ADB running at boot never worked, though running whether on normal operation or on recovery works flawlessly.

As the phones were needed, I had to do factory reset them, which worked out. But, that doesn’t prevent me to keep trying to get ADB working at boot, which to be honest I never tried before. It seems important to get it work, so I can get and share the logs that matter. As you mentioned, linux info and logs from recovery are useless, :( But now there’s no rush, since I unfortunately did a factory reset.

I think I got another moto same model, not in use, which has broken mobility data (it doesn’t get internet while on mobile), and I think I can keep trying from it, but without upgrading with this dangerous version, since I want to detect with it if the coming upgrade is as dangerous (lesson learned for me is to try with that broken phone before attempting on the ones in use). This way I don’t take the phones that are already in use. So again, I’ll keep trying the , but now not that pressured.

It’s weird to me that I could use ADB on recovery, with no issue, even to transfer files, which to me it means there were no authorization issues then, and it never worked on boot. As mentioned, I’ll modify the pseudo-broken phone and keep trying the ADB on boot with it…
