I have an Epic 4g that has already been flashed onto the cricket network and I have been looking everywhere on steps and answers on how to root and install/flash a cm mod on to my device.

My main concern is whether doing this will take my phone off of the cricket network (only because of the use of the word flash). Will doing this disrupt my use of the phone? Also I cannot find any definitive article on how to root my device, and an answer if this will also take my phone off the network. If anyone has steps of knows where I could find them on how to perform these actions I would love to see and use them.

Any help on this would be greatly appreciated, if anyone could shed some light on this for me at their earliest convenience I would be most thankful. Thank you all for your help.
