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
, or preferably
rombox.ucl
, and follow the instructions.
The plugin handling this is
rockbox_flash
, a viewer plugin.
11.5.5. 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.
11.6. 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.
11.6.1. 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
(page
11.6.2. Audio format and bitrate
Your target uses flash that consumes a certain amount of power during access. The
less often the flash needs to be switched on for buffering and the shorter the buffering
duration is, the lower is the overall power consumption. Therefore the bitrate of the
audio files does have an impact on the battery runtime as well. Lower bitrate audio files
will result in longer battery runtime.
Please do not re-encode any existing audio files from one lossy format to another based
upon the above mentioned. This will reduce the audio quality. If you have the choice,
select the best suiting codec when encoding the original source material.
