Flashed
aicp_pro1_s-17.1-WEEKLY-20221005.zip on security update 2022-03-05
Still initial boot-loop after flash, And still completely confused!
Despite the outer file signals aicp-S and 17.1, the inner version is aicp 16.1 and tells it is Android 11??? So time to give up on AICP on Pro1 I guess!!!
...when I find the time this test-device will likely get Sailfish again...
The lot of mails MIGHT be the problem... For all we know on their help-desk system, sending a new mail, joins the new and the old mail, so they can be handled together, BUT at the bottom of the queue.
And don't ask me on the why it is this way. But at some point they told us that is how it works.
