iPhoneHeat March 23, 2010, 3:42 pm

downgrade to OS 3.1.2 if you’ve shsh save via cydia and then jailbreak using sn0wbreeze or anyother tool..
without shsh you can’t downgrade so can’t jailbreak either

hi folks
i hope you can help me. I am knew to this and have met the criteria and followed the guide above, which all seems very straight forward, however upon restarting “with my vodafone sim”, i have my phone saying “Different SIM detected, please connect to itunes”. Is this safe to do?

Hello everyone. I have a big perblom I have i4 jb through snow breeze, I had 4.3.2 but upgraded to 4.3.3 in hopes that it would solve the perblom but it did not.! I do not know if it is the right forum but here comes my question when I through installaous trying to DL either via FileApe I get a completely blank page forward and the connection is and run forever without anything coming out. If I choose FileDude comes 500 internal server error, the only place that works is zshare. Are there others who have experienced or have this perblom and does anyone know how my perblom solved

WORKS! 3GS 3.1.3(sn0wbreeze) 5.11.07

I found your manual patch instructions, then the Update link to this page with the blacksn0w RC2 info. Thank you IPHONEHEAT!

hannah June 3, 2010, 7:15 pm

I have tried this several times now, and every time I get to the end and my phone no longer has service (always “Searching”) or WiFi. When I reset network settings, the phone restarts and finds a network, but after a few seconds (10 at the longest) it goes back to “Searching”.

I have a 3G with 3.1.3 and 5.11.07. I have an activated SIM card (AT&T) but am trying to unlock as I am abroad for several months. I’m very new to all of this, but I’ve followed instructions carefully and can’t figure out what’s going wrong. I can’t find a solution anywhere… help please??

iPhoneHeat June 4, 2010, 2:46 pm

Hi, I have problem in my 3gs with baseband 05.11.07. After I unlock it with blacksn0w RC2, it is working fine but yesterday I am using net on the phone, first automatically its network go out and then it’s stuck and when I do the hard rest and when phone turn on it is only searching the network when I go to the setting to check about its version(In About) the phone goes stuck. But when I remove the blacksn0w RC2 from phone. Everything working fine. So plz send me the possible solution from where I can unlock my phone.

iPhoneHeat June 12, 2010, 3:49 pm

remobe BlackSn0w from Cydia and reinstall

Tahir June 14, 2010, 1:03 pm

Sir I already done this, remove and reinstall blacksn0w RC2, but all in vain. so plz give me some other solution if u can?

junks June 20, 2010, 1:14 am

Same for me. It was working originally, then after using Internet Tethering, it doesn’t work. I get:

Searching…
Can’t find Wifi signals, bluetooth unavailable

When I uninstall RC2, it works. When I reinstall, Searching…

iFony June 22, 2010, 6:52 pm

Any solution here???? The same problem on my phone, as soon as i install blacksn0w RC2 I get that “Searching Loop” and other freaky stuff is happening. I reinstalled and I even upgraded to iOS4 without upgrading BaseBand but still the same Issue.

kind regards

junks June 23, 2010, 10:54 pm

If RC2 isn’t working, uninstall it and use the NEW 100% working solution for ALL basebands ALL iphones 3.1.3 and lower: install ultrasn0w 0.93 from Source http://repo666.ultrasn0w.com.

I have it working now on my 3GS 3.1.3 5.11.07.

http://www.iphoneheat.com/2010/06/unlock-ios-4-0-05-13-04-baseband-with-ultrasn0w-0-93/

To jailbreak 4.0 with PwnageTool 4.01 (released June23) (and then use ultrasn0w to unlock) see if your device is supported at http://blog.iphone-dev.org/post/726179754/foursome-news (currently 3GS new bootrom not supported). Also, PwnageTool 4.01 is only available for Mac so you have to find a PwnageTooled.ipsw Can someone please post a link?

I can verify this method works. It was a pain in the butt trying to do all this manually so I have to give a huge thumbs up to the guys at PushFix for compiling this.

clintoris February 21, 2011, 11:07 am

Hi there, Been trying to jailbreak and unlock my old 3g all day now and have gotten all the way up to installing blacksn0w rc2. I have installed the pushfix.info source to cydia but I can’t find the blacksn0w rc2 under the search tab. Am I missing something, was I supposed to install something from the within the pushfix.info tab? I have os3.1.3 running created by pwnage and the baseband is 5.15.04.

Any ideas? please and thank-you!
