This way backup only the system folder... Then, every apps data are not saved.

yes this the way to generate the system firmware of the image not the data . for data backup you can you TB or any 3rd party app available in play store

Actually, I dont want to use a playstore (data couldn't be well backup if the phone is working...) I found a solution with ADB shell and in recovery mode. (dd command)
Thank you for your reply =)

I think I got it figured out, wont know for sure until I get my phones to test.

Anyway basically I just

cat /proc/dumchar_info

this gives me partition info, from there I dd partition contents to sdcard, example below is to pull your recovery.img from the info you posted.

to pull eg backup

dd if=/dev/block/mmcblk0 of=/sdcard/recovery.img bs=4096 count=2560 skip=10112

to restore

dd if=/sdcard/recovery.img of=/dev/block/mmcblk0 bs=4096 seek=10112

This post has made my day, and it seems to be only method for my tablet to get its rom dumped. I tried emmc and mtd but didnt work. Now as i made the recovery.img in my sd with the help of mentioned command, how do we supposed to know the bs count and skip stuff of a partition? so that i can make a complete dump. Any help will be highly appriciated and will complete my research on this topic. Thanks

Thanks, thats how i knew MTK droid tools work to make a rom backup using exect same method and make a scatter file with all blocks info to restore it later but it all happen in background. Btw i successfully made the rom dump of my tab with MTK droid tools and make it sp flash tool compatable. i was unable to get my tab detected by MDT because PDA net driver was not installed prevously.

i am also having this same issue. By using this command "dd if=/dev/block/mmcblk0 of=/sdcard/recovery.img bs=4096 count=2560 skip=10112" dumping of recovery.img was successful but i can't figure out the bs, count and skip for boot.img. can you please explain how to find those values to dump boot.img or any other partitions.

This is the output of my dumchar_info:
