Getting a replacement, should I flash back to stock

[kilen]

Hey Everyone!

I'm running EnergyRom and had my Touch Pro up to the service center this evening because my vibrate motor was sounding like a duck. The Tech took it apart, fixed the motor, but then the screen wouldn't turn on. He took it apart again and got the screen working, but the vibrate wouldn't work at all, so he decided to order me a replacement.

Here's my question. When I go back to get the replacement, do I need to be back to the stock ROM? Will they actually do anything with my phone, or will they just activate the new phone? If they're just going to activate the new phone then I might just leave it as is.

Any thoughts would be greatly appreciated!
