fastboot reboot

This is ONLY for the RUU ZIP file and not a normal TWRP-flashable ZIP
I put a ROM in my sd card and managed to flash it even thought it failed, but now i got a system going on. Now i can access fastboot!!! I used your method and the RUU u gave is actually what i used!!! And it worked!!!!!!!!!! Thank you so much man!!!! I dont even know what to say!!!!!
