I have hard bricked my tab 2. It is a tab 2 wifi lte (verizon) 8gb 10.1 and need the stock bootloader and etc. I have it being fixed but the person is asking for a dump.
We can backup unbrick img file via Terminal Emulator app or via adb command with the rooted tablet.
Here the command via adb command:
adb shell
su
dd if=/dev/block/mmcblk0 of=/sdcard/backup.bin bs=1048576 count=256
The command via Terminal Emulator app:
su -c 'dd if=/dev/block/mmcblk0 of=/sdcard/backup.bin bs=1048576 count=256'
