Hey guys.
Im new here.
I have a S3 I9305 and i looked in the forum and found this thread about backing up the " ESF/IMEI " thing before doing anything else ( Root, Flash....).
Can someone explain me what are these and WHY should i do this?
Thanks in advance.
EFS folder contains your imei and may be corrupted during flashing. If it is, and you don't have a backup, you won't be able to use your phone's antenna, meaning no calls, sms, data.
yeah glebun is correct. id always recommend backing up your EFS even if not currently changing your rom
EFS does not contain IMEI on the I9305.

Get Odin KK4 with bootloaders and that should fix your IMEI problem. One it's fixed, make a backup of your efs folder so that of it happens again, you can just replace the new folder with your backup one.

Well if you have folder named backup in your internal sdcard then you are still in luck but if you don't have and flashing that firmware didn't did anything then I ma afraid my friend you now have a good mp4 player which can also run android games and apps

Odin KK4 with bootloaders: Use the search function on the forum, I know it's here but can't look for it at work.
Backup efs folder: Open ES File Explorer (free on the android market), browse to the folder, copy it, put it somewhere safe.
Not many more details then that :good:
I've seen IMEI messages about no emergency calls when upgrading to Jellybean but would their be any problem with changing from one Jellybean romantic to another.
You may have lost your IMEI. Search XDA how to restore it.

I'm fine just bought a Captivate from Swappa with CyanogenMod, but want to put Pac Man Rom on it and was wondering if I would have IMEI trouble or not seeing how it's already on Jellybean.
Lost IMEI during upgrade process is a random occurrence.
OK thanks I'll just make a backup just in case.

Okay so I was flashing a couple of different roms on my s3 mini (GT-I8190L) and I guess I screwed it up and did not make a backup of any sort and now my phone will not recognize my sim and has an unknown imei and baseband. Is it possible to fix this? Any help is highly appreciated. Thanks in advance.

You can find it here. Click on i8190, i8190L or i8190N. Depends on which version you're using.
