(2020/05/20)

The Android-x86 project is glad to announce cm-x86-14.1-r4. This is the fourth stable release of Lineage OS (formerly CyanogenMod) 14.1 porting for Android-x86. The prebuilt images are available in the following mirror sites:

Key Features

The cm-x86-14.1-r4 is an update of cm-x86-14.1-r3. It's based on the Android-x86 7.1-r4 and the latest LineageOS 14.1.

Released Files

The release contains these files. Except the images built with kernel 4.9 as before (the first four files), we also provide experimental images built with kernel 4.19 (the last two files). If you have newer devices not supported by kernel 4.9, you may try the kernel 4.19 version. Most modern devices should be able to run the 64-bit ISO. For older devices with legacy BIOS, try the 32-bit ISO.

You can choose one of these files depends on your devices. In doubt, try the 32-bit ISO for legacy BIOS devices and 64-bit files for UEFI devices.

To use an ISO file, Linux users could just dump it into a usb drive to create a bootable usb stick like :

dd if=cm-x86_64-14.1-r4.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.

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 cm-x86-14.1-r4.x86_64.rpm

All files will be installed to the /cm-x86-14.1-r4/ subdirectory and a boot entry will be added to grub2 menu. Reboot and choose cm-x86 item from the menu to enter the system.

To uninstall it:

sudo rpm -e cm-x86

On a deb based device (Debian/Ubuntu/LinuxMint/...), please use the alien tool to install it:

        sudo apt install alien
        
        sudo alien -ci cm-x86-14.1-r4.x86_64.rpm
