Problem installing Ubuntu Touch on Sony Xperia x Performance

fips

Stuck in Loop White Screen with 'SONY'-Logo , warning screen 'Your device was unlocked and cant betrusted'

I tried to install Ubuntu Touch on my Sony Xperia x Performance dora_dsds. It hab stock android 8.
I activated developer options and usb debugging, unlocked the oem bootloader.
UBports Installer started but stalled with preparing image.
The device entered a loop with White Screen with 'SONY'-Logo and warning screen 'Your device was unlocked and cant betrusted' and the UBports installer lost the connection to the device.
I tried multiple times in fastboot mode to install (with the installer), but h the behavior was always as above.

What am I doing wrong ?
Is there an alternative way to flash? I found:
https://forum.xda-developers.com/xperia-x-performance/development/testing-ubuntu-touch-xperia-x-t3960133

but I really didnt find where to get rootfs.img and so on ....

I would really apriciate any help !

@Lakotaubp Thanks, I will check it out soon !

It was really good advice, i made up to the installer saying "Sucess!" but the phone still stalls in the white screen with 'SONY' - logo !

maybe it is because i have a DUAL-SIM device dora-dsds (NOT dora ???? )
Its a little bit frustrating ....... but i really want ubuntu touch !

Best regarts,

@fips
When just installed first uTouch boot can be veeeeeeeeery long, more than five minutes on the device "splash screen".

@Keneda Thanks for the tips, but my device is now stalled in splash screen fpr over 1 hour .... im still waiting and hoping
Seriuos: does anybody happen to know if the dora Ubuntu will work on a dora_dsds (dualsim xperia x performance) ?

@fips After about 3 hours in splash screen I finally forced shutdown. I don´t think it would have booted later on.....
I would get a dora (instead of dora_dsds) if i where sure that thats the problem.

Maybe it was naive of me to just flach the ub touch to a Xperia dualsim (Code dora_dsds).....

So does anybody know if it is a problem installing ubuntu touch (for dora) on a dora_dsds ?

I have single SIM xpedia x performance and exactly the same issue - so i dont think this is "dual" related...
