Are you sure you download from correct site (or you're typo)? There's no nightly build in 2021-01-24 for mata, I see the build on 2021-01-25I just installed lineage 17.1 on my Essential PH-1 (Mata). It seems to work great, however after I unplug the device from usb and reboot, it starts powering its self down, giving me the "Can't load android system. Your data may be corrupt." error. I have tried using the 2021-01-24 nightly from the lineageos download page, and 2021-01-17 build from microg. I would install an older version, but can not seem to find them anywhere. I have been trying to get this working for the past 2 days with no luck.
You can get the older version from original LOS
