Tablet [Q] CHUWI V88 - what kernel?

Hi guys,
I have a problem with kernels. I have 2 chuwi v88, the first has got the ROM by OMA, 3.2 version, but the second has a strange kernel.
I explain better:

i can find my kernel (#419) but i see that i can't put that kernel in a "QUAD" model.

Firmware V88/V88S 20131223 - start S/N V88/V88S 16G1130800001 and V88 16G2130800001 (without QUAD in the S/N) - kernel bob #419 preempt 23.12.2013

So, here is the problem: i have a "QUAD" model and a #419 kernel installed by default. What is wrong? The device S/N, the kernel, or all is ok?
What kernel should i put if i want to install another ROM?

There is the new 3.3 OMA's ROM with the kernel #98, can i put that kernel?

If the kernel is wrong, what i have to flash?
The model is a V88 16G2140300190

thank you so much
