cancel customizations?

[Willy]

Hey all, I'm flashing my VX6900 for the first time, and I think I have it all planned out, but I still have a couple questions that I can't seem to find anywhere.

I was planning on flashing the official VZW 6.1 ROM and not letting customizations run, since a lot of people are having problems with getting GPS if they do. Everyone says to cancel the customizations, but I've never seen an exact explanation of how. When I flash will it say it is running customizations, and at that point what do I do? Hit the reset button with the stylus, or do the full camera button + power + reset? In the official readme there are screenshots but none of them say anything about customizations, just one progress bar saying the ROM is being updated.

Will it then boot normally into WM 6.1 so i can run the unlocker, or will it attempt to run the customizations again?

Then I run the unlocker, and do the hard reset (camera+power+reset)?

Then once it is in the tri-color screen, I can flash a custom ROM and do the aGPS fix. Did I miss anything extremely important. It's kinda hard to keep track of everything when you are piecing together info from 4-5 different threads that are constantly changing.

Thanks for any help. I just wanna make sure everything is planned out, and minimize surprises.
