hey everyone I am trying to make my uno be recognized as a midi device and was trying to follow this tutorial: https://www.youtube.com/watch?v=-bCz2I9SMAA
but shorting the two pins that are shown in the video does not put my arduino in the DFU mode and only restarts it and it goes back to working exactly like before.
I have also tried to upload the hex file through Atmel Flip but when I try to set a usb port I get the "AtLibUsbDfu.dll not found." error.
I have attached the pictures of my board bellow.
Please extract the techmical information in the video and present it here.
the video suggests you can enter the dfu mode by simply shorting the pins 5 and 6 (the two pins closes to the red button on my board) but that's not the case for my board. I will add a picture to show which pins I mean
Sorry but no such pins on my UNO boards.

On your board ("Rev 1"?), it looks like you have a somewhat more complicated procedure.

mine is Rev 3 or at least that's what the back of my board says (refer to the second picture from the first post). so I'm a little skeptical to try the second way mentioned in the post you sent. is there anyway shorting crystal(?) and then shorting the pins on the later revisions might mess something up or damage anything?
okay so after some searching I found this topic:
( Arduino UNO R3 atmega16u2 can't enter DFU mode )
with a quite similar situation and board to mine and the problem was that their atmega16u2 was either not programmed or improperly programmed, so I'm probably going to try and reprogram my chip with another uno but before I do it I need to know something and that is whether I can use my UNO with the ch340 serial com chip as an ICSP programmer to burn the bootloader into my atmega16u2 Uno or not? I have not found anything on this online.
appreciate all your answers and opinions on this
