Hi xda,
i bought myself a I9100 with the following Specs:
Android-Version: 2.3.5
PDA: I9100BHKJ1
Phone: I9100XXKI4
CSC: I9100 XEGKJ1
Baseband: I9100XXKI4
Kernel-Version: 2.6.35.7-I9100BHKJ1-CL630390 [email protected] #2
Buildnumber: GINGERBREAD.BHKJ1
PCode: GT-I9100LKAXEG
It has a branding from the German Provider 1&1
I am interested in doing a Backup (nandroid, EFS, Kernel) of my Phone whenever i experience Problems with the Software. Additionally i am (of course) interested in trying new roms or get the soon to come ICS early.
My Problem is, that i cant do that because i have no Download-Source for that Rom to get my Phone back to stock.
So i think the only way would be to Backup the existing Software on the Phone. What would be the right way to do it? I cant flash a rooted Kernel because i will lose my original one. I cant put CWM/Titanium on the Phone without root. And how would i deinstall CWM?
Is there maybe a possibility to use the Guarantee from Samsung directly, when i use another stock Rom?
Help would be highly appreciated.
btw: Merry Christmas and thanks for any Answers
There's a few ways of achieving what you want, but none are guaranteed to keep your warranty, as it's obviously done at your own risk.
You could achieve temp root by using the zergRush exploit. From there you could dump the current kernel, then either flash a kernel which comes with CWM recovery and do a nandroid backup, or dump the whole filesystem without changing kernel at all.
If you're comfortable with adb, see http://forum.xda-developers.com/showthread.php?p=15670403#post15670403 (ignore the part about flashing an insecure kernel, as zergRush should make that part unnecessary).
Thank you for the advice. I think that is what i need to do.
I have to add one more thing (no im not the Ghost of Steve Jobs ). I dont have experience on adb-Shell or Linux in General.
But i would like to try that with your help.
If i did understand it right the way could be:
get root on my stock Kernel with Zergrush
[
How do i get into the Shell?]
Dump all images [Are the command in the mentioned Thread correct? My SGS2 has no SD-Card inside, will that be a problem?]
Alternatively Dump the Kernel only
Install rooted CWM'ed Kernel [How?]
Use Nandroid/Titanium/EFS-Backup
How will i bring all the Images back to the Phone when needed? Respectively the Kernel Only if i used CWM for Backup?
Maybe there exists a detailed howto, because i dont have the maybe needed experience?
I think getting Root with Doomlord/Zergrush is no problem.
When i got root, where exactly i paste the commands shown here (http://forum.xda-developers.com/showthread.php?p=15670403#post15670403)
When i dump the Kernel it will be a rooted dump and i will have to unroot it after putting it back?
How exactly will i have to do the "putting it back" when i need to?
I did not find a Guide (for Noobs like me) or maybe a Tool like HC-kTool (but its for EFS only), that could make things easy. If someone could explain some of these things to me i am willing to learn
How to backup your Phone without Flashing anything by using the Zergrush Exploit
(Now with temp-root method, look at the Bottom)
high chance backups might not work, because the sources are mounted in this guide, doing this i a unmounted state (recovery console from cwm) should work
You need:
Android SDK (to get adb.exe)
Zergrush Doomlord V3 ROOT (Android 2.2 and 2.3)
Zergrush Doomlord V1 UNROOT
Installed Drivers for your Phone
Have all Programs deactivated that use your Device (like Kies)
Your brain, because you do this at your own Risk.
BACKUP your Phone (tested on I9100)
1
Root your Device with Doomlord V3 ROOT following all his hints
http://forum.xda-developers.com/showthread.php?t=1312859
2
Start your command prompt (cmd) and use cd.., dir and cd [Folder] to move to your Folder with adb.exe
type
adb shell [Enter]
su [Enter]
3
Dump the Partitions following all hints from HellcatDroid:
http://forum.xda-developers.com/showthread.php?p=15670403#post15670403
Code:
dd if=/dev/block/mmcblk0p1 of=/sdcard/p1-EFS.img bs=4096

