Solution for lost IMEI - Galaxy S II General

A while ago I lost my IMEI. I was able to restore it to the developer IMEI 00049...
but could not get my orignal IMEI back. I tried everything I read on my search but since I had no backup of my /efs I had no success.
Now I found a interesting thread on samdroid forum. Somone claim he can repair your corrupt IMEI by sending you a new, correct nv_data.bin. You only have to send him a picture of you original IMEI (on the battery) and 10$.
It seems that he was already successful with repairing IMEI numbers on the SGS.
What do you guys think. Can you trust him? I mean he could use or sell your IMEI for his own purposes. Do you think this will eventually work?
Here is the samdroid thread:

IMEI Unknown, Base-band Unknown, Please Insert SIM card

Hi everyone. I know this problem is well known, and Ive done hours and hours of search online and on XDA but none of the solutions worked or maybe i didnt do it right!
The problem, My friend have flashed a Custom frimware (Litning 6) and lost his IMEI and Baseband some how, they tell Unknown, and now he cant access his SIM or network, the phone doesnt really see the SIM at all.
Ive tried to use Chainfires APK to fix it didnt work, and the Hex stuff really made me dizzy out. didnt know how to use it really.
Ive tried to recover to EFS stuff but i think his EFS is trashed and he didnt back it up..
Tried flashing 2.3.3 stock rom and 2.3.4 no luck. still no baseband or IMEI..
Any suggestions? im out of luck and depressed
Why are you out of luck and depressed if its your friends phone?
If you dont know and understand how to recover these details I would say flash to a stock rom and take phone into a SSC and let them repair it for you.
Same thing happened to me, the phone eventually showed firmware emergency error so I just gave it to samsung service centre, they replaced the logic board etc and got it back 3 weeks later

ill look those links,,, but can i use someones EFS folder to fix this?
Ive checked the links. i think noth bin and .bak files are bad. cuz he already tried messin with them.. XD need new nv_data
you said that he LOST his IMEI.If thats true,and by using a root explorer with root access you can look inside the efs file or mark *#06# and see if nothing comes up,then without a backup theres no way you will get the original back without sending it away to the service centre(personal experience) but when it come back heres a good backup method.Easy as to backup and restore.

Basicly his SGS2 is not even capable of bring a paper weight cuz its too light (100g) lool.. what a bummer... ill try to find a shop to fix it with a box or something,, thanks all!
If you check your nvdata.bin and md5 you will see that, they modified the same day you lost your imei. So you have to return back to those baks and I don't think you can use another device's efs since your imei is hidden in that file.

new solution lounched Fix Repair unknown base banad I9100
Asansam ver 1.6.5 Released
-Fix Repair unknown base banad I9100
Note 1:
we add 3 Solution for this problem after you click Repair unknown baseband and select i9100,procedure start after finishing Solution 1 and phone restart check imei (with *#06#) if solution work you must see your phone imei if you see that you can cLick cancel and enjoy your revived phone if not click on continue and wait until solution 2 finished
do same like after solution 1 (*#06#) work on phone if you get good answer click cancel if not continue for starting last solution if it's not work too,believe me fellas check for hardware fault
Somehow this has happened to my phone, it is not even rooted, I flashed a newer firmware because I'm with bell mobility and they are still on 2.3.3, but that was over a month ago and just yesterday my phone stopped reading my sim card, and the IMEI and baseband are unknown.. I've tried a factory reset and to reflash the firmware, but it is still not working..
Now I cannot find the stock bell mobility firmware either to send it back..
has anyone figured out how to fix this problem? Or what could have caused it in my case?
looks like the service centre is the only option. Best to back up the EFS before tinkering with anything.
my GT-I9100 does this when I let it completely run out of battery power. I've only noticed it since flashing the ICS leaks but this may have been a problem before and I've not noticed.
When I plug the phone into the charger and start it up *#06# IMEI shows as unknown and *#1234# shows unknown modem, I have a small airplane mode symbol and occasionally, a no sim card error.
To fix this I have to let it take a charge for a while with the phone on - then reboot WITHOUT the charger cable plugged in. I probably have some kind of hardware fault but its not that important to me. I have an EFS backup, well I have a few backups here and there
happened to me a few days ago

HELP! Corrupt IMEI, baseband, Serial Numer on S4 I9505

Hi all,
Sorry for the noob question but I have tried most of the repair suggestions in this forum all still could not get back the IMEI, Baseband, and serial number of the handset. Is there a way to program the original IMEI and serial number back into my Galaxy S4 I9505?
The handset had Hong Kong firmware 4.4.2 but with null IMEI, null baseband and wierd serial number. The handset is not IMEI blocked in Australia which I am trying to get it to work.
Would Chimera or Z3x software do this? Kies could not detect the handset for firmware update.
Thanks.

