Unhappy [Q] INFOTMIC Y88 without recovery in boot loop

First rule, never purchase device without hard access to recovery (if you are in position to check it).

So, my tablet don't have hard (buttons) access to recovery, just trough the ADB (also in recovery, but I cant enter in recovery or in screen).

Tablet simply stuck on ANDROID until battery let it to loop. ZERO access.

ANY IDEA, please?!?!?

More device info on image.

If I note it well, it is just slightly modified generic and (very) basic AOSP.
