Running the beta build so far it's looking amazing! Once I know that the beta has been finally released to the UK I'll flash back to stock and then request an invite to the beta which then should be the second batch.
I am on ee , my phone is G960FXXU2BRH4 , where do I find the update to change the beta update.
Terry be sure to install an BTU firmware version which you can find on Sammobile, downloads speeds are slow with free account, once you've got that, install it, check latest security patch, check brj6 as build number not baseband..
Then do the update.zip, there are links in 3 separate threads one for s9 & 1 for s9 +, if you can't find then private message me..
Tutorial I made is a few pages back also you'll find it. Should help you an some others out
If you guys are stuggling downloading at 3 kpbs from Sammobile there is a much better way.
I used SamFirm V0.3.6
Just type in your Model and Region and so for my S9 Plus it was G965F and for the UK its BTU for the region.
It will then download the latest firmware that the beta can be side loaded to.
FYI. Because one UI is beta it will make your play account unverified so if you use google pay etc set it up before you sideload the beta.
