Oppo A52/A72/A92 Android 11 update via VPN - OPPO A72 Guides, News, & Discussion

Hi,
I managed to get the Android 11 update with a bit of stuffing around and thought I would share for everyone else, I did this on a unlocked Australian variant bought from Optus, you're mileage may vary.
This will activate dual sim mode on the phone with a single IMEI, I left my location set to Europe so it is upto you if you follow the last step to remove Dual Sim Mode.
You will need to backup anything you don't wish to lose as a full factory reset is required.
I did some digging and this will work with the same rom on A52, A72 and A92.
Could I get a moderator to cross post this to the other device forums please?
