Upgrade RemixOS 2.0.205 to 2.0.403, MANUAL procedure possible?

[Vincent Cojot]

Hi everyone,

First, I'd like to thank the teams behind RemixOS and Android x86 for making this possible.

This is a very welcome addition to my toolset of recovery options for my personal use.

I have both RemixOS 2.0 and 3.0 working fine in VirtualBOX on Linux.

My problem is that the RemixOS 2.0 VM is unable to update to the latest 2.0 release.

More specifically, my 2.0 VM runs 2.0.205 and when I attempt to 'Reboot and Install'

(see screenshot #1), I am greeted with a warning that says:

"RemixOS was not installed properly using the Remix OS Installation Tool..."

I installed 2.0 using the DVD iso image.

If I attempt to proceed anyway, my VM reboots and comes back without any update being performed.

I have the 2.0.403 ISO (Remix_OS_for_PC_64bit_B2016071101.zip).

Is there a way/tool to perform a manual update?

Thanks,

Vincent

If the data.img can be saved, copy it and paste it to an empty folder. Uninstall the Remix OS 2.0 VM, and download the .403 VM. Try to plug back in the data.img after setting up the new Remix OS 2.0 VM

(I do not have VMWare, so I don't know if this will work)

Hi Dondre,

There isn't a data.img per se.. The VM has a single virtual disk.

That disk has a single partition of type 83 (Linux).

Inside that partition, which happens to be mounted under /mnt,

there's a /mnt/android-2016-04-20 directory (I assume it matches the RemixOS 2.0.205 release that I am using).

Also, it appears that there is a /mnt/android-2015-04-20/system.img file loopback mounted as /android/system.

/android itself is of type tmpfs and pretty much empty.

Since I am familiar with Linux and not so much with RemixOS, I'm just asking if there is a way to execute

the upgrade process manually from 2.0.205 in debug mode.

My 2c,

Vincent

Done, and happily running 2.0.403 on my VM.

Here's how I did it:

1) Mount the DVD ISO image under /mnt and copy system.sfs elsewhere:

# mount -o loop Remix_OS_for_PC_64bit_B2016071101.iso /mnt

# mkdir /tmp/rebuild

# cp -a /mnt/system.sfs /tmp/rebuild

# cd /tmp/rebuild

# unsquashfs system.sfs

# mv squashfs-root/system.img /tmp/rebuild

At this point, you can pause and root system.img or proceed with the injection.

The current directory should be similar to this listing:

# ls -la

2) With the VBox VM turned off, mount its HD using 'nbd':

# modprobe nbd max_part=16

# qemu-nbd -c /dev/nbd0 /shared/vbox0/VM/RemixOS_2/disk1.vdi 

# mount -t ext4 /dev/nbd0p1 /mnt

3) Inject the new (2.0.403) files into that filesystem:

# rsync -avP  system.img initrd.img kernel ramdisk.img /mnt

4) Cleanup

# umount /mnt

# qemu-nbd -d /dev/nbd0

5) Reboot your RemixOS VM and enjoy.

Tested using 2.0.205 (upgraded to 2.0.403).

My 2c,

Vincent
