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

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.

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?
