Happy new year! Just clean flashed the new build and microg still claims there is no spoofing support. I'm using the magisk module (microg installer revived), if that matters.

Good morning and a happy new year to all of you! Thank you very much for the new ROM, I tried the Giza one right now, but unfortunately, the camera is not working (I tried with OpenCamera). And for MicroG: no signature spoofing capabilities right now. Appreciate your effort!!

Not sure what's wrong with MicroG then. The patch is there (and applied, I double checked it). Can't do anything else, sorry. As for giza camera, try to grab boot logs, they should be different now.

Thank you Rortiz2 for your kind offer! I appended a logcat when trying OpenCamera that I compressed to save some space (hopefully this is useful, since I haven't used logcat before). I personally am very happy with your ROM, as a working camera on that tablet is not important for me. Btw. MicroG reports missing spoofing capability on douglas with its self test just as well, but let's see what other users of your ROM report back ...

Well, I'm not sure it's microG, just used smali patcher to generate the magisk module and after installing it, spoofing works... so maybe the patch doesn't apply on 15.1 the way it should... Thanks for double-checking it was in!

will the microG patch mess with CTS/SafetyNet ?
 
Happy new year everyone. I have been using LineageOS 15 on my Douglas for a few months now. I've been having an issue with mesh WiFi for some time now. Instead of seamless switching as I move around the house, I get these disconnects, and reconnects. Has anyone else noticed this? There are no WiFi issues as long as I stay in one room.

Not a big problem in general, but causes some video streaming apps to stop buffering. I figure that is probably an app issue, where they aren't handling abrupt disconnects/reconnects properly. But I do not see this behaviour (WiFi disconnect/reconnect) with my other devices.

I am on the latest update at the moment, January 2022. I have a set of three Tp-Link Decos around the house.

Interesting, thanks for the report. Mind if I send you a zip in PM to see if the problem gets fixed?

Thanks for the log, but unfortunately it's kinda useless since I can't see how does camera init. Could you grab instead a log while you power on the tablet (Amazon Logo -> LineageOS bootanimation -> Home Screen)?

For me it also happens with one access point - I randomly see the Wi-Fi icon going hollow - not connected to any AP. That is with me not moving... I think there were reports about that before?

Hello everyone, new forum user here. Recently installed this build of Lineage on my Douglas, and just grabbed the latest update. All the major features are working fine. Only problem I have is the SD-card inaccessibility bug (device sees the SD card is inserted, but can't read any of the files on it). I'd love to see a patch for that, if possible. Otherwise, it's working much better than FireOS ever did. :)

    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.​

    Thank you @Rortiz2 for still taking the time to release OS for this old little tablet. It is actually all I need for airplane trips for work and, well, I'm a little too cheap to buy something else for using a few times a year.

    At this point, I'm good with TWRP and have your latest Lineage 15.1 installed. The only thing holding me back from not reinstalling FireOS is apparently SafetyNet - can't install Disney+ or Netflix for media. Any suggestions on getting around SN?

    And if you need a tester, I'll happily install 18.1 as soon as you release.

    Hey, not sure what happened, but I turned my Douglas on after a few days and it was stuck in a boot loop or something. It got stuck on the LineageOS boot animation for a while and then rebooted to TWRP automatically. This happened every time.

    1. I tried to clear cache, but it said
    Code:
    Failed to mount '/cache' (No such device)
    2. Then i tried re-flash this rom zip, that I already had on the internal storage and it said "Failed to mount (No such device)" for `/cache`, `/system` and `/data`.

    Now I seem to have lost everything that was on the internal storage, and it cannot mount anything. It won't connect to my computer either. It says "No media storage found. Make sure device is unlocked and MTP is enabled." It seems like the data partition does not have any file system format. And am unable to create one either. It says
    Code:
    failed to mount and unable to recreate `/data/media`

    I would try to flash the old Fire OS image, but can't seem to mount the internal storage on to my Linux pc. Any ideas?

    Edit: I also tried the repair file system, but it gives me the same "Failed to mount" error. And I found an old TWRP backup that i've been trying to copy onto the tablet using adb, but it keeps rebooting after like 20%. Maybe the internal storage is dead?

    Edit2: Okay, so I successfully copied the backup to the mounted SD card. But it during restore using twrp, it says This /data backup was made with ext4, so i need to change it back to ext4 to ensure it boots. But it won't let me change file system using twrp

    Code:
    Formatting Data using mke2fs
    Done.
    Failed to mount '/data' (No such device)
    Unable to recreate /data/media folder
    Updating partition details...
    Failed to mount '/system' (No such device)
    Failed to mount '/cache' (No such device)
    Failed to mount '/data' (No such device)
    ...done
    Run the following commands with ADB on TWRP and PM me the results.
    Code:
    adb shell cat /sys/class/block/mmcblk0/device/cid
    adb shell cat /sys/class/block/mmcblk0/device/csd
    adb shell mount -t debugfs none /sys/kernel/debug
    adb shell cat /sys/kernel/debug/mmc0/mmc0:0001/ext_csd

    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)
    Known issues:
    • Deep sleep (Doze)
    • Hardware decoding (OMX)
    • Camera (both photos/videos) isn't working on giza
    • Can't connect to hidden SSIDs
    Notes:
    • SELinux is in Permissive mode
    • The ROM only supports both douglas (Fire HD8 2017) and giza (Fire HD8 2016)
    How do i...
    • Unlock and install TWRP?
      • Follow the instructions of the unlock thread (douglas | giza)
    • Go back to the original/stock ROM?

    • 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.
