Android SDK to Backup my G6-L11

[filipinne13]

Hello everybody,

I'm new user on this forum please forgive me for my english as I am Belgian.

I try to make a backup of my Huawei G6-L11 with Android SDK.

I am on Xbuntu 14.04 (I am not a specialist but I use it for some months). I have installed the packages android-tools-adb and android-tools-fastboot and also android sdk.
My phone is connected to the PC via usb and the debug mode is active.

I followed the next steps in a terminal

[email protected]:~$ adb devices
List of devices attached
68a0f6753968 device

[email protected]:~$ adb backup -apk -shared -all -f backup.ab
Now unlock your device and confirm the backup operation.
[email protected]:~$

The problem is that I unlock the phone but the backup does not begin. Why? What can I do to begin it?

I really need to do this operation as I can not make any upgrade, any changes on my phone as the memory is full

Thanks a lot for your help

Hello,
Thanks for your reply
I have tried with root and it does not function
I followed the steps I saw here https://memo-linux.com/android-utiliser-adb-pour-faire-une-sauvegarde-complete-de-son-smartphone-ou-tablette-sur-pc-sous-gnulinux/
And I can do the first steps, the problem is that the phone is not locked as it should be and the backup does not begin

Other solution?

Thanks a lot

Hello,
I become completely crazy with my problem :silly: I can't do it

I tried a lot of manipulations in order to do the backup and I found something interesting. In a file I had to create in /etc/udev.rules.d/ with the name 51-android.rules, I saw that the product ID seems change every time it is connected/disconnected of the PC. It was 1054, 1037 and also 1051. I suppose it make some trouble... Is it possible to blok it, ?

ATTR{idVendor}=="12d1", ATTR{idProduct}=="1051", MODE=”0666"

Thanks a lot.

Hi!
With the phone ON, with root, plug USB, choose MTP, tuurn ON debug mode, it will pop up a window in phone requesting permissions to connect YOU MUST GIVE IT, need 2GB free in your sd card, use ADB and type this:

adb shell "su -c 'dd if=/dev/block/mmcblk0p4 of=/storage/sdcard1/rpm.img bs=4096; dd if=/dev/block/mmcblk0p5 of=/storage/sdcard1/tz.img bs=4096; dd if=/dev/block/mmcblk0p1 of=/storage/sdcard1/sbl1.img bs=4096; dd if=/dev/block/mmcblk0p11 of=/storage/sdcard1/modem.img bs=4096; dd if=/dev/block/mmcblk0p9 of=/storage/sdcard1/modemst1.img bs=4096; dd if=/dev/block/mmcblk0p10 of=/storage/sdcard1/modemst2.img bs=4096; dd if=/dev/block/mmcblk0p2 of=/storage/sdcard1/sdi.img bs=4096; dd if=/dev/block/mmcblk0p6 of=/storage/sdcard1/aboot.img bs=4096; dd if=/dev/block/mmcblk0p19 of=/storage/sdcard1/recovery.img bs=4096; dd if=/dev/block/mmcblk0p23 of=/storage/sdcard1/system.img bs=4096; dd if=/dev/block/mmcblk0p18 of=/storage/sdcard1/boot.img bs=4096; dd if=/dev/block/mmcblk0p24 of=/storage/sdcard1/userdata.img bs=4096; dd if=/dev/block/mmcblk0p21 of=/storage/sdcard1/cache.img bs=4096; dd if=/dev/block/mmcblk0p20 of=/storage/sdcard1/cust.img bs=4096; dd if=/dev/block/mmcblk0p12 of=/storage/sdcard1/fsg.img bs=4096'"


Now you have your ROM images in sd card. You will need a flash zip to flash it if you need it.
You can use this one, only need to paste the images inside.

Use TWRP to flash it: http://forum.xda-developers.com/ascend-g6/general/twrp-3-0-0-0-g6-lte-devices-t3378495

Hi Persona78,

Thanks a lot for your quick answer
As I understand what you explain in your answer, you proposed me to flash the ROM of the phone but that is not my aim. I only want to make a backup for after try to increase the internal memory. I do not want to root the phone so I found on Internet the ADB program.
I plug the phone which is ON, I plug it with the USB cable, choose MTP transfer protocol, turn it on debug mode and agree with the pop up on the phone. Everything is good until the time when a message should appear to UNLOCK the phone in order to backup. This message does not appear as the phone is already unlocked and as it get blocked, no message appears. Whatever, the backup does not begin!

Thanks a lot.

Hmmm, all apps I know to do backup use root.
You can use CWM or TWRP to backup, but they don't backup cust, and I don't know if recover to images default size.
The only way I know is fashing default ROM.

I have a L11 rom, modify by me, resided and if you create in sd card a primary ext4 partition it wil send the apps to sd card automatically.

Hello Persona78,

The only way I know is fashing default ROM.

Finally, I made a manual backup by drag and drop and also with Mybackup which do not use root.

I have a L11 rom, modify by me, resided and if you create in sd card a primary ext4 partition it wil send the apps to sd card automatically.

I made a reset of the phone with the manufacturer's parameters but I would like to use one other rom as they do not have any update for this model but it seems to be complicated to do it. I do not know how to backup the manufacturer's rom as I met a problem after. I think I would not be possible for me to root, unlock, extend the sd card with Gparted (as I work under UBUNTU 14.04 LTS), and make the update with the new rom, as I am not so talented with computer science.

Thanks a lot.

 

[filipinne13]

I tried and finally I have used Gparted in order to split the sd card. I have now 4 partitions
- swap partition (29 mb),
- fat32 partition (6.35 Gb)
- ext4 partition (23.34Gb)
