FYI, FontHack's Auto Hint options makes my K3 go into boot loop. I had it first time, didn't know to fix it. Then factory resetted everything, setup again, and enabled Autohint again

Then I was able to catch usbms while in bootloop and remove the autohint file. Then it booted all right.
Should I share with my fonts I used? So you can debug it for future.
