Hello,
good news: I finally installed UT on my XperiaX device! So happy.
Thank you for your advices. I did clear the cache actually.
Nevertheless, two points:
- the blue light never appeared on the device... (white, green and red are working so is it possible that the blue is not?)
- at the very end, after the installer's success panel explaining the "the installation process from the computer is done" I got an error message that I unfortunately did not manage to report (shame...)
But after switching on the device, both the "your devices is unlocked" and "Sony" logo appeared then UT starts!
IDK if those above points are problematics for the future but for the time being...Yeah!
I will test that device in the following days as a daily phone. (now, that looks better compare to my Nexus 4 16.04.
Thank you again
Best,
