Yes, I was on 5.0.4 with unlocked bootloader, rooted with Magisk and encrypted. Followed this thread

https://xdaforums.com/oneplus-3t/how-to/guide-cope-9-0-3-5-0-8-firmware-barrier-t3941164

I installed Magisk 19.3 at the end. Also, just to be sure, I had flashed TWRP again after flashing modded firmware and rebooted into recovery once again.

Took me 10 minutes on first boot but all apps and data was intact, as well as encryption. Works as good as Oreo. However have a feeling that battery life is slightly reduced and not getting the correct battery statistics. Have installed Franco kernel also. Will allow the battery to completely drain once and then see how it goes.

Only issue I am facing is with Magisk. Device is rooted but getting Magisk error at times and it is closing. When I updated to 19.3, I saw a separate Magisk Manager apart from my old one and in the new one it said that Magisk was not installed. When I tried to install I got error "unsupported format". But as soon as I open old Magisk app, the new one disappears. Need to find a solution to that but everything is actually working well.

I don't see need to go back to Oreo as all apps and functions are working.New UI is nice and a change. I did not find any new features which were earlier not present. Maybe I did not see hard enough.
[OnePlus 3T Guides, News, & Discussion] brmbjn:
now are you try to dirfy to 9.0.4 ? success ?
[OnePlus 3T Guides, News, & Discussion] :
No.

The new modded fw is in work. See my last posting.

If you keep the 5.0.8 bootloader on 5.0.8 -> 9.0.3, you have to keep it from 9.0.3 to 9.0.4, too. See the metionedmthread for modded fw for details.

[OnePlus 3T Guides, News, & Discussion] jesrani:
Thank you so much for this. Can you also let me know how to solve the issue I am facing with Magisk. I had Magisk installed earlier and then I installed 19.3v from TWRP during the upgrade to 9.0.3. However, there was were 2 Magisk apps now seen. When I opened the new one, it said Magisk was not installed and when I tried to install, I got "unsupported image format" error. When I opened the old Magisk Manager, the new app icon disappeared. Root is working and I am able to hide root too for apps. But my old Magisk asks me if I want to install the new Magisk Manager v7.4 (I think). However when I do this again the above behavior happens. Can I uninstall Magisk and reinstall the new version? How to do this?
[OnePlus 3T Guides, News, & Discussion] :
Sorry, no clue at all. Flashing magisk after a dirty flash shouldn't be necessary, if it was installed previously. (strike: only true for custom roms, sorry.)

Have you tried uninstalling both apps manually, flash magisk uninstaller, wipe cache and dalvik, reboot to system, reboot to recovery and finally flashing magisk again?
[OnePlus 3T Guides, News, & Discussion] jesrani:

Is anybody on stock 9.0.4 able to check if they fixed the SELinux mode? On 9.0.3 (and earlier Pie beta and stable releases), SELinux was set to "Permissive" - causing SafetyNet to fail on stock devices.

SELinux mode can be checked with

adb shell getenforce

Expected mode is "Enforcing".

[OnePlus 3T Guides, News, & Discussion] :
See the lineageos thread for details. This happens, depending on the bootloader configuration. We havn't found a simple way to reset the bootloader configuration, yet. But a complecated way is available.
[OnePlus 3T Guides, News, & Discussion] MrBlackbriar:
I have a locked bootloader (and fully stock device), so I would not expect needing to mess with the boot.img. But thanks for the hint, I'll check out that thread to see if anything applies to my device.
[OnePlus 3T Guides, News, & Discussion] :
bootloader has nothing to do with the boot image!

You are right: unmodified bootloader config (I'm not speaking of bootloader state!!!) shouldn't have this issue and shouldn't change the boot command. Since yoir bootloader is changing the boot command...

[OnePlus 3T Guides, News, & Discussion] jesrani:
Upgraded from 9.0.3 to 9.0.4, thanks.

Seems more responsive, need to see battery life. Have not installed custom Kernel on 9.0.4.

Am facing issue with Magisk Manager 7.3. Hide is not working and some apps not working due to this. Had to revert back to 6.1 with Magisk 19.4 version and everything working.

