3. Go to the file browser, and enter the .rockbox directory (you might need to set
the File View option to All.)
4. Play the file rockbox.ucl, and follow the instructions. The plugin handling this
is rockbox_flash, a viewer plugin.
13.5.5. Restoring the Original Flash ROM Contents
In case you ever want to restore the original flash contents, you will need the backup
file. The procedure is very similar to initial flashing, with the following differences:
1. Check that you do not have any firmware_*.bin files in your player’s root.
2. Select Plugins → Applications, and run the firmware_flash plugin. Write
down the filename it displays in the first screen, then exit the plugin.
3. Connect USB, and copy the flash ROM backup file to the root of your player.
Only use the backup file from that very box, otherwise you’re asking for trouble!
Rename the file so that it matches the name requested by the firmware_flash
plugin. Safely disconnect USB.
Now follow the instructions given for initial flashing, starting with step 3.
13.6. Optimising battery runtime
Rockbox offers a lot of settings that have high impact on the battery runtime of your
player. The largest power savings can be achieved through disabling unneeded hardware
components – for some of those there are settings available. The following provides a
short overview of the most relevant settings and rules of thumb.
13.6.1. Display backlight
The active backlight consumes a lot of power. Therefore choose a setting that disables
the backlight after timeout (for setting Backlight see section 8.4 (page 56)). Avoid to
have the backlight enabled all the time.
13.6.2. Anti-Skip Buffer
Having a large anti-skip buffer tends to use more power, and may reduce your battery
life. It is recommended to always use the lowest possible setting that allows correct and
continuous playback (see section 7.5 (page 51)).
13.6.3. Peak Meter
The peak meter is a feature of the While Playing Screen and will be updated with a
high framerate. Depending on your player this might result in a high CPU load. To
save battery runtime you should switch this feature off (see section 4.3.2 (page 29)).
