hi,
after reading & talking to people regarding changing ROM most of the people recomended backing up the EFS partition (the IMEI)
i have read many tutorials some of them with weird hidden manus that dint match mine #*7284# and actually im getting kind of lost...
can anyone please help me find a guide with an updated on how backup my EFS/IMEI before im trying to mess with my phone?
thanks in advance,
ER
It's just a folder in the root of the device. You can copy it manually using any file manager with root access. Some recoveries such as philz, have an option to backup. There are efs backup apps on play.....

so i have to root my samsung before rom massing to backup IMEI in the EFS?
Yes, but if you want to stay stock no need to back up efs there is slim to nothing chances you will lose imei
Hi, if you want backup /efs folder, don't do a copy folder with root explorer.
Use this app play.google com /store/apps/details?id=net.hellcat.droiddev.ktool

Well if you want to flash custom ROMs you are going to need Root anyway except if you just want to update your current Samsung Firmware. In this case you can just flash via Odin of course without Rooting your device.
Maybe you can backup the EFS Folder via ADB but I never tried that so just pulling it from the system folder via a root explorer is easier, at least for me.

if i understood correctly you flash CWM trough odin and then you can just flash your new rom. am i worng?
and it seems that that guy above you mentioned that copying isn't enough...
so root --> back up all EFS folder (which contains IME) --> flash CWM trough odin --> use CWM to install new rom?

The guy above said that a manual restoring of EFS isn't possible when the phone won't boot into the ROM, well that`s correct but the point of a EFS backup is to restore it when you have a working ROM but without a EFS Folder (happened for some reason more than once here at XDA).
Yes if you have Root, backup your EFS Folder, then you can flash a CWM Recovery through Odin and then after wiping data/cache you can flash a new custom ROM.
first of all thanks for all the help. now at least i can start
so ill just look for goot root tutorial
more of a opinion questions:
so you recommend on using Odin to get CWM? or RomManager ( i heard it can do it)
do you have any rom you can reommend on? or another restore program other then clockwork?

Well it shouldn't really matter but one time I tried to flash CWM through ROM Manager and it failed for some reason leaving me with a bootloop. I don't now what went wrong there but since then I either use Odin to flash CWM or the last time I did it by flashing the Siyah Kernel. It gives you Root and you can flash the CWM Siyah Touch Recovery straight from the S-Tweaks App but it`s really your decision.
About the ROM, there are ROMs that are based on Samsung`s TouchWiz Firmware and ROMs that are based on AOSP / CyanogenMod. There is no such thing as a best ROM, so you are going to have to figure this out yourself since it depends on your personal taste. I use Temasek`s build of CyanogenMod with his Kernel and it gives me the right amount of customization and can be used as a daily driver.

I don't have much ADB experience. So it is possible without actually booting into the ROM to push the EFS Folder into the /system folder?
yes

Unless u want a $400 MP3 player make many and various types of backups.
For ten days i was without a cool phone cuz i rushed ahead and didnt read the guides in their entirety esp the parts on backup-i was so keen to flash a rom and i wrecked my phone and it wasnt easy also worth a read is the pages on how to decypher the code eg where that firmware is from and what modem or csc it has with it

Hi guys. I wanted to go back from cm10.1 to stock 4.1.2 and did a nandroid backup with cwm 6.0.2.7 touch and saved my data also with titanium backup.
After flashing stock JB I couldnt find the titanium backups anymore which I realized are stored on internal card so after wiping everything my data is gone. Ja I know my fault. But then I thought I can just restore the nandroid backup I just made to have everything how it was before, but after doing it my screen stopped at the samsung galaxy s3 screen and didnt boot anymore.
Of course I made the backup with 6.0.2.7 and restored it with th same version, but I dont get why its not booting correctly :S
After that I thought I just root the stock phone and flash cm10.1 and try to restore again but it also didnt help.

CWM doesn't work without root access. Have you tried to install a complete new stock ROM from Sammobile.com? Even though this doesn't recover your data, your phone might work again.

