[Tutorial] How to backup a Spreadtrum Android phone using ADB
#1
(This post was last modified:02-22-2017, 09:07 AM by hovatek. )

This guide is for Spreadtrum (e.g Itel, Old Tecno etc) Android phones. You may also use the Miracle Box method @ https://forum.hovatek.com/thread-17226.html

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)

Hi,
I tried to backup an Itel It1403, I got everything right up to the point where I have to type the command code
su -c mount -o rw,remount rootfs /
su -c "tar -xvpf /data/local/tmp/backuptools.tar"
su -c "./mkbackup.sh"

The screen shot of the response is attached with this reply.
Please I would like to know where I get it wrong.

Hi Hovatek,
I tried doing a backup for an itel it1452 but after the last command it gave me an error which says "sh: applet not found". So I followed your instruction to install Busybox Installer (Jrummy) and started the process all over. All the commands ended up fine except the last one which gave the following output: [email protected]_sp7715ea:/ $ su -c "./mkbackup.sh"
su -c "./mkbackup.sh"
dd: can't open '/proc/mtd': No such file or directory
grep: firmware.info: No such file or directory
[email protected]_sp7715ea:/ $

Please help me solve this. I am attaching the full screenshot.
Thanks.
