Apps Sprint Hero not booting into recovery

So I rooted my Sprint Hero and everything went fine, but when I try to flash a recovery image it says the file isn't found even though I checked the spelling and if I ls my sdcard it shows up.

More importantly though my phone won't boot into recovery mode via the command prompt or the Hboot screen. It just shows me a picture of an exclamation point and a phone laying down, one time it game me some error

E: can't open/cache/command or something like that.

Please help and let me know of any other info I need to give
