How to dump system and boot from a standard device

57 posts in this topic

Posted (edited)

I have written a full how to dump system and boot partition.

The goal is to keep your device as untouched as possible and to be able to provide the dump.

It is specially usefull if you have a new devices for wich we don't have the dump. So please dump you system if your are this one.

First of all i don't advice you to install lastest sdk because adb tools where updated for froyo and can have problems to access device. That's why i provide you an archive with adb in it.

I) Before device (preparing operation)

===========

1) install acer drivers : http://www.megaupload.com/?d=E5PTHL3O (reboot the computer to be sure they are isntalled)

2) download this archive (in next step i will call it superboot.zip)

http://acer-liquid-community-rom-bugtracke...s/Superboot.zip

3) Extract the content of Superboot.zip to a directory, let's say c:\superboot.

4) Copy adb-windows.exe to adb.exe (copy not move) IMPORTANT. To be clear you can even rename adb-windows.exe to adb.exe or duplicate the adb-windows.exe file and rename the duplicate file to adb.exe

5) Download this archive http://www.4shared.com/file/-0yByOIb/mzTools.html

6) Extract the content of mzTools.zip in the same directory as the content of superboot.zip

7) Test can you can use adb :

7a) open a terminal emulator ( start / execute / cmd )

7b) move to the directory where you have stored tools using cd command (for exemple cd \superboot)

7c) adb devices -> should return "List of devices attached" and nothing more.

7d) you adb installation is ready

II) When you have the device (dumping)

================

1) Go in Settings / About Phone and note all informations provided

2) Go in Settings / Applications / Developement and enable USB debuging (without this will not be able to do nothing)

3) Connect the phone to usb

Connecting to the device

4a)open a terminal emulator ( start / execute / cmd ) From now : all operation must be done in the terminal emulator

4b) move to the directory where you have stored tools using cd command (for exemple cd \superboot)

4c) adb devices -> should return "List of devices attached" and a device with a number (that is your phone)

Dumping system content

5) adb root

5) adb push busybox /data/local/tmp/

6) adb shell chmod 777 /data/local/tmp/busybox

7) adb shell /data/local/tmp/busybox tar czvf /sdcard/liquidEsystem.tgz /system

Dumping boot content (does not always work)

need to be completed to gain root access

8) adb root

8a) adb push dump_image /data/local/tmp/

9) adb shell chmod 777 /data/local/tmp/dump_image

10) adb shell /data/local/tmp/dump_image boot /sdcard/liquidEboot.img

Getting files

11) adb pull /sdcard/liquidEsystem.tgz . (will take a long time)

12) adb pull /sdcard/liquidEboot.img .

Files will be in your superboot directory

Cleaning all traces of operation on your phone

13) adb shell rm /data/local/tmp/dump_image

14) adb shell rm /data/local/tmp/busybox

15) adb shell rm /sdcard/liquidEsystem.tgz

16) adb shell rm /sdcard/liquidEboot.img

Disable usb debugging. You phone is the same as out of box.

Provide us

liquidEsystem.tgz and liquidEboot.img files

4) Copy adb-windows.exe to adb.exe (copy not move) IMPORTANT

Do you mean rename or what?

I'm trying to translate this instruction to Russian and I'm not sure I understand it right.

Rename will have 1 copy in the end (like move), copy will have original 'adb-windows.exe' and new 'adb.exe'

I think the intent is to remove '/sdcard/liquidEsystem.tgz' afterwards. The extra '.' is where the error is from, not sure if it's really needed or a typo.

If you look at the baseband you notice it's older than the one we have.

We have: 04.02.XX, this have 04.01.01

Yep,i've seen that but we can't jump to any conclusion until our developers get their hand on it.So far we can only see two different Baseband version but is hard to say wich on is older (not always newer =better).

Btw now that Acer is selling a product with Eclair on it they should release the source,right?

I guess they use the "Liquid E" just for the commercial brand....pointing out that is using Eclair.
