It's ok now ! ( my girlfriend have now a dual boot with ubuntu on her computeur and it was easier )
I write this from the phone you ported ! I hope you will find a solution to fix the audio call bug. I will check others fonctions.
It's very sad that you can't use your galaxy note 4 anymore cause the network support in US.
Thanks for this port.
you unlock device as usual (enable developer mode, authorize your PC for USB debugging, boot into bootloader do fastboot flashing unlock)
Then, do not try to install TWRP permanently. You will have to boot it everytime with fastboot boot twrp-xy.img
You can select the slot to flash to also with the fastboot command. What I did was:
Boot TWRP in slot a
Install LineageOS 16.0 (to get the vendor partition), TWRP will install it to slot b!
Flash halium-boot.img to slot b
Install rest of system with halium-install. You also need to specify flag -s to install it with "system-as-root" mode
System is booting now, but recovery cannot be installed ATM with Halium. We are doing work now to integrate our recovery properly, at least then you will be able to use it.
@dytract well give it a try, but modding the image is already halfway to do a real port 🙂 you will need the Android build tree and such, so if there is a Lineage 14.1 or 16.0 for your device, I would still suggest you start a port.
Since my Zenfone2 is collecting dust in my drawer and I don't really plan to use it anymore:
I am willing to send it for free to any developer that is seriously interested in porting UT to it.
It is the 64GB, 4GB RAM version currently with LinageOS 15 or 16 (last official release, not sure) installed. Battery isn't the best anymore and the camera glass is a bit scratched.
To keep postage costs low I would prefer someone that lives in the EU.
In order to port Ubuntu Touch to your device, we need the android AOSP kernel with all specific modifications to talk to the various hardware components.
I don't know if there is a way to get those sources from elsewhere, but Cyanogen or Lineage guys achieve to get it, so there is a way...
Anyhow good luck. And maybe someone here can see your post and know a better answer.
