Welcome to Gurus! The EVO can be fully flashed to Cricket service, that is the good news. Here is the thread that will get you to the promised land: [Only registered and activated users can see links. ]

Now, if you are not interested in buying the solution, there are other options available. Look around xda-developers.com, ppcgeeks.com, and other Android forums. They give a lot of insight as well on the process.

Right here on Gurus, we also have a whole section on all things Android.

I will say if this is your first phone you have ever flashed, then you are starting out on a whopper. lol I would recommend either paying someone to do it, or do a lot of reading and perhaps start with a more simple phone and build your confidence.

It would be a bad deal if you bricked that phone because of a mistake.

On a side note, if you wanted to give up on flashing it, I would buy it from you for $50. Just let me know what your paypal address is. I will even pay for the shipping.
