[ROM][AOSP][4.4/6.0/7.1] Unlegacy Android Project

Search This thread
nah it flashes fine but there is no supersu app, so i installed one and it says the binary needs to be updated but it cannot updates
The superuser app associated with that root option was supposed to be installed from the playstore. Since it's not there anymore, I've uploaded it to the same location. Maybe you could try that?

yo, doxts, i have a tab 2 7.0 which finaly got android 8.1, which has TI OMAP4430 but the GNEXUS has OMAP 4460, but the 4430 is "worse", why did it get android 8.1 but not the Gnexus (Samsung Galaxy Nexus) Is it going to come out
Afaik, it isn't really easy to port LOS for TI OMAP. Nobody had success for the Galaxy Nexus so far (also the project source is incomplete). You can try DivestOS which has the latest security patches.

    The Unlegacy-Android Project​
    Introduction
    Unlegacy-Android started out as the OMAP4-AOSP Project. It was created in late 2015 in order to maintain a clean and organized place for pure AOSP support for various OMAP4 devices, such as the Galaxy Nexus and the Samsung Galaxy Tab 2 series. Over time this evolved to support more than just these devices, but still maintains its roots of supporting "legacy" devices that no longer receive "official" updates: hence Unlegacy-Android was born.

    This organization's goal is not to create feature packed ROMs, but to create a base ROM in such a way that custom ROM developers can easily adapt the changes. We're good at (properly) fixing compatibility issues between newer Android versions and older devices, among other core things. The "bells and whistles" like themes we leave to others.

    The first public build here had something exclusive for the Galaxy Nexus, yet unseen on any other OMAP4 device: all RAM carveouts reserved for Ducati (the multimedia subsystem of OMAP4, responsible for hardware-accelerated video decoding, encoding and camera functionality) have been switched over to CMA.

    A few words for those who see CMA for the first time:
    The Contiguous Memory Allocator (CMA) makes it possible for device drivers to allocate big contiguous chunks of memory after the system has booted.
    The main difference from the similar frameworks is the fact that CMA allows to transparently reuse memory region reserved for the big chunk allocation as a system memory, so no memory is wasted when no big chunk is allocated. Once the alloc request is issued, the framework will migrate system pages to create a required big chunk of physically contiguous memory.

    This means that a total of 996 MB physical memory is available to the system, while keeping Ducati fully working - this is a huge step forward, coming from the 694 MB available in the last factory image released by Google (Android 4.3). This gives the OS access to an additional 300MB of RAM.

    While CMA was just recently implemented for this device, thanks to one of our developers (let's just call him Luden), it's quite stable: even under heavy memory pressure, the system manages to free up the required memory in order to start up Ducati and launch the requested multimedia functionality in a few seconds at most.

    Installation
    For Marshmallow (6.0) and below, It's important that /system needs to be unmounted before installing the ROM - some recoveries tend to leave it mounted after performing operations on it.

    If you're planning to install GApps, be sure to read the second post!

    Aside from these, installation and upgrading is no different than on other ROMs.

    Problems
    While we weren't able reproduce any CMA-related problems, hidden ones can still arise. In most cases, these problems will be either lost Ducati functionality (no multimedia capabilities) until rebooting, or a kernel panic (hard reboot) - upon noticing any of these, be sure to grab a logcat/dmesg and/or last_kmsg and send it to us (preferably by attaching it to a post in this thread).
    Other than that, these are bugs we're aware of in the current build:
    - The RIL on LTE devices (toro, toroplus) isn't fully working; calls and texts should be OK, but expect no data.
    - Sound pops can be observed, mostly when using touch sounds (this is being investigated)
    - Some exotic video formats or camera modes might not be perfect - if you notice any artifacts or green spots (the issue that happened in the past), report the details in this thread
    - Inverted colors mode not working
    - Tricky connection to some 5 GHz Wi-Fi networks
    - SELinux is in Permissive mode (this isn't a problem for most people, just mentioned it here as extra information)

    If you notice anything else, be sure to report it in this thread. While we're kind of busy, we usually read the thread and acknowledge the bug reports, even if I don't reply directly to them.

    Nougat build is up. No, I have not died, and neither has the Galaxy Nexus.

    Decided to take an extra couple days to get this build stable rather than rushing out something that boots and does nothing else, sorry for the delay. :)
    I can't verify the full functionality of the RIL since I don't have a SIM in my GNex these days, so let me know if there's any issues with that.
    Everything else should be working well though.

    No idea what to do for GApps at this time. I haven't tried them yet.

    As usual this was a team effort. @Ziyan helped, and @Hashcode (who I thought had died) helped as well.

    GApps
    If you want to install GApps, we recommend Open GApps Nano or BaNkS GApps.

    An important note: as this is a pure AOSP ROM, installing GApps tends to be problematic: in order to try to avoid installation issues, be sure to install GApps immediately after installing the ROM, before booting the system for the first time. After the initial bootup finished, be sure to go into Settings -> Apps, and grant every permission to every Google application - most importantly, Google Play services.
    In the case of an upgrade, be sure to re-install the GApps package, as upgrading wipes /system. You shouldn't need to re-set the permissions afterwards.

    One more note. DO NOT set up your Google account until you grant all permissions, otherwise you will be stuck on the initial setup.

    Rooting
    You can flash either the latest SuperSU or OpenSource SuperUser to get rooted.

    A wild android-7.1.0_r1 appears!

    We'll need to rename this project to Unlegacy-Android now that our migration from OMAP4-AOSP is done... sorry I haven't been paying much attention to XDA here. Spent a good week just getting video recording working on N, plus other things just in life of course.

    I can't attest to how well the RIL works, toro(plus) likely needs something fixed for mobile data still. maguro is probably fine.
    Other than that everything is working as far as I can tell.

    Source code is (kind of) available on GitHub. Right now there's no 7.1 branches up, but cherry-picking in our 7.0 branch commits and setting selinux to permissive should get you an identical build (minus a camera HAL fix specific to 7.1 which will be pushed tomorrow, I'm going to sleep)

    Edit: Fixed broken GitHub link.

    New build up:
    - fixed battery saving location mode (cellular network and wifi location)
    - fixed DRM services
    - fixed Wi-Fi Display (screen casting)

    Enjoy! :)
