How To Put Your iPhone into DFU Mode?

What is the difference between Restore and recovery Mode?

Recovery Mode : Recovery Mode is a state of iBoot that is used during standard upgrades and restores. As iBoot is active, it does not allow you to downgrade your device’s software. Also, unless it is ‘pwned,’ it will not allow custom firmware to be flashed.

DFU Mode : DFU Mode is a special mode where the device can still interface with iTunes, yet it does not load the iBoot. The screen will appear totally black in DFU mode, so you can’t guess whether the device is in DFU or powered down from simply looking at the screen. Because iBoot and the OS are not loaded this exploit makes us able to downgrade your iPhone firmware or upgrade with a custom firmware created by Pwnage tool.

How to put your iPhone in recovery mode :

Turn the device completely off and disconnect it from cable/dock.
Hold down the home button.
While holding down the HOME button connect to a computer with a cable (easiest) or dock.
Keep holding down the home button until you see a connect-to-itunes screen You are now in recovery mode.

To escape Recovery Mode and power the phone off simply hold down power and home buttons for ten seconds.

How to put your iPhone in DFU mode :

Connect your iPhone to your computer.
Turn iPhone off.
Hold power and home together for 10 seconds (exactly).
Release power but keep holding home until the computers beeps (observed on a PC) as a USB device is recognized.
A few seconds later iTunes should detect your iPhone.
If the Restore Logo is present on the screen, you are in Recovery Mode, not DFU.

DFU means Device Firmware Update. If a restore using Recovery Mode doesn't work you will want to use DFU Mode as a last resort. When placing your iPhone into DFU Mode it does not load the OS before attempting the restore

To put the iPhone into DFU mode so you can do an iTunes firmware restore follow these steps: Step One
Open iTunes and connect the iPhone to your Mac.

Step Two
Press and hold the Home button and the Sleep/Wake button at the same time.

Step Three
After exactly 10 seconds release the Sleep/Wake button. Continue holding the home button until you iTunes pops up a message telling you that it has detected an iPhone in recovery mode.

The iPhone screen will remain black like this:

NOTE***: It may take a few attempts to get your iPhone into DFU mode. Generally, I hold down both buttons then release the Home button just before I think the Apple logo would appear. If you are still holding both buttons down and you see the Apple logo you are holding them down for too long!

3GS Owners - Can I Upgrade and Jailbreak to iOS 4.0?

You are NOT able to Jailbreak iOS 4 IF you have anyone of the following criteria:-
1 - You have already upgraded to iOS 4 using the iTunes upgrade or restore process. Meaning you have upgraded to iOS 4 without using a customized iOS 4 ipsw using Pwnage Tool for Mac (for example)

2 - Your 3GS is Jailbroken using Spirit previously. If you are this stage, you need to wait for Geohot to release the new Spirit for iOS 4.

3 - The 3GS have the NEW Bootrom. Regardless whether you have already jailbreak or not, there is NO solution for the new Bootrom 3GS. Need to wait for any hackers to release a new Jailbreak.

As mentioned by the Dev-Team:

iPhone 3GS

Summary: Currently, PwnageTool only works on previously jailbroken 3GS devices with the old bootrom.

If you have a Jailbroken iPhone 3GS with the OLD BOOTROM and you DID NOT use Spirit to jailbreak then you can create the ipsw with PwnageTool 4.0 and restore with your jailbroken recovery mode.
If you have an iPhone 3GS with the NEW BOOTROM this is NOT supported by PwnageTool 4.0 PwnageTool 4.01

How To: Check iPhone 3GS New Bootrom or Old Bootrom (iBoot) Version

Courtesy of By Taimur Asad | June 25th, 2010

On Mac OS X

Step 1: Put your iPhone into DFU Mode (not recovery mode)

Connect your iPhone to your computer.
Turn iPhone off.
Start iTunes.
Hold Power and Home buttons together for 10 seconds or so.
Release Power button but keep holding the Home button until your computer recognizes a new USB device.
iTunes will now recognize your iPhone.

Note: Your iPhone screen at this time should be blank (black in color), if not, then you are most likely in Recovery Mode, not DFU mode.

Step 2: Run "System Profiler" and navigate to: Hardware -> USB (menu on left).

Step 3: At the top right under “USB Device Tree” panel click “Apple Mobile Device (DFU Mode)”.

Step 4: Now down under in “Serial Number”, simply go through the string and you’ll find the bootrom version (iBoot) as shown in the screenshots below:

iPhone 3GS – Old Bootrom 359.3

Step 5: If it’s 359.3, you have old bootrom. If it’s 359.3.2 or anything above that, its a new bootrom.

Note: In both the cases above, it doesn’t matter whether your iPhone is an MB model or an MC model. As long as it has 359.3 bootrom, it is iPhone 3GS with old bootrom, and if 359.3.2 or above then it is iPhone 3GS with new bootrom.

Internet Sharing from Macbook Pro to iPad

Today, I tried several experiments to see which works.

Internet <---> Ethernet <---> MBP <---> WiFi (Airport enabled) <---> iPad (THIS WORKS)

Internet <---> iPhone 3GS <---> USB <---> MBP <---> WiFi <---> iPad (WORKS)

Review - My Yoobao iPad Case

I have been searching high and low for the best iPad case.
Finally I decided to get Yoobao V2 from eBay. The seller seems genuine enough.
I have never purchased anything from eBay, but my previous and first experience in getting an STM XS Scout iPad Bag from Amazon encourage me to buy from online again.
The Yoobao iPad Case which I ordered from eBay arrived today (almost 10 days).
