helo,
i am using samsung galaxy s2 GT-i9100
i flashed cm9 before and then i flashed samsung europe stock.
and now i see, my imei number has been changed.
can anyone help me to revert or change imei again!
Problem i am facing:
1.) call , message not allowed. (Gprs is working fine)
when i call, it says error "Mobile network not available"
i think its becuase my imei is changed to some europe imei now.
i want to get my real imei back , to make calls etc.
so, can u suggest me things to do?
did you make any efs backup? if you did then just restore if not... then it will be really difficult... there is few threads about it around somewhere in this forum ( seen it few times ) use search and i wish you good luck
ps. next time install ktool from hellcat and backup efs
Try this http://forum.xda-developers.com/showthread.php?t=1261948&highlight=imei+unknow
hello, somehow my imei got null probably because of rom. I couldn't succeded restoring imei but I know the number so is there a way to write my imei manually ? Thank you.
Google RIFF box. Or you could try flashing some stock roms; sometimes the IMEI disappearing is temporary & flashing stock brings it back. Without a good EFS backup, you won't be fixing this easily yourself.
If flashing stock doesn't bring it back, my advice would be to take it to a local mobile repair shop/someone who knows what they're doing. It will be a lot cheaper than you paying for a RIFF box (that you'll never use again), plus, if you don't know what you're doing, you could bork your phone to the point where you'll need a motherboard replacement if you get it wrong.
Do the smart thing.
Hi All!
I need help from you, because I made a mistake.
The story:
I have 2 Lenovo A660 phone (Phone_A and Phone_B). Both of them were working with full functionality. Once I made a full TWRP backup from Phone_A (NVRAM too) I tried to restore it on the other Phone_B. The restore was successful, but after that I can't use the phone function on the Phone_B: no PIN request, and SIM management item is grey in the Settings menu.
As I think, it is because of the NVRAM restore (IMEI numbers and anything). Yes of course, I don't have a backup from Phone_B before that... :angel:
What I tried to repair:
I restored the original stock ROM (A660_S019_1208024) to the Phone_B and I restored the IMEI numbers and SERIAL (what I found behind the battery) with IMEI&SN Writer V1.5.3. (with the stock ROM's ModemDB and APDB)
...After that the problem still present...
Then I flashed the A660_S025_121122 ROM and I restored the IMEI numbers and SERIAL again.
...After that the problem still present...
I checked the IMEI settings with Mobile Uncle and it seems like good.
I know that, it isn't a simple problem, but I think here are the most experienced people to solve hard problems.
I don't know what I have to do? Do you have any idea?:crying::crying::crying:
Thanks in advance!
by a accident i deleted my EFS file etc. when i was flashing a custom firmware. Then my phone was working correctly except my GSM.
I searched all the internet and i couldn't find a way to take restore my efs. Than i went to a local telephone technical service in my town and he fixed my phone. But i didn't realise he didint use my original imei. I used the phone a several months then suddenly my phone's gsm didint work. So i controlled my imei and it was "004999010640000". And now i need to change my imei number to my original one. How can i do that? i tried "IMEI MAKER/MP0B_001 file method", "MtkDroidTools" and "MauiMETA 3G" and also some other programs. They worked but specially IMEI parts didnt work.
So i need your help. If its a illegal thing. Just PM me. I didint do anything illegal an i need my phone back.
hi my old friend sorry to hear that some technicians used "bluebox" for restore and attach imei. i dont know any idea :/

IMEI is send over your carrier database, they check all IMEIs over network, your IMEI probably was banned because used IMEI number from someones lost or stolen phone
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.
