Changing the bootup screens on Lumia?

[Keith White Jr]

Is there a way to remove the AT&T logo that pops up when my 1520 boots? Also, if possible, is there a way to replace the Nokia logo with a Microsoft logo?

its a simple png image somewhere in windows folder, enable full FS access and look for it, its even called "ATT" I think, I've seen people deleting it and contrary to what I would expect they didn't get a bootloop or bsod for a missing file
