I got all the bugs worked out thanks alahkel & fughy for testing and of course Amon-Ra for original source.
New link version 2.2.1 Version 2.2.1
New version 3.06 Version 3.06

Thanks to you for the whole great work you've done!
We really appreciate that.

really GREAT WORK !!!!

Please, i need some info, how use adb on P500.

Absolute AWESOME!!!

Thanks!
Thanks !
works like a charm. I have installed your custom recovery. Backed up everything with nandroid, tried KeruROM, flashed back my original branded ROM from nandroid backup.
Everything works. I'm not going to try flash back my original recovery mtd, there is no reason to do it, but have a dd backup just in case. I don't know if it is safe to tamper with recovery mtd, cause I'm not sure if it is re-flashed after every system shutdown. I don't think so, cause I haven't found recovery.img in /system.
I have two questions regarding flashing custom recovery. I haven't used this command:
Code:
# mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak
cause, i didn't found this script on my phone. Is it ok?
Second question: Is it mandatory to copy flash_image to /system/bin with this command?
Code:
cat /sdcard/flash_image > /system/bin/flash_image
Can't we use /data/local/tmp directory and running flash_image from there as we used in the process of rooting the phone? This way we don't have to remount /system in rw and do not have to modify it.
Now I'm going to explore ROM modding ;-)

Flash_image doesn't have to be there but for simplicity I put it there so it would be in ATH. The install-recovery.sh is an evil script that will rewrite a recovery on boot with stock recovery(that only is there on some phones after an official ota update) so rom markers please remove it if it exists.

Any chance the p509 optimus t is similar enough for this to work? I'm willing to be the guinea pig if it should work.

Its close enough it has a very good chance of working but will take a guinea pig to verify. Kernel should be close enough to try. Only differences I saw in the ramdisk of p500 & p509 was model number and lang of en GB and en Us repectively. I had a bad/corrupt dump to work off of on the p509/T. I could use a good dump source with a md5sum to verify its not corrupted in uploading/downloading.
make sure you do this 1st to backup your stock recovery
from terminal or adb shell
Code:
dd if=/dev/mtd/mtd2 of=/sdcard/recovery-dump-T.img bs=4096
please upload that dump for me with a md5 too and I'll work on an official.

Can it be done without root? As normal user?

Thanks of all to drellisdee
I want to advertise that the custon recovery file is no more available at Media fire link that suggest us.
Waiting that the file will be restored is there someone that can upload it???
Thank's of all!!!

Are you just wanting kernel & recovery dumps, because I think I've already changed most other things on my system

Installs, starts off saying E:Bad boot message "
Button layout is correct.
Usb mounting works.
Wipe appears to have worked.
Backup fails with Error:Run 'nandroid-mobile.sh' via adb!

I was looking for just the custom recovery (recovery-RA-GNM-thunderg-1.1.0.img.zip). Now it's available again!!!!
I think that i 've to apply it anyway.
Then if you say that some new rom and kernel are incoming it could be great!!!!
I hope to learn the necessary to help in development ... in this time i accept your works...

[RECOVERY]ZTE V11A/V71A HC3.2 - CWM recovery

So guys.
Here is my humble CWM recovery, tested on 7 inch. Nandroid backup seems to work and flashing also. External SD card is used for reading.
Mounting of card to USB is not working yet.
Colors are now really fixed, including refresh.
Select is also now fixed and short press is working.
I am not responsible if you make some bricks to build yourself a new house. Anyhow chances of bricking are quite low, worst case is that your recovery will not boot and that's it.
I suggest that you make backup of your recovery partition before you start with dd or whatever so that you can flash it back in case something is not ok.
To flash:
Code:
adb reboot bootloader
fastboot flash recovery recovery.img
fastboot reboot
and
Code:
adb reboot recovery
to get to recovery
In the archive is my /device folder if someone wants to play some more.
I got the CM9 ICS booting into Launcher!!!

One more in for future needs.

Great to have mate, thanks a lot for your work.

I'll tell these guys you have a working version for rhe 7",

How can I backup? what do i have to type?
Thanks for your work!

You can make backup for example like this and if something fails you can flash it back directly in fastboot.
Code:
adb shell
su
dd if=/sdcard/boot.img of=/dev/block/mmcblk0p8
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p18

That will actually write img's to the partitions.
Backup is done this way
Code:
dd if=/dev/block/mmcblk0p8 of=/sdcard/boot_backup.img
dd if=/dev/block/mmcblk0p18 of=/sdcard/recovery_backup.img
jakaka you have sources now on utkanos git. You can contact him if you need any help to make backup to internal sdcard work.

Hi, I'm following your guide and the one in http://forum.xda-developers.com/showthread.php?t=1473555&page=1, but I seem to be stuck in the installation of CWM.
I succeded in rooting the Vodafone Smart Tab 10, as busybox tells so.
Then I issued this command:
C:\Users\...\android>fastboot flash recovery v10_cwmrecovery.img
sending 'recovery' (6214 KB)... OKAY
writing 'recovery'... OKAY
Rebooting the tablet in recovery mode always gets me to the Android System Recovery <3e>: wasn't I supposed to be shown the clockworkmod recovery system? If so, what am I doing wrong?
I also tried with Utkanos' v11a version, but with the same result...
Thanks to anyone who will help me

[SOLVED] I solved using the software downloaded from http://wwwen.zte.com.cn/endata/mobile/Italy/, as suggested here http://forum.xda-developers.com/showthread.php?t=1473555&page=59. Moreover, in that same thread (some days around the ones in page 59... ) I found a suggestion about removing some system files to avoid the loading of the stock kernel. I didn't do that, but in case anyone needs it, that could be another solution

Android SDK to Backup my G6-L11

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, ?
HTML:
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.

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 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.

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)

try one of my versions
You can try one of my versions.

persist.img backup and restore

Hey guys! I was doing some forum surfing and I heard about this image called persist.img. I found out that it's specific to each device and you lose widevine if you flash a generic one. So I have 2 questions to ask you guys.
1. If I have a backup of my own persist.img, can I flash it and not lose widevine?
2. How do I actually back up the image?
Thanks on advance guys! ⊂((・▽・))⊃

1. not sure honestly, but I backup anyway to try if it does when time comes.
(Root is needed)
From computer:
adb shell dd if=/dev/block/bootdevice/by-name/persist of=/tmp/persist.img
adb pull /tmp/persist.img persist.img
Or from phone from terminal emulator;
su
dd if=/dev/block/bootdevice/by-name/persist of=/sdcard/persist.img
Make a copy of this to somewhere else(drive/pc etc).
Not completely sure about restoring it, I think you can just flash it via fastboot.

Needs root though.
You could do an msmtool readback i think it's called using msmtool. to backup without root. you do need windows for it though.

Not meant to be rude but...
Code:

Or the one the earlier guy already gave you.
Seems to be the easiest thing you can do either on phone or via adb root shell.
dd is a native command. So if This is not what you're looking for then I have no idea what else does.
