Hello everyone,
I have an S3 i9300 locked to Orange Dominicana and I've tried all known ways to unlock it and can't get it done! I've tried GalaxSim unlock (after rooted of course) but said that the phone was already unlocked. Tried buying the code on freeunlocks.com and they told me that they can't find the code for my cellphone. And when I flash another ROM, I get corrupt IMEI and can't recover it even when restoring an EFS backup. Only get valid IMEI when the stock ROM is flashed. Could anyone please help me?
Thanks in advance!
Regards,
Ask the phone vendor to unlock .
And when I flash another ROM, I get corrupt IMEI and can't recover it even when restoring an EFS backup. Only get valid IMEI when the stock ROM is flashed.

try to flash official firmware. you can find it here: http://forum.xda-developers.com/showthread.php?t=1075278
help me please.
Never use partition file!!! When you flash phone using ODIN, make sure Re-Partition is OFF!!!
It will delete existing partitions and create new. One of partitions (/efs) contains IMEI code and other unique stuff related to phone. If you didnt backup /efs before flash there is no help, and you should go to Samsung service center.
Agree Samsung service centre as you cannot follow the given instructions .
Tell them it broke after Kies update .

but someone fixed it. go here:http://forum.xda-developers.com/showthread.php?p=17563354
You can either follow the instructions on the restore EFS threads and Fix IMEI threads to see if any work or take the phone to a service centre .
Thats your choice .
Link above says restore your backed up EFS >> HAVE YOU>>
or try flashing original firmware .Have YOU
Or even via the link given in that link .

Their is not a definitive method of restoring IMEI if you have not backed up your EFS some methods work for some but not for others .

Hi, my Imei is corrupted, I flashed a custom rom, and I lost my efs/imei, now my IMEI is 0049..and can't do anything.
My best friend has got the same mobile (Galaxy i9300 s3), and he gave to me his efs folder and a back up, I tried to fix my S3 with it, and it doesn't work, when I reboot the nv_data.bin and md5 are generated by the SO, and they are not the same as I copied from my friend.
I have tried to recover it by all ways, s2 guides, recover your imei in 9 steps..but it does not work.
I also tried stock rom, and it is impossible I cannot get a "normal" imei, always 0049..
Any ideas?I need the phone as soon as possible, that is why I don't want to send it to SAT, here in Spain are 15/20 days for repairing T.T
I hope you can help me, Thanks!
PD: If you are here to say I stolen the phone, please DON'T post anything, because I really need it and I payed for it as you DID! :good:

What rom did you try to flash? I've flashed many many rooms and never had an issue like this.

Do not flash another phone's EFS, it's duplicating IMEI, is illegal and is not allowed on XDA. Even the discussion of it.
If you didn't have a EFS backup for your phone and tried some guides already, there's not much you can do. Send it back to samsung?
Hello,
i have a problem with my I9100G. It has the known IMEI 004999010640000. I want to repair the IMEI back to the original one.
Who can help me with that via teamviewer. The phone also always ask for a network unlock code when the pin of the simcard is entered.
The phone is/was a free one which acceped all cards. But now after the crash it do not accept any card without asking for a network unlock code.
If someone can help me it would be great.
I can also make a payment via paypal if someone help me with success.

First of all, never ever give an IMEI over the Internet, especially your true one. It is enough to mention that your IMEI has been modified. IMEIs can be stolen and in some countries there is a blacklist of them and you risk getting fined or, in some instances, prison.
Now, what ROM are you on? Usually IMEI corruption takes place when you flash custom ROMs. What you should try is flash a stock ROM on your phone. I know my brother has had the issue on his I9000 and he managed to bring back the IMEI by flashing a stock ROM.
If you have a backup of your /efs folder you should restore that. If not, for future reference, you should use Root Explorer or any other file system explorer to backup your folder and have it ready in case **** happens.
Some Kernels, including Siyah Kernel back the folder automatically.

