I’m trying to install SFOS on a Xperia 10 II ( XQ-AU52).
I’ve followed the instructions on How to install Sailfish X on Xperia™ 10 II on Linux - Jolla down to pt. 7.8.
However, after turning off my fully charged phone and waiting for the LED to turn off (pt. 7.7), I then press the Volum up button and insert the USB cable to my pc (running on Linux Mint 20.2 C), but nothing happens - no LED light at all.
I’ve tried with another cable to the USB-C ports of the pc (which only have such ports).
What can I do to get further?
Does the phone need to have a SIM-card inserted at this stage?
