unknown clone RK3188 firmware selection

Please help me decide which firmware should I flash to clone that matches V88HD i guess.

The tablet has only two buttons, BACK and POWER. I already rooted and install CWM recovery following instruction in the head post.

CWM recovery is working great with gestures. I haven't seen that before.

Now I'm selecting ROM to FLASH for the first time on this device and a little nervous about it.

I need to change ROM, because of huge instability of WLAN. I hope it is ROM issue.

Tablet is sold in Bulgaria under with manufacturer AKKRON. Model is called qr10a16bt
