Xiaomi Redmi 4X (santoni)
-
@linuxadopter Not so much people reported issues, but so far I think the port could be usable for now.
Aside from loudspeaker mode in calls doesn't route to the speaker properly and a few apparmor issues.

Dual Boot -> Sysadmin approach :)I am using right now dual boot stock fw / ubport - switching boot from TWRP.
I write down thees steps to my self to remember and for everyone ho would like to try...
Using stock because is good... (dm-verity, rooted , ad-aware .... ) , I could not find any rom with scheduled Power On/Off feature. Needed a solution without wipe. As I understand won't mix the stuff because rootfs.img and system.img is used on ubuntu touch so it will be separated.So try ubuntu for freedom:
Having already an unlocked Redmi4x, with working StockRom, rooted, dm-verity, and TWRP installed.-
Boot to TWRP recovery, Backup ALL stuff including DATA.
-
Copy TWRP folder outside from the phone , ex. to Your desktop.
-
Format Data, to remove encryption, otherwise ubport installer won't work.
-
Copy back the TWRP folder backups to phone and restore stock rom.
-
Fingerprint and unlock won't work so need these steps in recovery mode:
Mount Data, System, and Delete from '/data/system' folder: files with .key extension and files with 'locksettings' keyword. Reboot to system. Everything should be fine , setup up again a security pattern. Fingerprints works after that.
-
Reboot to recovery and Backup stock Boot partition.
-
Backup to fasboot , flash halium-boot.img.
-
Reboot to Recovery, so ADB recovery is active , flash from Your Desktop:
path/to/halium-install -p ut path/to/rootfs.tar.gz path/to/system.img -
Backup Hallium boot partition.
Now You can switch any time , just restore Boot partition. Enjoy
.

@aceclan can u explain detail how to flash system.img from twrp?
-
@4htet , if You read again the steps I wrote:
- Reboot to Recovery, so ADB recovery is active , flash from Your Desktop:
path/to/halium-install -p ut path/to/rootfs.tar.gz path/to/system.img
Explain:
When You are in recovery mode and connect the USB cable, the ADB recovery mode is active. (I suppose You already have android SDK, ADB , fastboot tools...)
To check use command:
adb devices
in fastboot :
fastboot devicesso in this step won't flash from TWRP GUI, just use TWRP for adb, and reboot.
How to flash, was specified already by @Danct12 , read here:
http://docs.ubports.com/en/latest/porting/installing-16-04.htmlthe basic is ->
path/to/halium-install -p ut path/to/rootfs.tar.gz path/to/system.img,Best regards,

@aceclan Thanks for your reply. I followed your instructions. Now , when the terminal tell me to set password, this message is showing continuously. "chroot: failed to run command 'passwd' : Exec format error failed, please try again"
Edit: Now I know that I cant chroot into rootfs on my redmi4x which means qemu-user-static is not working on my Ubuntu 19.04. Still can`t find the fix for that.

Hey, I'm having some problems getting my 4X to boot into UT. I'm on Ubuntu 18.04 and downloaded latest System and Boot image from the Github. I also unlocked my bootloader and flashed newest TWRP. After that, I flashed Halium-Boot through fastboot. After booting back to TWRP( to get ADB to work) I started normally flashing with halium-install.
Everything seems to be fine. It asked me for password and flashed system and rootfs to /data. After that while trying to boot the OS, it just locks up on Mi Logo and on dmesg -w I see:
Here's the last message from Halium-Install:
I really don't know what's the problem here. I tried reformatting /data, /system, /cache etc. and same results, I also tried installing LineageOS 16 (Official) and install ut on top of that but still the same thing.
Any help is appriciated! -
@BlackOtton Well you are in emergency telnet mode, maybe you should use telnet to connect to the shown IP and see what dmesg says there ^^
-
@4htet Make sure
qemu-user-binfmtis installed on your host. -
@BlackOtton Is your data partition f2fs? If it is then change it back to ext4.
-
@Danct12 Now booting on Ubuntu. Thx for ur help.
-
@Danct12 Thanks, reformatting /data to ext4 finally worked.
-
@4htet , I also had many problems with halium-install, I've spent a lot of time to figuring out , using manjaro linux ...
I've installed the : qemu-arm-static , binfmt-qemu-static, simg2img from simg-tools package
and changed a line in function setup_passwd() ,from "halium-install/functions/distributions.sh"
do_until_success sudo chroot "$ROOTFS_DIR" passwd $user to sudo chroot "$ROOTFS_DIR" passwd $useron the halium install script are described the dependencies:
"

Hello @Danct12 ,
Flashing again Your last build, Mon 09 MAR, without any wipe -> all my settings were kept, this is normal? This is a feature? ... because of user data is stored in santoni:/data/user-data/phablet ?
Another problem network interface from computer disappearing during the UB boot.
Appearing for a short time then disappear.
-
@aceclan
Resolved, flashed the anterior. -
@aceclan Your home directory should stay intact, I flashed my nexus 5 on legacy build with halium 7.1 build and everything worked fine.
-
I tried to log in to google account to sync my contacts. But at the log in page, keyboard is not popping up( not showing) . And one more thing, my language BURMESE letters are not showing in sms. Showing only square characters. I tried to install fonts and it is saying read only file system. Any IDEA?
-
Please help me i tried everything always stuck at mi logo, i formated the data and flashed it and still stuck at mi logo never booted to ubuntu. please someone provide step by step process
-
@4htet Keyboard not popping up at Google page is probably a UBports error, the same issue is on Oneplus 3.
And read-only file system, you can try
sudo mount -o rw,remount /to remount the rootfs as root.But your language issue is weird, it could be a UBports issue unless someone tested it on official supported device.
-
@bisaalz Format your /data partition as ext4.
-
Same for me, format data as ext4 does not help. I am unable get any logs,
dmesg -won PC does not show anything,/sys/fs/pstore/console-ramoopsfile does not exist. I am unable to boot your recovery,sudo fastboot boot recovery.imgshow only mi logo. I tried to downgrade firmware, compile system by my own, many recovery images. But I am unable to boot this (and recovery from that post too). Some people on XDA have similar problem. I was using lastest MIUI 11.2 before.
