If your bootloader is locked again, you’ll want to unlock it first despite the orange state. But as long as it’s actually unlocked, you’re probably at the stage where you’re ready to load TWRP into the system and then you can adb reboot recovery to get in. If you aren’t planning on wiping everything, be sure to disable ANY AND ALL screen locking security. If you have anything beyond swipe (even just a basic pattern) enabled, TWRP will not be able to access the data and you may or may not be able to reboot back to system without wiping data again. As people will repeatedly note in just about every release, the Teracube TWRP can’t decrypt yet, so it gets angry when you make it try.
