Well I am not sure where the cert would come from for that but it sounds like the EFS folder got corrupted or deleted somehow.
I know I did that on purpose for a little while to get my galaxy tab 1 to work on a cell phone connection until tmo recognized it as an invalid IMEI I guess.
If you have a backup of that partition somewhere, you should be able to restore that and get it working again.
Flashing the samfirmware would not fix a efs folder issue.
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!
g925f imei repair

repair ok
: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.
Hi every body... This my first participation here and i don't know if it is the right place to share my problem with..
But i hope you help me with it.. So here it is: my friend install a new rom for my sony z2 but i think he did it in a wrong way cause after that there was a message tell me the the software update had failed.. So i didn't know what should i do.. And i tried to fix theat issue using pc comopanion and it seems that fixed the problem until i login after it finished to find out that the phone lost its imei number and i can't enter to my mobile network at all .. ie no signal and mobile not recognize sim card... So how can i fix this damm problem.. ?? i still have imei number on word file if this can help..
And thanks any way
I think your friend should install z2's original rom then it may be fix . Most probably your new rom has bugs so phone does not recognize your sim card .

I used my galaxy mega 2 on AT&T's network for about 4 months without any problems until I decide to root it with either Kingoroot or Kingroot and since then i've been network blocked because it changed my IMEI. I want to change it back to what the sticker under the battery says but have had no luck. So far i've tried flashing it using odin and the z3samsung tool. It was 4.4.4 but now it's 5.1.1 KitKat because I can't try to downgrade because the "repair" firmware 4.4.4 always fails. The bad IMEI 350050500009692 i was told that this imei was a default when your imei gets erased by some mobile tool pro via email. I won't publish the good/true imei that's on the sticker. Baseband G750AUCU3B0H4 , Build number LMY47X. G750AUCU3BOH4. Also I get an error when using the z3tool to write NV data, it says "security damaged". Being the bright person I am I didn't back up anything prior to the first attempt but all I need is the IMEI restored everything else seems to work fine. I'm stumped and need help.
Thanks to all or anyone
