Default login: `user` / `147147` (same as official postmarketOS images —
change it). **Never re-lock the bootloader** with a custom image installed.
> [!WARNING]
> **Back up your modem's NV partitions before flashing.** Flash sessions have
> been observed to zero `modemst1`/`modemst2` on this device, after which the
> modem reports no IMEI and neither SIM slot answers (`no-atr-received`) —
> including the eSIM. The profiles themselves are safe in the eUICC, but only
> a restore of working `modemst` images brings access back; stock Android
> re-provisions them on boot, postmarketOS cannot. Before your first flash:
> `dd` both partitions to files from a rooted stock system (or from a running
> pmOS: `/dev/disk/by-partlabel/modemst1` and `modemst2`) and keep them
> forever. Restore with `dd` in the other direction, then reboot.
