If I want to return to stock OnePlus 5 ROM. Latest being 10.01.
Then flash latest recovery ROM which is 8.1.
And then lock bootloader is that the best way?
That's what I did and it works but is there not a Android 10 recovery img
Welcome! As OnePlus doesn't always provide direct download links for all of the OxygenOS full zips & incremental OTA zips, we have taken the initiative of mirroring them on AndroidFileHost and consolidating all the links in one place, so that they're easy to find.
Note: This is NOT a support thread for issues you may have with OxygenOS. If you need help installing or updating, feel free to ask here. If you have any other issues, please ask in the appropriate thread.
There are two types of zips for each OxygenOS release:
Signed Full Flashable Zips (>1GB)
These are recovery-flashable zips of the full ROM that won't overwrite your data partition. Can be flashed via stock or custom recovery (TWRP).
Incremental OTA Update Zips (<1GB)
These are also recovery-flashable zips that update your ROM to the newer version, but are a lot smaller in size. Can be flashed via stock or custom recovery (TWRP) but will only work on non-rooted OOS, with no modifications to system files.
You can find AndroidFileHost mirrors of all OxygenOS releases below:
