Ultra has 3 software levels:
- eBoot: Starting component which runs the operating system.
- Operating system: Executed under TwoNav and controling the more basic operations of the device.
- TwoNav: Executed over the operating system and interacting with user.
Normally, software updates are for TwoNav, but eBoot and operating system can also have updates.
- The user should know that this is a delicate process. It must be applied correctly, otherwise it could leave the unit unusable.
- In order to avoid losing data during the updating process, please copy all your personal files contained in 'TwoNavData/Data' to computer (security copy).
- Updates might take some minutes, you might need to wait so left the device working until further steps are being indicated.
- Enough battery is needed to update the operating system, at least 30 min.
