Notes:
After installing the update.zip to go back to stock i choose the option not to install root. Once booted i enabled adb and connected to wifi. Got the update notification for my account and B05 and installed both. Rebooted back to stock recovery and installed the new B06 update. Verified in about phone section that it is indeed updated to B06. The boot animation is the stock virgin mobile / zte animation still. I never connected to the play store to update apps. If you want me to do it again with root and updated apps just let me know as i have some time this morning. By the way my phone is not activated. It was once before but i get errors when trying to update prl, profile, zte software, firmware. How i got the update notice before others still not sure. After rebooting again there was an update for voicemail.
Get the B06 update.zip here!
