The parents of the smiling emoji are B and a closing parentheses. (I mean I typed these two characters.)

@stanwood Thank you for the detailed description.

I followed the method (manual installation) on a Xiaomi Redmi Note 9 Pro.

apt update run with several error messages,
after that everything went smoothly,
except the last command: there is no anbox.conf file, there is no gbinder.d directory at all.

Can you give me any hint?

Thank you in advance.

For anybody interested in this thread…

The post at 29 Sep 2022 15:47 has been edited; thank you, Jakub.

Now this answer (at 29 Sep 2022 15:47) seems to me complete.

Do not read my question below (29 Sep 2022 16:59); it is now irrelevant and will confuse you.

@jakub

Thank you for your quick answer.

I cannot understand one particular detail.

1

If the phone arrived with Android 9, it is OK.

2

If it has newer Android, I have to downgrade to Android 9, link somewhere in the thread,

3

But as far as I understand you gave a rom version for Android 10.

Do I need it for a later upgrade (Android 10 -> downgrade to Android 9 -> upgrade to Android 10 with the above mentioned rom)?

Sorry for my misunderstanding. I like linux and I have been using it for about twenty years, but I have no experience with Android phones… I had Nokias, then only Ubuntu ones…

Thank you for the step by step instruction.

I am in a similar situation: I bought a new Xiaomi Redmi Note 9 Pro. It is in the original package: it has not been used until now.

As I understand from the detailed description above:

1

I must start the phone with Android and I must personalize it with my google account.
It is needed to create a Xiaomi account.
It is not necessary to upgrade Android if it is Android 10 (I hope it will be).

2

I can and I must download the Mi unlock App.
Did you really mean 155 hours, ie is it a week long process?

3

As far as I understand Android 9 (anything earlier than Android 10) must be upgraded, it happens by installing a new rom.

4

I hope I understand well the above written steps. My most important question:
If I have Android 10 on the phone (no need for upgrading Android), then

a)

do I need the Xiaomi program to flash my phone, do I have to download for Windows 10 MIUI ROM Flashing Tool etc…

b)

or I can continue with installing adb and fastboot on the pc… etc

Thank you in advance.

@badcloud
I have not found any detailed description about it.

I made some alternative layouts: the number of buttons was changed, the layout of the keys was redesigned, but I cannot (and do not want to) add Ctrl, Alt etc. It might be interesting, but it is far from my understanding the device and the operating system.

My only purpose was to make it easier to reach the full Hungarian character set and some typography marks (and to make it easier the full ascii set in another layout). After that I made layouts for several other languages for my fun only.

Well, to tell the truth, I sometimes suffered from the French keyboard layout and I thought it would be much more comfortable in a hotel when my design would have been universally accepted:-)

You can find two scripts for installing these layouts. You must reach your device with ssh, you have to adapt its ip address, there may be further little quirks… Your measures may vary, elementary bash knowledge is necessary to edit (and then to use) the scripts…

There is a simple backup mechanism for the original files, but no guarantee is given. After trying my scripts your device may be unusable, the keyboard may disappear etc.

The scripts were successfully used on bq Aquaris E4.5 phone, M10 tablet (original Ubuntu from Canonical) and on bq Aquaris E4.5, Nexus 5 phones (recent Ubuntu Touch).

pglk is for p(h)oenician, greek, latin and cyrillic alphabets
or simply
p(oly)gl(ott) k(eyboard layout)

Enjoy it…