My phone works just fine. The problem is to flash the cm10.1 nandroid backup successful to get my internal sd memory back.
btw I tried to copy the backup to internal sd but then it says md5 sum mismatch god damn it..... I just wanna have my internal sd card files back. grrrrrrrr
If you have Phil's recovery use the aroma file manager to find and move the back up so it can be seen as I'm guessing you are suffering the sd/0/0 etc problem

I guess Im just ****ed... I tried moving it with aroma and then it says error again. its just possible for me to restore the nandroid with cwm which I originally had and just from external sd and even then the logfile says everything is fine just restoring system is an error. that sucks cuz I cant boot the phone then to get access to my internal space via usb
or is there another possibility to restore internal card to get access????
Have you changed recovery versions between creating the backup and trying to restore it?

Yes it does. Recovery and root are completely unrelated. Read the root guides.
Step 1 - flash recovery via odin
Step 2 - flash su zip via recovery
CWM can flash zips, backup and restore without root access to android. Root access is within android only

What's up? Does it not boot? Everything you posted above looks normal so can't advise.
I would recommend updating to latest anyway as 6.0.2.7 hasnt got SDS fix.

No it doesnt boot if I try ro restore the backup I end up seeing Samsung Galaxy S3 screen and thats it....
I just updated to cwm 6.0.3.2 and made a backup and it also showed the above problem but this one restores and boots correctly :S
Another idea is. When I made the first backup with 6.0.2.7 I was also running on yank555 1.6c kernel. Is that important to set up the restore with a running system and this exact kernel? Please tell me what to do if so.

Nandroid backup takes

userdata.img (Your stuff)
Its okay. Somehow I got the data restored with advanced restoring which didnt work with 6.0.2.7 but with 3.2.

Download one of the stock ROMs from Sammobile.com or simply from here and flash it using ODIN. Check this. Remember to download 4.1.2 + ROMs only. Don t flash ICS ROMs as there is a risk of SDS.
Once you flash stock, you will loose your root. So just root again using CF AutoRoot. CF-AutoRoot does not give you custom recovery. So after rooting you will have to install a custom recovery.
PhilZ Recovery is good. Download the .tar.md5 and flash using ODIN same way you flashed the ROM.
NOTE : - Download the versions for your phone model only. Don t download and flash other phone model s ROM/Recovery.

Goto recovery now with your custom ROM, wipe data. Then reboot into download and flash Stock ROM and do as I mentioned.
And yes the backup which you have can be used after gaining root access to restore apps+data using Titanium Backup.
The backups are stored in your SD card. Nothing is deleted from the SD card. But to be on the safer side, just keep a backup of your backups in your computer.
The CM10.1 backup should be in clockworkmod folder in internal/external SD and the apps backup should be there in Titanium Backup folder in internal SD card.
Simply read the how to return to stock for warranty guide

If you don't want to claim any warranty then there is no need to use Triangle Away App...
My Binary Count is 13 and i don't care to reset it.
but if you are returning to stock rom then its always a good idea to reset your binary count.
because if you broke your touch then there is no way to reset your binary count and you wont be able to claim warranty.
believe me it happened to me once.
I always thought that if there is something problem with my phone then i could use triangle away and un-root my phone to claim warranty
but what if touch screen is not working ? Damn no way to reset binary cout

Download HC ktool from the market, create your efs backup with it and use a root explorer to copy it to an external removable micro SD card......

