Clogged somewhere but I don't know where

No filament is extruding at all. Here is what I've tried:

Super heat the hot end (275 or something)

Cold pull - didn't work because filament couldn't get down far enough to heat up

Push through - I lightly tapped a metal rod down into the filament hole and it did go down but not enough before I ran out of rod to hammer

I tried to remove the nozzle but the bolt is stuck. I don't know if I need to do this. 

Is there anything else I can try?

To find out where the clog is:

'Load' filament, it will fail, mark the filament (sharpie) at the point where it enters the extruder, unload the filament.

Offer up the filament to the extruder using the mark to show how far down the blockage is...

*IF* the blockage is just below the bondtech gears you may be able to fish it out by opening the idler door and using tweezers or a bit of bent wire.

*IF* it is in the hotend then heat the hotend to printing temperature and, with the idler open, push down some filament manually; it should run through after an initial difficulty.

If that didn't work, remove the nozzle as on: https://help.prusa3d.com/en/article/changing-or-replacing-the-nozzle-mk2-5s-mk3s-mk3s_2069    and manually feed filament again.

And if that didn't work come back with details.

Cheerio,
