Requirement

* PC
* Rooted Spreadtrum phone with sufficient SD card storage space
* Install Spreadtrum drivers on PC using this guide @ http://forum.hovatek.com/thread-827.html
* Setup ADB on the PC using this guide @ http://forum.hovatek.com/thread-588.html 
* Enable ADB detect the Spreadtrum phone using this guide @ https://forum.hovatek.com/thread-2137.html 
* Install Busybox (Stericson) on the phone


Procedure

* Download BackupTools.tar and copy it to the same directory as adb.exe
* Launch ADB, type the commands below and press enter after each command

Code:
adb push backuptools.tar /data/local/tmp
adb shell
su -c mount -o rw,remount rootfs /
su -c "tar -xvpf /data/local/tmp/backuptools.tar"
su -c "./mkbackup.sh"

* x means extract ; v means list files as extracted ; f means the name of the archive (file to be extracted) appears next ; p means retain permission 

All partitions on the phone will be saved to the backup directory on the phone's memory card

Error messages and fixes

* If you get  "User unallowed: Operation not permitted" in ADB then go to the phone and set ADB to Allow in the Super user application (the name might vary depending on your rooting method)
* If you get "tar: can't remove old file ***: read-only file system" then ensure to run the remount command above properly
* If you get "sh: applet not found" then install Busybox Installer (Jrummy) instead of Busybox (Stericson)
This method is not working. think some steps are missing, I was trying it on my LYF LS-4005 handset having sc8830 chipset.
how much time it will take to backup?
where the backup will be saved i.e. in root folder or in a specified folder??
Plese explain all the steps clearly and if you have ever tried this then provide video or screenshot.

the command is working fine for me but as I have low rom (256mb) it cant save the image file to the internal memory. so is there any option to save this image file to external sd card?

hello,

I checked the script, it is using /proc/mtd/ location which is not there in my phone (using ES explorer)
Please provide the edit we can do in .sh file using notepad++

If I make backup using dd command in adb will it suffice or I need to modify ?

Thanks
