Many thanks for the guidance and the warnings. And noted that the updates may/will over write whatever I have installed.
I have 2 Nexus 5 phones. One has hardware issues but works as my Guinea Pig device for trying something new in uncharted waters for me.

Believe I read that the Oneplus installation for the 6T is recommended to be
with a device that is running Oxygen 9??? Please correct me if I am wrong.

Also, anyone successful in deleting Oxygen 10 and installing the 9 revision on the 6T to accommodate the installing of Touch??

Wish to add VPN app to Touch, but system reports file system is locked when I attempt to install.
Key strokes in Touch to open file system and gain access to enable loading VPN and Miracle cast apps please.

Greetings one and all.
Very new here so if I am in the wrong category/section/place, admin please advise, and please direct me on where I should be.

Flawlessly loaded Ubuntu Touch OTA-18 (20210708-27954) [16.04LTS - armhf (20210708) ] on my New (old) Nexus 5. (I also pushed Touch to my Nexus 7 tablet and it went smoothly as well).

I can enable casting on the Nexus 5 and plainly see my Roku stick and my LG TV. Both of these devices have been casted to by my Nexus 7 tablet so both units are working.

Read somewhere that using an external monitor was not supported by the Nexus 5 (that may have been a dated piece of information that may have been solved recently???) My bluetooth headphones work well with the phone, so bluetooth on the phone is functional.

Any advice or suggestions would be greatly appreciated......
