So my oneplus6t arrived.
Was able to unlock it via the ubports installer.... Only for the installer to fail midway and brick my phone.
I'm at the quallcomm crash screen now.
If I try to install ubuntu I get the attached error 
Is this something UBports installer can resolve or shall I troubleshoot the qualcomm crash before attempting again?

Here's the crash report - this is after qualcomm crash and going into fastboot and trying to install either postmarketos or UBtouch