For rooting I will use Framaroot.
For installing CWM I believe that you can install it via ROM Manager, or you can install the ROM directly via Mobile Odin.
Sent from my GT-I9100 using Tapatalk
OK....first....
Why look elsewhere for rooting methods? Everything you need is right here on XDA.
Second.....NEVER use ROM manager on an S2.....it breaks things.
Third....mobile Odin can only be used on rooted devices....primarily for flashing stock firmwares.
What version of android is on your S2....GB, ICS or JB?
This might be my S2, or it might be my W...but it's definitely CM
Yes, I found Framaroot here and am planning to use it for the rooting purposes.
Thanks, good to know. So I will need to install CWM manually I guess. Somehow.
What is it that Mobile Odin does, is it an actual reovery ROM itself or does it install CWM which in turn installs the ROM?
But I can use Mobile Odin to install a custom ROM I think?
I am 4.1.2 JB
Sent from my GT-I9100 using Tapatalk
Mobile Odin is a phone based version of PC Odin.....it is designed to flash back to stock from a rooted modified phone without the need to hook the phone to a PC....
You're on 4.1.2.....
Search for the PhilZ thread.......
With the downloads contained, you can root and flash CWM via the stock recovery in one flash.....don't get much easier than that.......
This might be my S2, or it might be my W...but it's definitely CM
I can root it and flash it in one step? I've found like 50 guides but none of them as simple as you're suggesting.
There are so many ways to do each individual step.
I reckon the steps after that would be to install my custom ROM via CWM via SD card. Clear/Wipe cache and install the custom ROM again?
Sent from my GT-I9100 using Tapatalk
Edit: How can I backup EFS before using the technique you mentioned to root/flash CWM in one go, if my device is not yet rooted?
As I said........easy.....
1) flash PhilZ via stock recovery to root and flash CWM
2) At this stage your phone will still boot normally and allow you to download HC ktool in order to make your EFS backup. It might be an idea to make a full backup (nandroid backup) of your current setup using CWM too....
3) use CWM to flash the ROM (and it's associated gapps package) of your choice.
4) use CWM to perform the cache, dalvik and data wipes.
5) reboot, perform initial setup download user apps.......
Job done.......
This might be my S2, or it might be my W...but it's definitely CM
You could also juse Siyah Kernel, a good alternative to philz:good:
Except that it can't be flashed via the stock recovery.....it has to be flashed via Odin......
This might be my S2, or it might be my W...but it's definitely CM
In which way does a Kernel replace a rooter/bootloader flasher, are these not different things?

I very much appreciate your help Keith. I've been on numerous forum but never got this good feedback.
I searched the PhilZ thread and got so many results. My model is i9100 of the Galaxy S2, I guess the methods you have been describing works for this model?
I need to backup program data and EFS before I dare start playing around.
How can I backup EFS before using the technique you mentioned to root/flash CWM in one go, if my device is not yet rooted?
You can't. And you don't need to unless your phone is rooted, because if your phone is rooted nothing you can do to the phone is capable of borking the EFS/IMEI.
Edit - Also, I'm detecting a lack of knowledge of 'the basics' in the threads you've posted recently; I strongly suggest you read all the guides/tutorials stickied in the thread near the top of the General section before you do anything to your phone. A lack of knowledge exponentially increases the risk of you permanently breaking your phone depending on how little knowledge you have when you attempt to 'do stuff' to the phone.
For backing up the efs you'll need to flash a recovery first (like Philz as already suggested).
But anyway, problems with the efs won't be caused by just rooting so you can go ahead and root first and then use KTool.

Alt 1.) Downloading Mobile Odin to OS. Flashing ROM + GApps via this. But this keeps my stock recovery? (http://forum.xda-developers.com/showthread.php?t=1347899)
Alt 2.) Downloading PhilZ Touch Recovery 3.0 for Galaxy S2 i9100 which flashes + re-roots for me (?). Not sure if it's the right version as the post is old? (http://forum.xda-developers.com/showthread.php?t=1840223)
Alt 3.) Flashing CWM via Mobile Odin, and then in turn boot to recovery (now CWM) and flashing ROM + Gapps via CWM. This should update my recovery as well as my ROM?
After flashing ROM, entering recovery to Wipe Cache, Dalvik and Data
Flash ROM again as previous step supposedly deletes the ROM?
Boot ROM, Configure, Install Apps and restore App Data
Does the above look correct?
Is the version of PhilZ the correct one? It appears to be a 'temporary recovery' rather than a permanent, which might be what I am after if I want to flash the current version of CWM for Galaxy S2 from www.clockwerkmod.com/rommanager
Follow the instructions I gave in this post....

