AVRKey wrong flash - can't enter update mode anymore –

Guys,
I was messing around with .hex files for my AVRKey (atmega32u2), trying to invert active LEDS colors. Everything was fine until I flashed the psgroove.hex attached with Flip 3.4.2. Now my AVRKey is detected only as Generic USB HUB, and it doesn't enter update mode anymore, no matter how many times I press the dongle's update button.
Yea AVR DFU Bootloader is a generic term for any microcontroller device that is an AVR device, and that device is in "program" mode. Meaning you can write hex code to it. That looks like a 162 so ATMEGA32U2 should have worked fine. I dunno if something went wrong when you were editing for the LED changes you wanted or not. To be honest that prolly would not make a difference unless some other part of the code may have been edited by mistake.
AVR keys don't have a button for update mode. You have to insert and remove them 2 or 3 times for them to go into update mode. You have something else.
It looks similar, but I think I have the PS3 Replica instead, which has the same atmega32u2. I took a closer picture of it:
I've managed to update it by pushing the button harder. But I think I'll have problems in future with this button. Will it be enough to short-circuitry button solderings if it comes completely broken?
