I don't have any of your issues.
The only problem you can have is that your box has received its multiboot partition from an old OpenATV image, which is different from the system the manufacturer (and OpenPLi) is using.
But if you have OpenPLi 8.0 installed, and that boots, then you don't have that problem. And no, images are installed in separate partions, and don't see each other. Like installing Linux and Windows on the same PC.
For the SF8008, two types of images are available:
- the USB image, which contains the bootloader / bootmenu and the OpenPLi image
- the Multiboot image, which only contains the OpenPLi image.
If you flash the USB image, the entire flash will be erased, the bootloader/bootmenu is reinstalled, and the OpenPLi image will be installed in the first slot. All other multiboot images will be lost.
You can only flash the multiboot image using Online flash, or via the flash option in the boot menu.
As to plugins: we can help or comment when it comes to third party plugins. We don't know the code, we haven't written it, we can't update or fix it. So you need to find the author.
For plugins from the feed, they shouild all work. If they don't, we need more info than "it doesn't work". Provide descriptions of what you do, what you expect, what happens, ideally with logs.
Most people use EPGImport on a daily basis, including myself. And I've never seen a single issue with it in the last few years.
So, if you have an issue, provide a proper bug report, which allows us to reproduce the error. If not, and it works for us, there's nothing more we can do.
The same is true if an online flash doesn't work.