and you will have a rooted phone running a custom ROM. No need to reflash the ROM after the wipes. Wiping cache, dalvik and data will NOT erase the ROM, all it'll do is erase any personal settings and downloaded apps.
Mobile Odin can't be used to flash custom ROMs, I think it can be used to flash CWM.... but only if you can find a compatible version in a .tar format.
PhilZ is still your best bet.....you will root your phone and install CWM in one hit.....all from your existing stock recovery. The CWM inPhilZ is NOT temporary, though it WILL be overwritten when you flash the ROM which will contain it's own permanent version of CWM. Just match your phones build version to the PhilZ kernel that you download.......
Why make extra work for yourself by increasing the number of steps you have to take (use framaroot then try to find a compatible CWM) when you can do it in one step?
And as mentioned before.....DON'T use ROM manager on an S2.....it breaks things....specifically recovery....one of your prime goals.....
This might be my S2, or it might be my W...but it's definitely CM

You could also juse Siyah Kernel, a good alternative to philz:good:

I made big projects of things. As a complete novice within Android, I've read through numerous threads, made project notes, consolidated info and made Mindmaps to understand this.
From my understanding, a kernel (I've seen Siyah mentions on many places) is the interpreter between hardware and the instructions given by the software.
In which way is this comparable to a recovery partition/ROM, namely PhilZ?
I'm sure it's some detail I'm missing, and thanks for the tip.

Thank you once again Keith for your engagement and good tips.
I think the reasons why I am considering the different options, and also trying them out - is to get a broader understanding of Android and the alternative processes as I approach my goal of flashing a new ROM.
1.) So far I installed Framaroot and rooted the device successfully.
2.) I then downloaded Hellcat's kTool and made an EFS backup (and a kernel dump, whatever that is)
3.) Then I installed Titanium Backup and backed up all user + system apps (+data I think)
4.) I then downloaded CWM from www.clockworkmod.com/rommanager > recovery as a zip, booted the stock recovery and started CWM (locally, without replacing stock recovery for some reason), from which I did a full Nandroid backup (with stock recovery intact in this backup, I guess. Device was however rooted so it's not fully original).
I reckon I now just need to download my custom ROM and it's relevant Gapps.
I have read good things about Mobile Odin, and since a while back it supports *.zip files so I believe it is a good alternative for flashing custom ROM's now as well.
PhilZ was a bit intimidating, as there was a general thread and different model based threads in each subforum. They were also in different versions, dates and basebands. Also it appears to be available in a "permanent" download as well as a "temporary", which caused my confusion in the last thread.
I did not know that the recovery was replaced when installing a custom ROM, as I did not know that they contained their own partition of a recovery ROM.
Thanks for the information about not needing to re-flash ROM after the relevant wipes.
Thanks for the discouragement of ROM Manager, I promise to stay away from it.
From my understanding, PhilZ seems to be a modified version of CWM6, which includes ChainFire's Auto Root and some other add-ons as well. Is this a correct understanding?
You don't need to backup system apps/data from Titanium Backup because restoring them on a new rom will definitely cause issues.
Plus in case of a bad flash or something nandroid is always there for you so before doing anything new with the phone always do a nandroid backup.
I'm still on stock I'd like to flash one of 4.4.2 ROMs. However, most of them have line in instructions that latest CWM is required. Since CF-Auto-Root does not contain it, I was wondering if anything can go wrong if I use that root method? Should I proceed with any other root method instead?

If your planning to flash a custom rom straight away you do not need to root (custom roms are already rooted) Flash cwm with odin and well you know the rest about what to do

Hi,
You can use these steps to flash CWM or a recovery of your choice via Odin:

In addition, I personally prefer [i93xx][CWM Advanced Edition] PhilZ Touch.
Hope this helps.

When should I backup EFS? Just after I flash CWM, so before flashing another ROM?

ASAP as far the threads here stipulate. I did 2 backups of my EFS the moment i got my SGS3. I was however, only able to accomplish this by first flashing a custom recovery. Once the custom recovery was installed, (I was and still am using Philz Touch) the first thing I did was backup my EFS folder.

Yep like oreo27 said before flashing any custom roms backup your EFS preferably while you are still on your original rom that your phone came with and make a couple of backups and keep copies on computer.
You will also find that some roms have options to backup your EFS before flashing that particular rom you can never have too many backups ...

The ROM I installed (NeatROM S3) included the option to backup EFS during the Aroma install process, and it's ticked by default. I'm not sure if all ROMs are this good at reminding you
