[HOWTO] dump your rom

warwolfx0 · Jul 18, 2013

So I have a i9505G that i have rooted
Since there is some difference in some of the phones i though i would post this
Although i have done all this i have not tried to restore this information. and i am only doing this so you can backup you current ROM.

First you will have to find the SD card on your phone
look for it by typing "mount" in the adb shell and look for vfat
most external sdcards are going to be vfat (unless you partition them like for apps2sd)

Code:

rootfs / rootfs ro,relatime 0 0
tmpfs /dev tmpfs rw,nosuid,relatime,mode=755 0 0
devpts /dev/pts devpts rw,relatime,mode=600 0 0
proc /proc proc rw,relatime 0 0
sysfs /sys sysfs rw,relatime 0 0
none /acct cgroup rw,relatime,cpuacct 0 0
tmpfs /mnt/secure tmpfs rw,relatime,mode=700 0 0
tmpfs /mnt/asec tmpfs rw,relatime,mode=755,gid=1000 0 0
tmpfs /mnt/obb tmpfs rw,relatime,mode=755,gid=1000 0 0
none /dev/cpuctl cgroup rw,relatime,cpu 0 0
/dev/block/platform/msm_sdcc.1/by-name/system /system ext4 ro,relatime,data=ordered 0 0
/dev/block/platform/msm_sdcc.1/by-name/userdata /data ext4 rw,nosuid,nodev,noatime,discard,journal_checksum,journal_async_commit,noauto_da_alloc,data=ordered 0 0
/dev/block/platform/msm_sdcc.1/by-name/cache /cache ext4 rw,nosuid,nodev,noatime,discard,journal_checksum,journal_async_commit,noauto_da_alloc,data=ordered 0 0
/dev/block/platform/msm_sdcc.1/by-name/apnhlos /firmware vfat ro,relatime,uid=1000,gid=1000,fmask=0337,dmask=0227,codepage=cp437,iocharset=iso8859-1,shortname=lower,errors=remount-ro 0 0
/dev/block/platform/msm_sdcc.1/by-name/mdm /firmware-mdm vfat ro,relatime,uid=1000,gid=1000,fmask=0337,dmask=0227,codepage=cp437,iocharset=iso8859-1,shortname=lower,errors=remount-ro 0 0
/dev/block/platform/msm_sdcc.1/by-name/efs /efs ext4 rw,nosuid,nodev,noatime,discard,journal_checksum,journal_async_commit,noauto_da_alloc,errors=panic,data=ordered 0 0
/sys/kernel/debug /sys/kernel/debug debugfs rw,relatime 0 0
/data/media /mnt/shell/emulated sdcardfs rw,nosuid,nodev,relatime,uid=1023,gid=1023 0 0
/dev/block/vold/179:33 /storage/extSdCard vfat rw,dirsync,nosuid,nodev,noexec,noatime,nodiratime,uid=1000,gid=1023,fmask=0002,dmask=0002,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0

on my phone the removable card is located /storage/extSdCard

now for the dumping
In adb shell type
su
dd if=/dev/block/platform/msm_sdcc.1/by-name/system of=/storage/extSdCard/system.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/recovery of=/storage/extSdCard/recovery.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/param of=/storage/extSdCard/param.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/boot of=/storage/extSdCard/boot.img

The full dump into a folder called 43dump on the sdcard

Code:

dd if=/dev/block/platform/msm_sdcc.1/by-name/aboot of=/storage/extSdCard/43dump/aboot.img

if you want to dump all the files you can list them by
ls -l /dev/block/platform/msm_sdcc.1/by-name/
This list all the partitions and were they are located

I am not sure but this might work on other phones also
I saw this command while looking at TWRP dev for the recovery on the i9505G
"ls -l /dev/block/platform/msm_sdcc.1/by-name/"
and the dd commands were from "bmbm" on my post from "[HOWTO] Unlocking i9505G bootloader"
i put one and one together and i think this will work.
I am going to try to flash the recovery vi fastboot later to see if the file works, since it should be signed it should work. (fastboot didn't work but dd it back did)

BTW has anyone found a way to turn "secure boot - disable" on the i9505G.

If you have a different' partition table "ls -l /dev/block/platform/msm_sdcc.1/by-name/" then the one I have listed please post it i think there would be alot of dev that could use this info.
I dumped this info into a file on the sd card for reference
su
cd storage/extSdCard
mount >mount.txt
ls -l /dev/block/platform/msm_sdcc.1/by-name/>partition.txt

to flash back a image
dd if=/storage/extSdCard/recovery.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery

would it be possible to do this to the internal SD card? I'm assuming I would just have to change the /storage/extSdCard/ I ask because I currently don't have an external SD card but want to back up the stock 4.3 rom

UlixesTNT · Sep 7, 2013

Hello, what is the difference between this and a nandroid backup executed via ClockworkMod?

Would it work by launching the phone on ADB mode while Android is on? And while ClockworkMod or TWRP are running?

Thank you.

Good stuff (thanked & 5 stars)

Useful regardless of which model you have. If only we saw more threads like this here.

Hi,

Added to FAQ THREAD along with your other i9505G links.

UlixesTNT · Sep 8, 2013

Hi,

I tried to back up the way it is described. To get into the ADB shell I ran CWM. I was able to navigate through the folders and found the once that should be dumped.

I just have a problem. The external sd card doesn't mount automatically when CWM starts and if I try to mount it through the CWM screen it says it can't be mounted.

Any idea about I could work around this problem or how to find the external sd and mount it?

Thank you.

I dont have /dev/block/platform/msm_sdcc*/by-name/ directory, only /by-num/

... on my Xperia J.
I have /dev/block/platform/msm_sdcc.1 and /dev/block/platform/msm_sdcc.3 but I'd like to identify which one is TA.
...sdcc.1 still has 3 partitions on it.
Should I do all of them ?

Second question:
I want make backup using 'dd', I wonder if i can run it directly on phone using busybox's dd.

Raw write image possible ?

How do we get a full Rom dump which will be easier to raw write to a sdcard .?