I think it would help everyone if you could make a full backup of your very own device instead of having to download a Rom and Kernel that hopefully fits your device. With this method we leave minimal traces
Without Doomlord (no su etc needed)
I tested the Tip from oinkylicious. It worked!
You dont need Doomlord ROOT and UNROOT for this Procedure (but its the best for permanently rooting your Kernel)
At the Points in my Guide where i use Doomlord, you can use the Zergrush-Method directly. And you dont need the unrooting-step (tested with titanium backup). In addition you dont need the su-command from step 2.
Follow the points here (thanks to paxChristos):
1) Put a fresh (just formatted with no data on it) SD Card into your phone (this helps with some roots, not all, but better safe than sorry)
2) On your phone, goto settings -> applications -> development and check "USB debugging"
3) Plug your phone into your computer
4) Download zergRush
5) unzip zergRush
6) navigate to android sdk (varies from computer to computer, my (win7) install location was c:\Android-SDK-x86 (or something like that)
7) (If you've already downloaded all the sdk tools, you don't need this one) Download and install any missing sdk tools (i.e. adb) (i just selected most of the and let my computer sit overnight to install everything)
8) run command prompt (in windows 7, press windows flag + r to open up the run command, then type cmd, hit enter)
9) Navigate to the "platform-tools" folder inside of your android-sdk folder
10) type in "adb push C:\[location of zergRush]\zergRush /data/local"
11) type in "adb shell"
12) type in chmod 755 /data/local/zergRush
13) type in "/data/local/zergRush"
14) Good luck, it works on some phones, but not others!
Gänsebraten...
I've been watching this thread develop over the past day or so & just wanted to quickly say I reckon you've done a fantastic job with these instructions mate
I know you'll say you had a lot of help (which you did), but initially, you asked the "right" questions (You knew where you wanted to go, but you didn't quite know how to get there, if you know what I mean ?), you persevered and in the space of one day, you've come up with a really useful reference for anyone who wants to backup their phone purely by using Zegrush.
Well done mate. Fantastic job
Hi, thanks
Indeed i had much Help. I think putting some known Information together can bring a new Usefulness. (Just like how our Phones use some Sensors and some Code and some Internet and form something cool like Google Sky Map)
I'm a bit trained in findind Solutions in General due to my Education and Job, which helps a lot. And im reading and collecting Information and Software on the Topic since 2 days.
Currently im trying to find out how to put the Backup back and if it is enough to be prepared (asked HellcatDroid)
I think this could be the simplest way to backup your phone and be independant from Downloads or Tools (ofc. you need Root somehow)
I added a way to flash back the Images. But i gathered it from the Forum and did not test it myself. Anybody can confirm it? Maybe someone tested it?

I notice you went with a permanent root rather than temp root method, which means your backup will also be rooted and thus not stock. If you go for temp root instead (i.e. not pushing busybox, su, superuser) then the backup would be as close as you're likely to get to stock. In case you missed it, I specifically linked you to temp root (http://forum.xda-developers.com/showthread.php?t=1296916) rather than DoomMLoRD's perma-root script (http://forum.xda-developers.com/showthread.php?t=1321582)
thanks oinky, i did not get, that it was a temp root
What exactly makes it temp? Will it unroot when the Phone restarts?
I really missed that point Well i'll test that tomorrow.
Can you confirm my way of "using" the Backup? Will i have 100% of my old status back (except the rooting thing ofc.)? Can i start happy flashing now?
Sorry i have to ask again. Did someone already test flashing the Backups back?
I also would appreciate a confirmation that the restoration via this method works fine.
can anyone confirm this? probably mr. oinkylicious? you seem to me very sagacious.
added the direct use of zergrush in my Guide. now you'll leave even less traces (Although i found no traces with using Doomlord). The Zergrush-File we adb-pushed is gone, too
But one thing we dont know yet:
Will the backups work and be 100% sufficient when done correctly? I'm asking for someone who can confirm or has tested that
Additional Tips i found:
boomsh error at second zergrush:
http://eitwebguru.com/tag/cannot-copy-boomsh-permission-denied/
To fix this issue you have to delete two files i.e. /data/local/tmp/boomsh and /data/local/tmp/sh. Following are the commands to remove the files
E:\ADB\adb.exe shell
$ rm /data/local/tmp/boomsh
$ rm /data/local/tmp/sh
I did a compare (cmp imagefile and directory) and got several problems e.g. "differ byte 1036"
Also i found a thread where someone got Problems with dd

Well as for the guarantee I have bad news for you.
The bad news is that your current backup is useless, if you did a permanent root, not a temporary root, which means that the backup is rooted and therefore not stock.
In that case unroot and make another one.
Besides that I'm curious...
I got my phone from o2 Germany and already had it replaced twice AFTER flashing it.
Does 1&1 have a special branding? What sort of branding do you have? o2 had none and therefore I just flashed a ROM from Intratech's thread before returning it and reset the custom binary counter.

hi sniperfan,
my backup is not useless, just look at my guide where the unroot is implemented. I have now a temp-rooted backup, too.
The Branding is a modified starting-screen, some apps (mail etc.), an own market, starting page in browser.
In Addition i do not find any ROMS/Kernels to download (look at my post 1). There must be a way how the branded ones were created. I would love to see the List to be completed.

