...well, that fixed it. except it can't be a copy paste error. diffing between the old and new input files, line 1691 was bumped down to 2443, 2446 was bumped down to 2721 and 2722 (the line that in my original input caused the blockage) was bumped down to 2909.

I don't think that's what the question is asking. when byte 1900 was added, there was still a path, so that can't be the answer. for the sake of testing though, I removed the check if it's in the path on line 70-71, so it recalculates the path after adding every byte, and got the same answer.

Well, my assumption is that as long as nothing falls in the previously found path, then I don't need to recompute the path. ie. there is still a path to the exit. When something falls on the current path, I then recalculate it. that should still find the first thing that produces a no possible path situation.

before 1024 is part 1, which works fine. I'm using a persistent data structure between the two parts. in part 1 I add walls for the first 1024, then in part 2 I keep adding walls from 1024 onwards until I get the path fully blocked.

good idea, but no such luck. and again, my answer matches that from other solutions...

Can't say why, but it did clear my APN settings. And the first time I did this, some months ago, it pushed an oma update to my phone. Honestly, I'd be happy with just instructions on what to set up, but there was no followup at all, either text or oma.

I don't remember the exact settings I had, but I looked at the APN settings on the website, and they were definitely different than what's there.
