Yes sir, that works perfect.
Although recently, I simply used the 5V directly from the USB port on the USBJTAG NT to simplify from having to use a secondary cable.
Have you ever had any problems using 5v? most of the flash chips are only rated for vcc max of 3.6v~ but I'm guessing since it worked for you that they are 5v tolerant on the vcc pin.
Also, I was thinking of older, pre D3 modems having 8 pin flash chips, had a bit of a brain fart
Anyhow, great tutorial, I'm definitely going to give it a try with a modem I have laying around, sure beats pulling the flash chip.
