I want to make sure you don’t miss @moon3 's comment here: How knowledgeable do I need to be to operate the Librem 5 for basic needs? - #4 by Moon3 .
I made a similar comment in that thread. It was considered by the moderator to be off topic and, so was, made a thread itself. Here’s a link to that discussion. The travails of updating and reflashing
This thread started in November 2023. I’ll point to this as what an intelligent person with no/limited Linux/Unix experience (Linux newbie) should expect in regard to dealing with a Librem 5. And this is with people who seem to be falling over themselves to be helpful.
That thread moon3 pointed to was started in November 2023 because her phone was no longer working well and it need to be reflashed. She only recently (this week) finally flashed the phone. Honestly, I would ask her opinion.
