Auto update worked on my Minix U9-H today and it didn't effect the device tree as I can still boot directly from the SD card.
installed latest version - USB install on a Minix 9-H running with AVR and 1080 Bravia panel - and must say I'm impressed. All of a sudden refresh rate switching works as advertised and audio passthrough has no problems whatsoever. Kudo's - this might be the best PQ from all my boxes (2017 Bravia with 17.6, Minix "androidTV" with Leia, Mibox nougat beta with 17.6, x86 windows with 17.6)
One thing however - the box does pick up time somewhere - I did put a couple of NTP servers in the settings - but it does not want to accept that I'm NOT in the UK and therefore do not want GMT. Not seen any timezone settings. Yes, localisation allows to select Australia but that in itself cannot accurately identify the correct timezone...
I'm sure it's a setting somewhere - in Libreelec - but where???
I just set the #1 timeserver to pool.ntp.org in the LE config and then set the correct timezone in the regional settings. Always has the right time. I use the transparency skin and to get to the regional settings in there, its settings-interface-regional
Thanks guys. I too could not get LE to boot directly from the SD card but it would work fine if I put the card in a usb reader. Running the upgrade with the device tree posted here solved the problem. I no longer have to rely on the usb reader. Thanks again.
