Asus Z00A - Zenfone 2 ZE551ML Z00A



  • @aalavandhaann
    Did you make any further progress on this?

    I researched a bit and it seems like the Kernel used is actually 64bit x86, just the Android "around" it is 32bit. Thus unless Halium forces 32bit as well, it could be really interesting to get a full 64bit OS finally for this great phone.



  • Hi there, you could try this manifest:

    <?xml version="1.0" encoding="UTF-8"?>
    <manifest>
    <project path="device/asus/Z00A" name="android_device_asus_mofd-Z00A" remote="los" />
    <project path="device/asus/mofd-common" name="android_device_asus_mofd-common" remote="los" />
    <project path="kernel/asus/Z00A" name="android_kernel_asus_moorefield" remote="los" />
    <project path="vendor/asus" name="proprietary_vendor_asus" remote="them" />
    </manifest>
    

    Note that according to the official haium docs it's recommended to fork or clone all repos to a personal repo, then adding those personal forks to the manifest. 😉

    Hi what do you mean for "around" ? The halium build tools ?

    No, I was referring to the original Android shipped on the Zenfone2 which has long been lamented for being 32bit, despite having a SOC that was advertised as 64bit.



  • @poVoq hmm ok this is for the original android os right? so this still apply to lineageos 14.1 ? I'm sure that the kernel of version 14.1 operates in 64bit mode but I don't know if the userspace is in 32 bit mode.



  • Yes it also applies to the latest LinageOS. So it must be the user space mode (?) That is 32bit only.

    Would that make running apps build for amd64 impossible when wrapped in Halium?



  • as long as the kernel is 64 bit I think there should be no problems. What do you think about it?

    Yes maybe. But I wonder if there might be closed source user space android drivers or such that would force UT also into 32bit mode? Sadly the Zenfone2 has one of these pretty locked down GPUs.



  • Do you think that this phone with this kind of architecture could be a dead end?



  • It is already at a dead end when it comes to Android. If it would be able to run amd64 apps compiled for a somewhat theoretical x86 desktop version of ubuntu touch, then it would be probably fine for a few more years. But if it is really stuck in 32bit like on Android, then I think a UT port would not help.



  • Is the kernel really 64-bit? I've built LineageOS 14.1 according to their own guide and uname -m is reporting i686, not x86_64.
