Root galaxy pocket blocks on samsung logo after wrong build.prop edit

[blacklava777]

Hi, by mistake I edited build.prop with wrong phone lines. I did a backup of the original build.prop, but now the phone freeze at the samsung startup logo, I can only access the recovery mode but cant do anything from there.
Tried to connect the phone via usb to windows and use qtADB, but it cannot recognize the connected phone. Any ideas? is it bricked?
thanks in advance.
