here are the options for backing up / restoring efs (this list is not exhaustive)
EFS Pro - App needs root
SGSIII EFS backup / Restore - app runs from Windows / Linux and needs root
kTool - app needs root.
Philz advanced CWM rewcovery - custom recovery can take efs backups using the "Custom Backup" feature.

I would recommend PhilZ recovery......

[Q] Can anybody help me ! ?

hey guys.. am still new to the world of ANDROID.. so i need some help please..
i wanted to update my GB Samsung Galaxy SII rom to the ICS rom.. so i wanted to start by rooting..
i rooted my phone and everything went okay and i also removed the Yellow Triangle..
my problem is.. now i want to flash a new rom to my S2..
i booted into recovery mode..
1st problem is that i didn't find a "Backup & Recovery" option as i saw in many videos..
the main problem is that i wiped the cash and the user data
but when i clicked on apply * from sdcard !!
and choosed the rom i've downloaded.. it didn't work.. i had an error saying that E: Signature Verification Failed
so.. and when i wanted to do a recovery using the CWM app.. i didn't find the backup and recovery option
if you have acsess to download mode, then reroot your phone, then you will gain acsess again to recovery & backup.

Sorry, I didn't express myself correctly. I meant you can reflash a stock unrooted firmware (kernel, rom) and then root it again.
okay guys.. am so sorry for the mistake i've made.. my probles was that i was going to the reboot mode using the cwm.. not the up-home-power buttons..
i told you am still new .. i thought they are the same .. anyway...
i recovered the rom with all the apps and everything is okay now.. but
the question is why i can't flash that rom ?? .. even with the right recovery mod it's still doesn't want to be flashed. ??
could it be because of the version of the rom ! ??
and is there a way to know what rom can i flash ??
and i also have a problem.. it's that the samsung kies isn't supporting my device.. i used it once and after rooting my cell it doesnt want to work again.. ??

First off you don't need to be rooted to up grade your firmware. The best source for firmwares is Samfirmware.com where you download a tar. file then flash it in the PDA section of odin. Please read the sticky threads in this forum as there is loads of good advice and guides from expert users. All the best.

Thankss
Thank you all guys.. i flashed the ICS 4.0.4 firmware to my Galaxy S2 I9100.. and everything is okay..
now i am wondering how to root it ?
is it the same way for the GB?
actually i tried the same way but when i flashed the CF Root --LPH my phone died !! .. i mean it begin restarting every time i turn it on..
my Baseband version is I9100XXLQ6
and the kernal version is I900JPLPH
please send me a link that works..
There are a couple of methods to root. If you only want to root and not bother with custom ROMs, kernels and the like, use Rachmat3's temporary cwm to get root. Search for it.
If you wanna install custom ROMs, you could install a the TAR version of a custom kernel like siyah or dorimanx via Odin. Steps on how to do so can again be found with a simple search.

This should do,
1) Backup everything
2) Install Siyah Kernel (latest: http://www.gokhanmoral.com/?p=1536) using Odin (tar file)
3) Now you are rooted with Siyah Kernel and a CWM based recovery
4) You can then install any ROM/Kernel of your choice (if you need)
But "Search" - There are countless threads
thanks alooott
i really dunno how to thank you guys.. everything is working now as i want it to be.. thank you all guys ..
if i need some more advanced help who should i ask.. things more like programming
because,
i am 3rd year student and i am studying Communication and Computer Networks engineering.. and i am thinking about doing a programing project..
so if any one can help me.. i'll be so thankful ..
again thank you all guys
Do you have disabled the signature verification in recovery before flashing the rom?? Try this and see...

First backup your efs and yes you can flash stock 4.1.2... but after flashing you won't have any network, then you should restore your efs.. And everything would be good to go.. Backup and Restoring can be done by Phils recovery or ktool from play store...

Mmm don't know much about that method.
What recovery are you using? Make sure the files you downloaded are not corrupt also make sure you are using a custom recovery (not stock recovery) also make sure you are definitely rooted these are common reasons for Signature Verification Failed
I recommend
(1) Flashing stock 4.3
(2) Rooting with CF-Auto-Root
(3) Flash Custom recovery Cwm,Twrp,PhilZ
then flash your patched files......
If not work service repair.....

The patched files don't fix wrong imei they only allow you to get a network signal by allowing your efs to read your modem thus giving you a signal. If they don't work then I suggest service repair.

friend.
for gt-7100 is correct this twrp-2.8.6.0-t03g.img.tar.
caution - twrp-2.8.6.0-t03gub.img.tar, twrp-2.8.6.0-t03gduoszn.img.tar, are other devices
size > 8MB, beyond the incompatibility and lost partition EFS, now recovery using stock rom .
Messed up with dev/block and efs !
Download stock rom for n7100 from samsung's official site.
Flash stock rom using odin.
This will reset your modem/radio (lost IMEI) and efs folder.

I know the feeling...i avoid all the TWRP updates and keep only the version 2.7.2.1, with this one i have no problems at all. The version 2.8.5 worked well...but after my 3rd ou 4th flash/reflash ROM i lost the Mobile Network...and yes, im pretty sure that was caused by the recovery.
After fix the mobile network problems, i reversed to TWRP 2.7.2.1...flash, reflash and flas again the same ROM and its all working fine.
I never had any problems with CWM..but TWRP make F2FS easy to implement on nandroid, thats why i keep using it.
I Just get the Mobile Netwok back, after flashing oficial Sammy ROM with desktop Odin.

Applied twrp-2.8.0.0-l900.img and modem.bin
To clarify my issue (same as OP): Applying twrp-2.8.6 seems to have ganked my modem. Everything else works. I tried MULTIPLE times to restore to factory, then apply twrp then restore from backup. Found out it is only happening AFTER I apply twrp 2.8.6. I finally found a copy of twrp 2.8.5 for the L900 but that has the same issue, so I applied 2.8.0 and the modem bin at the same time. This seems to have fixed the radio and i am back to functionality AND twrp is installed.
Now, I am not POSITIVE that it requires both actions (it might just be an issue with 2.8.5 and 2.8.6), but the solution was:
Code:
heimdall flash --RECOVERY twrp-2.8.0.0-l900.img --RADIO ./ALL_SPT_L900VPUCNE2_L900SPTCNE2_1561791_REV04_user_low_ship/modem.bin --no-reboot
If I have to do this again, I would apply twrp-2.8.0.0-l900.img first using your loader of choice (Odin3 or heimdall et al.) and see if that was all that was necessary or they both have to be applied (for some wildly cool magics that I am sure no one would be able to figure out).
