Hi Casey,
Hope you are staying healthy, safe and sane.
I recently purchased the Fenvi T919 that you recommended in this guide and followed your directions for the installation and applied proper patches on the EFI directory. The computer booted up fine and worked with out flaws for 3-4 days but recently started giving issues on boot. I am attaching a photo here
Luckily I have bootable clone that is up to date and able to boot into that, but wondering if you can provide some tips for troubleshooting. The clone drive sees the WiFi/BT card and works with out issues. I can even clone back to my original boot drive and can boot from that drive, but only once for some reason. If I try booting from the Original drive again, after cloning from the backup, I have issues.
Happy to send along my EFI folder if you think that will help.
Thanks,
andre
