Custom ROM problems

[jrdatrackstar]

I have been trying all the custom roms, and even cooked my own. I always seem to have lock up problems, no matter how many times I hard reset or no matter how many different roms I try. Also, any custom rom I try that is based on the leaked sprint rom gives me battery problems. I will turn the phone off, and when I turn it back on a few seconds later, the battery will drop from like 80% to 60%, with no usage in between. The only rom that doesn't give me problems is the leaked sprint rom. However, I really want the rapidcharge.dll so that I can tether as long as I want to. Is there a way I can have the rapidcharge.dll in the leaked sprint rom?
