IMEI Writing I9500 - Galaxy S 4 Q&A, Help & Troubleshooting

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.

[Q] IMEI is 0 (zero)

I bought a rooted G2 from ebay. My IMEI is 0 (Setting>About Phone>Status). I suppose it got lost during rooting. Is there a way to restore it?
1. The sticker on the battery cover still has IMEI number. Can I somehow write it back?
2. The phone has clockworkmod directory and has .recovery_version file in it. Can this be used somehow for the restoration purpose?
3. Android 4.4.2, kernel 3.4.0, software version D80020c, Build KOT49I.C80020c, Baseband version M8974A-AAAANAZM-1.0.190082. Is this LG ROM?
4. I am still connected to network somehow.
Thanks.

Usualy to fix this you need to have an efs backup of your imei but you probably don't as from what I understand, you recieved the phone without the imei.
try to go back to completely stock: http://forum.xda-developers.com/showthread.php?t=2432476
if you manage to get back your imei that way, you'll easily be able to root your phone again and this time around make if the imei shows up, you can make an efs backup so that if it ever happens again you can always restore your imei through the efs backup. (you can google how to make an efs backup.)
but start of by going back to stock and let us know if it worked.

I read the linked procedure. It is a very scary-looking one. Honestly speaking, I am afraid of screwing the phone up majorly. (All my pc's are ubuntu (linux) except a Vista laptop)
The phone is working, 4G LTE data, voice, texting, one app from google play. What is the likelihood of losing these all of a sudden because IMEI=0? Would you still recommend to get IMEI straight in the first place?
Thanks.
PS: I just talked to Cricket Wireless, my service provider. According to the rep, I will not lose connection all of a sudden just because my IMEI is 0. Can I trust this semi-technical person?

That's your call. If everything works and you're satisfied, then let it be. That was the only solution I could come to think of. By following the tutorial to the dot, you can't go wrong. But if you're uncomfortable, I'll say let it be.

Send it back to LG for repair. messing with the IMEI is illegal (short of backing up and restoring) and as such banned from the site.

and i find it lost imei & baseband, GPS not working too, but wifi & bluetooth is ok.

No, under absolutely no circumstances should anyone give to you their EFS information/backup. It's illegal for a start. You should have made a backup of your EFS, you're going to have to send it for repair.
^^This, exactly.

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

Restoring IMEI after generic IMEI 0049...

Hello.
I'll first describe the secuence of events and then tell which solutions I've tried. Bear with me. I'll be brief.
I've bought a second hand Samsung Galaxy S4 (i9500) sold through a local carrier. By law the carrier can only give the unlock code to the original buyer of the phone, and the person from who I bought it from wasn't him/her.
I tried to unlock it by my means (basically this, trying lots of variants until "186" code dead-end), which resulted in rooting, flashing diferent modems and trying a CM based custom ROM (GearCM). Before going on any of this, I made an EFS, cdma-radio, radio, m9kefs1/2/3 backup.
As I couldn't do it, I took the phone to a repair shop, where they unlocked it with a box. Then they told me that the SIM tray was broken, and after trying a different one, they concluded that it was a software problem (I suggested it) and flashed a stock ROM from the carrier, which still didn't recognized any SIM.
This is when I took back the phone.
I've restored the EFS and flashed the correct modem (In fact I've found two which work: I9500UBUHPB2-CP and I9500UBUHOI1), but even if the SIM card is recognized, I can't connect to the network, I think, because the IMEI which displays the phone is different from the factory IMEI. In fact, is the infamous generic IMEI 0049... with IMEISV 01.
I've since tried this methods:
- Changing permissions of the EFS folder
- Flashing the stock ROM after completly wiping out the phone
- Manually deleting the EFS contents and restoring
And combinations of the above with RegionLockAway and with both working modem drivers.
I still have to try rooting an older stock ROM, maybe 4.4.2, but I wanted to ask more wise people if there is a logical, correct order to any of the above steps, or if you think I'm missing something here.
The only other answer that comes to me is that it's something done by the repair shop with the box, but still I've no conclusive proofs of that. I wanted to exhaust options.
Thanks in advance. Any answer will do good.
Restoring the EFS does nothing, as the IMEI is no longer stored in it. Thus none of the things you tried will help. You'll have to take the device back to the place who fixed it for you.

I would have thought that it was stored on it. Do you infer that from my failed attemps? Where should it be "stored"?
I don't "infer" anything. It's a fact. IMEI was stored in a file named nv_data.bin in EFS, but for some time now it's no longer been located there. It's been moved to three hidden partitions that a nandroid backup does not touch. You'd have to use Wanam Partition Backup and Restore to see the partitions in order to be able to back them up as well as restore them. Thus, your IMEI is gone, and the repair shop is going to have to fix it.

But I have a backup of those partitions, made with Wanam Partition Backup. I've restored them in this order: cdma-radio, EFS, radio, m9kefs1, m9kefs2, m9kefs3. Somehow, its not working.
That's why I think maybe it has to do with the order of the steps I'm taking, maybe even before restoring the partitions.
I edited my post while you were making yours.
My backup consists of much more than those three partitions. I have in addition to those efs.img, fsg.img, modemst1.img, and modemst2.img. The IMEI is in one of those partitions, NOT EFS.
Well then... I hope they can repair the IMEI then. It would be a damn shame if not... Thanks for your time.