Already tried that. Flashed with stock Hong Kong firmware, modem only, etc and did not fix it.
Is there a way to find out the which is the original firmware for the phone as the previous owner might have flashed it with the wrong firmware?
:crying:
Go here and enter your IMEI. The result should pop up with a great deal of information about your device. Post the result, not including the IMEI itself, and we can figure this out for you.
If your IMEI just disappeared without you doing anything, then chances are you got a hardware failure and the your EMMC chip needs to be replaced.

Hi all,
I have re-flowed the MMC chip successfully. Is there a way to restore the IMEI and baseband without the nv-backup file?
Thanks :crying::crying:
Only if you used Wanam's EFS Backup tool to make a backup. It backs up not just the EFS partition, but the modem partitions and a few other hidden partitions as well. Otherwise you need to use methods we can't discuss on XDA to fix it.

How do I find out the if the modem and IMEI info were still there and not completely erased or gone by the previous owner. I received it with null/null IMEI baseband fault.
You already replaced the modem as it was suggested by someone upthread. That would take care of the modem. There's no way to know whether the IMEI is present or not. It probably isn't present, in which case it needs to be rewritten.

I think the IMEI info is lost so I would need to rewritten as I don't an NV_backup copy
The NV backup isn't present in the /efs folder on Android 4.4.2, at least from what I've witnessed on my own device. That's why I've switched to using Wanam's EFS Backup tool from Samsung Tool as it backs up the hidden modem and EFS partitions where the IMEI actually is stored.
If the IMEI is completely lost, you'll have to take the phone to Samsung for service. As mentioned upthread, there are other methods to fix this, but they can't be discussed here.

Thanks, in my case the modem and IMEI are already corrupted without an EFS backup so how can they be restored except for re-writting the IMEI ? I will look into Wanam's EFS Backup tool to see if I can salvage this mainboard.

Lost my IMEI, IMEI 0000000000 and i did not backup EFS folder. GS4 SHV-E300K Korean

okay so i tried to install xposed framework via recovery since it gave me an error during normal install, the device rebooted the got stuck in a bootloop, i flashed the latest rom for the shv-e300k from sammobile, everything worked great and the device booted into touchwiz, but there was 'No service' and the phone didnt connect to mobile network, when i dial *#06# i get IMEI 0000000000000.
i tried flashing different stock and custom roms, but nothing worked.. i tried a method to restore imei by copying EFS folder and using the .nvdata file, problem is there is not .nvdata in my EFS folder, I even tried installing cyanogenmod 13 and installing xposed framework on it together with the IMEI changer module, I typed my IMEI there but still no service..
PLEASE HELP!!!!!
The NV Data no longer lives in the EFS folder but is located in a hidden partition you cannot access. Wanam Partition Backup could have backed up and restored that partition for you if you had used it, but since you didn't, you'll have to take the phone to a service center and have the service center restore the IMEI.

can you please tell me how to get to that partition using wanam partition backup ? and what is the partiton called ?
All the app does is back up and restore that partition. It doesn't let you access that partition, and besides, it's too late anyway. Your IMEI is gone, and using the app now would only back up what you currently have.
This device needs to be taken to the service center.
same problem here

respected dev. i have the same problem. i flash a different firmware and now my phone baseband is unknown and imei is null. after a few days of checking its still not working. i have recovered its last working condition details as you can see in the photo attached
If restoring stock firmware does not restore the imei, you will probably have to have it fixed by jtag service or repaired using a programming box like an octopus box: http://octopusbox.com
Or have the phone serviced by Samsung, as discussing tools to rewrite IMEI I don't think is permitted on XDA.
I think discussions about restoring the original imei to the original motherboard/phone is okay but discussion about changing imei or serial number to something other than the original is not permitted.
Could you please check this.

check this but before this i want to ask that can i flash other firmware so that i can get baseband back. if i get baseband then i will use the above software to install the New Imei on the Phone. Tomorrow i will try every possible method to get back the phone to life and then if i fail, i will take it to the service center but if there is any possible way that you can help us so please assist and we will appreciate your assistance. thanks Regard Muhammad Ismail
That Xposed module won't work as what it does is spoof the IMEI for apps that have reading or sending the IMEI in their permissions. It does not change the existing IMEI and cannot be used to restore a lost IMEI. It requires the Xposed framework to function in the first place, which should give you a really big clue that this won't work.
If you want to waste the time and try it I'm not going to stop you, but the resolution to the problem requires tools only Samsung has. Android can't rewrite the IMEI as the IMEI is part of the phone's low-level firmware that Android cannot touch.
check your phone box if you have lost the imei

