The spi message is fine. Fastboot getvar all for me pls?Here is what I did and noticed along the way. I reflashed the phone to the latest Android 11. Rebooted after install and there was no 'Factory' message anywhere (I was probably imagining that I had seen it at this point previously). So the phone was working ok (and I have confirmed that the cellular works at this point as well).
Then I started the install of LineageOS 18.1 (Dec 18 version). A couple things I noticed during the process. Firstly, when I got to the step of rebooting to recovery, the 'Factory' message did appear momentarily as it was rebooting into recovery. The second thing I noticed was that when I executed the Format Data I did see a message on the phone that I'm not sure I have seen before - "E: can't send spi message: try again". The following line was "Data Wipe complete". After doing the adb sideload of the zip file I rebooted and of course the "Factory' message showed up again momentarily during the reboot.
Any further thoughts on what it might be?
Eh, slot is less likely than some insure fastboot config lol but maybe!
