Don't discourage 13kyl from trying it. His phone is not in the sa me condition as your phone. Specifically his misc partition might have different content than yours.
Oh, sorry...did not mean to imply that...I was just really hopeful.
13kyl, lemme know if / when you are going to try this and need help. I've done the "find the rom.zip" thing after starting the RUU about 5 times now, LOL.
Here's what I did, by the way:
1. Start the RUU running and wait until you get the first screen that asked you to check a box and hit next
2. From Windows Explorer, navigate to your C:\Users\13kyl\AppData\Local\Temp directory (i.e., using whatever real name you use to login into Windows with for "13kyl"
3. In the "Search" box (top, right-hand corner of the screen), enter "rom.zip" and hit return
4. When the "rom.zip" file is found, right click on the file and select "Properties".
5. Mouse over and copy the contents of the "Location:" field that is displayed
6. Paste the copied location contents in another Window Explorer window's address (so that you'll be in better position to replace the rom.zip file)
7. From the "other" Windows Explorer, copy your base root ROM .zip file
8. Return to the Explorer window with the rom.zip location and paste your base root ROM here
9. Delete the rom.zip file
10. Rename the base root ROM file you pasted in step #8 above and rename it to "rom.zip"
11. Make sure you phone is connected via USB and you are booted-up in FASTBOOT mode
12. Start-up your Command Prompt like I mentioned in my prior post above
13. Type "cd c:\android-sdk-windows\tools" (or to where ever you actually have the fastboot.exe file)
14. Type "fastboot oem rebootRUU" and watch your phone change modes
15. Return to the RUU program you started-up in step #1 and proceed with trying to install the base root ROM (now renamed as rom.zip)
Crossing fingers (again, LOL).
Good luck, mate!
