Can't boot after install (Stuck on gray screen)

[alonikomax]

After installing Yosemite with macpwn using clover (normal clover) I can't access the system.

Stuck on gray screen with mouse.

If I try to rebuild caches (using -f or safe mode) I get few errors:

 

Warning: couldn't block sleep during cache update

Warning: proceeding w/o DiskArb

 

Then it tries to rebuild kernel cache but after few seconds I get timeout.

Then it continue to work and get stuck on

 

kext com.apple.driver.AppleMobileDevice 30300900 is in exception list, allowing it to load.

 

If I use only -v I get to the gray screen.
