[Q] How to prevent any efs trouble while updating my SII - Galaxy S II Q&A, Help & Troubleshooting

Hi guys,
I've had some troubles with my efs folder last year and I eventually succeed to rescue my device thanks to Helroz app GSII Repair.
I now would like to update my device but I am damn scared to mess with my efs folder, thus I am looking for the best solution back my ass in case of any trouble while updating
I found the programm developed by lyriquidperfection it looks awesome and should allow me to save my efs folder as well as creating a backup (img and tar format)
In case of any trouble is it enough to get back to the working version of my efs folder ?
What about a nandroid backup ? I am note sure if this would be complimentary to EFS pro or if it is doing the same and is then useless while using EFS pro ?
Thanks a lot for ur help. This efs folder is scary, in fact at the time I had not rooted my device and nothing alike, however installing some launcher crap app was enough to nearly make my phone useless !
PS : Here are my device's details :
version : 2.3.5
num version : GINGERBREAD.XWKJ2
modèle : GT-I9100
Kernel : 2.6.35.7-I9100XWKJ2-CL676699 [email protected]#2
Version bande de base : l9100XXKI4
MAJ: PDA:KJ2/PHONE:K14/CSC:KJ1(XEF)

No. /efs contents are phone/imei specific, it wont work for you.

[Q] What`s the most complete backup?

Hi everyone ,im a android user for about 2 years , and i used to have motrola`s and htc`s ,and now i own a goregeous s3 international version,already rooted and runing rom (omega).
I use to help my friends with theyr phone (rooting or updating through odin,etc) but recently ,i received alot of *unrooted* and stock firmware s1 and s2 ,who shared the same problem , after the ota updates (the legit kies way) they had problems with baseband and imei.
And i had a lot of work to do to get them working again ,the s1 was fairly simple but the s2 was a pain in the a** .
While im a pretty monthly flasher ,i was thinking to do a backup of the efs folder for myself (curently i only have a backup of the firmware that was on my phone when i got it a cwm backup).
I don`t know if the efs is in the cwm backup)
If not ,i really want to backup it ,just to sleep well at night ) ,any suggestions how to backup the efs on a s3 ?

Install K-Tool by Hellcat from Google Play and make a backup of th EFS folder or use adb. Look here for adb instructions http://forum.xda-developers.com/showthread.php?t=1689623. After the backup save a copy on the pc.

all you can do now (since you didnt make a nandroid backup of your rom) is to find your firmware/supported custom rom for your device and flash it.
thank for reply

Since you have deleted a system app you cannot boot up your Rom and hence you cannot get access to titanium backup. I would suggest you dont try to flash the roms from other devices as it may cause bootloader issues.
I would suggest you to take your phone to service center and get it repaired.
Btw how did you root your phone ?

hmm i bought it from china market so no servicecenter here, anyways thnx bro, i rooted with "root with restore v17" annd installed pdanet driver n app on pc.

no network,but i have imei

hello guys,i have a s3 ,i installed neat rom with 4.3 and then i had a problem i was conected to the network and when i made a call it didnt work.
i flashed the xxemg4 modem worked then i installed the s4 revolution 9.1 but i had the same problem i installed again the xxemg4 modem but it not works,i flashed then a 4.1.2 firmware with odin,but i had the 00499******00 imei problem i flashed a 4.3 rom i had back my imei,but i can make calls
i made a efs backup,but i cant restore i,its a tar.gz that the neat rom made before flashing,but i cant restore it.so any help guys
thanks for your time
Your emei is stuffed if it starts with 0...
Dont go replacing /efs unless last resort. You need to flash a stock rom in odin. If your on 4.3 now just flash stock 4.3. That should get your emei back. Dont worry about baseband. It can be whatever as long as you have emei. Also check you have an APN as that is often reason for no calls.

Restore the efs backup you took before formatting efs. No backup then you need a better service centre, nothing you can do yourself.
