I have been booting from LibreELEC-S805.m201d.arm-7.0.3.3-update.zip and factory_update_param.aml on a usb stick using the toothpick method. Am I using the wrong file for this?
Just
1) download the *.gz file from the Update folder
2) remote connect to your kodi (use Windows explorer \\192.168.1.xx or whatever your Kodi-IP is)
3) copy the file into the UPDATE folder of your Kodi
4) reboot
5) The update will unzip and install automatically
