How to make full dump recovery.img in Mediatek device

Again I'm going to teach you on how to make backup and fulldump your stock Recovery.img in Mediatek Device manually via Terminal Emulator or ADB Command in Mtkdroidtools.
First you need to root your device.

Requirements:
Rooted
Terminal Emulator(download in Playstore)
 MTK droid tools







Procedure:
1) Make sure phone has root shell access (rooted) , if you dont have root then please root with IROOT and install superSU+ binaries.

2) Make sure USB debugging is enabled on the smartphone

3) Download MTK droid tools 2.5.3


4) install PDAnet abd driver package

5) run MTK droid tools and open a new ADB SHELL.

1. First check your mountpoints and partitions via this command:
type this command:
adb shell cat /proc/dumchar_info
via ADB COMMAND in Mtkdroidtools

via Terminal Emulator
type this command:
adb shell cat
cat /proc/dumchar_info

2. Then Check for the mountpoints of Recovery.img

3. Type this command:
adb shell mkdir -p /storage/sdcard0/BACKUP

BACKUP folder must created in your SDCARD.

4. Type this command:
adb shell su -c "dd if=/dev/block/recovery of=/storage/sdcard0/BACKUP/recovery.img"
 or
adb shell su -c "dd if=/dev/recovery of=/storage/sdcard0/BACKUP/recovery.img"

You must check your mountpoints usually for new 64  BIT Mediatek device like MT6795 , MT6752 , MT6595 , MT6753 and MT6735

Use this command:
adb shell su -c "dd if=/dev/block/platform/mtk-msdc.0/by-name/recovery of=/storage/sdcard0/BACKUP/recovery.img"

5. Wait to finish! You can now have backup stock recovery.img
Note: This take only few minutes. check the file size usually not more than 15MB.
