Here's my estimate of the trajectory assuming a 500 km apogee and a 55 deg inclination
The Iranian Space Agency posted a tracking movie on https://www.instagram.com/p/BssEB3Wg_3E/
Google translation from the text: "The astronomers of the Space Organization of Iran first planned and calculated for the use of optical equipment for satellite observation at a calculated time and place (elevation of 10 degrees and side 131 degrees)."
There is also a long post about the data received https://www.instagram.com/p/Bsswh0jgx5n/
Yeah, can't tell too much without knowing the observing location, but interesting
The 'long post' at least confirms the sat separated from the final stage and transmitted data to the ground
during its brief flight.

I find it difficult to reconcile the 5 min in the above post with the idea of a stage 3 failure.
The only sensible launch profile is for stage 2 to reach a 500 km apogee and it's hard to do that and reenter only
5 min after launch.

Maybe the five minutes is the amount of time before loss of downlink?

Iran has a habit of hiding launch failure. In the past, it boasted of successful launches despite the fact the launch was a failure and fooled its people.
