Backup NAND Flash of your rk3188 device

[[email protected]]

Hi,
I have this rk3188 tv box:

The PCB board seem like the Doobol U2.
I want to change the OS from Android 4.2.2 to Ubuntu or other linux...
But, before, I want to backup the NAND flash so I can to resotre the Android OS via RockChip Batch Tool (if I will want...).

How can I backup the NAND flash before I install another linux OS?
Thanks!

Of course you can backup your current ROM using a tool like Online Nandroid Backup. But more importantly : will you be able to restore the backup, because for that you need a custom recovery. CWM for example seems to work on some devices, but most Rockchip devices are flashed using the RK batch tool. And I don't know if you can restore a nandroid backup using the batch tool. Maybe a more experienced user can shed some light on this.

No, the batch tool doesn't do backups. That's why I would love to have a custom recovery like CWM or TWRP.
