Thanks buddy,
The final solution was a life saver. I extracted all the customization files and here I am using the phone. It's cool & as we call it zhakaas. I think after using all this so many times, even I'll be able to help others with XS++ and Setool2lite.
My observations if helpful to other are:
1. Remove memory card also.
2. If you wanna debrand as well as unlock, you debrand first, then unlock and then use XS++ to flash FS only and customize with extracted files.
3. Chao you're done.
ENJOY!!!!;)
