Hi Adrian,
In the root I mean that the firmware file is not placed in a folder on the SD card. In a FAT32 formatted SD card, the firmware file is the only file on the SD card. So no other files or folders are present.
If the blue LED does not light up, there is a problem with the power supply. Check whether the fuse is still intact.
You can also disconnect the power converter from the K3 and power the K3 with a power bank using the USB connection. The power bank must be able to supply enough power. If the K3 then works, you know that the problem is with the power supply.