Hi,
I used Android 4.1.2 and CM10.1 - on Samsung Galaxy S II model I9100.
During a phone conversation it was hanged up, and the phone could not connect to the network anymore.
I got an error when tried to manually search for network operator, which lead me, after a research in the net, to find out that the IMEI of the phone is empty. I see also that the Baseband version is 'unknown'.
I have a backup of the efs folder and tried to restore it by manual overwrite it - with no success.
I also followed the guide to recover manually the IMEI from here: http://forum.xda-developers.com/showthread.php?t=1264021 with no success.
I tried to get back to a backup of the original ROM I used before (this time using ODIN), and now I get NULL/NULL in the IMEI and I still get Baseband 'unknown'.
Also re-installing the radio did not help. now when looking for network operator the error is different - now it is telling me that there is no SIM card.
the NULl/NULL IMEI and Baseband version is 'unknown' are still here and I still can't connect to the network.
last input: after 2 days of phone being unused - it suddenly got back to work, the original IMEI got back in, and it connected to the network. this happened without me doing anything, and it held for half a day, then the phone got back to the non-functioning mode as described above, again in the middle of a phone conversation.
I am out of new ideas, all related threads in here did not help.
Can anybody help ?
Does anybody know the reason for this issue?
Can tell what is the thing that is probably corrupted, and in case that the problem is with the files in efs folder - why doesn't a restore of the efs folder (including chown for nv_data.bin to user radio) did not help?
Thanks !

EFS is corrupt.This was a bomb waiting to explode.I suggest you to go back to stock JB 4.1.2 ROM (see my signature),and flash Apolo kernel.Go to recovery and restore backup.Do not overwrite it manually.Do it in Recovery.

Hi GamingDj,
First thanks for the reply.
I want to add more inputs and few questions:
Right now, after more then another day that the phone was not functioning - it got back to operate again, and again, without me doing anything that will cause that to happen.
During the last time that it happened, this held the pone in a working state for about half a day until it hanged up on me during a phone conversation I had - and the phone stopped working again, so I am not very optimistic about the phone getting back to work for good right now....
I have a bit more data that I forgot to mention before:
1. About a day before this problem happened, Avast anti virus offered me to update the Avast Anti theft software, this required root access and I don't know if it has something with the reported problem or not.
2. The efs folder was "handled" by GalaxSim Unlock, after the phone got locked due to official upgrade to JB. Originaly this was an O2 locked phone, then it was unlocked with a code, but due to the upgrade to JB it got SIM locked again and the codes did not work anymore, which caused me to use the GalaxSim Unlock application - that indeed unlocked my phone. I know that the GalaxSim Unlock application changed some data in the nv_data.bin in efs folder, but after it unlocked my phone it was working fine for about a month or more, so I can't tell that this is the cause for the suspected corruption in the efs folder.
I have both backup of the efs folder before and after the unlock operation by GalaxSim unlock application.
Can you explain in more details:
1. Why you suggest to flush Apolo kernel? is it in order to have the phone rooted? can you give a link for this kernel?
2. Restore backup from where? should I have a backup file that you point to? not sure what backups I have that may have data that I don't already use.
3. Does the new data help with debugging this issue?
Thanks again.

Hi,
Just want to update that its been about a week that the phone works without me doing anything, therefore not proceeding with the recovery process you suggested.
I will update if the problem will be back.
Thanks.
Ok so recently I was successful to root my SM-J110F (Vodafone, AUS).
I had found a forum on xda for a custom ROM for SM-J110M.
(link) - https://forum.xda-developers.com/android/software/rom-cleanertlite-os-j1-ace-t3585567
I flashed the ROM using TWRP and it worked.
However sadly, the ROM isn't really that great. The IMEI shows it's "null / null"
so I cannot fix it. The forum hasn't been active so I cannot get a response from the person who made it.
I was wondering if there is any way to fix it and I know I have a custom ROM for SM-J110M but I just want to know if it can be fixed.
Also, since I installed the ROM, the phone says it is a SM-J110M. I was wondering if I could flash in a stock SM-J110M ROM from SamMobile. I tried flashing it using ODIN, but it didn't work.
I really need your help, because I want to stay in 5.1.1. otherwise I'm just going to have to go back to 4.4.4. which is really old.
Problem can be solved and to fix that problem you need manualy to write IMEI and Serial number .
To write IMEI , and S/N you can use Octoplus but Changing IMEI or S/N number which doesn't belong to you is Ilegal so do at your own.
Here is steps for you to follow.
