You cannot 'upgrade' your Rock64's android system. This will purge your installation and install the new A 8.1.
You need to unarchive the xz file so you get a .img file. All other information concerning flashing OS images can be found here: http://wiki.pine64.org/index.php/NOOB

Luke, I have unrar the XZ file and got img file, then upgrade by Android Tool V2.38. It showed "Loading firmware failed".
How can I do now?
Thanks
Its not a file you can use with RK tools. You need Etcher similar dd utility. Read the link I posted for you.

Yeah I have to use Etcher 1.44
1. select Image: I choose stock rom 8.1.img
2. Select Drive: It said "connect a drive" but I cannot click on it, It doesn't happen.

Please tell me how to use Etcher 1.44.
