Interesting. thanx

...but please don't use 7210S anymore for screenshots, buy a real camera instead

I signed in on this forums to do one thing and thats to show you guys that this method works!

I updated my firmware to 4.0 and I wanted to go back to 3.1.3. All the steps mentioned here are correct.


Troubleshooting:
error 3### - you need to place the 76.####### gs.apple.com at the host file (check this thread someone mentioned it already)
After doing that --- restore again to 3.1.3 then youll get the RIGHT error which is 1015 i think.

libUSB --- this f'd my laptop up cause I didnt follow the instructions. MAKE SURE you open the libusb INSTALLER using windows xp compatibility mode otherwise youll lose all your drivers (wifi/cd/usb/etc).

Once you install this then do the iReb fix recovery loop and viola! youll be able to recover and activate it in iTunes as 3.1.3

So to all those who said fake! Learn to troubleshoot. Took me hours but I did it

sorry, I was lazy in putting that. You could find the step by step (with pic) in the previous page but for brevity...

go to c: then windows then system32 then drivers then etc. so thats c:\windows\system32\drivers\etc

after you find hosts file open it using notepad then paste "74.208.10.249 gs.apple.com" to the last line

it should look like

127.0.0.1 localhost
::1 localhost
74.208.10.249 gs.apple.com <--- last line

hope this helps and good luck! I wasted 4-6 hours trying to figure this out hahaha

[Zarrkal]

Maybe the reason why you cant downgrade from new boot is because your phone came out with the new boot?

My 3gs is almost a year so I went through all the versions before 4.0.

I personally upgraded to 4.0 and painstakingly downgraded to 3.1.3 through the steps provided.

Again, please post the steps you made so I can help you downgrade your firmware
