3) reset the phone, after that, go to the root, and you can see that the EFS folder is still there, don't make any mistake, this EFS folder is new and generated by the android OS.

4) go to EFS folder using root explorer, and delete "nv_data.bin", "nv_data.bin.md5".

excuse me, when i delete my efs folder, and reboot the phone, the generated efs folder only contains :
folder named .files
cryptprop_applied_result
cryptprop_essiv
cryptprop_onetimeboot
cryptprop_securewipedata
folder named dmp


no nv_data files..and a lot of files missing

what I've to do?

thanks

The entire process has been coded into an apk avaible on the market by Helroz
It's called SGSII_repair
It's just saved my phone.

YESSSSSS!!!

YES MAN.


Thank you for this thread!!! I do the points and now i have my normaly IMEI!

I dont have the .nv_data.bin file. When you using the .nv_data.bak and the terminal emulator you can restore the IMEI.

You saved my life!!

I can't access market since my imei is broken.

Tried everything now, and nothing seems to work. My .bak files seems to be fine, but still don't work.
The service center tells me that the only way to fix the imei is to switch the motherboard (which will cost me around 500 USD).

OMG.

You just saved my phone brother.

After installing this, the baseband and IMEI are now back to normal!

Damn. Thanks alot. I owe you and Helroz for this.

What a way to start my morning!

If I've never rooted and don't intend to, do I still have to back up my efs folder?

Can this be done without root?

Without root, You can't access any system folders, nor backup efs files with any tool/apk!

I tried replacing my phone.apk with one that was "the perfect phone.apk". It could be done using root explorer. As soon as I did, I lost signal, and my IMEI no. A factory reset and reflashing VillainROM didn't help.

Luckily I had a backup that I had taken a month back using EFS Pro (Original Development section). I restored with that - but still it didn't show up. It was messed up pretty bad. So I restored and then flashed the stock ROM using ODIN. I then rooted, flashed VillainROM and restored all apps with TB. Saved!

Still, thanks a lot for the helpful guide vaskodogamagmail - I probably will need this one day

Thank you for your reply.
I don't want to root my phone - don't have any need to and don't want the additional tasks of the rooting process.
You've confirmed that I can't backup EFS without root, but if I don't root, is there still a risk of the EFS getting corrupt during a ROM upload?

Thanks!
