Best way to flash

[Oreo99776]

I have a flashed Sprint S2G2 from Sprint to Boost Mobile because it was cheaper, but oh goodness, I can't do this anymore! My internet is soooooooo slow, the reception is blotchy and sucky and I just hate it.
I want to know if its possible for me to flash over my phone to like t-mobile,cricket, simple mobile, etc. something with 4g possibly
well i just need something else.
I want to do this myself and not pay some one else like 200$ to do when i can do it myself. So i hope there are cracked versions of programs, hopefully.

I need things like tutorials,websites, etc. THAT WILL NOT WIPE MY PHONE, if it will PLEASE let me know ahead.Also please note that I am a N00B at this, but I have successfully rooted my phone myself.

-P.S. My phone does not have a SIM card if you were wondering

I may be wrong here, but I believe that if it's sprint branded; it's going to stay sprint services. I know Boost is operated by sprint, so I could see that. But I don't know if you could switch to another carrier unless it's unlocked/gsm model. :\ I could be wrong though.

The epic 4g touch can run on almost any CDMA network. It can be flashed to boost mobile, cricket, metro pcs, verizon, virgin mobile, etc.

They key to getting it working on those networks is to have a donor phone where you can extract all the NAM keys, esn/meid, and data keys and flash them to the epic 4g touch. Really isnt too hard once you have all the keys to write them.

That's what I've read so far on XDA about flashing to other carriers.
