If you have a ubifs type file system on your phone, it is possible to make a backup, but the ubifs blocks must be excluded
see this post http://forum.xda-developers.com/show...&postcount=630
you will need
1 your rooted mediatek
2 Adb drivers installed on pc http://pdanet.co/a/
3 MTKDroid tools http://forum.xda-developers.com/show....php?t=2160490

Mtkdroid tools contains exploits necessary for the rooting process, and this may be detected as a virus by your antivirus program, just temporarily disable your antivirus while downloading, or if you're really paranoid, don't download!
and for flashing
4 SPFlashtool SP_Flash_Tool_v3.1318.104.22.168z
5 Mtk Usb Vcom drivers installed on pcUsb_Vcom_Auto_Installer_v1.1236.00.rar
I assume that you have the necessary drivers installed as that subject is dealt with at length elsewhere in these threads.
Open Droid tools by clicking on the .exe file and connect your rooted switched on phone(with debugging enabled), the application will connect to your device and will show its details. If your device is rooted the colour indicator in the bottom left corner will be yellow, click on the root
button at the bottom
wait for the progress bar and the indicator turns to green and then you have root shell, which is necessary for backup, and will remain in that state until you reboot your device. If the indicator stays yellow, that probably means you don't have busybox installed, you can install it from google play store
Next click on the tab'root,backup,recovery
' and tick the box next to 'backup userdata and cache
' if required, and finally click on backup
, when the tool has finished copying the files, you will then have a complete backup of your device which is saved in the mtkdroid tools backup folder. Note Userdata and Cache may contain your personal data.
Should you need to restore your device to its current state, you can do so by flashing your backup back to your device as follows.
Open droid tools, no need to connect your device to pc, click on tab 'root,backup,recovery
' then click on 'to prepare blocks for Flashtool
then navigate to the folder with your backup file, open the backup file, then select the MD5 file
and click open
the tool will then copy the required files to another folder '!Files_to_Flashtool' which is also inside the backup folder. you can then flash the files to your device with SPFlashtool by selecting the scatterfile in the 'files_to_flashtool folder'
Known bugs: Error when preparing files for FlashTool if in the backup folder there are two scatter files, (normal and PMT). It is necessary to remove one of them from the folder, this will rectify the error.
Thanks to Rua1 for creating this fantastic tool
Never needlessly Download preloader and DSP_BL blocks! It is always dangerous! On some models of phones (for example Alcatel) you will have a brick even if you download these blocks read from your own phone! Always remove ticks in SPFlashtool!!
