Phone only boots to the Google logo screen, and then goes black with the backlight on

I flashed the latest Resurrection Remix ROM, through TWRP before and after a wipe. The ROM installed fine, and then I clicked on open gapps to install it. The gapps were a bit old and so the log said that it's quitting installation since that version of gapps is not compatible with the ROM.

Then I wiped, and tried to reboot. I can only get to the google logo (with the unlock sign underneath) and after that my screen goes black and just blinks with different backlight intensities. The same happens when I try to access the bootloader/recovery : Google logo followed by black blinking screen.

Any idea how to fix this? Thanks
