Help Can't manually install 4.5.621 update on non-contract Droid X

[NeutiquamErro]

Hey, all. I'm trying to manually install the 4.5.621 update on my Droid X using SwiFTP. Anytime I try to update using Settings --> About Phone --> System Updates, I'm told that I'm already up to date, but I know for a fact this isn't the case.

By the way, I bought my phone off of Amazon without a contract, so I'm doing all of this via WiFi.

After I place the file in the SDCard folder (renamed "update.zip) and initiate installation, I receive this message:
Finding update package...
Opening update package...
Verifying update package...
Installing update...
asset failed: file_getprop(?/system/build.prop", "ro.build.fingerprint") == "verizon/shadow_vzw/cdma_shadow:2.3.3/4.5_57_DX5-35/110820:user/release-keys" I I file_getprop("/system/build.prop", "ro.build.fiingerprint") == "verizon/shadow_vzw/cdma_shadow:2.3.4/4.5.1_57_DX8-51/120111:user/release-keys"
E:Error in /tmp/sideload/package.zip
(Status 7)
Installation aborted.

Can anyone tell me what to do? I already tried a factory reset and I still get the same message. Thanks in advance.

If you really want 621, you could always SBF it. See the stickies in the All Things Root section for instructions. I know the SBF file was posted somewhere in there, but not sure where.

Those are Milestone, not Droid X.

Thank you for the replies! I appreciate your advice. I'm a recent convert from the Apple camp, so I'm not wise in the ways of RDS Lite. Can you offer a brief description of how to access that program, and how to load the .sbf file onto my phone? You guys have been very helpful!

Here's the instructions on how to SBF:

I'll see if I can find a 621 SBF file link, but if you ever think you might possibly want to root, use the 602 SBF instead. There's no easy way to root 621.

Edit: Here's a source for the 621 SBF:

(Note: you want the SBF, not the update)

You are such a champ. I followed your links and now I have Liberty 3.0 running on my Droid X. Thank you so much for taking the time to help!
