This method is faster and is less complicated

• Check Firmware version.
  • Unactivated phones

-Drag slider to the right to make an emergency call.
-Dial *3001#12345#* then press call
-Select Version
 
If firmware (this is not a typo) is 03.12 then firmware is either 1.0 or 1.01. You need to upgrade this to 1.02.
 
If you see 03.14 then you have 1.02 already, you are lucky
If you see 04.01 then you have 1.1.1. A little more patience is needed

• Activated phones (locked and not jailbroken)

- Go to Settings -> About to check your baseband and firmware version.

• What you need:

Software:
iTunes version 7.4.1.2 (I use this and never had problems) 7.5setup tested also
ibrickr versions 0.8 and 0.91 (You will know why later)
putty
SWUnlockiPhone-klip (This contains PACAY by brasuco for easy Activation and unlock.pxl)
baseband-flash + secpack (You will see secpack****.bin in the folder. Just rename it to secpack)
Installer-2.63.pxl (sometimes browsing applications in ibrickr times out so I used this instead)
Google for all of these. I do not take credit for these apps. They are not mine but they can easily be found all over the internet.
 
Hardware:
iPhone dock connect to PC via USB
WIFI needed for v1.1.1 only
and iPhone of course

• Downgrading firmware

Turn off the iphone, open itunes and device manager (make sure this is on top). Collapse the USB Controllers part so you can see clearly the driver installed.
 
[FONT="][/FONT]
 
 
Dock your iphone. Once you see the gray apple, hold the power and home keys until the screen shuts off. Release the power button after 1 second but keep holding the home button until you see Apple’s DFU driver installed or at least windows says installing new driver.
 
Go to iTunes and you will see that the phone was detected in recovery mode. Hold the shift key then click restore and select the file I highlighted and wait for the restore to finish.
 

 
Once it’s done itunes will show you an error but it’s ok. You should either see the regular activate screen or the yellow connect to itunes triangle. If you see the USB cable with iTunes logo, try it again. If you get the yellow triangle, open ibrickr v 0.91 and click begin downgrade to 1.02 then select the middle option and you’re phone should boot back on the activate screen.

• Jailbreaking (I have always used v 0.8 for this method)

Click on free my iphone then once ibrickr is ready, turn off your phone. Take it out of the dock, place it back while holding the home key, let go once you see the yellow triangle again. Just wait for ibrick to finish. Close ibrickr and open it again once you see the activate screen.
 
Now click on applications and follow the instructions there. You should see this screen when it’s done.
 

 
 
Click on Install from PXL file and install unlock.pxl (and Installer-2.63.pxl if you started with v 1.1.1)
 
With ibrickr still open, run (CLICK HERE) activate.bat found in the PACAY folder and wait for it to finish then restart your phone. Go to settings-> general-> Auto Lock and set it to never.
 

 
Go back to ibrickr’s main screen and click on Files. You will see an iphone on the right side of the screen with directories. Go to usr->bin and upload these files (extracted from baseband-flash):
 

 
 
Note: Once baseband flash is extracted you will secpack41103.bin (not sure of the filename anymore) just rename this to secpack.
 
Connect to Wifi then run Installer. Install these in the specific order:
Community sources
BSD subsystem
Open SSH
 
Once it’s all done go back to settings -> WIFI. Tap the blue arrow beside your connection to check your IP.
 
Open putty and plug in the IP address in the box.
 

 
 
A terminal will now open. Username is root and password is dottie.
Now type each command line and press enter… and yes it is case sensitive so make sure to follow the capitalizations. My comments will start with ***
 
cd /usr/bin
chmod +x bbupdater
chmod +x ieraser
launchctl remove com.apple.CommCenter
bbupdater –v *** checking baseband is 4.01
ieraser *** this will erase the baseband
bbuppdater –e *.eep –f *.fls
bbupdater –v *** Checking if baseband is downgraded to 3.14
launchctl load /System/Library/LaunchDaemons/com.apple.CommCenter.plist
exit

• Run Unlock found on your main screen and wait for it to finish. Once it’s done, just insert a non ATT/Cingular SIM and make a test call. Check youtube connection as well.
