LG vortex downgrade guide - many thanks to Salem, as much of my guide is copied from his
how to boot vortex into emergency from XDA
after a bit of tweaking I was able to recover the phone by following these steps:

[Setting up your computer]
if you previously downgraded your LG vortex from 2.2.1 to 2.2 chances are good this part is already done
1. download files from following links:
factory flashing software & firmware
optional free un-rar software
2. plug in your phone (even in it's crippled state) it should autorun, and install some USB drivers
3. extract LGNPST.rar and run the LGNPST_General_v1.2_Lab_Version.msi this will setup to the directory C:\LG Electronics
4. copy/move LGNPST.exe to C:\LG Electronics
5. extract the LGNPST_Components rar file, this will make a directory with two MSI files in it - run these.
6. Go to C:/LG Electronics/LGNPST/ and create a folder called ?Model?. Inside that folder, create another folder called ?LGVS660″.
7. Extract LGVS660.rar. Inside this, you?ll find a VRZ folder. There are three files inside this: a .tot file, a .scr file, and a .dll file. Move these all into C:/LG Electronics/LGNPST/Model/LGVS660/ (the folder you just made.
8. If you?re on Windows XP, hit start, click on ?Run?, and run this:
regsvr32 "C:\LG Electronics\LGNPST\Model\LGVS660\VS660.dll"
If you?re on Windows Vistas or 7, hit start, type cmd.exe, right click on cmd.exe when it comes up in the search area, and run it as an administrator. Type in the following and hit enter:
regsvr32 "C:\LG Electronics\LGNPST\Model\LGVS660\VS660.dll"
[setup complete] your computer should now be ready to fix your phone
Contrary to popular opinion on the many forums I perused researching this, I found that this software does *NOT* require your phone to be in debugging mode! it will see your phone if you simply plug it in at this point
[Flashing the phone]
1. go to C:\LG Electronics
2. run lgnpst.exe
3. if you haven't already boot phone and connect USB if the phone was already connected disconnect and reconnect it to make sure the software recognizes it.
Warning! do not disconnect your phone from the cable under ANY circumstances until the software tells you it's safe to do so!
4. try to directly flash phone back to factory. This will require you to select the .tot file from above under where the program is expecting a .bin file (you'll have to manually type in a filter in your file selection box) also select the .scr file in that same directory.
5. if that doesn't work go to the Data menu
6. select 'data recovery'
7. let that work it's magic and it should transfer to 'emergency mode'
8. select the .tot file and then the DLL for your phone
9. flash -- if everything works out your phone will reboot around 60% with everything on it
10. once the phone has booted completely go to menu and set phone to USB debug to stop the 'flashing' process this will allow you to safely disconnect your phone
ENJOY!!!
[emergency flashing]
*WARNING! the following methods are untested! above methods worked for my phone!*
Once again, do not disconnect the phone under ANY circumstances until the software tells you it's okay to do so!!
1. boot the phone in emergency mode by holding volume *up* and the back button at the same time (as I gather from the above mentioned xda post)
2. once in emergency mode it should be safe to continue from step 8. above.
