unable to install on poco f1

MrT10001

@audrew Ok, I assume you have unlocked the device and it was originally running Android 9 (or it wouldn't run flashing firmware).

You may have an old version of ADB tools and Fastboot. They need to be up to date (I install Android Studio on Windows 11 to give me the latest versions).

Make sure the device is disconnected after the "flashing Firmware" part, it should pause and enable you to disconnect the device, power it off, wait a few seconds and then press Volume Up and Power Button together - wait till the device switches on then release the power button but keep the volume button down till it gets to the recovery screen. Plug the device back in and continue the installation.

Download and Install the Ubports Installer from here: https://devices.ubuntu-touch.io/installer/
Put your phone in fastboot mode (Power + Vol Down) and connect.
Open the installer. The device should be recognised automatically.
Read the Warning and Follow the onscreen instruction.
You will be needed to put your phone into recovery mode in between. Once installer copies all the files, the phone will automatically reboot into recovery again to install the OS. Finally, it will reboot into Ubuntu Touch automatically

@mrt10001 Sir, fastboot and adb-tools is latest. I will try to check if adb devices is available before running ubports. But maybe there is other way to do it manually because it doesn't seem to work.

Hi Audrew,

@audrew said in unable to install on poco f1:

Sir, fastboot and adb-tools is latest. I will try to check if adb devices is available before running ubports. But maybe there is other way to do it manually because it doesn't seem to work.

To determine if the Android device is reachable, enter the following command in the terminal:

adb devices

If adb has not been used in the current session, the terminal will first report the start of the adb daemon, then, if all goes well, something like

* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached 
5200d6fd904b2200 device

If there is only an empty line after List of Devices attached instead, the device is not reached (yet); check in the USB connection settings on the device if "Load only" is selected. If unauthorized is displayed instead of device, the connection has been established, but must be confirmed on the device; to do this, confirm permanent access in a message displayed on the device. If recovery is displayed next to the device number, the device is in recovery mode.

Please check and let us know.

Greetings

@audrew
What is the OS on your PC ?

audrew

@keneda linux ubuntu

@audrew
Ah ok.
Can you adb device from pc when it is booted in recovery ?

@keneda no

MrT10001

@audrew either you don't have the correct/latest or no ADB driver installed, or your usb cable is faulty. Also try another usb slot on the pc, preferably not usb 3.

audrew

@mrt10001 I did correct installation on nexus 4 with same usb. I just also tried another usb even though one is working too. nothing changed

@audrew
Here what i can tell you, but i did install on my mx4 using windows 7 so it surely differs from ubuntu.

I asked you for the recovery thing because my mx4 ubports installer install always issued the same exact moment each time i tried, untill i understand that on windows, my device was 3 separate devices in device manager for every boot mode, one device was normal boot, for wich i had to install (or link) adb drivers so that ubp installer auto detect device, one another device was when i connected my mx4 in fastboot, another adb driver link needed here to allow installer to reconnect to device after rebooting it from normal to fastboot, and at least, one last adb driver link when booted in recovery, so that ubp installer can continue to "talk" to device after rebooting it from fastboot to recovery, and finish install.

So best is to boot device in normal, link adb driver, then reboot fastboot, link adb driver again, and then reboot recovery, and do the last adb link, and then you can reboot in normal, launch ubp installer, and plug usb then device recognised and install is auto from beginning to end.

Again, that was under windows, with a mx4, and i have no clue how unbutu or linux desktop handle drivers install and link to devices, so maybe your issue is not the same or same origin, but, my two cents here ^^

@keneda I tried to find manual to install it via twrp, I get official system.img boot.img of ubuntu touch. But probably not all files was correct and it doesn't boot. Maybe anyone know any article about that?

MrT10001

@audrew Check here. I would still recommend the Ubports Installer as they do.

@mrt10001 out artifacts link is broken

@audrew It's an old post, but should give pointers. Don't take it "as is", but use it to help solve issues.

If you have an ADB error, you have to do basic troubleshooting i.e.:

Change USB cable
Change USB port
Try another PC
Update ADB drivers
Clear space on your PC
Install TWRP and format data partition and make sure it is formatted to EXT4
Wipe the system and Cache partition
Reinstall the correct stock ROM, but DO NOT relock the bootloader (you have to use a windows PC for Xiaomi phones and use the Mi Flash tool) and start again.

One USB cable may work on one device, but not on another.

@mrt10001 as far as I know adb shoudnt to be detected in fast boot mode. Or it should? Every time I try to install ubuntu, boot data is erased and the ubuntu touch is not installed. So basically I have to rewrite back android and try again. It is very tedious

MrT10001

@audrew ADB is like a higher level of Fastboot. Basically ( please feel to correct me anyone) fastboot installs a boot image and a recovery image. The boot image allows UT to boot, but you usually have to manually boot to recovery. Once in recovery ADB is then working and the UT install will continue by pushing the UT files over it from the PC to the device.
A bad or incompatible USB cable will stop ADB from functioning so no UT install.
An encrypted data partition will stop an install and can be flagged as an ADB error, that is why you have to format the data partition to EXT4 and wipe it so it is decrypted.
If the partitions have been resized, usually by installing a non stock ROM such as Lineage OS, UT won't install and may give an ADB error.
A bad or USB 3 port may cause an ADB error.
A PC/laptop may cause an issue for various reasons, if UT won't install on Windows, try a Linux based machine or a MacOS based machine.
Try an older installer, the latest Ubports installer may be a bit buggy.
Also follow the installation instructions to the letter or the install usually fails. Try a different channel if the stable channel fails to install.
