How to downgrade after ios 5 update?

[calvin89]

Apple has stopped signing 4.3.5, so to answer your question about downgrading your bb for iphone 4 from bb 04.11.xx to 04.10.xx is impossible as of today.

oh no
you mentioned some other way - shsh blob ?
please help me
i hope there is still some way

What took you so long, you should have done it by today. I remember helping you about 2 days ago...

If you try and restore to stock 4.3.5 using 4.3.5 blob, you will end up in Dfu mode.

Preserve Baseband on iPhone 4 during iOS 5 Upgrade – Windows Users | Iphone 4 Jailbreak.org

"You can only downgrade your firmware if you have the blob and use custom firmware"

how exactly can i do that- please explain

Yes, you can downgrade using custom firmware if you have the blob but not your baseband. Gevey sim is not going to work on 04.11.00 bb
To downgrade :
Build your custom firmware.
Put iphone into pwned dfu mode
Start tss server with saved blob
Run itunes and restoe to cfw of whatever you built.

Restoring to custom firmare doesn't flash baseband, your baseband is not going to change . Just wait for some new sim in the near future or sell this iphone and buy a factory unlocked , solve all your problem.

oh no
are you absolutly sure that its impossible to change bb or downgrade my iphone4 now
i screwed up men

I am positive unless if you can ask some insider at apple company to flip the switch for you to restore to 4.3.5 , didn't i tell you before that you should do it while apple still signs 4.3.5 cos 4.3.4 and 4.3.5 bb are the same.


I just upgraded my baseband too but intentionally as i have a factory unlocked iphone.
Did you buy this iphone under contract ? You can contact the person who has contract , pay him like 50 if he could ask his provider to unlock it permanently

i guess i have to wait for hackers to come up with an solution
but thank you so much for all your help
