There's definitely something wrong with the 5153 Blue.
I just updated, and of the ten patches I 'saved', the one with that amp locks up the unit. I've tried all the various resets, nothing helps. No matter how I reference the patch, through AE or from the front panel, it locks up the Axe and usually gives a blank screen.
I've loaded the patch from several different saved files, and it still works with my non-XL (still on 14).
EDIT - I got the patch working, but not with that amp. I loaded the preset with the Bot. When I switch to the preset, I have about a second, maybe two, before the unit locks up. I was able to select the preset, tap 'EDIT' quickly to get to the amp block, page back, and select a different amp - all before it locked up. Selecting a different amp fixes the problem and the unit doesn't lock up. BUT, if I select the 5153 blue from the working patch, it locks immediately.
And yes, I've tried parameter reset.
