[Q] Need Urgent Help !! topic

Hi please help me with the following:

I was running Cyanogen Mod 10.2, decided to update my phone with stock ROM.
Using ADB I re-locked my bootloader. The RUU which I downloaded does not complete the installation and says find a correct RUU.
Which I am not able to find. Now thinking back to roll-back to Cyanogen and unable to unclock the bootloader via ADB.
Please help with how to unlock the bootloader or with a right RUU:
