Rescue mode¶
What is a rescue software update¶
The rescue software update:
Upgrades the NAO’s software with the given OpenNAO software release and
Resets the whole system in a similar state as if the robot was just out of the factory.
Therefore, any data put on the robot will be erased during the rescue software update process,and any settings will be reset to their default values too.
Warning
After a rescue software update:
- all user’s data put on the robot will be irreparably lost;
- all settings will be reset to their default values
When should I do a rescue software update¶
Rescue software update should be used:
- when something goes wrong and NAO does not boot normally anymore;
- when you want to completely reset NAO to a known state;
- (rare) if you want to downgrade to a former OpenNAO software release.
Alternative method¶
- NAO boots normally,
- you do not want to use a release older than the current one, and
- you want to keep all user’s data and settings,
