Now it's working 1,h hours. It seems that adb is backing up, but there are also some entries which say "write error: File too large"
To large for what? I have a SD-card with 256 GB

it means that mmcblk0 is your SD card partition and it must be skipped

Hi! I changed the lines:

adb root
adb shell

this is (example) kernel output of OS Porteus at my PC :D

Ok, remove previous backup on your SD card and try these commands:

Код: Выделить всё

cd c:\adb\
adb root
adb shell
mount -o remount,rw /mnt/sdcard /mnt/extsd
cd /dev/block/;for i in `ls mmc* | busybox egrep -v 'mmcblk[0-1]$|mmcblk[0-1]p1$'`; do echo Backup of $i ...; dd if=/dev/block/$i of=/mnt/extsd/$i; done
P.S. not sure about busybox - whether he has egrep or not.

I don't see any error. So I think that the backup is done. Is it a complete backup of the system and how can I restore it?

Now I'm searching for a ROM with a higher Androidversion. The tablet has 4.4. Any idea?

Добрый вечер,попал в руки китаец samsung n8000,при загрузке allwiner,стоит пин который я не знаю,рекавери для хардрезета нет,точнее все комбинации кнопок перепробовал,ноль реакции,на матери надпись А23,пытался прошить через sd как в шапке,включается и дальше только черный экран,может не ту прошивку записал,точнее пробовал несколько разных,одна реакция,может кто подскажет как быть?
