There is a few ways to apply update.zip, this is the easiest IMO..
You can do it via ADB but that is something to difficult for some & requires a laptop with more tech knowledge. sorry..
You will need:
Samsung S9 or S9+
1x (Min) 2GB SD-CARD
Little Technical Knowhow
Lets get into how i done it..:
1. Download the update.zip on your device..(DO NOT EXTRACT)
2. Move or copy to an SD-CARD inside your device..
3. Turn phone off
4. Hold power + bixby + volumeup, only let go of power when logo apears, KEEP holding other 2 buttons..
5. Wait till you see recovery mode
6. Use volume keys to move up and down.. then select apply update from SD-CARD
7. It will then ask you to select the folder/file
8. Press power to select update.zip you downloaded earlier that is now on the SD-CARD
9. Wait for it to verify & let it restart itself..
10. Be patient as above step can take upto 30minutes
You will not lose data, all apps and files will stay on your device, but as always backup just incase..!!
Installed on XXU for myself, worked like a charm for me, no issues at all..
Samsung Members APK LATEST VERSION
This is to just update from a BRJ6 firmware To One UI...
Check your version in settings>software information...
If you have a BRJ3 firmware i can't promise you that this will work.
Check to see if you can update to the latest November Security Patch, im sure this gets you BRJ6..
This is just an update.zip (ALL SAFE)
I do not accept resposibilty from what you do to your device, you are held accountable for anything that may happpen..
Any Problems report back here, i will reply when i can
I have the unlocked so plus in uk. I was told on messenger today they don't know yet about the android pie beta release. Told me to keep an eye out for it soon.
If I install this on my girls phone will it update to further beta versions? Anybody knows? How this gonna work with the whole registration process when beta program will go online? Will it let to register and get further updates?
Is does not void warranty as it's all done via the stock ROM .. nothing will void as its signed by Samsung &, it's from Samsung..
Knox warranty stays intact, healthworking both are fine
