I have tried to upgrade mAP, got one from the factory with 6.11.
Installed 6.24 and then upgraded to 6.25.
All LEDs are working and board booted just fine.
For your current device try to use reset button.
- firstly try to load backup BIOS by pressing reset button for 2-3 seconds during boot;
- if it does not help, try to reinstall device by Netinstall. Hold reset button for 15 seconds to launch Netinstall,
Let us know about the results.
