Rockbox port to YP-S3
Hi, I'm a developer for Rockbox, an open-source firmware for mp3 players, and I ordered an YP-S3. I'm looking into porting Rockbox to this player, it has the same kind of system-on-chip (S5L8700) that is in a couple of other players that are currently also under investigation for a Rockbox port (e.g. Meizu M3/M6, possibly Ipod Nano 2G).
Doing a Rockbox port requires me to put my own compiled firmware on it which comes with the risk of accidentally making it inoperable (sometimes called "bricked"). Does anyone know if this player has some kind of recovery mode? For example some kind of key combo that can be held during boot that allows it to reset the firmware, or that allows to send a recovery firmware via USB (e.g. DFU - device firmware update mode)?
