今天重新编译了一个userdebug版本，目前用起来感觉还不错

I will flash it when a stock version gapps 8.0 is available.
Edit:
Oh I have found it: https://androidfilehost.com/?fid=673368273298983999
Now I can experience a stock-like Nexus ROM.

Dirty flashed over Noobuilds and the only issues are that Bluetooth crashes and it encrypted my device, but can live with that, especially given that I dirty flashed a completely different version of android

Rooted with Magisk 14.

My fault.I forgot to modify fstab file:crying:
But I used SuperSU for root and it seems to prevent device being encrypted.So I didn't find that

Well it works, but I've gone back to my original rom only I'm not sold as to whether or not this is a genuine Android 8 rom as I noticed it making mention of Android 7.1.1 when installing. Also surprised that it would install over the top of a 7.1.2 AOSP based rom with no issues as such.

I could be wrong of course!!

It's just a build fingerprint in lineage.mk

and doesn't make any sense for Google only released Android 7.1.1 for Nexus 9.
And LOS15 is in the early stage so there won't be much difference between AOSP and LOS I think

The first builds of unofficial Lineage still had CyanogenMod text in some places

Thanks for your work. Can you make a new version that doesn't encrypt the tablet please, when you have free time?

Can you post the file /fstab.flounder ?

If the problem is the option "forceencrypt" that needs to be replaced with "encryptable" in fstab files it's very easy to do. For instance with a zip that I made some time ago that disable forceencryption and dm_verity.

That's it.I just replace forceencrypt with encryptable in fstab
And I'll start a compile if everything goes well after I finish my exam tomorrow.
Thanks for your post again

You are saying that installing the file posted by you, will not let encrypt the tablet. Right? This file will not alter other files (like boot.img) which is my concern? Thanks

Typically, it will. dm-verity/verified boot is a kernel feature, hence completely related to boot.img. :good:
The file will probably patch your current boot and disable forced-encryption.

The zip will extract boot.img, replace fstab and will repack again. Check the script boot/editramdisk.sh, as you can see it replace the word forceencrypt to encryptable. All the scripts were took of FIRE-ICE or ElementalX I believe, I only removed all the parts related to zImage...

I can't flash now Lineage to test this zip, so if you can't wait, make a backup and try. All should be fine, but I don't know if anything changed in boot.img parameters (like pagesize, ramdisk_offset, tags_offset, etc...)

So far this ROM is awesome! The only bugs I've found yet are face unlock and NFC not working. Anyone who doesn't care about those issues can use this ROM as a daily driver. I'd never dreamed of such a stable unofficial 8.0 ROM until I found this one, since speaking of third-party ROMs Tegra sucks (e.g. Two gens of Nexus 7, the 2012 version with Tegra received 6.0 port while the 2013 version with Snapdragon received 7.0 port) and Google abandoned updating Nexus 9. Great thanks to the OP!
