Here's some Verizon specific instructions. Most of this information is taken from
this thread. Many thanks to kocoman for providing these instructions, I just summarized and added a couple things for Verizon.
1) Download kocoman's 755 ROM file from:
http://rapidshare.com/files/88032709...p1-04.rar.html
2) Download the Verizon Treo700p_-1.10-VZW update from:
http://palmone.r3h.net/downloads.pal...pdate-rev1.zip
3) Unzip both files
4) Copy the entire unzipped contents of the 755 ROM file to an SD card (blank or not) in the /ROM folder.
5) From the
700p update unzipped folder, copy the following files to the /PALM/Launcher folder on the SD card: "CDMAFirmwareUpdater.bprc", "CDMAFirmwareUpdater_enUS.oprc", "RomUpdater.bprc", & "RomUpdater_enUS.oprc" and then rename each of the files to have just the .prc extension.
6) Backup any information on the phone and make sure the battery is fully charged & plugged in before you do the update.
7) put the SD card into the phone, and run the "RomUpdater" application, it should say "VENT" and "DVT", if you do not see that DVT, do not flash!!! (VERY IMPORTANT)
8) type "ventura" and enter
9) Wait for the update to finish (about 20 minutes)
10) To get the phone to work, you have to restore the Verizon PRL. Do this by running the CDMA Updater application from the card. Hit the menu button, and go to debug. Uncheck everything but "Update PRL" and hit OK, then tap Update Now. After that finishes, you should be able to make and receive phone calls like normal BUT you will not be able to do *228 to update the PRL.
11) Get rid of the my treo auto update. Open MyTreo, hit the menu button, and select update. Change Auto-Update to Off.
12) (Optional) You may want to hide some of those Sprint applications that won't work like SprintTV and SprintStore. Go to
this thread and download that application, then you can hide apps by going to the applications item in preferences.
13) Your data connection may or may not work after the update. Mine worked fine, but I already had two different connections in Network preferences. You may need to create a duplicate service, with dummy settings, and then choose the original for the connection to work.
14) Now you can start to restore your data and applications to the phone. I would advise going program by program to make sure you don't go into a reset loop, and besides, this will give you a chance to get rid of those apps that you weren't really using and were just taking up space.
