"adb devices" doesn't return anything for Xiaomi Redmi 7a running Ubuntu Touch

[TheDudeAbides]

Hi guys, as the title says I have UT on Redmi 7a, running fine. I am trying to get Anbox running on it, as according to post #8 on this page: https://forum.xda-developers.com/t/guide-gsi-ubports-how-to-flash-ubuntu-touch-gsi-in-redmi-note-7-7s.4131725/
The problem is that when I run adb devices (either on my UT phone or on my host computer running Ubuntu 20.04), I don't get anything listed.

My host can see the phone in fastboot, but not in normal boot.

I have tried everything suggested here: https://askubuntu.com/questions/863587/adb-device-list-doesnt-show-phone
I am using the manufacturer usb cable that came with the phone,

the phone is in debugging mode,

~/.android/adb_usb.ini has the vendor id "0x0fce" (Sony) in it,
(I believe that Onclite was built for Sony, that is why it sees it as a Sony with lsusb, or maybe the vendor files flashed are more likely the culprit for this)

/etc/udev/rules.d/51-android.rules already had the line
SUBSYSTEM=="usb", ATTR{idVendor}=="0fce", MODE="0666", GROUP="plugdev" in it.

I did everything described in the link above, running out of ideas.

I have also tried installing phablet-tools but to no avail, see this:

Anything else I can try? or any other way of installing Anbox for this phone? Thanks.

My bet is on trying other cables.
It's often a bad data connection that prevent ADB to find the phone.

@applee Hi, the same (manufacturer & brand new) cable sees the phone in fastboot mode
