Ok, you can use Google to find out where the ISO is.Usually a search on a search engine gives you a lot of answers.
However, it's available directly from Microsoft here.
You have to download the 64bit version of Microsoft.
The OS will be activated automatically the first time you'll connect it.
Be careful: if you don't know how to install it, don't install it.
You can loose all your data.
Does the website have the OS specifically made for Hi10 plus? Because i heard that Chuwi tablets come with customized OS. I just wish someone had downloaded and saved these files somewhere on their computer. The links here keep giving the 429 error thanks to stupid DropBox and i don't know when Emily is going to show up again.
I have tried 4 different cards i have, 32 GB Transcend/Kingston/Sandisk and a 64GB lexxar. Some Class 10, some UHS-1. Yeah i've read somewhere else there was a BIOS update that fixed SDcard issues, but i can't seem to find any info about it.
