OK I have been reading so may threads post all over the place and I am just spinning here

I am trying to update the OTA on my Droidx, but it always fails at the end.
Current About info-
Version: 2.2
Baseband: BP_C_01.09.07P
ERI: 5
PRL: 52105

As far as I can remember all the changes have been undone (Kernel, Bootanimation, and so on).
I have also restored my device via the privacy option, so.

I hit the search key while the update is going, and this is what I get when it stops:

Verifying Current System...
assert failed: apply_patch_ check("/system/framework/framework-res.apk (a lot of #'s)
E:Error in /cache/Blur_Version.2.3.151.MB810.Verizon.en.US.zip
Installation aborted

Back to my opening statement that I am spinning: I figure that I will have to reflash back to a stock SBF BUT I cant figure out which is the stock SBS for my device and present OS.

A few have warnings that if you use the wrong one you can brick the device.

Can you direct me as to where to find the correct DBF?
