Some important notes before flashing for you guys and some others.
The kernel in this dev image has been changed from kszaq/8.2 to official LE/9.0 pre-alpha, this is a big change and something I have held off from changing to for a couple of reasons which are listed below.
If you have LE installed to internal this image will not boot as the partition layout in the DTB is different. You can still install to internal but you will have to boot from SD and then re-run the scripts and if you go back to another image then you will have to do the same again.
Devices with NAND will not be able to run LE from internal memory due to the LE kernel having no NAND driver.
There may be frame drops/skips with certain content however I can't say with 100% certainty that this will be the case because it has been some time since I last tested it.
DTB will require updating or your box will not boot however this should be done automatically as part of the upgrade process.
If flashing this image, I very HIGHLY recommend making a back up.
If your device boots following the upgrade then I expect this to run just as well as any other release, I make these notes just so you are forewarned. DO NOT complain, if your box goes bang!!
I wanted to report that this devel update works very good with my 905x box, no playback issues. I had hdmi-cec (LG TV remote) and screensaver problems with the previous builds which are gone now. (had to reset the cec driver)
