New phone

[totilele]

The inactive SIM shouldn't cause any problems. Pulling the battery out might affect the modem, but probably didn't, and even if it did it's recoverable. Start with these sections of the wiki:

https://wiki.pine64.org/wiki/PinePhone#O...ng_systems

Please ask about any terminology you don't understand. Remember that the PinePhone and the PinePhone Pro are different devices with different boot orders and software requirements, so don't make the mistake of following instructions or downloading software for the wrong one as it won't work.
I'd suggest picking one of the more widely used distros like Mobian or Manjaro Phosh to start with. Their installation instructions should be better, although occasionally a change to software gets out before the matching change to the documentation.

Besides, have to mention that when I turn on my phone, it says PostmarketOS, so it means some OS is there.
