I would like to have a stock backup of the entire rom before I go rooting it just in case I need to bring it back for whatever reason. I know there's a way to do this using the "dd" command, but i'm not sure which "/dev/block/..." i'm supposed to be dumping.
Any help appreciated!
bump.........
I wish someone would answer.. I really wanna go back to stock >_>
a nandroid backup usually helps, but im not sure if that backs up the baseband.
if anyone needs, i have a nandroid backup of my stock bell software.
First off, you have to be already rooted to dump anything.
If you are routed, here's a bunch of dd's I run myself every now and then:
(fire up a local terminal app or do it via ADB)
Code:
su
dd if=/dev/block/mmcblk0p1 of=/sdcard/p1-EFS.img bs=4096
dd if=/dev/block/mmcblk0p2 of=/sdcard/p2-SBL1.img bs=4096
dd if=/dev/block/mmcblk0p3 of=/sdcard/p3-SBL2.img bs=4096
dd if=/dev/block/mmcblk0p4 of=/sdcard/p4-PARAM.img bs=4096
dd if=/dev/block/mmcblk0p5 of=/sdcard/p5-KERNEL.img bs=4096
dd if=/dev/block/mmcblk0p6 of=/sdcard/p6-RECOVERY.img bs=4096
dd if=/dev/block/mmcblk0p7 of=/sdcard/p7-CACHE.img bs=4096
dd if=/dev/block/mmcblk0p8 of=/sdcard/p8-MODEM.img bs=4096
dd if=/dev/block/mmcblk0p9 of=/sdcard/p9-FACTORYFS.img bs=4096
dd if=/dev/block/mmcblk0p10 of=/sdcard/p10-DATAFS.img bs=4096
dd if=/dev/block/mmcblk0p12 of=/sdcard/p12-HIDDEN.img bs=4096
The filenames should give good clues about what is what.
Partition 6 (RECOVERY) can be a bit misleading though, as this partition is UNUSED on the SGS2!
I dump it anyways, can't hurt.
One can argue about how much sense this makes, but IMO it's always good to have a complete as possible dump.
Usually I just go with Nandroid backup from CWM recovery.
FIRMWARE

how can i make sure of it?
go to /dev/block/platform/dw_mmc/by-name - it will show you what partitions you have and where..then read upon how to use dd to make a mirror of all partitions..
example make copy of modem
dd if=/dev/block/mmcblk0p8 of=/mnt/emmc/modem.bin bs=4096
example restore
dd if=/mnt/emmc/modem.bin of=/dev/block/mmcblk0p8
or adapt onandroid to you partition table

[Q] Help to tar my backup rom
Hi to all from Italy.
I've made a copy of my I9100 with this commands in adbshell:
dd if=/dev/block/mmcblk0p10 of=/storage/extSdCard/p10-data bs=4096
dd if=/dev/block/mmcblk0p1 of=/storage/extSdCard/p1-EFS.img bs=4096
dd if=/dev/block/mmcblk0p4 of=/storage/extSdCard/p4-PARAM.img bs=4096
dd if=/dev/block/mmcblk0p5 of=/storage/extSdCard/p5-KERNEL.img bs=4096
dd if=/dev/block/mmcblk0p8 of=/storage/extSdCard/p8-MODEM.img bs=4096
dd if=/dev/block/mmcblk0p9 of=/storage/extSdCard/p9-FACTORYFS.img bs=4096
dd if=/dev/block/mmcblk0p12 of=/storage/extSdCard/p12-HIDDEN.img bs=4096
First question:
If I use bs=4096 the tar.md5 file that I recreate failed the flash procedure !
If I don't use bs=4096 the tar.md5 file that I recreate flash correctly.
May I use this bs=4096 or other value or nothing?
Second question:
I tried only with one extracted file, but what are the correcly order I must use to tar all files extracted and recreate one .tar.md5 file for ODIN?
Thank you

Because I can easy restore all my applications and files best of nandroid backup !
I only use TiBu, it back ups what I REALLY need.
Sent from the little guy
Yes, but TiBu don't backup all like DCIM or other !
And I want backup ALL like a snapshot !

Sorry :crying:
My questions are 2 different for this I've opened 2 threads.
But is ok like this if I wrong !
I know there are loads of software which is hit and miss, and with the recent issue of some peeps having efs borked here is the easy way of backing up your partition.
You will need:
Root
Terminal Emulator (free from play)
Open terminal emulator and enter the following:
Code:
su
then press enter (accept su prompt if shown)
then type
Code:
dd if=/dev/block/mmcblk0p10 of=/sdcard/efs.img bs=4096
EFS.img should now be copied to your internal phone memory so best to copy to your pc
I have tested and it copies fine, using linux internals i have compared the files inside the img against those in efs via root explorer and all are present. I have not tried restoring as well ill wait until the disaster happens before tempting fait
To Restore
Copy the efs.img file to phone memory root not in a folder
Open Terminal Emulator
Enter
Code:
su
Then enter the following
Code:
dd if=/sdcard/efs.img of=/dev/block/mmcblk0p10 bs=4096
Reboot once done
AS ALWAYS
You do this at your own risk , dont blame me if the world blows up
Thanks a lot, very useful.:good:
But could you provide the procedure to restore .... just in case of ........
Very good, there should be an app for this.

Ahem... no
I did it on other phones but i only restore when needed
There's my more easy way,just use rooted explorer to copy the efs folder to your SD,and copy back when U needed.
Did someone have efs backup file for i9205? I really need it. I change IMEI number after restore it.. please..:crying::crying:
I am trying to make backup for EFS because i have htc 10 and i lost my knee so I want to make backup for EFS for lg g5

backup modemst1 and modemst2
adb shell
su
dd if=/dev/block/bootdevice/by-name/modemst1 of=/sdcard/modemst1.img
dd if=/dev/block/bootdevice/by-name/modemst2 of=/sdcard/modemst2.img
but unless you mess with those 2 partitions on purpose.. the EFS should be safe. LG has changed their EFS protection for a few generations now.. it's not like the old lgog/g2/g3 etc.