Thats the point gänsebraten!
how are the branded ROMs being created? there must be a way to produce them!
how it is achieved and how can we do it?
Yay, lot's of good info in this thread already
Yeah, doing "raw dumps" via "dd" of all(!) partitions is the perfect thing to do, I did that myself before I flashed anything (except the kernel, but for my initial ROM the kernel was available for download).
So you should end up with a bunch of dd images, the ones you really need are:
- mmcblk0p1 => EFS
- mmcblk0p4 => param.lfs (contains the bootscreen and some tiny other bits)
- mmcblk0p5 => kernel
- mmcblk0p8 => modem FW
- mmcblk0p9 => system
- mmcblk0p10 => userdata
Do *NOT* overwrite these onw when restoring:
- mmcplk0p2 and p3 => SBL, bootloaders, don't touch them, just leave them allone, this is the ONE way to really, unrecoverably BRICK the device, breaking these buddies.
What you "can" backup/restore, but don't really need to:
- mmcblk0p7 => cache
- mmcblk0p11 => "internal SD card"
- mmcblk0p12 => some preinstall stuff
To restore something / everything, just reverse the dd command, so if you used
Code:
dd if=/dev/block/mmcblk0p9 of=/sdcard/system.img bs=4096
to dump/backup a partition, use
Code:
dd if=/sdcard/system.img of=/dev/block/mmcblk0p9 bs=4096
to restore it.
Another note on that:
Once you dd'ed the kernel, you should really flash a CWM kernel and then do all the other dd's from recovery mode via ADB.
Reason being: dd'ing a mounted filesystem (i.e. while the system is running and accessing it) can (usually WILL) lead to an unclean/corrupted image that doesn't work properly anymore when restored.

Hey, thanks for your offer. I found a guide for the Alcatel Flame, but I think we are interested in Step 5 only.
Code:
Step 5: Create backup images
Now start shell on the phone using adb shell command and dump backup images to SD card:
$ cat /dev/mtd/mtd0 >/mnt/sdcard/boot.img
$ cat /dev/mtd/mtd1 >/mnt/sdcard/system.img
$ cat /dev/mtd/mtd5 >/mnt/sdcard/userdata.img
$ cat /dev/mtd/mtd7 >/mnt/sdcard/recovery.img
When finished (you may also dump some more MTD partitions if you like), transfer those files to your computer. You may again use ADB for that:
$ mkdir hamachi-backup
$ I="boot.img system.img userdata.img recovery.img"
$ for i in $I; do adb pull /mnt/sdcard/$i hamachi-backup/; done
I can't link yet but it's from Krzysztof Adamski's blog, the full post is titled Alcatel One Touch Fire Hacking (Mini)Guide.
Maybe it would be enough, as the alcatel source for this device is not available yet on their sourceforge page, I'm not sure if it's possible to make a full recovery image without that.
I found another mention of such thing on the b2g-dev mail list
Code:
> You can backup the partitions from a working phone using 'dd' to dump
> them (you can find the relevant devices under /dev/block) and then use
> fastboot to flash them on the bricked phone (provided that fastboot

first of all, i am a total noob..
"Now start shell on the phone using adb shell command"
what does it mean? how can start it?
I'm trying to backup my unrooted Moto G7 phone (android 9) to my windows 10 laptop before I unlock its bootloader and root it. I need the ability to restore either everything or at least the installed apps. For privacy reasons I do not sync with Google.
So, using the command, either
adb backup -all
or
adb backup -apk
I get a popup on the phone to allow the backup, which I do, but the produced file
'Backup.ab' either has 0 bytes or a small number. Certainly not a full backup.
Please help so I can root the phone.
Thank you.
P.S. is there another way to backup an unrooted phone?
Nobody offered to help. So in case someone else is frustrated like me here is what worked for me. Quotations and -f.
Example:
adb backup "-apk -shared -all -f"
works. Note the 2 " and the -f
This also works
adb backup "-apk -shared -all -f E:\path\backup.ab"
I hope this helps someone else.
Backup doesn't start.
Phone: Nexus 5x Android 7.1.2. Phone has not been rooted.
I bought this second hand about eighteen months ago. I know all about the bootloop problem, but this one is OK. I unlocked it and flashed 7.1.2 and it's been as right as rain ever since. However, at the time I didn't relock the boot loader.
I want to lock now, but that will cause it to do a factory reset.
I've downloaded installed the platform tools. (Version: 29.0.1 - June 2019) When I run the command:
Code:
adb backup -apk -shared -all -f D:\Android\20190629.backup
on my Windoze 7 box, the dialog to start the backup pops up on the phone.
The Backup Now button is disabled until I enter a password. This enables the button, but there is no response when I tap it.
Fairly quickly, the command quits, and I am left with a zero sized file on the PC.
One thing that turned up is that it might be necessary to have a desktop backup set in developer options.
I am sure that I have never set one up before. However, I tried this, and it appears to be found by the dialog. However, still no go.
Update: adb backup runs immediately after a reboot.
I have determined that if I follow these steps the backup runs.
Connect through adb
Run
Code:
adb reboot
After the phone comes up, set the correct USB mode (File transfer)
Start adb
Run
Code:
adb devices
Run
Code:
adb backup [I]options[/I] ...
The Backup dialog will pop up on the phone. If necessary, enter your backup password. Tap
Code:
Back up my Data
The backup now runs.
The only thing that I've done differently is the reboot. I've tried this successfully three times now.
I discovered this accidently after installing TWRP. I had to eliminate the possibility that somehow TWRP had shuffled some critical bits, or that the reboot fixed the problem.
