I’ve been trying all day to boot my Librem 5 from an SD card with the aim of making a fresh install of PureOS. I am trying this because the phone’s been malfunctioning since I tried to install Anbox. Since that time, I have been unable to successfully update via the PureOS Store or via apt.
Here’s what I’ve tried for booting from an SD card with a PureOS bootable image:
– Turning off the phone, inserting the card into the tray that also includes the sim card, and turning the phone on again while holding down the volume down button. I have tried every variation of timing with pressing the volume down button that I can think of, but it doesn’t appear to affect the boot: without fail, it proceeds to the disk encryption password of my hard drive as usual, which I assume is past the point of altering the boot order.
– Taking out the SD card and putting it in again.
– Inserting the SD card into a USB-C adapter and plugging that into the USB-C port of the phone. (I have since read that the phone can’t be booted from that port).
–Verifying that the hash of the .iso file used in making the bootable SD card is what the download website says it should be.
–Praying.
I saw FranklyFlawless’ instructions about reflashing the Librem 5 with a new Byzantium image but I run into issues with this at step one: I can’t successfully install uuu. When I attempt it, I get errors saying I have unmet dependencies, and trying to fix those with sudo apt --fix-broken install gets an error in the certificate validation: “Certificate validation failed: The certificate is NOT trusted. The certificate chain uses not yet valid certificate. Could not handshake: error in the certificate verification. [IP: 49.13.57.135 443]”
Any input would be appreciated! I’m out of ideas.
