Hi all, I decided to flash Oxygen OS to see what it's like and to hopefully get some Google apps working that would not on Hydrogen OS (Contactless Pay). 5G also does not work for me in Australia on either firmware.
Oxygen OS is better imo but obviously as mentioned above, OTA updates are not possible without bootloop. I was able to update with local file option however, by downloading the firmware update file from OP website.
Swapping between the two firmwares is quite simple using MSM tool and OnePlus Switch App to backup apps etc.
I also found the following link for installing Cyberpunk theme options for those on OOS and can't live without the CP2077 goodies.
All aboard the hype train
