Trying to update the firmware from atmega2560 to atmega16u2

I have arduino mega atmega2560 and wanted to use it as leonardo( trying to make arduino cursor ,keyboard)and for that I was trying to update the firmware using FLIP software by ATMEL .
I connected the arduino , went to the DFU mode of the arduino by shorting the two pins of arduino, updated the firmware.
now the issue is my arduino ide no longer the recognize the port number of my connected arduino.
I am attaching the pics of device manager, how it look when i connect my arduino now.

For what it's worth, I had no luck with FLIP lately. It killed the DFU in a few 32u4 chips before I gave up on it -- like you, the devices disappeared from device manager. I also had problems with Atmel tools, apparently because the newer version of avrdude working behind the Arduino IDE is looking for different drivers than it used to.

I ended up using an Arduino Uno as ISP to load in the bootloader, which worked great.
