I just rooted my phone and haven't yet flashed any ROMs. Anyway I was told by someone that you should backup your EFS folder (which contains the IMEI) as it can change your IMEI if you flash a lot and you don't get network anymore. Is this true? And if yes, where do I find these EFS files on my memory card?
Thank you
i just rooted and flashed my phone with ARHD rom, nth happened
just do a nandroid backup and everything will be fine?
EFS partitions are a Samsung thing, don't worry about it.

Hi forum,
First of all EFS backup is really REALLY important, do it.
Here is my problem, i wanted to update mahdi rom and wiped cache and data to flash a clean rom. While doing it also formatted system, firmware etc. carelessly.
I have no IMEI right now. I have a backup(not EFS) I did it but it didn't bring my IMEI with it. How can I restore it? or can I restore it? I have been reading topics for hours but I haven't found any solutions yet.
Thanks.
fastboot flash the stock cache.img or restore a Nandroid of the cache.img
Bad format of cache is most common cause of this, not efs on this device

Try to flash the stock rom and see if can solve the problem, however the EFS backup is very important and often you can't restore it without a full nandroid backup..
rootSU was right. It worked which means thunder_bolt96's suggestion also works. Thanks a lot.
Hello,
I'm a Nexus 4 user and recently flashed Lollipop on my phone.
I had rooted my device and was running a SlimKat ROM previously. So before I flashed to 5.0, i made an online nandroid backup of my phone. I then proceeded to download the 5.0 files and flash them to my device. I was not able to just upgrade like some users, so I knew that the flash would erase all of my files. But thats why I made the backup.
In short, I want to know if the Flash erased even my root location (/0) zip backup files. I can be a total idiot and not have realized that after you back up your device, you need to copy the .zip into a different location. Is this the case?
Is there anyway to get my ZIP backups from previous ROM's back?

if you have flashed the factory image on your phone then you lost everything. You must backup your files on a pc before flashing a factory image, unlike an ota update.

So I was just messing around with some ROMs and then suddenly it wouldn't connect to network, so i checked IMEI. And sure enough it's now 0/01. I tried flashing stock firmware with Odin multiple times with no success. I have root and TWRP recovery if that helps, and no backup of EFS.
Maybe someone could send me a backup of their EFS?
Hello friends, first post here. I'm a total beginner and ****ed up my G930F and don't know how to fix it.
Here it is:
1 I have an stock s7,
2 installed twrp via odin but the system entered in a bootloop. just data and formated system, didnt choose any other option.
3 Gave up on the stock ROM. Copied the batman ROM into the internal memory with the phone in twrp.
4 Flashed twrp, everything working pretty fine, but IMEI gone.
5 I dont have efs backup. I Thought that if I did not touch EFS WIPE, i wouldnt have any problems.
Can you give me some help?
Thanks

If you are coming from Thé last Stock rom, you must flash the lastest bootloader and modem by using Odin.
You'll finde bt and modem in Ironman rom thread ?
