Thanks for the wonderful walk through on flashing your ROM. I performed the steps exactly as you said, and the phone is working fine however am unable to restore my contacts backup.
I have a GT-S6102 (Galaxy Y duos) purchased in UAE.
I followed the steps on using the CWM, and i used the CWM-try1 zip file posted by you.
After installing TECHNODuos, I found my contacts database was not restored, therefore I was trying to locate the data.img file to restore from infact the backup folder contains no .img file at all.
Please help. does this mean if i needed to restore back to the stock ROM I will not be able to do so?
Is there any way to re-gain my contacts from the backup that was taken.
