Update for Remix OS installations

Update for Remix OS 2.0.x or 3.0.x systems which have been set up using the boot option INSTALL=1

Clicking "Settings > Update" (Remix OS 2.0.x) or at "System update" (Remix OS 3.0.x) will show that there is a new version of Remix OS.

With current version 2.0.402 you'll get the information, that there is a new version 2.0.403 (2016-07-12).

If you start "Reboot and Install" in a Remix OS system which has been installed using the boot option INSTALL=1 ( see "How to install Remix OS in VirtualBox (or to harddisk)"), the root terminal will show an error message after rebooting the system (typing <Alt + F1> after the restart):

Start updating...

ui_print Warning: No file_contexts

script aborted: /mnt/system.img has been remounted R/W; reflash device to reenable OTA updates

wait pidpid doneError in data/media/0/autoupdater/otapackage.zip (Status 7)

Update failed

So the update has to be performed using a current updated version (downloaded from Jide - in case that exists) or an OTA-updated USB device replacing the system directory with a new one and preserving the data directory.

Step 1: Boot your system with PartedMagic (like in "Installation on Hard Disk or VM" )

Start the "File Manager", and open the Remix OS partition (e.g. sda1)

- Delete all files and directories other than the old android directory ("android-2016-03-01" for version 2.0.102, "android-2016-04-05" for version 2.0.202, "android-2016-04-20" for version 2.0.205, "android-2016-06-30" for version 2.0.402, "android-2016-07-26" for version 3.0.101, "android-2016-08-03" for version 3.0.102, "android-2016-08-08" for version 3.0.103, "android-2016-08-11" for version 3.0.104, "android-2016-08-16" for version 3.0.201, "android-2016-08-23" for version 3.0.202)

- Rename "android-2016-08-23" into "RemixOS" for new version 3.0.203.

- Open directory "RemixOS" and delete all files and directories other than "data":

- Close the File Manager and shut down PartedMagic.

Step 2: Booting with your Remix OS USB drive (which is the current version or which has been OTA updated before - see OTA-Update USB Installation )

For updating a VM installation (Virtualbox or VMWare) you have to distinguish 2 cases:

- there is an iso file of the current version --> attach it as optical drive

- you have an USB drive only containing the current version --> attach the prepared usb.vmdk (see Tools ) as first entry to your SATA Controller:

After popping up of the Remix OS boot menu press the Tab key and change the boot options with "INSTALL=1 DEBUG="

Step 3: Remix OS installation

The installation begins with selecting the Remix OS partition. The image shows the 3 partitions of the USB device first (sda1, sda2, sda3), and the 3 Remix OS partitions (sdb1, sdb2, sdb5) below. The ext4 Remix OS partition is sdb1.

- Do not format your Remix OS partition (sdb1) because you want to preserve your data directory

- Install a new boot loader GRUB (the old one had been deleted because it pointed to the old android directory)

If you are updating a dual boot system, don't install GRUB (but you have to update the customized GRUB of your main OS - see below)

- Do not install EFI GRUB2

- Install a new /system directory as read-write (the old /system directory has been deleted in step 2)

- Run Android-x86 after the installation has finished

- After quite a while you'll see the message "Remix . . . Finishing boot" and somewhat later your old Remix OS desktop.

- You'll find a new icon "Install Apps" (see Google Play Store ), but you don't need it, because your Google Play Store is still working.

- Shut down Remix OS and remove the USB drive or the iso file which you have used for installation

Step 4: Finishing work

The grub directory and the system directory have been created newly. So all modifications concerning boot menu (see Hard Disk or VM Installation ) or rooting (see Rooting Remix OS ) have to be done repeatedly.

In case of a dual boot system (see http://xdaforums.com/remix/remix-os/how-to-install-remix-os-alongside-t3352890 ) the "Grub Customizer" of the main operating system has to be opened, and the path name of the android directory has to be corrected to "android-2016-07-12" for version 2.0.403 or to "RemixOS" for version 3.0.203)

Checking the version (with "Settings > Update") after a restart will show the new version. Your personal data and your old desktop have been preserved.
