Downgrade iOS 4.0.2 To 4.0.1 iPhone 4, 3GS Without SHSH Blobs

Enmity

******This worrked for me!!!!!!********
Ok. I never usually comment but i feel impelled to help since in the past i gained so much from others! My iphone 3gs was never ever jb or backedup

1. I dont know how but somehow get ur 3gs to to be in recovery mode.

2. JUST RENAME THE 4.0.1 file to be the same as the as the 4.0.2 ipsw file. Dont copy files or replace files or edit files. Just change the name of the 4.0.1 file to be 4.0.2 file. Copy and paste the whole name to make it easier.

3. Change the host file as u would like everyone else to the cydia srvers. Look above and u will see instructions.

4. Itunes will tell u that u are in recovery mode. Hold down option or alt and click on restore. You will then select the file you just renamed.

5. It will ask you if you want to restore 4.0.1 NOT 4.0.2. I know you renamed it but it will display 4.0.1. Just say yes
since this what you want anyway.

6. It should restore without a problem and the last few 20% takes longer for some reason.

7. For me after it restored it still went to recoverey mode but i used blackra1n to get out of it. If you have a better way do it. My other friends didnt go into recovery mode after the restore SO DONT FREAK OUT when it says connect to itunes aftere the recovery.

8 voila u will be in 4.0.1 and jailbreame.com that 3gs. Not tried on ip4 so dont ask me.

my dear friend u were able to downgrade ur phone becos u add shsh saved already in cydia. dont disturb us here.apple is no more signing version 4.0.2 anymore. they are now signing only 4.1 firmware. thanks

still err 3194 sir
no solution

do u think apple allowed u downgrade the fw version by renaming file...what a ? if u have shsh backup you dont need rename it too

no solution wait new jb v4.1

this is fake i have try this method no way .......... just wait for 4.1 jb

this is fake........

not working .. tested for 3gs and 4... even with trying so for rename the as 4.1 (8B117)

even with saving the shsh for 4.1 for the same device and tring to flash the fixed file..

its just an idea ... think more deep maybe u can reach somthing ... better than saying FAKE..

no solution.........................

bro are you joking its not posible

If you havent testest it successfully why are you wasting time and space on this valuable forum

regards

doesn't work~ waste of time.
