[TOOL]Backup/Restore EFS (IMEI) for SGNII

[bodivas]

i lost my imei number...using samsung galaxy note 2 (T-Mo US)...is there anyway to get this phone working again?

Go to the efs folder (with rootexplorer) and tell me how much space do you have?
Likely that you have the corrupt partition..

Nervous new owner

Hi all,
I've had some experience with flashing ROMs/Rooting/Changing various aspects of the Status bar etc to my Note 1.... however, this all seems a bit daunting.
I have recently bought my Note 2 (via Korea) SHV-E250K (N7105) and very gingerly Rooted, Pushed CWM (via Odin) Backed up Via CMW and Titanium.
I still have all functions Messages/ phone calls and data including LTE (in Australia)
I just tried this and it seemed to work well. I have read many times on XDA about people bricking the phone because the used the wrong ROM/Program to restore.
As this seemed to work well the first time was wondering if it is safe to restore this (efs.img) to my particular model or is it only tested on the N71000 models?

Hi
Is it necessary to go back to a stock rom before saving the EFS?
Atm I'm using the Omega 4.1.

Thanks a lot!

if you have a n7100, flash rescue recovery rom, after this if imei don't back, restore efs.img...

Why does the EFS backup using the Windows Tool posted here is 20MB and with TWRP is just 4MB? Is it because it is compressed?

 

[akdenizx]

i have used it on my n7100 device and successfully saved NFS.img

t889?

Will this cover my butt for t889 tmo variant?

 

[dargirisd]

After flashing OMEGA ROM, my IMEI changed and I could not any more connect to any network.
I tried to edit the files in efs folder to revert the IMEI to the original.
That made things worse, as now the phone is in factory mode.
What are my options? (I do not have a backup of efs folder)
