LGE Nexus 5 (hammerhead)

Flohack

This is an upgrade port for the Nexus 5 core device. The current port uses classic porting on Android 5.1 with lots of band aids and mixture of blobs etc. The new port is on Halium 7.1 level.

Install:
Assuming you have already Ubuntu Touch installed. That means, the bootloader is unlocked and a UT recovery is in place. You need a Linux PC with adb and fastboot installed.

You need the Android tool simg2img, e.g. from https://packages.ubuntu.com/xenial/devel/android-tools-fsutils or https://packages.ubuntu.com/bionic/simg2img
Download halium-install from here: https://github.com/JBBgameich/halium-install/releases (Click on Assets and download the standalone script)
Download the kernel and system image from here: http://twoot.bin.org.in/nextcloud/index.php/s/873qT7twZ6tXPqb
Download the latest rootfs image from here: https://ci.ubports.com/job/xenial-rootfs-armhf/lastSuccessfulBuild/artifact/out/ubports-touch.rootfs-xenial-armhf.tar.gz
Bring your device into bootloader mode (long-press Vol-Down and Power until bootloader menu appears)
Issue fastboot flash boot halium-boot.img
Select Recovery with the volume keys and confirm with power button
After device has booted, issue halium-install-standalone.sh -p ut ubports-touch.rootfs-xenial-armhf.tar.gz system.img
halium-install will ask for your host´s sudo password first. This is normal and no security leak!
Then it will also ask for an SSH/phablet user password to set on the device
Issue adb reboot

Now the device should boot into the new system.

Will this also include a Systemd / Wayland compatible Kernel?

Great work, @Flohack

Flohack

@poVoq Nexus 5 is on Kernel 3.4, so its not for the systemd that is in Halium (min requirement 3.10 I think). For wayland idk if there is any kernel dependency. However, we should take a look into whats the issue with systemd and kernel 3.4, maybe things could be backported a bit.

poVoq

I am guessing this will require a reflash of the device and will not come with a regular update at some point, right?

Flohack

@poVoq No it can be done with a normal update, but it will take some time to get confidence that it works. But we have everything on board to be able to flash this with an OTA

rob

Does this use the GPU? I noticed Video works here, though not on the classic.

Flohack

@rob Yes we hope to fix all video issues with this new upgrade. It should be also GPU-accelerated then.

My both N5 are running soo fine - u want to make them even better !? I thought only deepsleep was not working well.....

Great

Is this comparable or the same like this here from PostmarketOS: https://wiki.postmarketos.org/wiki/Google_Nexus_5_(lg-hammerhead)

And by the way: The list of potential devices is now soo long! You said something about 'easier porting with the next OTA'? Could it be that we will get all these new phones running during the next months?

domubpkm

@Flohack Very interesting !
Did you test hotspot and vpn editor ?

Flohack

@domubpkm Not now

@Flohack
Please will you update the Opening Post as things advance here...?

And will Halium 7.1 make convergence better on the N5? (Issue #301)

3 - eager as evvarh for the good stuff!

Thank you as always for the work done.

Flohack

@3arn0wl Yes the opening post will always be updated. I cannot speak much for convergence as I dont have a supported device, but lets hope it gets better

I am syncing the repo for this now, Ill see if any of the things I did for my Galaxy Note 4 will work on hammerhead

malditobastardo

Hello,
I know there has been some progress regarding the future of this device
Could someone please clear the current situation?
Thanks a lot!

Flohack

@malditobastardo Well we are working on a build based on Halium-7.1 which will improve camera and medai handling at least, and probably also solve other stuff. More important for us is that we reduce the number of code variants to be maintained in the future.

The build is still work in progress, currently fighting call audio, camera haha and some stuff. But it looks already nice. Still I wont recommend to flash it now, as basic things might not work as expected.

malditobastardo

@Flohack Thanks a lot Flo for your answer. Everything is very clear.
Keep up the awesome effort and just let us know when help with testing is needed.

kugiigi

I want to try this I am not much familiar with installing with just the sources. Do I need to compile them and install via TWRP? I have experience flashing via TWRP and nexus root toolkit.

Flohack

@kugiigi Please give me a few more days, the current sources and installation instructions are very unfriendly and will lead you in eventual problems. I will publish binaries so you can try.
