Default [Q] ZTE V9A System Formatted!

Please help!
I don't know if anyone will get my point but let me cite my problems as well.
I recently root my device (Reliance 3g TAB V9A/ZTE V9A) and installed CWM
Recovery. After creating a backup of my device, I reboot into CWM Recovery mode.
While trying to install custom ROM, I happened to format my system partition. My
custom ROM won't install/work and for the worst, my device wont start normally. Now, I want to restore from the backup I've created with CWM-Recovery, using my stock recovery mode (Android system recovery <3e>) since I don't replace my device stock recovery with CWM-Recovery but there is no Restore option. I only have-

-reboot system now
-apply update from sdcard
-wipe data/factory reset
-wipe cache partition


What do I do now? Is there any way to get my device working back? Can anyone help me with this?

Device specs-

OS - Android 2.3 (Gingerbread)
Screen - 7.8cms (7") TFT-LCD WSVGA screen, 5 Point Touch
Display - 1024 X 600 pixels
Internal Memory - 4GB Internal Memory + 512 MB RAM
CPU 1.4 GHz


Thanks in advance.
