The 7.1-r3 is mainly a bugfixes release of 7.1-r2. It based on Android 7.1.2 Nougat MR2 security updates (android-7.1.2_r39). Some newer features are also back-ported from 8.1 release. We encourage users of 7.1-r2 or older release upgrade to this release.
This release contains four files. You can choose one of these files depends on your devices. Most modern devices should be able to run the 64-bit ISO. For older devices with legacy BIOS, you may try the 32-bit ISO.
To use an ISO file, Linux users could just dump it into a usb drive to create a bootable usb stick like :
dd if=android-x86-7.1-r3.iso of=/dev/sdX
where /dev/sdX is the device name of your usb drive.
Windows's users can use the tool Win32 Disk Imager to create a bootable usb stick.
In doubt, try the 32-bit files for legacy BIOS devices and 64-bit files for UEFI devices. Please read this page about how to install it to the device.
Except the traditional ISO files, we also package android-x86 files into a Linux package rpm. It allows Linux users to easily install the release into an existing Linux device with a standalone ext4 root partition. On an rpm based device (Fedora/Red Hat/CentOS/SUSE...), just install it like a normal rpm package:
sudo rpm -Uvh android-x86-7.1-r3.x86_64.rpm
This will update your older installation like 6.0-r3 or 7.1-r2 if you have.
On a deb based device (Debian/Ubuntu/LinuxMint/...), please use the alien tool to install it:
sudo apt install alien
sudo alien -ci android-x86-7.1-r3.x86_64.rpm
All files will be installed to the /android-7.1-r3/ subdirectory and boot entries will be added to grub2 menu. Reboot and choose android-x86 item from the menu to boot Android-x86. Alternatively, you can launch Android-x86 in a QEMU virtual machine by the installed qemu-android script:
Note Android-x86 running in QEMU and the real machine (after rebooting) share the same data sub-folder.To uninstall it :
sudo rpm -e android-x86
sudo apt-get remove android-x86
repo init -u git://git.osdn.net/gitroot/android-x86/manifest -b android-x86-7.1-r3
repo sync --no-tags --no-clone-bundle
