How can I crack the sprint krzr k1m software and install it's original firmware

I have the Krzr K1m from Sprint. The way the Sprint programmers programed the phone is terrible. It is VERY slow and often freezes. It takes about 11 seconds to bring up the contacts page, which is very bad for a moto phone. So what I want to do is erase the sprint made firmware and install the original Motorola firmware. If this is not possible, I need some ways that I could fix the phone's speed. I took it to a sprint service center, they did nothing to it and they didn't help at all.

Error32,

Anything that you do to the firmware will void any service agreement or warranty with Sprint, so you risk turning  your phone into a pretty brick with no recourse. Also, flashing non-Sprint firmware to your phone may disable your ability to use it on the Sprint network ~ I mostly work with Verizon, so I don't know how closely Sprint checks this in real-time operation.

To do anything with the phone, your first step is to get Motorola Phone Tools (MPT). I've found the best way to get this is via Amazon.com, which frequently has it available. You'll also need a cable to connect your phone to your computer.

Do you have both of these already?

Cheers,

I can get the cable, but am looking to do it myself for free. Does anybody know how I can make a backup of the Sprint version just incase something goes wrong so that I can reverse it and restore my Sprint firmware back?

Well, here's the issue, you need the MPT to get the proper drivers to access the phone. Sometimes you can find them on the net (search google for "drivers krzr k1m"), but sometimes they are not valid versions of the drivers or even contain nasties.

I have found MPT at Amazon for something like $3.

Just out of curiosity, do you have a memory card in it?

I've heard that some memory card issues can make the K1m run slow. I'm not positive, but what I see online is that if you flash in non-Sprint firmware, it may not work on the Sprint network. However, here's how: http://www.howardforums.com/archive/topic/1259257-1.html
