In short: it is necessary to execute the "toothpick method" again, because aml_autoscript is executed only in this case.
Thanks again but I seem to be confused about the terminology. It's been a while so I can't be sure but I don't remember having used the toothpick method for anything to make 9.2.8.8 - Kodi 18.9 run on my box, especially since I kept booting LibreELEC from the SD-card. Now, I would like to upgrade to the latest version that can run on my box. Can any of you point me to the correct img to download and what dtb to use and boot process to use? Thx!
