Custom ipsw with RedSnow

Hello All,

I am trying to restore my iphone 4.3.3 OS. I turned my iphone into dfu mode and tried to restore it with "iPhone3,1_4.3.3_8J2_Restore.ipsw". But it failed due to some errors like 1600, 3194 etc. I bypassed 3194 these errors using TinyUmbrella. And for 1600 I downloaded a custom ipsw "iPhone3,1_4.3.3_8J2_Custom_ACTIVATED_pwangetool4. 3.3.1" and used Redsnow to put my phone in pwned dfu mode and patch the kernel so that it bypasses the 1600 error.

But the problem is that I used all the versions of RedSnow 0.9.6 RC(15,16,17,18,19), all of these cannot recognize the custom ipsw. However it can recognize the original ipsw i.e. "iPhone3,1_4.3.3_8J2_Restore.ipsw". But when it patches its kernel and I SHIFT + Restore it in itunes everything goes fine and after a while it says error 1013 uknown error occured. And now my phone is permanently in dfu mode.

I am using MAC, and iREB is not available for mac that is why I am using RedSnow.


Anybody please help me in restoring its OS either original or Custom JailBroken.


TIA

Thanks for the help. It worked and now itunes restored my phone. At the end of restore itunes prompted that this phone is restored to factory settings and is restarting, leave it plugged in. But my device disconnected and it looked like its restarting and then itunes again said, this device is in recovery mode. So I think its still in dfu mode.

How to exit it from dfu? I tried Home + power button but it didnt work.


Thanks for helping me in restoring my device

Hey finally I found out that I didn't save shsh blobs for 4.3.3, that is why its in dfu mode.

Any idea what should I do in order to get my device back except for upgrading it to latest firmware?

Which iOS is till singed by apple? and whats the significance of 74.208..... gs.apple.com in hosts file? Is it a fake server, so it should sign any ios?
