Welcome to the forums.

First go here : BlackBerry® Software Updates
Download the OS for the 7750 or the 7250 whichever you have, your thread title says one, your profile says the other. Download the correct one you need for your device.

Once you have it downloaded, install it to your PC by double clicking in the file.

Once you have it installed follow these steps. How do I wipe the BlackBerry using Jl Cmder? - BlackBerryFAQ

You will be left with a JVM 507 error, from there follow these steps.
