@phandersson I have MiA2 with OTA 20 with 2 SIMS and it works for me. Available for more questions.

I have experienced that when using Bluetooth when WiFi is turned off the Bluetooth will also disengage despite it still is shown as On in the control bar.

Has anybody the same experience?

@keneda Thank you, but I have exactly that problem. Devices pair with no problem and work very well with music, but when I want to do a call the telephone disconnects the Headset . Connects again after the call finishes.

i had exactly same issue with a Xperia X.

I have updated to OTA 20 but the telephone still makes the same.

I have installed Ubports OTA16 rc in an MiA2 all good, really almost ready for daily driver and finally dump Android, as i indicated here: https://forums.ubports.com/topic/6933/mi-a2-installing-using-the-ubports-installer/8

I have only one problem on this way. Bluetooth works perfectly fine only that it disconnects during telephone calls (incoming and outgoing) it reconnects again after the call.

The software seems to recognize it as when it disconnects shows the speaker volume and when it reconnects it shows Bluetooth volume.

I had the same problem with a Xperia X in which I have installed Ubports also.

Additionally, to overcome this problem, in the MiA2 I have tried various USB C to headset converters, none works.

This means that hands-free in auto does not work (what would be the only impediment as a daily driver).

Has anyone had the same problem?

@keneda I have finally installed it I do not know what of this was crucial and what not or not but i put it all here for others to use:

Mobile was, after several failed installation attempts in a status in which it only could boot to Fastboot both Recovery and System did not work.

i have used a computer with Intel chipset running Ubuntu 20.04. Because in the computer with Opensuse Tumbleweed with AMD chipset it was not working and had led to previous status.
I have used a USB 3.0 port with a short (8 cm) cable USB A to USB C.

I have installed adb and fastboot using the following (the other ways did not work):

sudo apt install fastboot
sudo apt install adb

I have installed the Android 9 stock image in the way similar to what is described by @scream314, using the image on the link shared in his post https://forums.ubports.com/topic/6951/ubports-quick-and-simple-install-on-xiaomi-mi-a2 (thank you).

But

• used the 3.3.1-0 version of the TWRP instead. The one shared in the post did not work for me.

• Before installing I wiped and formatted the mobile as shown here: https://www.youtube.com/watch?v=sqmng9WQFkI&t=0s 9:11 minutes

• I also changed the slot manually between the installation in Slot A and B, in the reset menu of TWRP and I did not reset between the installation in slot A and slot B.

• Instead of using sideload I just copied the Image using the files App of Ubuntu and "copy to" as you would do to an USB stick. The Mobile will appear as an storage after formatting it.

After installing Android 9, i had to reset the mobile twice before System Android 9 could start and exercise some patience. I did the absolute minimum Android setup.

I enabled developer options and USB debugging.

(At this point, i tried to install then permanently TWRP in the Recovery (as indicated in the mentioned video), but it did not work, in fact I lost the Android 9 installation by trying to do it it and had to install it all again, but it was not necessary either).

Then I downloaded and installed the APP (0.8.9) in the computer, but not from the link in the device page (did not work) from the Ubuntu App store.

Then I have followed the instructions of the App with the following details:

Did not select Wipe Personal Data
Selected 16.04/arm64/android9/rc
(/stable did not work and brought the Mobile to a status in which I had to do everything again from the start).

After running Ubuntu for the first time,I forgot to install the SIM before and after Mobile Data could not be activated. I solved it by doing an "Erase and Reset All". So suggest do not forget that.

Hope it helps and thank you to all from which I grabbed info.

@jonlockwood17 I am using a Laptop (AMD Chipset) with Opensuse Tumbleweed. Thank you I will try with another with Ubuntu and Intel Chipset.

Interesting is that I have installed UBports to another mobile using this same machine (AMD Opensuse) and it worked without problems.

@keneda said in MI A2 Installing Using the UBports Installer:

@rosenfeldpj
I will be poor help for you but for others you could please tell what version of ubports installer you use ?

Anyway it seems to be a slot (A/B) finding issue in the log you provide.

Again, not a good help from me as i can't tell you how to select any slot.

Thank you, going to try.

@rosenfeldpj Thank you, it is version 0.8.9-beta

I have followed all instructions I have unlocked bootloader, downgraded to Android 9 using TWRP but the UBports Installer still gives an error:

Error: fastboot:format: Error: formatting failed: Error: {"error":{"code":1,"cmd":"fastboot format:ext4 system"},"stderr":"< waiting for any device >\nfastboot: error: Failed to identify current slot"}

Running from Opensuse Tumbleweed.

Help please?

Thank you in advance.
