Help Need Help! Partitioning went wrong

[krokoks]

Just got my new Tablet ME rainbow 7 quadcore. I rooted the device and it went fine. The tablet has 1gb phone/system storage and about 4gb of Internal storage. I partitioned the internal storage using mini tool partition wizard, followed the instructions carefully and its done.
But after I rebooted my device, somehow it got messed up. The Internal storage shows 0.00b and Misc of 20kb. I tried to access it again via my pc but when i turned on the usb storage on, I cannot access it. Need help to solve this issue

Is there a way to somehow recover my internal storage or repartition it again?

Thanks alot, hopefully anyone out there can help me.

Thanks.
I read some forums that need to install a custom recovery for my device. The problem is I'm having trouble installing on because my device is not supported on either CWM or TWRP. Any other way to install a custom recovery?
