Had that happen as well. I waited until after the third time the LG logo showed, and then released the power button, while keeping the vol+ depressed, and the fastboot screen showed up.
It seemed a little hit or miss though as a couple of attempts just went to normal boot.
And if there's any more problems still I might be able to help. This is most definetly the most tricky partMy sincere thanks to all developers.
Installed adb and fastboot, have a root, installed busybox, enabled developer mode, installed drivers.
Then ran script, it looks like it ran.
Now, I am at the beginning of part 2,
I cannot get into fastboot mode. Power off, connected to usb, power on and press vol. up, I see LG logo, then vibrate, then blank screen, and it repeats. After few times, sometime it shows boot animation, then goes back to LG logo and vibrate with computer ding-dong noise.
what would you suggest I should do? do I repeat Part 1?
thank you very much for your help.
