No.
For the OnePlus 6, Android 8 is pretty much dead. Because there are no good reasons (for devs and most users) to stay on 8.

You could try XenonHD 8.1 though, it's a bit more polished version of LOS in my experience and it still gets monthly updates

It's the only 8.1 Rom I know which is left. And it's pretty good in my experience. But I don't know how long there will be builds of this rom.
Why don't you want to use Android 9, if I may ask?

thanks so much!

first, there is no Xposed. i don't want to trade freedom for... whatever Pie brings, colored mirrors?

second, i hate google's upgrade treadmil. there is absolutely no reason to follow google. android 6 is still quite ok. all the reversing and hacking tools are struggling to keep up with google in exchange of nothing. google's android is increasingly an advertising and monetizing medium for google. i DONT want their new software at all. what i want is dependable tools that safeguard freedom (reversing tools), of which none are produced by google, and that are being left to rot because of needless changes google continuously introduces into the platform. i'm updating my tools now (eg dexpatcher) for recent androids after a number of years left to rot. dex2jar needed to analyze dalvik code is abandonware since android 6. people are using my fork which i updated for android 7 and 8 and might work some with 9. no xposed. everything is a mess.

the world needs a total fork from google with enough users to matter to developers. so that companies stop using google's IDE which ties them to googlephones.

the only good thing is, at least we have microg. which btw was abandonware till a couple of months ago.

i'll try your suggested rom.

unfortunately i lent my OP6 (wasn't using it) and it was upgraded to android 9. now i got the 9 firmware and the old 8.1 builds don't boot. i hope your suggestion was updated to work with both bootloaders. otherwise i'd need to downgrade firmware and i don't even know if that's possible. it certainly is dangerous.

i've asked:
https://forum.xda-developers.com/showpost.php?p=79409989&postcount=93

thanks again!
btw, if anyone knows how to downgrade from pie to oreo without using qualcomm's download mode, please post a link.

The safest way is to use the msn download tool, I think. So both slots get directly flashed
https://forum.xda-developers.com/oneplus-6/how-to/tool-msmdownloadtool-v4-0-international-t3798892

But you could also try to simply flash the 5.1.11 OOS zip in TWRP. But care, you have to wipe your whole internal storage.
So flash 5.1.11 + twrp, reboot twrp. Your storage will be encrypted.
Format internal storage
Flash 5.1.11 + twrp again.
Then it should be fine. (I think I did it this way once... but no guarantee given :D)

If not, you could use this: (do not use this to directly downgrade. Will lead to crashdump)
https://forum.xda-developers.com/oneplus-6/how-to/rom-stock-fastboot-roms-oneplus-6-t3796665/

I totally understand your reasons to stay on Android 8. I'm with you. Especially the Xposed part. Just for your information, there is a kind of Xposed fork which works on Android 9.
It's called EdXposed. If you want you could have a look at it. XPrivacyLua works perfectly fine with it.

thanks so much. i think i can use fastboot to downgrade (i wouldn't use twrp, too little control), but i rather go the official way cause i i don't know exactly which partitions to flash (and nobody seems to know for certain). i'm sure i'd get it to work, but would i be "stock"? don't know...

so i'll find a windoze box and go qcomm dl... crap! :((

ive been following edxposed for a while now. (i publish my own hacking tools so i need to see whats out there.) totally contrary to what it is posted on XDA articles, it is NOT closed source and it is NOT a port: it is a clean rewrite using various independent hooking components; very interesting.

however, it doesn't hook resources, so a lot of modules fail. btw i imagine xposed doesn't "hook resources": if i were to write xposed, i'd probably use the xposed code hooking mechanism to hook the system APIs that provide access to resources, and do the "resource hooking" there. if this is true, porting the resource hooking of xposed to edxposed (instead of a clean rewrite) seems easy as pie, so i don't know why devs haven't done it yet. but IMHO, edxposed is the future. it's not a one-man monolithic project, it uses several open independent libraries, so it is easier to maintain and less prone to the "bus factor".

    LineageOS is a free, community built, aftermarket firmware distribution of Android 8.1 (Oreo), 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 :
    • Download the latest build and gapps
    • Boot to recovery
    • Flash the latest build
    • Boot to recovery again
    • Flash gapps
    • Reboot
    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 /sys/fs/pstore/console-ramoops and /sys/fs/pstore/dmesg-ramoops-0. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
    • If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log
    Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues. Any bug not reported in the bug report format below may be ignored.

    Adds DT2W support and makes the slider behaves like stock

    Do you like the feedback when the slider changes? There is a /small/ vibration every time but I don't really like it
    Give it a try and tell me if you want it or not
