Did you adjust the contrast after fitting the new display ?
Did the LEDs light up as normal after you had th new display in, but before
you installed the bootloader update ?
If so, you probably just need to adjust the contrast, then re-install the
main P3 code instead of the bootloader update.
The update does not light any LEDs, it only shows text on the display.
The contrast trimmer is next to the LCD connector on the mainboard.
It should be at roughly half-past-two for an LCD display.
