Default [Q] A510-cannot get into recovery mode/boot

[A510] I upgraded my rom and then tried to reboot. I get the boot animation where it gets stuck there. I shut off and try to get into recovery mode and get this message: "Bootloader Version jb-d0ca683 (unlock Mode). When I let it go it goes back to boot animation and won't fully boot.

When I hold down the .. volume key I get "Bootloader vJB-d0ca683 (unlock Mode): starting Fastboot USB download protocol

it stops there.

HELP!!!!!
