How do I backup my existing firmware to my PC - Galaxy S II Q&A, Help & Troubleshooting

Before I change the firmware on my phone. How do I save a copy of my existing stock firmware to my PC please? .... Or is this step not necessary before updating with different firmware? And why?

just create a nand backup, then copy that backup to your computer for safe keeping just in case you need it some time later.
EDIT: or just use titanium backup to backup all user and system data, which will be stored on the SD card and not erased during an update. so you can restore from it to a new firmware and get all your data back.

Problem with creating backup on CWM recovery

Hi all
I have rooted my phone using the SAMSUNG GALAXY S3 TOOLKIT V2.0 by mskip. I have been trying to create a backup of the stock rom on my phone, but when I try to in CWM recovery I get error message "error while making a backup image of / data". Can anyone help me with this or tell me how to make a backup of the stock rom.
Cheers in advance

When you do a backup, the .android_secure folder form the external sd is backed up as .android_secure.img (It's hidden in the backup set and not included in the md5 checksum). This always gets backed up, even in an advanced backup where data is excluded.
Then when you try to do a full_restore from this backup, after it restores /data it attemps to restore .android_secure.img and fails formatting the device, which kicks CWM out of the restore function and back to the main menu.
I've not tried it with the sdcard removed. I didn't know it would fall back to the internal sdcard. Easiest way around the issue (for now) is to erase .android_secure.img from your backup folders.the backup folder will be pushed to thr cwm folder in /data/media internal storage and your phone will reeboot into cwm to restore the nandroid backup...If you use samsung toolkit ; the point n5 is the backup and restore entry ,then passes to the point n10 and performs restore \data\media (internal virtual sd card) if the backup is done correctly you will have no problems ...
Cheers for the advice but I used the complete tool kit and made a back up that way.

[Q] EFS Backup

Hi all,
need to ask a couple of questions regarding the EFS backup.
1) If i use the kTool for EFS backup and do a total wipe before flashing custom ROM, (mounts and storage>format system) will the EFS backup also get wiped out? My common sense tells me yes since the internal SD will be wiped out and kTool saves the EFS files on the internal SD but just want to be sure so that i can search an alternative method for backing up as i want to flash custom ROM with total wipe.
2) Does the EFS Pro app save the EFS backup on the internal SD only or does it have an option to save on ext SD card?
3) Do i just have to be rooted to backup my EFS files? Im just asking as im terribly obsessed my EFS files will get corrupt while rooting the phone! Is there a simple way to backup my EFS files on my ext SD card without root?
4) Can my EFS files really get corrupt just by rooting my phone?
Thanks in advance for any feedback

I know nothing about EFS backup but how about this. I assume you have access to a PC and the usb cable that came with the fone. Or else you do have a microsd card in the fone. Why don't you do the backup and copy the files to either the microsd card or a PC. That way you know you have a backup you can use.
In most cases, and someone can correct me if I'm wrong, the format system will not touch your backups.

Yes very true, i can also do that and it also crossed my mind but im afraid that by doing so, copying the EFS files and folders onto a PC or directly to the ext SD card will alter the files and folders in a way that they cannot be restored and i dont want to take that risk unless im totally sure of what im doing or if this can actually be done.
Thanks just the same for ur feedback
Ok so I just found out that with EFS Pro I can backup on my pc safely. Do I need to be rooted to use this app and safely backup the efs files?
Thanks

[Q] recover voice recording files by restoring in CWM??

Hi I recently install CM 10.1, I backup my personal files and also made backup via CWM after this I install CM and erase everything I wanted to have a clean start, after doing this I remember, i did not backup my voice recordings they were in the "sound" folder, if i restore the CWM backup is possible to recover this files????
Greetings!
Sorry no as these are on your SD card you deleted. Cwm bk up saves data not SD card. Personal files you bk up was sound file no?
The "sound" folder was in the internal sd saddly i never backup that folder. I already try to restore with out succes it says error during the restore, but i guess im trying to restore something will not get my precious files back

TWRP backup on pc?

Hey guys I wonder if it is possible to save twrp backup of a rom in a pc in order to get more free on sd or internal!
Just transfer the backup on PC. If you want to restore your backup then transfer it back on your phone.

backups beyond nandroid

As we know, a twrp nandroid does not backup user data. So to be safe, that needs to be backed up separately. Even Titanium Backup does not backup documents, DCIM folders, etc.
I am not an android expert but I guess that all the data that is not included in a nandroid backup probably lies in a separate partition on the phone. If I am correct, rather than backing up these individual folders is it possible, on a rooted phone, to simply backup that entire user partition to a usb device in one go that ensures everything can be restored?
How?
Thanks.

User data is stored in the /data/media partition.
When creating a nandroid backup, you can choose the option to include "internal storage", this will backup your user data. Restoring this backup will restore your user data along with your ROM.
Other methods are:
Connect your device to PC via USB, then open the devices storage on PC then highlight all the folders and files that you see there and copy them then paste them to a folder on your PC. This will save all of your user data, to restore the data, connect to PC and copy everything back over to your devices internal storage.
You can also use "adb backup" to back up and restore user data.