IMEI Unknown on Canadian S4 sgh-i337m

I was having the dreaded "Sim card not detected" message and decided to try replacing the mainboard of my Koodo/Telus S4 SGH-i337m with another from the exact same model but different company.
I rooted the phone (etc) and used the tool at http://forum.xda-developers.com/gal...ool-antaresone-s-imei-backup-restore-t2975136 to do a complete backup of the EFS and stuff
I was able to swap out the boards with no trouble and confirmed the newly repaired phone had an IMEI before doing a restore using the above tool as well, but after doing so, the IMEI says Unknown.
I put the phone into DM mode and enabled cp logging in recovery so the phone could be recognized by Windows (otherwise it was saying USB Device Not Recognized)
I tried Octoplus and it can get the software and firmware info from the phone, but does nothing else. NV Items reader writer gives an "Unknown Command" error for even just reading the full phone.
Not sure what I need to do to fix this. Thinking about contacting an unlocking guy here in Canada who says he can repair the IMEI remotely, but I don't want to do that if it's something simple I'm overlooking. Unfortunately most of the documents talking about IMEI repair refer to options that don't exist in my service menu (for example #6 Common and turning off FTM mode). Would appreciate any help.
The backup method is for the i9505 and I understand that, hardware-wise, the i337m has the same hardware but the major difference is support for LTE frequencies in Canada.
You tried to restore the imei from the original motherboard to the replacement motherboard? Do you have a back up of the replacement motherboard's imei information?
With the s4, I don't think all of the imei information is in the efs folder. Nvdata may be written in a hidden partition.
Yup I took a backup of both before doing anything
The tool I linked to says it supports the i337m and it detected it and did not complain at all.

The tool backed up several partitions it seems, not just the efs.
Just an FYI. Both motherboards are for Canadian models. My original was with Koodo and the new one is from Bell. Both are identical. It shouldn't have a problem with that.
You tried to restore your old imei to the replacement board? Any particular reason this was necessary? Both motherboards were running the same ROM although I'm not sure this makes a difference.
I wanted to keep it as close to the original as possible (guess I'm a bit OCD like that lol) and I'm pretty sure the seller I bought it from on eBay set the imei on it to a fake number, as I checked it online and nobody had any information on it (whereas my original Imei was recognized as coming from an s4).
Did you try flashing a stock rom on the replacement motherboard? If that doesn't restore the imei and you don't have the replacement's original imei, you may be out of luck.
You confirmed that the replacement is an i337m in download mode?
I am trying a stock Bell firmware using odin now and will then restore the imei backup I took of the new motherboard to see what happens.
Trying to restore the imei backup from the Koodo phone may make it worse.
After flashing a stock rom, check to see if wifi and Bluetooth works before trying to restore the imei.

Still working on it, but previous attempts have had absolutely no other issues. Wifi, camera, et al have worked fine.
Okay so I flashed back the Bell stock firmware and my backup of the new motherboard, and the IMEI is back, but I am almost 100% sure it's a fake one. None of the sim unlock methods work and online tools cannot identify it. It's not the old 0049 or any other known fake/invalid one, which is quite weird.
Which method are you using to sim unlock?
I just purchased an unlock code for my original imei and am stuck at this point unless I can figure out why it doesn't work on the new motherboard.
Unlock codes are tied to the imei. Since you can't get your imei into the replacement board, you can't use the unlock code.
Also, some carriers can detect an altered imei and will not activate the phone on their network. Not sure if this is always the case.
We dont support nor allow discussion of imei changing, thread closed.

IMEI Writing I9500

Yesterday I decided to Upgrade my S4 i9500 to 6.0, the rom is amazing (despite the amount of battery it consumes) but when trying to acces to the imei (*#06#) it shows 0049990106..... as you might notice not my imei, I did this EFS.img backup, via terminal but now I am not able to restore it via terminal, I rooted the phone but I just can't do it. i wonder If i can Write the imei via PC or APK since i have it wrote down in my phone bill but obviously now the warranty is totally void... so I have the efs but I can't restore it (it shows succed restoration but nothing happens, no imei change) and i have the IMEI number and i really need help what can I do?
If it were that simple to change the IMEI, then anyone could just borrow a phone from somebody, get the IMEI, and do some mischief with that IMEI.
Did you restore the imei to a stock ROM?

Take the device to a service center and have them fix it. You backed up the EFS partition, but nv_data, which contains the IMEI, is no longer stored there. Thus the IMEI was not backed up, which is why you can't restore it.
