Can someone upload a zune backup

---

I Need A ZUNE BACKUP of the 7.7004 WP7 OS I want to throw it into the file location (%userprofile%\AppData\Local\Microsoft\Windows Phone Update) and see if Zune will let me downgrade my OS from the 7.7380 to the 7.7004) for some reason zune did not create a backup on my system in this folder when updating mine so if someone could upload a backup that would ROCK!!!!!!!!!!....



NEVERMIND Just Entered USB Bootloader Mode and Reinstalled Original ROM.

Can you do me a solid?

Do you have the original ROM 7.7004 ROM? If so is it ATT capable? I'm having the toughest time getting my phone back to original factory settings after attempting and failing miserably with a mango beta update. Thanks. bafeagle@bafeagle.com
