Oh dear, it looks like a hardware fault. Before the e-ink drivers are loaded, the PMIC gives an error - for the DISPLAY regulator. That is bad - the PMIC is the power source (or better phrased: the power distribution chip). So likely, the e-ink system does not get any power, hence no wonder that the driver for it fails, too.

If it is open anyway, have a close look if some traces have been shortened. Maybe the cable for the display isn't fit correctly to its socket (is there any?).

So yes, hardware fault, unfortunately.
