[Tutorial] How to backup a Spreadtrum Android phone using ADB

#1
(This post was last modified: 07-07-2017, 01:06 PM 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

Requirements


Steps to backup a Spreadtrum Android phone using ADB


  1. Download BackupTools.tar and copy it to the same directory as adb.exe
  2. 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"

  3. 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 
  4. 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.
