Hi,
This is the first time trying to install UBPorts on my old Oneplus 3T.
It had the stock OxygenOS 9 and not rooted.
I first tried the Windows installer. That seems to be completely broken as it says it can't talk to UBPort servers.
I then moved to linux and tried both Snap, deb and appimage and get further but get the same result.
When it says its pushing the files to my phone. On the phone itself I have a yellow text Android Recovery screen.
But I get the following message just over half way through. I've tried 2 USB cables I'm almost certain that it is not loosing connection due to a bad cable or port.

Can any please help?
What log files do i need to be looking for to get more info?

@thilov Thank you. That did the trick.
Needs a step in the installer to say to install TWRP then as I didn't know about that.
Phone is now setup and working good so far.
