First, thank you so much for giving us AEX for the X4. Aex is my favorite room and just got this phone and pleased to see it was available. However no matter what I use for security, pin, password, pattern, Twrp doesn't recognize it. In order to make backups or other functions in TWRP, I need to remove the pin before I boot into recovery. Has anyone else experienced this or know what the problem is?
