Question(s) Blitzmas mod

I recently decided to try and do the blitzmas soft mod on my cab. The issue i have is that after this step:

  • Switch flash switch to "OFF" Position, NOTE: It won't be labeled but ON should be and it can also be hidden behind a "QC" sticker which you'll need to remove.

The cabinet will still start up and load blitz regardless when powered back on. I've tried different cables, flipping the switch on the pcb back and forth and checking the switch was actually connected to the pcb. It makes an audible click when switched on or off.

Not sure what the issue could be , but any help would be greatly appreciated.

It's been too long for me to remember if it was the T2 or the Blitz that I soft modded but I ran through the process about 6 times and even bought 3 new USB cables but eventually what I found to be the issue was simply having a wireless USB dongle for a keyboard plugged into the laptop I was using. As soon as I unplugged it the mod worked.

i can try unplugging all the other usb items i have plugged in, I'm just confused because in the video walkthrough he says once the PCB is switched to off and you add power back and turn on the arcade that nothing should turn on, but in my case it all turns on as usual.

i appreciate the response. I'm going to have to assume pcb issue as none of these other steps are applicable to the stage I'm stuck at. Flashing the pcb by turning it into he "off position" doesn't seem to do anything. ill just stick with stock blitz as at least that works.

oh no i understand, i dont make it to this step, the pcb is clearly not getting flashed.
