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.
[ROM][UNOFFICIAL][8.1] LineageOS 15.1 for Amazon Fire HD8 7/6th gen (douglas/giza)
- Thread starter Rortiz2
- Start date
@Rortiz2 Is there any hope that MIDI will be fixed in this version? Or do I need to buy a newer tablet?

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
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
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

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_csdHi @Rortiz2, like others have been using this ROM and everything works great (except for rear camera which for me is very dark/unusable but front camera works fine). Really appreciate the hard work you have put into keeping this tablet relevant!
One question for you, is there any chance that you will have a patch for SafetyNet like you did in 12.1?
One question for you, is there any chance that you will have a patch for SafetyNet like you did in 12.1?
From what I recall the rear camera worked fine in 12.1 and also in FireOS for me, have not been able to use it in 15.1 though from the beginning.
I'm sure @Rortiz2 is busy with 18.1, was hoping maybe the SafetyNet fix was similar to whatever was done in the patch for 12.1.
Yes, the camera exposure is completely broken. As a workaround, download a QR reader app from the Play Store and use it. After that, the camera exposure should be back to normal.
To be fair, I never cared about SafetyNet, and in fact, not even LOS does. I guess you can use some of these Magisk modules to workaround it.
Here's the problem with that: the fact that
(A) the exposure is broken, and
(B) the camera image is rather grainy to begin with
means I can't actually scan a code. And that workaround doesn't seem to do anything if a code isn't scanned.
You don't need to scan a code, opening the app should be enough to adjust the exposure.

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.Instructions:
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.
- Reboot to recovery mode
- Wipe data, system (/system_root) and cache
- Flash the ROM and the Gapps
- Reboot and enjoy!
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)
- Unlock and install TWRP?
- Go back to the original/stock ROM?
