[Motorola Photon Q 4G LTE] ACiD GRiM:
I mean doesn't a factory wipe of /system clear off the proprietary files that CM needs? I just did it and installed and things are working as expected (except for HDMI), so maybe not. I was just under that impression from the red text advisory on OP and have always been sure to install a backup of stock system, then upgrade to CM when ever I feed a clean reinstall is needed, but not just for nightly updates.

This is the section that I'm concerned about, I'm looking onto what video format 131071 is, but it's appearing to me that the screen isn't liking the resolution 720x480, but maybe something will come up in my searching.

Interesting, reading more

I'll put $20 bounty on this if anyone can come up with a fix
