restore the IMEI, or is the phone now as good as useless?
Just curious Shane 2 if you ever made any progress on the Galaxy S6 edge.
I had the same thing happen to me over the weekend. It was very unexpected because the phone is not rooted and I have never flashed anything to the phone. I bought it refurbished on ebay and it has worked flawlessly for 2 and a half years. Then yesterday I got the error 101 the phone has been flashed with unauthorized software & is locked and my IMEI shows 350000000000006. I was about to try and restore the factory ROM, but after reading your post I don't want to risk bricking the phone. Weird thing is it still works with Wi-Fi Calling, it just can't connect to the network.
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?

There was a guide for your problem for my old phone. I don't know if it could help for poco. Maybe it could give some direction.

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.
