Thread: Solve Unlocking problem on iPhone 3Gs when network is unavailable

Problem:
Choosing file "iPhone2,1_5.0.1_9A405_Restore" and doing the jailbreak by "redsn0w_win_0.9.10b3"
but now the network is unavailable and the life battery being too short

Solution:
First of all Things you need to download:
1. [Only registered and activated users can see links. ] (If you are on Windows) or [Only registered and activated users can see links. ] (If you are on Mac)
2. [Only registered and activated users can see links. ]
3. Search iFile on Cydia and download it on your iPhone. iFile costs $4.00 but if you can't buy it, you can get it for free by adding source: [Only registered and activated users can see links. ]. If you don't know how to add source in Cydia, [Only registered and activated users can see links. ]. Once you add the source, search for iFile in cydia and download it.
We are now done with the downloading stuff. Connect your iPhone with computer and run iFunbox.

From the left pane, select your iPhone and go to Raw File System/System/Library/Frameworks/CoreTelephony.framework/Support/


Make a backup of the file CommCenterClassic and then delete the file. Now copy the CommCenterClassic file you downloaded in the step two and paste it in the same folder i,e Raw File System/System/Library/Frameworks/CoreTelephony.framework/Support/

Close ifunbox.

Here is the video [Only registered and activated users can see links. ]

Now open iFile on your iPhone and navigate to System/Library/Frameworks/CoreTelephony.framework/Support/

Tap on the blue arrow next to CommCenterClassic, navigate below until you see Access Permissions heading.

[Only registered and activated users can see links. ]


Now set User, Group and World/Global as


User: Read, Write, Execute
Group: Read, Execute
World/Global: Read, Execute

Once you are done, close iFile and install ultrasn0w from Cydia and then insert your sim card followed by restarting your iPhone. Since you are [Only registered and activated users can see links. ] on iOs 5.0.1, you need to boot tethered using Redsn0w or iBooty to boot your iPhone.

Once your iPhone reboots, you will have unlocked iPhone 3GS.If this solution helpled you than please press thanks it would be apreciated.
