History:Iphone 3gs dissable restore to 4.2.1 official success the my biggest mistake
is to downgrade to 4.1 because i think that is not tethered...

1:restore iphone to 4.2.1 official firmware

2:now when you see itunes saying iphone preparing
for restore and iphone turns in white screen
imediately removed the iphone from the pc then close the itunes

3:now run the tiny umbrealla and you can see now that your iphone is connected

4:run the ECID GRABBER get the ECID of your iphone and copy because we need it
in the next step

5:back to tiny umbrealla click on Manual ECID then paste the ECID that we got from ECID GRABBER
select the model of your iphone then my any name and click Create Custom Device

6:now save your shsh mine i saved 4.2.1 shsh

7:click Start TSS Server open iTunes then click shift restore then browse to 4.2.1 official fimware
at the end you got error 1015 and your iphone now must be in recovery not in DFU...

8:everybody knows how to fix error 1015 run latest version of redsn0w browse to 4.2.1 click on just
enter pawned DFU...close redsn0w

9pen iTunes click shift restore select 4.2.1 custom firmware wait until iTunes finish...

10:now for the jailbreak used redsn0w again and install cydia and ultrasn0w for the unlock

...remember used redsn0w every you reboot the iphone because it tethered...