Adaway was also not working even in systemless mode with latest Magisk Manager and is working now.

An app Kernel auditor is not detecting root and hence not working.

Otherwise all apps working. Happy with the update.
[OnePlus 3T Guides, News, & Discussion] MrBlackbriar:
Right, boot.img is the kernel - it's been too long since I was involved with custom ROMS, my bad.

I guess the complicated fix you mentioned is post 2670 by zezinho7. Looks possible, but I'd like to end up with a fully stock device again (and am shying away from performing another clean install). Thanks for pointing me to thread, I'll keep an eye on it in case somebody finds an easy solution (or this gets fixed by OnePlus).

[OnePlus 3T Guides, News, & Discussion] Axonis:
Clean installed 9.0.4, coming from NitrogenOS (I needed encryption). No problems with installation or encryption. So far no hardware issues nor software that I'm aware of.

Performance is solid, no stutters in basic usage. I will have to see about battery life, but it looks like solid update. If you're thinking of clean install, it's safe.

Also I'm using FK-r48.

Before just blindly flashing now, I strongly recommend reading this thread for different installation methods and requirements (ppsting #3) and all kinds of nasty issues that may occur.

what is the best way to remove system apps now? Like google keyboard, google videos, games, drive etc?
[OnePlus 3T Guides, News, & Discussion] BillGoss:
I use a Magisk module to do this so that I don't have to touch the system partition. The list of files removed is in install.sh starting at line 37. Change the list to suit and then zip up the files again.

Note, it's best to flash it in TWRP (Magisk Manager is picky about how you zip up a set of files).

Read up on the Magisk module documentation https://topjohnwu.github.io/Magisk/guides.html

Are first boots longer than 20 minutes expected after following the 3rd way (for switching from custom ROM)? Not sure if it hangs or does something useful (like encrypting... :D)
[OnePlus 3T Guides, News, & Discussion] Paschfire:
Imho 20mins sounds a little excessive, but yes. The first bootup of OOS 9.0.X can take longer than usual.
[OnePlus 3T Guides, News, & Discussion] panaut0lordv:
So... actually I kept it for a bit longer and I don't think there was any progress. So as much as I wanted to try that one I failed.

I even had Lineage OS 16 running for a few hours on that firmware so I could at least have Pie but felt... slow? and unrefined.

TWRP restored OmniROM 8.1, just upgraded firmware to 5.0.8. Maybe in autumn I'll retry a new build, as for now I got so frustrated :D (and I consider myself pretty proficient around the phones).

Both OP stock recovery and latest didn't manage to flash and then properly boot 9.0.4. Tried 5.0.8 as a baseline and it booted and even prompted 9.0.3 build as available, but install also failed.

note: I had UB at the start of the operation and I tried multiple variations with locked/unlocked + twrp/stock + fully wiped/after-5.0.8 data. I have A3003 variant of the device.

[OnePlus 3T Guides, News, & Discussion] Paschfire:
You must Root the device, or flash a custom kernel, before booting into the OS. Otherwise the stock recovery will be re-installed upon first boot.

It takes 30+ minutes for 9.0.4 initial boot after clean flash from custom rom. Anyone knows the possible reason of this problem?

[OnePlus 3T Guides, News, & Discussion] Paschfire:
Just so you know...

As long that you always flash Magisk (Root), or a custom kernel, or a patched boot.img(step #4) immediately after flashing OOS(step #3) and before booting into the OS for the first time after upgrading. Step #5 is completely unnecessary.
[OnePlus 3T Guides, News, & Discussion] mkumaraguru:

Wipe Dalvik, system, data and also format data partition. Flash OOS oreo and then Magisk or patched boot image.

thank you so much

do you know if and how to turn off the update warning?
[OnePlus 3T Guides, News, & Discussion] mkumaraguru:
Then flash Magisk to get root access and install titanium backup to freeze system update service. After that, if root is not required, flash Magisk uninstaller.

Then yes, you'll need to perform a factory-reset/full format of internal storage afterwards. Or return the device to complete stock, then relock the bootloader and proceed with the update.

You have a few options...
