mainly getting to the spot you needed to be to insert the updated calz files, you know click on programs, then efi live, then 7.5, then file 35, open the custom file and unzip the updated calz....i feel dumb now cuz i could breeze right through it now, the biggest hang up i had was updating the v2....had to update the firmware 3 times from oldest to newest to get it to be recognized, and then realized that to start the update for the bootblock was on the v2 handheld itself, pretty much self explanitory after that, just alot of reading and pming the efi staff with really dumb questions......
