It helped me (yesterday) to select a beta-version of iOS4 GM and using redsn0w_0.9.5b5-1.

With this combination the jailbreaking was possible

eucherio July 10, 2010, 7:01 am

I installed Redsn0w but I can’t find the IPSW file.

help me please.

Mnose July 15, 2010, 10:05 am

All these jailbreakers are ignoring this problem..Unable to recognized the IPSW….

sPeshL_k October 21, 2010, 10:02 am

re download the firmware (ur ios software just google it and u will find it on jailbreak sites) dont run it save it then make a folder on your desktop put it there when redsnow askes to browse for file folder point it to that one and open it up click the os u have just put there (has to b the same one on your phone) then follow red snow itll take bout 10 15 min its very easy

freebird October 22, 2010, 12:09 pm

I did that, I created a folder with redsn0w_win_0.9.5b5-5 and the iPhone1,2_4.0_8A293_Restore.ipsw file in it and then I followed the steps after launching redsnow, selected the ipsw file,and after the jailbreak procedure, I get the following message.
Restore Required….connect to Itunes and restore…..etc. So it appears that jailbreak has not occured, though I did see a white flash screen, and then the pineapple logo which remained till the jailbreaking was in progress, but after reboot, I get the “Connect to Itunes” window, and then I get the message “restore required” and so on. I already had IOS 4.1 on it, is that creating a conflict?And right now, I see that itunes has begun to restore my phone, and is taking its weet time, and in the INFO tab I see 4.1 as the OS version, although I ran the IOS4.0 restore, using redsnow.
might hectic, but I do expect to get there soon, lets see what Itunes does to my phone now that it is restoring it back. Perhaps this will cancel the jailbreak or nullify it or what? waiting to see what happens 🙂

I have a iphone 3G with 3.1.3 and basseband 5.12 I used spirit to jailbreak my iphone can i upgrade to new itunes 9.2 and download the new OS 4 and then run redsn0w 0.9.5 to re jailbreak my iphone 3G

iPhoneHeat June 23, 2010, 7:29 am

why not jailbreak OS 3.1.3 with RedSn0w.. and then unlock with ultraSn0w
or you can go for OS 4.0 and then jailbreak using the guide above and then unlock with ultraSn0w

july23 June 27, 2010, 11:29 am

i just upgrade my iphone 3g version 3.1.2 to ios 4 thru itunes 9.2, but i tried to jailbreak it but i cant. i already downloaded redsnow_win_0.9.5b5-4 and open it, the problem is that i cannot find the ios 4 firmware ipsw file. And i try another way, i downloaded another iphone1,2_4.0_8A293_Restore.ipsw and save it on the desktop. After that i open again the redsnow and browse the ipsw file from desktop and it fails, it says that “Unable to recognize specified IPSW”. I think i made a mistake, so anyone can help me with this?

iPhoneHeat June 27, 2010, 1:54 pm

are you sure it’s redsnow_win_0.9.5b5-4?

Formanite July 1, 2010, 4:11 pm

What the Heck !!! I downloaded the Official iOS 4 Firmware then i updated my iPhone 3G after updating my phone atomatically activated without any jailbreak …….

Hely_999 July 4, 2010, 6:53 pm

Hey there,
I have a 3G iphone.
So, I do exactly what you tell me, but… Redsn0w will always stick at “Uploading Ramdisk”, at one point or another, for ages. And I mean, Ieft it for a few hours once to see if anything would happen, but nothing. Why does this happen and what to do? :/

callme_dane July 5, 2010, 6:22 am

Hello iPhoneheat!
I have complete jailbreak and unlock my iphone 3G V 3.1.2 to 4.0 by using Redsn0w with a success, and everything is Ok.
But the only problem is I can not find the Cellular Data Network (in Setting->General->Network). So, I can’t connect to internet by using the Simcard.
Could you please help me?

iPhoneHeat July 5, 2010, 1:31 pm

try turning Air Plane mode on/off.. Reboot
or reinstall ultraSn0w
