I flashed the wrong bootloader and bricked my Kindle Fire HD. Replacement main board had it back up and working in 20 minutes.
Easy, just be careful with the ribbon connectors.
You can do it
Replace a damaged or malfunctioning motherboard for a Wi-Fi model Kindle Fire HD 8.9" and fix a bricked tablet. This is a used OEM part.
