It is funny since it has been a full year, but I thought I would post an update. My Librem 5 USA works again!
I took it to a local phone repair shop back in May and after working with the guy for a couple of months, sending him documentation and so forth, we managed to get the phone to boot. It started booting once he opened up the phone to attach a USB cable. We don’t really know what was wrong.
I had Purism send me a new mid frame kit to replace the broken parts in the body, and now the phone looks like new.
However the phone’s days as my mobile phone are over. I will keep it safely at home and only use it for testing software to extend its life.
Good thing I have it working too as I see Muscle Buddy’s fast nav buttons are too touchy on the Librem 5’s touchscreen. Now that I know that is happening I can fix that for the beta 3 release.
