I've been following the online threads for downgrading to V3, towelroot, and then burning V4. The LGFlash gave an error message "FAILED 2188 seconds", but the phone did end up in the AAT Micro 3.0 menu. I was able to reboot the phone and found it is (apparently) now a factory virgin V3 ROM. The phone looks like it's been factory reset (no Boost Mobile skins or apps). All of my data on the phone was erased, including apps, account information, agreements to contracts, etc. but as far as I can tell the SD card has not been affected. I was able to connect to my WiFi network and download towelroot and successfully root the phone, as verified with root checker. Naturally the first update the phone tries to do is back to V4, but I've been careful not to permit that to happen. Obviously I've got to have Boost Mobile reactivate the phone and reinstall all of my data (I *WISH* I had more of it backed up!) I'm holding off on burning the V4 ROM until the phone's reactivated but obviously I am refusing the OTA update. Thoughts? P.S. - one other strange thing. I downloaded Superuser from the Playstore. But it doesn't seem to be doing anything - any root apps (root checker, Samba File Sharing, etc.) installs and runs without Superuser asking me if I want to grant that app permission. That kind of concerns me for obvious reasons.
