Your in the same boat I was in with my brick (last year in April I bricked my first V and had to go out and get another it was so thoroughly bricked). Finally saw that there was enough software and knowledge to give un-bricking it a try.
Try the KP500 method. Even though everything is lined out it still a functioning guide with all download site's working. Go Here:

If that doesn't work, hold off on doing the LGNPST method (this it what I eventually had to use) and it seem to wipe the Emergency mode off of the flash partition it was on, and swaps to many keys around no matter what ROM you install after.
Menu button is the home button, Home button is the menu, no emergency mode,
but at least the buttons seem to be normal in the recovery's flash partition.
With no emergency mode to fall back on, if you mess up, you will never be able to use it as a working phone/computer again.
I'm working on trying to see if I can get it into fastboot mode and straighten the e-mode out with out causing me to perma brick the phone.
Need to read up on it some more, ask around some more, etc., etc.
If you do decide to use the LGNPST method you will have to re-establish your PRL, MEID, and MIN. This requires you to figure out what your MSL is before even going any further. CDMA Workshop no longer has a free version that will allow you to do this, but another old member/dev has stumbled upon a utility that not only figures it out but allows you to easily change your PRL.
Without the MEID you will not be able to use the market or any other app market as they all require your MEID
Al this ^requires a great deal of time and gnashing of teeth, not to mention no e-mode
If you just have to have your phone working and are willing to risk not having an e-mode and possible perma brick let me know. I can point you to all the Guides and Utilities to do so.
