Stuck in fastboot, no udc_start() topic

I have flashed the latest version of CloudyG2 over my D802 CM 12 but just after I have done this I have realized that the ROM was for the Korean version of the device! My Phone is now stuck with a blackscreen with "fastboot started" written on. I seen a lot of threads of issues like this, but most of them have also "udc_start()" and mine doesn't. I can't access recovery or download mode, but I can access hardware buttons mode, I have done the procedure to get to the recovery at least a thousand times with no result. Any suggestion or procedure I can follow?
