Unfortunately, I'm not really up to date with these mobile phone things.
I have now tried to get the Android 9 required by the UBpots installer on the phone, with what felt like 100 instructions. but nothing worked. I see my only option now is to leave the phone lying around until UBports supports the installation with Android 11.

Thanks for your time

UBports.exe does not recognize the smartphone in fastboot mode

then i have the error
``C:\adb>fastboot boot TWRP-3.6.2_11-OP6xT.img
downloading 'boot.img'...
OKAY [ 0.817s]
booting...
FAILED (remote: Failed to load/authenticate boot image: Load Error)
finished. total time: 0.835s

C:\adb>
I entered
fastboot flash boot_a twrp.img
using cmd and restarted the smartphone.
twrp was running.
I then loaded the last official One Plus 6 Android from the One Plus website and copied it from the pc to the smartphone using the file manager.
Then I installed the .zip file via twrp and I'm back to where I started.
i have android 11 and want ubuntu touch.
is it possible to get Ubuntu Touch as a .zip file? I didn't find anything at first only UBports Installer.

I've now played a bit with the key combinations and I'm back in fastboot mode. Yay. "cmd adb fastboot devices" shows me the device.

what can I do now ? Unfortunately, UBPorts does not recognize the device and I can press everything in fastboot mode, it always starts in fastboot mode

Hello, I tried to upgrade a One Plus 6 to Ubuntu Toch using UBport.exe. unfortunately something must have gone wrong. The smartphone is now in Qualcomm Crash Dump Mode. Do I still have options in this mode to make it accessible to UBport? In my opinion, there is no longer an operating system or something similar on the smartphone, only the crash dump mode without options

I hope you can help me here
