This is just a long shot pass to left field. and this happened to me. 
My flywheel key was sheared so no matter what i did to set timing i had a hard stop like you spoke about.  Only until i removed flywheel and found keyway sheared did i truly find out the problem.
Did you put something down spark plug hole and turn over very slowly to indicate that when you hit the T mark the piston was truly at TDC ,   how I found my issue was the piston was already on its way back down when the alignment mark showed up. once again, just thinking out loud.  Before i would pull that top end id pull the flywheel ?  good luck

Were you on the compression stroke ? , 2 revolutions to the flywheel equal 4 strokes of the piston.
Did you hold your finger over spark plug hole ? to make sure your on compression.    wonder if that new exhaust camshaft you put in not working,
Have you turned over with spark plug out to make sure spark is good ?
have you taken compression test yet ?
So when you put on T and on compression stroke with the dots on camshaft indicators straight up you adjusted the valve lash cold to .004 ?
When you turn over by hand with 19mm on flywheel nut what happens ?

This is a 700i engine, the 500i engine flywheel gear might come off with the flywheel ?

top left, that is the starter reduction gear, could be stripped.  gasket will be around $45, starter reduction gear, if stripped ?  if it has to be order from Taiwan, maybe a month wait ?
best of luck

does your stator cover look like this

see that little plug to the left of the oil fill plug

this is the timing flywheel inspection plug

way left with screwdriver slot in it

this manual will also show you what plug to take out to inpect for flywheel timing etc

Don't open up or take off side cover just to check to see if your piston at TDC, just take out the inspection plug, I sent you the manual and posted pics.  if you take that side cover off youll need a new gasket and your hours down with labor, if your after that 19mm socket nut, that on the side of the stator cover, there is a big allen that goes into in, its about a 3 " circle diameter, take that off you will see the nut, my flywheel had a sprag clutch on it, so only turn one way.

theres a little plug about 1" diameter on the side stator cover, take out and then you can see flywheel turn

My first reply was for a UXV 700i single cam, this has the hashmarks at the sprocket side of the camshaft, to see take off cover and pop up that little end cap, 2 hash marks must be horizontal with TDC piston at compression stroke,  the 700i has a dash on the flywheel

For Dual cam,  then line up compression TDC piston and make sure the dots are TDC for both camshafts,  then make adjustments.  I think for the 500i there is a T on the flywheel, if so , use the T , with inspection plug out line up with stator cover mark with T on flywheel.  Also I took out cam chain tensioner prior to removing sprocket and cam chain. Theres an inspection plup on stator cover about 1" diameter for lining up flywheel to cover marks.

If you have to take off side stator cover for any reason do NOT turn over engine, the starter reduction gear uses the stator cover as pin for the reduction starter gear.

always turn over first by hand to avoid bending valves etc if not adjusted correctly.

when did the no sparks start ?

thanks and wish you all the luck
