Default Galaxy Grand i9082 keeps rebooting while formatting or restoring the /data partition

Greetings Folks!!!

Yesterday, I tried to install Xenon HD ROM on my GT - i9082, and it got into a boot loop. So then I tried to restore my CWM backup, but even that keeps failing because the phone reboots when the restore process comes to restoring the /data partition. I tried doing the "Wipe Data" option from CWM, but then at "Formatting /data", the phone reboots. Basically, if you do any formatting or restoring on /data, the phone reboots.
I am currently at 4.2.2 (XUBMJ4 Build). Some advice to get me out of this mess would be appreciated.
If I helped you, please feel free to hit the "Thanks" button
