Right. That was the same problem I had initially. A hard reset to turn the phone off then back on and then holding down the volume up button when rebooting got me into Safe Mode allowing me to uninstall the tweak.
That issue has since been resolved. However, I am noticing little glitches.
Quick Reply, when you set it to Windowed calls up the default system reply box behind the window when you are on the lockscreen. Also, today I was browsing and got a text. I dismissed the text and got dropped right back onto Springboard instead of the QR box just going away.
It works, but just not well enough yet. Hopefully, if this is the only alternative to Bite they improve it soon.
