HOW TO - Downgrade IOS5 Beta Baseband 04.11.08 to 04.10.01

[valentine23k]

You must NOT use TinyUmbrella. You need to get the baseband blobs from Apple. TU can't help with that. It only blocks the process. "stock" firmware just means the standard Apple firmware, not a custom firmware created for jailbreaking or any other purpose.

And you will need to be QUICK! The window will be closed any time now...

Thanks Buddy.....I am able to successfully downgrade to 4.10.01

I tried a lot yesterday ...but i think the problem is with the ipsw i downloaded....this worked like a charm

thanks a lot ...YAYYYYY....

Now I have to find out if Genvy Sim works with iOS 5 with and baseband 4.10.1

I gave you a link to the ipsw firmware files in the first post, along with the steps. What is not clear? Where are you stuck?

Hey hi while i was performin the procedure i was gettin 1604, 1602, 3914 error again and again..
First of all tell me one thin I dont have BLOBS saved on my PC. Den how can i downgrade?

[Rachit]

I just checked my host files. over there last two lines are of gs.apple. I tried removin them and savin the hosts file but was not able to do that. I tried doin that as u have mentioned in ur first post to remove hosts files related to gs.appple.
And i tried doin it other way also thru tiny umbrella, but din succeed. In the advanced tab i unchecked that cydia thin. But my TSS is not workin. ANd yeah in advanced tab there are 5 boxes which all to uncheck.?

[Rachit]

While carryin out this downgradin procedure do we need to keep anythin in mind regarding tinyumbrella o hosts file?
Or i just need to restore the phone by keepin it in DFU mode. M gettin confused as in the beginnin its mentioned that we need to either use tinyumbrella o delete apple related stuff from hosts file..
Main thin i don have SHSHblobs saved on my pc, which i was not aware of..sO I can downgrade?

Man, can you people not read? I followed the instructions in the first post and it worked fine. Did it mention tiny umbrella? No. So why did you use it? If you can't figure this out without asking for someone to repeat the instructions that are already here you should stick to landlines.

i followed all the instruction exactingly as described in this thread, but i could not do it. every time i received error message as attached..

please help, my phone is down
