How to Update Your iPhone 4 Without Upgrading the Baseband (Windows) 4.3.1

how with bb 02.10.04

Hi. I would like to know if this procedure works to upgrade an iphone 4 from IOS 4.3.5 to IOS 5??? Thanks... JC

Hi, I have upgraded to 4.3.3 using this tutorial, everything worked as given. However, after using FixRecovery43.exe, I am not able to get out of emergency screen. Can any one tell me how to get out of emergency screen? Thanks,

Does this also apply to update to 4.3.3, I can see in tinyumbrella that my SHSH is saved for 4.3.3, my guess would be to say it is safe to do so. But I may be wrong.

I can confirm that this works also on 4.3.3

how did u get it to work with 4.3.1? Can you give us step by step what you did and where you get the files? Thanks

Is this method work for all future ios versions????

I can confirm that this works with ios 4.3.2 also, make sure you are running tiny umbrella in the back ground and have TSS server running!! The steps for upgrading to 4.3.2 without upgrading the baseband is the same as 4.3.1.

Worked for me after trying loads of other sugestons...thanks!!

it seem like 4.3.2 is out but I like to keep my baseband so I am updating it to 4.3.1, the problem is that I am getting 16XX error which then I went back to step 5 but it like a loop getting the same 16xx error. I have TSS server running, and I try using Tinyumbrella 4.3 and 4.32 same problem. I also have try ignoring the error 16xx and ran the fix Recovery but I end up at the restore screen in Itune. I got this working before on another iphone. Anybody know what I am doing wrong?

I get the same loop. Let me know if you got an answer for this problem yet.

im having this same issue, were you able to fix it ?
