correct password not accepted!

[saucysassy27]

I have flashed my sprint htc touch pro 2 to work with boost mobile!
my phone started to slow down and then i pulled the battery out and its prompting me to enter my password! I am entering my correct password and it keeps saying incorrect password! ughh!! (my heart hurts!) So it seems i will have to do a hard reset! will this mess up the flashed program? will i still be able to use my phone with boost and all features?
