Had a running 15.1 on my X522 and wanted to install the latest 17.1 version (20211011). Adb used to work when the phone was booted normally and I switched mode to transfer files.
So I flashed twrp recovery via fastboot, wiped everything and switched to recovery to sideload the zip, but now no adb device is detected. I already tried "enable adb", used other usb port and updated the driver (although I already had a working connection before).
How would I flash lineageos (I've got no sd card to copy the zip)?
