I don’t know, but it seems unlikely to me.
Yes, unlocking the bootloader resets the installed OS (incl. settings to default) and deletes all the user data, but a successful facory reset should then also allow the phone to boot again, which it cannot.
And since this was so clearly unsuccessful, I wouldn’t even want to speculate how far into the actual OS it got.
Yes, it shows up when I run fastboot devices.
That’s why I thought I might be able to reflash…
I’m not sure I understand what you mean. Do you mean it would fit if it didn’t show up?
I would have thought the installation shell script should abort a bit earlier, in such a case, but I dind’t look into it, TBH.
