Hello, my galaxy S is running on generic imei. Currently i am on darkyrom
1. I have efs folder backup,everytime i boot my phone i have to copy that backuped efs folder to the phones folder, and when i do this i get network signals. Once i reboot the phone i have to do all that again. Any solution to get away with doing it everytime?
2. If i get a efs folder of a working imei phone,can i use that to fix mine imei?
3. While flashing few roms, i get this error in cwm
Assert failed 'is_mounted' (efs) .
Why is that?
if you try to flash another NV_data on your SGS you will end up with either No IMEI number or The generic one 004999 bla bla
To get your original back you need to restore the contents of the backed up efs to the efs on the phone.
If that fails, you will need to flash back to an older firmware, froyo worked for me, Some people say eclair. But try and see for yourself.
I have tried to change the IMEI many many times, it just resulted in the generic one. I cant find any help regarding it as it is illegal and no one will comment.
I did try all the methods but failed. Now question is that does having generic imei affect while installing roms? And why do i need to copy paste the efs folder everytime i boot the device :-\
Oh no you shouldnt need to do this on every boot, something is wrong there. Maybe the backup efs is also corrupt.
The generic IMEI can cause apps to not work properly, Market apps to not download, and signal / call / sms issues.
I have generic IMEI on one of my SGS's and its been fine for weeks.
Delete the current nv_data.bin / nv_data.bin.md5 / nv_data.bak and then reboot.
cos my IMEI code is "000....00" now,I have to work on it.
today,I went to the seller which I bought my phone.he helped me and gave me a working phone of I9001 for backup it's efs.I found the below:
1.in efs of I9001,not find nv_data.bin and nv_data.bin.md5.I got the files like the pics show.
2.I backup efs by HC-ktool,then I got a file of 104Mb which it's name is efs.img.
So now I want to know the answers:
a/There are not files of nv_ in I9001,why? how to modify my IMEI?
b/for the getting file of 104Mb,can I restore it into my phone?what's the dangerous(cos hc ktool show me)?
please help !!!! thank you all so much.

Hello,
got the same Problem like alot others. Wrong flashing and the complete EFS was destroyed.
Now i go back to Stock, rebuild the Baseband and the Counter is 0. But still have IMEI NULL/NULL
I read now alot of posts in the Net and tryed a lot but nothing helped.
So my Question is, is there really a solution to build the IMEI back to the Original one if you completly lose the original
EFS Folder? Or do i need to get it to technican to get it back with a Box?
I tryed IMEI Changer App but this one doesnt work on my i8190.
If there is another way to fix this, would be grate to get a but of Help.
Thank you in advance.
So i try to change the IMEI with ALP. But ALP directly gets an Read Error while try to get the IMEI.
Is there a File i can put in and change it with ALP to get back my IMEI?
I had the same problem when i was on my SGY. Just reflash the rom through odin and fix permissions. ??
There is no bad choises, only bad results.
SGS III Mini
tenshi_xp's PAC Rom RC-3
KitKat 4.4.4.
Hi,
thank you for your Answer. But i already reflashed Stock Rom all things are back, i just miss the IMEI File or Area. Saw on the net there are IMEI Folder to flash with ODIN
so i can change it with ALP. But most of the Sites or Files or deleted, maybe false and Viruses, i dont know.
My Problem is that my complete EFS Folder was lost, no Backup nothing. With different Flashes and Stuff i got it back with Baseband, CSC and so on. Just my IMEI tells
me NULL/NULL and ALP cant get it, because this Part isnt available anymore
Can you tell me Stockrom or something i can try? Need something for an open German i8190.
Best Regards

Our IMEI number isn't saved in /efs partition/folder. It's saved in mmcblk0p9 partition which take up to 1MB. The efs partition (/efs>imei folder) only contains the IMEI key code to access the IMEI number in mmcblk0p9 path. If your IMEI key code got wiped and you didn't make a backup of your efs partition, then you will (unfortunately) never see your IMEI again
BTW : Does WiFi, Bluetooth etc. works or not?
EDIT : I found a interesting therad for you http://forum.xda-developers.com/showthread.php?t=2755787. Maybe you can use this efs backup from this user and change the IMEI to your original one.

Yes all other Services are working WiFi and BT. Just the IMEI Numbers are gone.
But if its possible to recreate the Folder and File i think its possible to change the IMEI Number with APS to the old one from the Mobilphone.
But i can get them back if i recover with a OctupsBox or how this boxes are calling?!

There is an alternative method. You can flash this efs.img (which you find in the zip file) with terminal emulator which needs ROOT access.
1. root your device and download terminal emulator from Google play store.
2. Copy the efs.img to your internal storage and open terminal emulator.
3. After open terminal emulator type su to give root access, (your supperuser app asks for root access, confirm with yes)
4. Type/Copy this code : dd if=/storage/sdcard0/efs.img of=/dev/block/mmcblk0p11 in terminal emulator and press "enter"
5. Now your efs partition got overwritten with the efs.img
BEFORE!! you start this method, backup your "current" efs folder by type in terminal emulator : dd if=/dev/block/mmcblk0p11 of=/extSdCard/EFS.img
Please do this at your own risk!

Here the ZIP file. It's not flashable, just unzip it and flash it with terminal emulator
Im sorry but this didnt helped. I think i really need all Parts back to re-partition + Bootloader and all other stuff to get it back.
But i think to send it to a shop to get it back into life.
Many thanks for your Help and merry Christmas and happy new Year

Hi.
I ask for help, as I have IMEI cleared. I tried to reflash the phone, but IMEI is still gone. I noticed there aren't images of NVDATA and NVRAM partitions on any of firmware available online.
Also, wt_custom can't be flashed because of verified boot, haven't noticed any problems caused by it, just saying it if it's important. Raw data of this partition says it has carrier configuration files.
Can it be created by myself? SN Write Tool either doesn't work or I don't know how to use it. Other tool says something about authentication.
I don't know if it's appropriate for this forum, please delete it in case of.
Did you solve that? I have the same problem.
I need the boot partition does anyone has it?
