4.3.3 restore?

[Timco]

You run TU and download shsh blob. You don't start tsp server yet. Tss server is like a mini server for firmware verification of your restore.

Once you have downloaded your 4.3.3 blob onto TU.
Highlight your device and start tss server, keep it running .
Put iPhone into dfu mode and restore to stock 4.3.3 .
Activate with your sim
Run jailbreakme 3.0 from safari on ur iPhone
Run redsnow just to install iPad bb for unlock

how do I put into dfu mode and restore to 4.3.3? the rest I think I understand....THANKS!!
I run redsnow from pc, right? TU is just running and running. shshs are saved.

Dfu mode: with ur iPhone plug in, hold both buttons for approx 10 secs ( screen turn off) , then release the power button but keep holding the Home button until you hear a beep on ur pc, screen is black.
Now you are ready to run iTunes : shift + restore to stock 4.3.3

Hmmm, do a reboot on ur computer and try again. Try pwned dfu ur iPhone and do the restore . If this doesn't work , try restoring to custom firmware of 4.3.3 from snow breeze 2.7.3, use the pwned dfu tool to put iPhone into dfu mode

It is possible that iTunes 10.4 is not letting you downgrade
