[Q] CM11 daily - suddenly locked out with encrypted /data
I have an HTC One M8, running the dailies of CM11. Yesterday sometime the phone locked itself, and now all I get is "Type a password to decrypt storage". I've done a factory reset with no luck, wiped and re-installed the ROM, etc, and I always just get this prompt when booting the phone.
I can get into recovery (PhilZ) but recovery is unable to mount or format /data, and I feel like I'm pretty boned here. Recovery takes a while to load, which is interesting. The phone is *NOT* stolen, this literally happened between when I got off a plane (phone was fine, I turned off airplane mode and put it back in my pocket) and when I got to my hotel. This was over the span of maybe 30 minutes... I have no clue how I could have done this, I certainly didn't explicitly decide to encrypt the phone.
Is there anything I can do? I am still able to connect adb, etc, when at the bootloader.
