I have a similar issue on my Xperia X. My router has a seldom used name. If I leave it and I come back, it will automatically connect again. However the router / wifi network of my wife's parents has still the default name lets say "FritzboxXYZ". If I connect to it and leave the house the phone finds while I am going through the streets routers with this name and pouts a pop-up message on the screen that it found the router "FritzboxXYZ", however was not able to connect or and asks for the password, if I remember correctly. When I come back home, it detects my router immediately and if I go to my wife's parents house, the wifi router will not be detected anymore. However, if I restart the phone, it will immediately connect to the router "FritzboxXYZ".
Could it be the case, that you are using the routers default name or a frequently used name? Could you change the router / wifi networks name to a seldom used name? Does it work then?

Due to the black screen on Dekko 2 I switched on Xperia X lately from Dev to RC channel. Now the RC channel with latest update has also a blank screen.
Thus I switched to stable. This works fine as far as first tests indicated.

@alexjoverton

I am new to ubports.

Could you please provide more details how / where to get Dekko2 ReleaseCandidate.

As above with ubports-installer_0.8.4-beta_linux_x86_64.AppImage failed (latest version available) and I was unable to get the downloaded file SW_binaries_for_Xperia_AOSP_N_MR1_5.7_r1_v08_loire.zip / *.img accepted, I used ubports-installer_0.7.4-beta_linux_x86_64.AppImage, a previous version I still had on my computer and this worked.

After that I was able to reinstall with ubports-installer_0.8.4-beta_linux_x86_64.AppImage (latest version). This time it was not requested to manually download the image file. Installation worked.

Still there is the issue in ubports installer version 0.8.4 (ubports-installer_0.8.4-beta_linux_x86_64.AppImage) that installation of the image file failed before and why it is now working.

@phoenixlandpirat

No I did not. But now it worked. It found the Xperia X device itself. I guess I had the ubports installer opened twice. I found another window in the background.

But now I have another problem.

I had to download the SW_binaries_for_Xperia_AOSP_N_MR1_5.7_r1_v08_loire.zip from Sony manually. I have checked the sha256sum from the downloaded file against the checksum provided by Sony. It was the same.

I extracted the image file from the zip file and went on with the process.
Now I get the following error message:

I have tried it both. With the zip file and the image file. Both provide the above result. this was with ubports-installer_0.8.4-beta_linux_x86_64.AppImage

I made here a separate issue:

I had installed on my Xperia X Sailfish X OS and managed to install with ubports installer after some time to install ubports successfully (directly without reinstalling android before). This was quite difficult and I guess I had to activate the developer mode in sailfish os before.

Today in ubports a software update failed and therefore I tried to reinstall ubports with the ubports installer and I got the message.

Even if I had installed it some time ago with uborts installer.

I have installed on my Sony Xperia X Ubuntu touch. Today under software updates a new update version 609 appeared.
I downloaded it and installed it.

The install restarted the phone and the sony bootloader reported a recovery error. Thus the bootloader went back to the previous version from 21.01.21.

When I now come back to the software update menu, it still provides update version 609 as available, downloaded and ready for install.

If however I try to install it, it asks for "Restart & Installing" (german "Neustart & Installieren"), but nothing happens.

Now I have tried to install ubuntu touch with the ubports installer from scratch.
This failed with the above image, even if it worked successfully with a previous version of the bootloader before.
