After rooting my KFHD, which was successful, I rebooted into TWRP. The screen went off after a while and did not respond to any buttons, so I hard reset it. Since then, KFHD has been stuck on boot screen (orange, not blue).
ADB is offline, fastboot won't find the KFHD, anyone knows what is going on?
EDIT: I have noticed that Lab126 (KFHD 8.9) device shows up soon after I push the power button, but only for about 3 seconds. ADB and Fastboot still don't work during that period.
