Xiaomi Redmi 4X (santoni)

@aceclan I'm trying to understand this dual boot since I don't see any resize of any partitions.
Can you explain how that works ?
I understand you flash the boot image according to the os you want to boot, but where are located the two images of android and ubuntu ?

One question then: my TWRP folder only contains a .twrps file, is that fine ?

@Danct12 THANK YOU!
I've been wiping all the time instead of formatting. Now it works just fine

I'm trying to flash ut but I got this error:

./halium-install -p ut ./ubports-touch.rootfs-xenial-armhf.tar.gz ./system.img
basename: not valid option -- "p"
Try 'basename --help' for more information.

cleaning up

@danqo6 Can you try to upgrade the firmware to the latest? I use this https://xiaomifirmwareupdater.com

Danct12

@suoko Distro?

You should try this one instead: https://github.com/JBBgameich/halium-install

@Danct12
I successfully installed the version of ut found here : https://forum.xda-developers.com/xiaomi-redmi-4x/development/unofficial-ubuntu-touch-redmi-4x-santoni-t3982389
These are the steps:

rooted and installed twrp with Xiaomitool v2
in twrp I wiped the data partition and enabled write access to system
installed the zip via twrp

Now, how can I create an update zip package with the latest image?

suoko

@Danct12
I found a way to create the zip, tell me what you think:

download the unofficial zip from xda (see post above)
remove img files inside
download system and boot image from https://github.com/ubports-santoni/ubports-ci/actions/runs/52390878
rename halium-boot to boot.img
run this script

wget https://ci.ubports.com/job/xenial-rootfs-armhf/lastSuccessfulBuild/artifact/out/ubports-touch.rootfs-xenial-armhf.tar.gz
mkdir rootfs-build
dd if=/dev/zero of=rootfs-build/rootfs.img seek=500K bs=4096 count=0
mkfs.ext2 -F rootfs-build/rootfs.img
mkdir -p rootfs-build/cache/system
mount -o loop rootfs-build/rootfs.img rootfs-build/cache/system/
cd rootfs-build/cache/system && zcat ../../../ubports-touch.rootfs-xenial-armhf.tar.gz | tar xf -

put back the img files into the zip according to their original position: system and rootfs into data, and boot into the root position (the rootfs img is in the rootfs-build folder)

Thanks, it worked, I used the standalone version.

Recap:

https://github.com/JBBgameich/halium-install/releases
https://github.com/ubports-santoni/ubports-ci/actions/runs/52390878
https://ci.ubports.com/job/xenial-rootfs-armhf/lastSuccessfulBuild/artifact/out/ubports-touch.rootfs-xenial-armhf.tar.gz
fastboot flash boot halium-boot.img
halium-install-standalone.sh -p ut ./ubports-touch.rootfs-xenial-armhf.tar.gz ./system.img
ssh into it (ssh -l phablet x.x.x.x) and run:

cat /var/lib/lxc/android/rootfs/ueventd*.rc|grep ^/dev|sed -e 's/^\/dev\///'|awk '{printf "ACTION==\"add\", KERNEL==\"%s\", OWNER=\"%s\", GROUP=\"%s\", MODE=\"%s\"\n",$1,$3,$4,$2}' | sed -e 's/\r//' >/usr/lib/lxc-android-config/70-santoni.rules

Cons: neither system nor apps have sound. With the unofficial zipped port in xda at least apps had sound

Can we try create a script automating the creation of the flashable update zip ?

@Danct12 i am on android 10 rom
can i flash ub directly or i must flash Los 16 first?

danqo6

@Danct12 I tried, it didn't help. I will wait probably for ubports installer support, would love to see it soon

Hi @suoko ,

The switch is based on boot image flash (restore from TWRB th boot) and the Ubuntu is just two .img files : rootfs.img and system.img which will be mounted, during the boot. So the partitions won't be touched...
The locations of img files (browse from TWRP) is on /data/ , while the location of Internal storage that You see in MIUI is /data/sdcard or /data/media/0 .

Work like a charm...

Best regards

androxtar

Can anyone please add zip installation or Nandroid backup of ubuntu touch latest for santoni and maintain it (upload latest whenever ubt updates) for people out there who don't have PC and therefore can't install it. Including me.

Or any way of installing it without PC ?

@bablltioyv
Second this. At least one that's updated once in a while. Thanks in advance

Okay I tried both halium-install method and generating standalone zip based on @suoko instructions. Nothing works.

On the halium method, I'm stuck with
chroot: failed to run command ‘passwd’: No such file or directory
Failed, please try again

and installing qemu-user-binfmt did not help.

For standalone install, I followed @suoko 's instructions and made a zip file, which installed successfully, but it won't boot (stuck on Mi logo). I think system partition was not patched, because in one instance, TWRP reported "No OS installed, reboot anyway?"

Can someone suggest next steps?
