Does this ROM support USB ethernet adapters? I tried with a Cable Matters one, connected with a USB OTG cable but it didn't seem to work. The adapter lit up and seemed to establish a connection based on the lights, but it doesn't seem that Android got the message that an adapter is connected.

What version of USB MIDI driver is used in the firmware?

I'm trying to connect a synthesizer via USB-OTG, but MODALapp does not see the device, although there is MIDI support in Android 6. More information here.

At the same time, G-Stomper app detects MIDI devices, but according to the manual below, it looks like the classic Android 5.x based USB MIDI driver.
More information here.

Dear @Rortiz2, if the firmware uses an old version of USB MIDI driver, could you please implement a new version of the driver in next updates so that USB MIDI devices work properly? Thanks in advance.

I'll take a look

Quick follow-up question about SDCardFS: is there any particular reason why it was disabled in the first place?

Dear @Rortiz2 , I just installed Lineage15 on my douglas, it's perfect! Thank you for your rom. And I want to know can douglas support Lineage16 or 17? Is there any plan for building Lineage16 or 17 ROM? Thank you.
Yeah, douglas (and giza) can support anything at this point (even 18.1). I'll start with 17.1 as soon as I fix the last bugs here.

Why stick to an outdated version when you can upgrade to a lot newer version where you have much more configurations. Also, yes, you can optimize the apps and stuff so that it uses the same amount of memory in the end.

BTW: My problem is solved, thanks for any feedback!
You are right that we should focus on the newest version. I mentioned about A9, because this version seems compact to fit to tablets equipped only with 1.5G Ram. If A10 or later runs well on douglas, absolutely no need to pay attention to A9. Another reason is up to A9, we can build Rom with 8G Ram PC. Ofc, this is pretty personal reason, no need to have further consideration.
Let us enjoy new version of Android. Thank you @Rortiz2 for your endless effort.

Oh god, RAM is not my only problem. I'm building with a 2011 PC with a 2nd Gen I7 + 16GB DDR3 RAM. Feels good to be poor.

I'm also a dev, I just not really into android development, but I do have a PC that should work well for compiling the code.
If I can help with the development just hit me up, or even just building the roms for testing.
I have been looking at your github but no luck at actually figuring out how would I build the rom.

    LineageOS is a free, community built, aftermarket firmware distribution of Android 8.1, which is designed to increase performance and reliability over stock Android for your device.

    LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

    All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.
    Instructions:
    • Reboot to recovery mode
    • Wipe data, system (/system_root) and cache
    • Flash the ROM and the Gapps
    • Reboot and enjoy!
    Downloads:
    Reporting Bugs:
    • DO NOT Report bugs if you're running a custom kernel or you installed Xposed
    • Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
    • If it is a random reboot, grab /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)

    • Deep sleep (Doze)
    • Hardware decoding (OMX)
    • Camera (both photos/videos) isn't working on giza
    • Can't connect to hidden SSIDs

    • SELinux is in Permissive mode
    • The ROM only supports both douglas (Fire HD8 2017) and giza (Fire HD8 2016)
    How do i...

    Quick update; I'll probably release the latest version of 15.1 soon with some fixes and I'll continue working on 18.1 as I already started making the trees.​

    Good news to everyone. I partially fixed HW decoding (and this includes Video Recording) ;)

    EDIT: It fully works now

    • Fixed camera.
    • Fixed internal storage (OBB) issues.
    NOTE: Video recording isn't working at all, it crashes with the stock camera app but it works with some third-party apps (such as Telegram).
    NOTE: Let me know if obb issues are fully gone (I basically reverted the sdcardfs squash update). Try to clean flash the ROM as well before reporting if the bug it's still present.
