so what happens if you boot into fastboot? Phone just restarts or does it stay black? :)

And why do you need to boot into fastboot to flash stock rom? (see thread name you are posting in)

Hi, I just flash the 2.5 rom stock with QFIl.
After the flash, first time I fail then second time works, my phone reboot and stay on black screen with blue zuk logo.
I don't know what can I do.

If I stay on power button, the phone reboot and black screen with blue zuk again.

Please help me.

Just read the OP and you'll find out how to translate to English.
