Eros Q Native: Add Original Firmware Boot option
Hold "Play" to boot the OF, or boot it from the recovery menu by holding "Vol. Up". If you had the hosted port installed on your player before installing the native port, you'll still have to go through the hosted bootloader. A couple notes: - When booting from the menu, the recovery menu disappears, then reappears before going into the OF. - You need to hold the play button for like a half second after the blue light comes on in order to get into the OF. The recovery appears to be there, but it doesn't seem to be intended for end users - it just says "Updater V1.1 - Insert TF Pls". I haven't tested it beyond seeing that it boots, so I'm going to comment it out for now. Change-Id: Ie271ee479bb628cc74141b7fe07273b3f193f358
