DBoot

DBoot is a small patch that enables starting the Media Nav unit directly into Windows CE 6.0, without starting the Media Nav firmware’s interface. This is useful when using the MICOM Config application, for activating the rear camera or activating the rear speaker. Also, having DBoot installed makes it easier to recover a unit stuck at booting, showing only the logo.

Notes:
1. This patch does not alter the official firmware and only enables a listener for touch gestures at boot, before the main interface opens.
2. This patch applies only to first and second generation Media Nav units (MN1 & MN2), firmware versions 4.0.6, 6.0.X, 7.0.5, 8.0.5 and 9.1.X.

Prerequisites:
– a tablet, laptop or desktop equipped with an USB port
– USB flash drive, FAT32 formatted, max. 32 GB capacity

DBoot 1.4 & DBoot 1.5

Step 1. Download DBoot 1.4 or DBoot 1.5 from the links in the table above, according to the Media Nav version.

Step 2. Extract the ZIP archive and put the file upgrade.lgu in the root of the flash drive – the file should be the first to be seen upon accessing the flash drive.

Step 3. Turn on the Media Nav and insert the flash drive in the USB port.

Step 4. Press Upgrade on the update notice. If no notice appears, go to Settings > System > System version and press Upgrade once the notice is shown.

Step 5. The Media Nav will reboot and DBoot will be installed. After the installation is complete, the unit will reboot once again and go to the main interface.

Step 6. Turn off the Media Nav, wait for ~30 seconds and turn it on again. It is recommended to unplug the flash drive from the USB port before turning it on.

Step 7. Once the logo is shown, touch the screen and swipe from left to right, repeating the gesture (at about 1 swipe/second) until the screen becomes black, meaning the Media Nav is rebooting. If it doesn’t turn back on, turn it on from the button.

Step 8. After rebooting, the Media Nav will boot directly in Windows CE 6.0. If a notice is shown, press “OK”.

Step 9. If, after Windows booted, access to the flash drive is needed (to run other programs, to copy files etc.), but it doesn’t show up in My Device, go to Start > Programs and select USB PHY On. At this point, the flash drive should show up.

Step 14. In order to go back to the navigation interface, open cereboot.exe. This will reboot the unit and it will turn on normally.

DBoot 2.0

Step 1. Download DBoot 2.0 from the link in the table above.

Step 2. Extract the ZIP archive and put the file FIRST_upgrade.lgu in the root of the flash drive – the file should be the first to be seen upon accessing the flash drive. Rename this file to upgrade.lgu.

Step 3. Turn on the Media Nav and insert the flash drive in the USB port.

Step 4. Press Upgrade on the update notice. If no notice appears, go to Settings > System > System version and press Upgrade once the notice is shown.

Step 5. The Media Nav will reboot and the first part of DBoot will be installed. After the installation is complete, the unit will reboot once again and go to the main interface.

Step 6. Delete upgrade.lgu from the flash drive and copy the file SECOND_X.Y.Z_upgrade.lgu extracted from the archive to the root of the USB flash drive, where X.Y.Z is the version of the current firmware. Rename this file to upgrade.lgu.

Step 7. Insert the flash drive in the USB port and press Upgrade on the update notice. If no notice appears, go to Settings > System > System version and press “Upgrade” once the notice is shown.

Step 8. The Media Nav will reboot and the second part of DBoot will be installed. After the installation is complete, the unit will reboot once again and go to the main interface.
