seguro es un problema del kernel, yo no se mucho de esto pero me parece q debes de cambiar la carpeta de kernel de la rom por la carpeta de tu kernel

Why do you think the cube firmware can work on this pad? Every tab has it's own kernel (hardware abstraction layer).

Fail in mask-rom mode indicates that the NAND is corrupted. Nothing you can do. Sorry.

I guess it is easier to spend the money for a new tab. RK3026 production runs out, the successor chip RK3126. Tabs are around 50 USD.

ese problema que mencionas parece que es debido a que no has cambiado el kernel, te digo porque a mi me paso lo mismo al cambiar el TWRP y era tema de kernel
