Reflash Blue Pill devices

If your Blue Pill device has become totally unresponsive - you cannot contact it in any way - the solution may be to 'reflash' the entire system software. 

The reflash is not to be done as a factory reset and can only be done after other troubleshooting steps have failed. If you are unable to access the panel's web interface, try accessing it via <IP Address>/system/settings. This would open up additional troubleshooting steps. Additionally it may be possible to access the panel's web interface by enabling the panel's wifi access point   

NOTE: For this procedure you need the assistance from SKAARHOJ Customer Support !

Please contact: support@skaarhoj.com

ALERT: This procedure will ERASE ALL configurations on the device.

It is not possible to roll back SkaarOS versions, even by reflashing. 

REQUIREMENTS

You need the following software:
• BalenaEtcher version 1.18 or later   https://www.balena.io/etcher/  (free download)
• skaarOS image file   (this can only be obtained from SKAARHOJ Customer Support)
• The device needs internet access after the procedure to sync its settings with our server

1. disconnect power to turn the panel off
2. make sure you have the 'skaarOS' image file ready on your Desktop (you get this file from SKAARHOJ Customer Support)

The Blue Pill device should start up, and display the DHCP IP address it can be found at.
- For initial setup we recommend a network with DHCP server -

Important: After reflash the Blue Pill device must be restarted (done in step 10). At this time it MUST have internet access. This is needed to get basic settings from our server.
