Yes. It wasn't possible with the release zip for stable 188.8.131.52 because the build date was before the build date for OB4. But with the 184.108.40.206 stable version it is possible again because build is more recent.So, just to confirm... You install stable 11 (EU) over beta 4 (Global) ?
You didn't use any other rom to go back to 10 and then to install stable 11....
I tried that, too On beta 4, after unlocking and installing magisk, the device not only remained on L3 but became uncertified in Google Play. It looks like this might be a specific problem to me: I have an HD1907 that was converted by OnePlus to use the general North American firmware of HD1905--these were sold by B&H on closeout at the end of last year. See here:I haven't relock my bootloader but have test global stable oos 11 and ob4 and widevine is working fine even on the different custom roms I have tested it still active. Remember to root and hide magisk for it to activate in case you don't have it yet, that simple step might help you.
This. I am in exactly the same position. Can 't flash official over it since the build date is older than beta4.Does anyone know when beta 5 is coming out?
It works fine but the camera is starting to irritate me.
I can install the stable version but then everything goes back to factory settings.
I have done this enough lately, so I'd rather not do it now.
