Unhappy [Q] Polaroid MIDC1018 (A10 Tablet) Soft-Bricked

Hi XDA-Forums

I recently bought an Polaroid MIDC1018 , which isn't known at all..

I discovered that the device were pre-rooted and it is an Allwinner A10 Device, installed root apps and chainfire3d , but after installing chainfire3d's drivers the tab rebooted and i was stuck at boot screen (ANDROID..) I decided to install CWM for A10 Devices but i couldn't know how many partitions i had , because i wasn't able to use adb shell..

I installed the 10 partition version , i'm stuck with
E:Can't mount /cache/recovery/command
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't mount /cache/recovery/last_log
E:Can't open /cache/recovery/last_log

Also for some reasons the pc won't detect the tab when plugged to it..
No adb tool ,
Can't mount /system/ and others..
The only thing that work is "install zip from sdcard" (I don't have backup)

My Stock SDK : MID-A13-Android4.2-V1.0-20130121
As i said , my tab isn't known at all , not even in Polaroid.com 's list so i can't find stock rom..

Anyone to help me?
