Default (android 4.0) wintouch q74 tablet bricked

i update my tablet with a liquid rom using default android recoverymode. the installation was succesful but when i reboot my tablet, logo appears as usual and get stack in blackscreen. i could still enter android recovery mode but it only reads internal storage so i cant update anymore, usb debugging was not turned on. how could i get it back to life/unbrick my tablet. (it is not rooted anyway.)

so i tried livesuit v1.09 and connect my tablet while in recovery mode, (the computer detects it as softwiner761) still livesuit doesnt start even if i already selected an img file. system upgrade says "no available device". then i just nomally boot my tab and the computer detects it as an unspecified android, still livesuit doesnt start any progress. turned off tablet doesnt do anything so what should i do?

from wintouch site ive downloaded the the img and downloaded the latest livesuit.

fastboot devices doesnt work too. i have no more idea how could i unbrick this tablet. please help me how could i repair this.

please help me
