Porting Ubuntu Touch (@UBPorts) to karin (Sony Xperia Z4 Tablet SGP771) and karin_windy (Sony Xperia Z4 Tablet SGP712)

Guf

@ignne I read somewhere that karin's chipset works as rome one so that it can be backported, as experienced by some xiaomi porters. I need to find some time to apply patches and try to backport for better compatibility with blue 5.x or later

My install for karin (SGP771) was succesful with these instructions. Thank you.

Based on the feature list above, Anbox is supposed to work. What is needed to achieve this? The device is not officially supported and the image does not seem to work for that purpose as such:

phablet@ubuntu-phablet:~$ anbox-tool install
Anbox kernel is not installed! Please flash this first!

Also, how can I update to the OTA-13 release?

stanwood

@masa I guess that you first have to flash the image as described in the first green box here: http://docs.ubports.com/en/latest/userguide/dailyuse/anbox.html
Than you can install anbox tool & APKs
Read carefully the previous guide. Installing Anbox is only recommended for experienced users.

masa

Thanks @stanwood. But what would be the variable CODENAME in the green box you mentioned? I mean is an anbox image available for this device as supposed in the documentation you linked?

Keneda

@masa
I guess your device codename is "karin"...

But in the "Supported devices" for daily use from stanwood given link, there is not your device (nor mine, wich is MX4 a.k.a. "arale").

It is not listed here : https://cdimage.ubports.com/anbox-images/

@masa I worked for me with the following instructions:

sudo apt install anbox-ubuntu-touch
mkdir anbox-data
wget -q --show-progress -O /home/phablet/anbox-data/android.img http://cdimage.ubports.com/anbox-images/android-armhf-64binder.img
touch /home/phablet/anbox-data/.enable
mkdir anbox-data/data
sudo chmod -R o+wrx /home/phablet/anbox-data/data
sudo start -q anbox-container
start -q anbox-session

at this point, you need to reboot twice!
Respect the official instruction, it seems to work for me the wget command without using sudo

Guf

@Keneda Don't worry about that: information might not be up-to-date

Guf

@masa This list if for legacy and official supported device, rather than community ones (like karin is supposed to become soon).
Anyway it is not supported on kernel yet: anbox porting on karin is on going

@ignne yesterday, I got bluetooth work on my BCM43 devices. At the moment, manually:

Install / Preparatory steps xperia Z4 Tab

sorry for asking my question in this thread. But there are probably still too few xperia Z4-Tab users, so that I cannot get any answers in the support thread.

I am not successful in Preparatory steps 8 & 9. I can load and save the FIle SW_binaries_for_Xperia_AOSP_M_MR1_3.10_v13_legacy.zip but after unpacking I cannot find the file: SW_binaries_for_Xperia_AOSP_M_MR1_3.10_v13_legacy.img but a complete directory tree.
How can I generate the img file from it? Is the link in the instructions really correct?

I would really like to install UT on my tablet (and also test it), but unfortunately I already fail in preparatory steps 8 & 9. Please help me, because I assume that you have successfully install UT on your Z4-tablets.

Hope for Your help ...

P.S. Thanks for porting this tablet, because I'm a ubuntu user for over ten years....

@z4tab actually I never performed these preparatory steps, so I can't help you out. My suggestion is to unlock bootloader and install twrp, then from there (recovery mode) try to activate adb sideload from twrp menu on device and on pc's terminal execute adb sideload name_of_binaries.zip.
If you want to risk to go directly on installing UT, first try to install it on datapart (the /data partition) with halium-install. Remember to use the proper halium-boot.img.
When you will be more familiarised with UT and recovery also in systempart (/system partition).
