Unable to Flash to LUKS Byzantium Image

[FranklyFlawless]

The list of sequential steps:

1. Use balenaEtcher to flash a PureOS Byzantium image onto a USB drive.
2. Turn off your computer, insert the USB drive into an available USB port, then turn on your computer and select the USB drive to boot PureOS from it.
3. Connect to an Internet access point using either Ethernet or Wi-Fi, open Terminal, then run the following command to fetch the latest package versions:

sudo apt update

4. In the same Terminal window, copy, paste, and execute each command below, one line at a time.

sudo apt install git uuu
git clone https://source.puri.sm/Librem5/librem5-flash-image.git
cd librem5-flash-image
sudo apt build-dep .
sudo ./scripts/librem5-flash-image --udev
./scripts/librem5-flash-image --stable

After the Byzantium image has been downloaded, you will see the following instructions:

Enter the flashing mode by holding volume-up button while turning the phone on.

            If it's not detected, follow these steps:
            - Ensure that the phone is powered off
            - Turn all Hardware-Kill-Switches off
            - Unplug the USB cable if connected
            - Remove battery
            - Hold volume-up button
            - Insert the USB-C cable (red light blinks, no green light)
            - Reinsert the battery (red and green lights constantly on, the script will continue)
            - Release volume-up button

After following those instructions, the Byzantium image will be flashed onto the phone, so during these 10 or so minutes, take a break and grab a ${DRINK_OF_CHOICE} until the procedure is complete.

The --stable argument/flag will default to the LUKS variant. As a reminder, the default passphrase is 123456.
