Installation UbTouch Ko

[Markatrafik]

@stanwood Yes...
Of course! I even made sysmlinks in /usr/local/bin as some people advised, included the user in several groups, e.g. dialout, all dependencies, adb and fastboot work, I flashed TWRP with this fastboot - fine, tried it from root as well, in short, provided it with everything ubports-installer needed, tried also the version that works via snapd according to these instructions:
https://snapcraft.io/install/ubports-installer/debian
and the ubuntu version with cross-installation of all the necessary packages:
ubports-installer_0.8.7-beta_linux_amd64.deb
The result is the same for all of them - a brick.

P.S. The installer finds the phone, identifies it as Lavender, does something fun with it... It downloads a lot of files it needs, flashes it, sends it to reboot and - bricked. I wait 15 minutes and nothing loads, maybe I should have waited a hour, it do somthing?
But it seems to me that every minute the "watchdog" was triggered and the phone rebooted, but I can't say for sure.

So, my phone bricked yesterday during installing, and stuck on boot screen. Is it repairable, mendable? or should I drop it to the recycle bin?

@magic
If on boot screen, not bricked.
In fact it is quite impossible to brick device with trying installing uTouch.

As i do not own this device i can't help you with installing, but no, do not bin it, you'll get help here, don't be afraid ^^

@whitemagik Bonjour, j'ai aussi tenté d'installer UBports sur un xiaomi redmi note 7. Il était sous android 10 malheureusement... (j'ai vu trop tard qu'il fallait le retrograder) J'ai bien réussi à le déverrouiller et le programme d'installation sous ubuntu 20.04 semblait se dérouler normalement mais blocage à Waiting for device... Adb is scanning for device.
L'appareil est bloqué sur la page d'ammorçage d'Android. En maintenant power et son- il boot sur Fastboot mais impossible de l'éteindre.
Que faire ? L'un d'entre vous a-t-il une solution ?

Hi, please note that this forum is in English only.

As a french speaker myself, I just did translate your message in English as follows:

*Hello, I also tried to install UBports on a xiaomi redmi note 7. It was under android 10 unfortunately... (I saw too late that it had to be downgraded to Android 9)

I did manage to unlock it and the installation program under ubuntu 20.04 seemed to run normally. But suddenly it gets stuck on the error message: "Waiting for device... Adb is scanning for device".

The device is stuck on the Android boot page. Now, when I try to turn it back on by holding the "power" and "volume +" keys it starts in Fastboot mode, and moreover it is impossible to turn it off.

What can I do? Do any of you have a solution?*

[stanwood]

As you well explain in your message, I strongly suggest you to downgrade your version to Android 9, and then try again.

[jmla]

@stanwood Thanks, but how do you reflash android 9 now that everything seems stuck?

[jmla]

@jmla I think the installation of ubport could be good if i can install ADB 1.0.41on ubuntu 20.04. But i don't find link for it.

[Josele13]

@jmla I had android 10, the Ubports installer took care of everything, it downloaded the android 9 image and then installed ubuntu touch, important is that you don't have encrypted data, you would have to format it.

@josele13 hi, i managed to unbrick my redmi note 7 via test point mode, which requires rear window removal and MiFlash in authorized mode. that is done !
Now, I installed android 9 but after 2 attempts to install ubport, it still hangs on Waiting for device Adb is scanning for device.
However, the smartphone is in developer mode, OEM unlocked, USB debugging enabled and allowing USB downloads. I checked the unlock with miflash_unlock.
The PC is under ubuntu 20.04.
Does somebody have an idea ?

[jmla]

@magic
hello, did you manage to get your phone back? Otherwise I can give you the procedure under windows 10.

[Josele13]

Have you tried using the ubport snap installer? I was only able to do my install with snap, appimage and .deb failed, I remind you that DATA should not be encrypted, try booting the phone in recovery, connect it to a usb 2 port, I usually open the terminal and see if the computer recognizes the phone correctly, ........ sudo adb devices, if it recognizes it puts a number and then start the installation with the installer ubports, mark wipe data when that option, that's the normal thing to do installation,

regards...

[jmla]

@josele13 Indeed, ADB does not recognize the telephone: sudo adb devices does not give anything.
How to cure it ?

[Josele13]

@jmla On the phone with android on .... developer mode on, usb debugging also, when you connect it to the PC on the phone appears on the screen a pop-up window, it put allow usb debugging, press YES, now you can put the phone in recovery, connected to the PC to a usb 2.0 port ...open the terminal and put ..... sudo adb devices, you should see a numbering ...... 45xx541 devices ....for example, this indicates that adb works and the phone is recognized by the PC, now turn on ubport installer and install UT

I remind you that fastboot has to be installed on the PC, it is necessary for the installation, when the installation starts the phone switches to fastboot.

Regards...

My installation failed too.
(i have Android 9 installed)

1. enabled developer mode
2. enabled USB debugging
3. connected to PC
4. rebooted to FASTBOOT screen
5. started UBports (in Ubuntu linux)

And this error message occured:

Error: fastboot:format: Error: formatting failed: Error: {"error":{"code":1,"cmd":"fastboot format system"},"stderr":"FAILED (Status read failed (No such device))\nfastboot: error: Command failed"}

What happened here?
