1. In current versions of LE (at startup LE from the media) in the shutdown menu, it is possible to choose to reload the system, which is located in the internal memory ("Rebot from NAND flash\Android"). Ie if you set Armbian in eMMC and when you run the LE from external media, you can choose a LE to restart the system , which is in the eMMC.
2. What version of LE are you using ?
 
In image Stretch not use a test repository.

I apologize for the delay in response. Before upgrading, I recommend doing a full backup (utility ddbr).
1. Then you can try updating via apt. If the system fails to start, you will have to perform a clean installation.
2. I haven't tested the packs mount in x86.
 
 
The start order of systems in the presence of external media. If you have a bootable system on a USB , it runs first USB -> if USB is no system (or no USB), checks the system on the SD and if there is, it runs SD -> if there is no system on the SD card , run system from eMMC.

You can use unlimited number of systems on external media. When you connect together several media, always run the same system in order of priority - USB -> SD. To run from SD card, you need to be sure to turn the system off USB.

I already replied earlier to this question. At the time of assembling the images in the standard repositories Jessi didn't have the right versions of packages. Now there have been many changes in the repositories (test disabled) and now I am collecting images of Debian using the official branches Stretch. By the way, to all , I will repeat for the, at the moment (when I checked last time) in the thread Jessi broken packages, which are responsible for mounting a label, so when you try to upgrade from Jessi you risk to not run from external media system.
 
Video hardware acceleration is only in KODI. Therefore, any other program (including browsers) use softbuy processing, which need all the resources of the processor (the more powerful the processor, the better the video quality).
If you want to get a full-screen video in the browser - it can be assembled using the library libMali.
