Can't boot into system epic 4g t after twrp flash

[kgash]

I just attempted to flash TWRP recovery on my rooted epic 4g GB27. Everything went smoothly till the end when I got a message that TWRP could not be installed. It then tried to reboot. The Galaxy SII logo comes on and then the phone turns off.
Even though it said it was not installed, I can boot into TWRP recovery but rebooting system from there gives the same brief Galaxy SII logo and shuts off.
What can I do to get things working again?

Thanks,
Ken Gash

Welcome to the forums. I would say try loading a custom ROM onto the SD card and flash it in TWRP. See if that helps.
