Currently Progress :

Armhf : Booted into halium-boot.img , every function is not tested and facing error...

Arm64 : building required Halium-boot.img & system.img...

[Kazuma]

Hi all,

Halium-9 has some special items :

1. Seems Erfan's GSI only support ARM64 kernel & system, but I'm still trying if arm32 can do
2. halium-install for halium-9 seems have problem while halium-7.1 didn't face before, so If anyone have faced before, let us know, thanks!
3. in Halium-9, need use the halium-boot, not the hybris-boot

[Kazuma]

Decided to use Arm64 to do:

Repo URL : https://gitlab.com/j6primelte-halium

Thanks!

Status :(Sorry these days I'm out of work and didn't take care on this,sorry )

[Arm64]

1. checked some folder can't mount , including /vendor, cause necessary library can't load.
2. the lxc-checkconfig seems have some missing items
3. Confirmed U5 version of samsung stock source have touch panel problem by recovery environment validated, so need to find another source to use.

[arm32]

1. AFAIK, if it boots, it'll reboot once for unknown reason...
2. check /vendor is mounted (better than arm64 we found)
3. seem someone in telegram group is booted into GUI with container started, but have many driver on phone equipped can't use.
   Need Verify :
   i. what the source (KT/DT/VT) he used
   ii. if source is used, what parts is he modified, and whether modified in source reflect on building, and verified it's really usable
   iii. need to check everything parts in test required item is okey...
   iv. if i~iii is ready, should let the issuer reply on Halium github with progress about arm32 things.

@kazuma Hello... Just got Galaxy J6 phone and want to use Ubuntu touch on it, as I do not like other operation systems. Is it safe and how do I do it? Can you advise, please? Thank you Kazuma...

@linguamundi
Here is probably the best place to start if you want to help the port going further.
No need to ask the same question all around the forum, answers won't come faster and it doesn't help to get the information scattered between different threads.

@kazuma This is amazing porting, I have Samsung J6+ too, But you have an any GitHub repo? I maybe help you to porting.

[G1ott1]

I'm willing to try your port to my J4+. What should I expect?
