Starting with a bone stock N5, I unlock the bootloader (I guess technically it was already unlocked the second time I had this problem), then push TWRP over via fastboot. At this point, I do a Nandroid of "stock" and save it. Then I flash PACman ROM and run with that for a bit, one time with the Elemental kernel, the other time with whatever kernel PAC comes with.
So in an attempt to go back to stock due to some LTE issues with PAC, I boot into TWRP, select restore, then choose my original "stock" nandroid. It restores fine as well as I can tell with TWRP, but when I go to boot it just gets stuck on the Google color splash screen (the dots coming together).
Any thoughts on what I'm doing wrong here. I don't have any problem loading any of my PAC nandroids at this point to get back up and running, but I'd rather not have to go to my computer every time to push a factory image.
