If you want stability, Debian Stable is the way to go (Servers, mission critical tasks). Even Debian Sid works great on my Legion Go.I recommend Testing or Sid for desktops.
If you are using this as a server, I recommend Debian. If GRUB displayes, try text only/videosafe.If this image doesn't work, try x86 version.
Looks like it's supported. (No problem comrade.)To test the image without bricking, unlock your bootloader first and install DSU Sideloader to test the image. Once working, flash using regular fastboot.
Is using MicroSD cards a good way to store data so that you can destroy quickly incase an adversary is about to seize control of it?
Install Treble Info and use the appropriate image.Need help? Take a screenshot and I'll see what image is the best.
I'm pretty sure Verizon locks the bootloader on their phones. I had a S10e and I wasn't able to unlock it.It may be the same for you.
As far as I know, yes.I have a Xperia 1 VI (XQ-EC72) and bootloader is unlockable.For best results, don't go with the US/UK versions, go global.
