Sprint XPRT on Boost
 

I have recently purchased a used Sprint Motorola XPRT. And currently have a Sprint plan whose contract has ended.

I want to get Boost's Android Monthly Unlimited Plan and use it with my Sprint Moto XPRT.

I've seen things on the interwebs that say it is possible to use Sprint phones with Boost plans. Some say you must flash, others say you don't have to flash. Nothing is conclusive.

Is it actually possible? And if so, how do I do it?

Thanks!
