Motorola Droid :: NON ROOTED FRG22 Upgrade Possible?

Let me begin by saying I am non rooted. I do not wish to root.I apoligize in advance if this is a repeat but I have yet to find an answer anywhere regarding this issue.Let me also say I am sorry in advance for my horrid ghrammer and spelling. On to the show.I have searched and scoured and burned my eyeballs trying to find a way to upgrade to FRG22. I am one of those who have been having lag and issues with my 2.2 upgrade. (it is sexy as hell though to look at and flash is ok. Not awesome of course. Fast moving video and demanding games and FLASH based video arnt the greatest, some damn choppy enough to make ur stomach turn but its a start and further than we were a month ago) Anyways back to the task at hand.I have downloaded the FRG22-Release or ODEXED version of FRG22 and wish to install it on my Droid. I have downloaded 2 zip files for this and renamed them update.zip and tried it with them in their original file names. I get the e:verification sig error and install aborted each time. I also did not have BOTH on the phone at the same time. IF i applied one I removed the other.

I noticed between these 2 they are different file sizes as well so I dont know if that has anything to do with it. I followed Tridents Instructions to get to the menu to install the update. And YES i did use the FRG22 zip files to update not the original froyo release trident has as the first post on his forced update.I would just like to know 2 things. 1.)Is it possible for NON ROOTED users to update to FRG22. and 2.) If it is and I have the correct file. Which do I use and what am I doing wrong to not make this work out for myself?
