Hi. I want to start working to upgrade the Nexus 5 to focal.
I already found a kernel in progress for halium 9, which according to Florian's information cannot be compiled.
I found these two repositories.
https://github.com/ubports/android_kernel_lge_hammerhead/tree/halium-9.0
https://github.com/ubports/android_device_lge_hammerhead/tree/halium-9.0
The last activity on both repositories is a year ago.
If anyone has any additional information or notes from previous attempts, please post them here.
If anyone else on this phone is actively trying to upgrade to halium 9 and focal, please post here. We can share efforts to get a successful outcome.

Hi. Some time ago I tried to create a client based on libpurple. Xmpp support would be a matter of course there. Unfortunately, I don't have much time to devote to this project. But if by chance someone has the time and mood: https://gitlab.com/x_Dub_CZ/zetaim

I use a 128GB SD card formatted to FAT32.

According to this thread on XDA, it looks like the MAC address is stored in /efs/wifi/.mac.info.
Maybe this could help fix the problem.

Hi, I don't know about the others, but at the moment I have no way to use Facebook messages on UT.

And what about creating an app based on libpurple libraries?
It had occurred to me before, but I knew it would be a lot of work.
Something like this:

Libpurple can do a lot of protocols, including Facebook:

@povoq This client would allow this.

@odo Hi. I don't know if my answer will be relevant. Do you have FAT32 or exFAT on your SD card? I have the same phone and when I flashed UT on it, I also had problem with a SD card. FAT32 didn't work for me for some reason. But if the SD card is formatted to exFAT, it works without a problem.

I don't like creating zombie threads. But I would like to ask when to expect carddav support in UT? :beaming_face_with_smiling_eyes:

Bluetooth works well on my phone (Asus Zenfone Max Pro M1). The file /etc/bluetooth/main.conf looks like this:

Maybe it will help you.

Hi, I found the correct configuration file and were able to fix this error:

warning: (ANDROID_DEFAULT_SETTING) selects NETFILTER_XT_MATCH_QTAGUID which has unmet direct dependencies (NET && INET && NETFILTER && NETFILTER_XTABLES && NETFILTER_XT_MATCH_SOCKET && NETFILTER_XT_MATCH_OWNER=n)

Unfortunately, the "make halium-boot" command ends with another error.

Does anyone know what to change so I can continue?

I decided to rewrite the original post and include information about the phone.

There is an even "newer" version 2 on the market, which has exactly the same specifications. KingKong mini 2 differs only in the Android version (Android 10). It is likely that with version 2 it will be possible to downgrade to stock Android 9.

I have Device, kernel and vendor available for the port: https://gitlab.com/x_Dub_CZ/cubot_kingkong_mini-d936p

Halium 9 for Cubot King Kong mini?

Hi. I'm trying to create a halium 9 for Cubot King Kong mini.
Device, kernel and vendor: https://gitlab.com/x_Dub_CZ/cubot_kingkong_mini-d936p
The "make halium-boot" command ends like this: https://pastebin.ubuntu.com/p/k8w5XMVJ2K/
Can anyone advise me what I'm doing wrong?

@aimar : Yes, that's why I had to replace the display. I'm quite sorry, the phone looked better without the bottom painted buttons.

I use a 128GB SD card formatted to FAT32.

I would just like to announce that my Aquaris E4.5 behaves exactly the same. Although I originally thought that the non-original display was to blame. I changed the display roughly at the same time as OTA16. The touch decoder broke in the original display.

Some news?
