Do not unzip the file. Here's what i did. Downloaded the full rom zip on my computer. Open the archive with 7zip and just deleted the compatibility.zip and transferred it back to the phone. Booted in blu-twrp. Mounted all the partitions, wiped clean except internal and flashed the zip. No errors.

[MENTION=6143932]Funk Wizard[/MENTION] Is this true? If true I would rather stay being uncertified untill future updates that can fix the problem.

[OnePlus 5T  Guides, News, & Discussion] Seagorilla2:
For people having Trouble removing compatibiliteit.zip without corrupting the zip , try latest MiXplorer (search in xda). It worked for me doing a dirty flash from OB19 (wipe system and caches).

Had to reflash TWRP recovery from my old Windows Oneplus3 toolkit (USB debugging on in Pie) because it woudnt stick right after flashing Pie. After that i could install Magisk 18 without problems.

My Playstore (12.8.23) seems certified after data and cache wipe and a restart, but Safetynet wont pass cts-profile. Plus Adaway systemless host is not working. Will try somethings and report back.
[OnePlus 5T  Guides, News, & Discussion] shizla:

[OnePlus 5T  Guides, News, & Discussion] roytje2803:
To fix the certificate issue:

Q. My Play Store is showing "uncertified" after i downgraded to stable, how can i solve it?

A: Clear Google Play Services data and Play store data and Reboot. Let Play store update automatically and it should change the status to Certified.

Works the same for upgrading from beta to new beta

Successfully dirty flashed over Hydrogen Beta from December 1st. I removed compatibility.zip from OTA zip.

I used Blu-spark recovery.

My steps:

1.Flash OTA with removed compatibility.zip

2.Flash no-verity-v3 zip

3.Flash Magisk 17.1 as I forgot to check if I have 18 on board before flashing.

4.Reboot recovery just to check if it's still there.

5.Boot to system

Dirty flashed OxygenOS OB20 over Hydrogenos ob20.

Works great. ( Latest bluspark twrp, deleted compatibility zip)

Working fine :

Magisk 18

Safety Net, Gpay,Play Certified ( Maybe coz of Magisk Module)

Google backup automatically works great which I lost in Hydrogen ( Including Calllogs, sms, app data)

Decryption using noverity

To get Digital wellbeing check here

Gestures and overall system is much fluid compared to Hydrogen ( No idea why)

No sound interface crash or any crashes which few have reported in forums.

Weather Location was weird in hydrogenos which is back to normal.

(Other observation)

No custom fingerprint gestures support (third party apps) (was available in Oreo)

Zero improvement in camera.

Overall Pie is sweet and Gestures is awesome! :)
