Steps to retrieve iphone 4 and 3GS's Passwords using 3uTools

Please note that this tutorial is only for iPhone 4 and 3GS, which run on the system versions lower than iOS7.0, with 4-bit passwords!
If you change a new password and then forget it suddenly, it would be a little hard for you to deal with it. iOS Restoring could remove your data. However, the 3uTools can’t only jailbreak and flash iOS devices, but also provide a variety of useful advanced features, for example, retrieving the device’s password. You can tap “Jailbreak→Advanced” to find it. But the tool can only support the iPhone3GS and iPhone 4 running the system lower than iOS7.0 and then retrieve the 4-bit passwords. Anyway, please do what 3uTools reminds.
Step 1. Please connect your iPhone to the computer via original Apple USB cable, and then start 3uTools.
Step 2. Please ensure your iPhone in DFU Mode. As to the steps to enter into the DFU mode, you can do according to the tool’s reminders. Then Tap Flash Jailbreak→Advanced→Retrieve device’s password.
Step 3. During the password reading process, the white data rolls over on your iPhone device screen.
Step 4. Keep waiting instead of making other operations before the password reading process is completed. Finally, we get the password:1234
We have preset a very simple password for this tutorial, and thus it takes about 8 minutes to finish the process. As to the iPhone with a more complex password,  it will take more time. So, be patient if you preset a complex one!
And then after you need to restart your iPhone by pressing the Home button and Power button simultaneously for 10 seconds.
FAQ about 3uTools retrieving iPhone’s password:

  1. Why the original Apple USB cable?

Try your best to use the original Apple USB cable in order to ensure the successful match of input impedance, and thus the transmission of data is not influenced by the physical connection.

  1. Why the only iPhone 3GS and 4 get such support? What about iPhone 4S, 5,…?

Currently, the tool’s feature of retrieving the device’s password can only support the iPhone 3GS and 4 running the system versions lower than iOS 7.0, and at the same time, 3uTools can only read 4-bit passwords! In addition, this feature will become the invalid if both devices are upgraded to iOS7.0 or higher iOS versions. Actually, the iPhone 4S, 5 and other above iOS devices have different CPU architectures.

  1. Why can the tool only support 4-bit password reading?

The 3uTools try various different password combinations until one of them succeeds. As to 4-bit password, there are tens of thousands of number combinations (from 0000 to 9999). So it has been a very complex task for the software to work out the correct password. Sometimes, you will need to spend half an hour or more in order to retrieve a complex 4-bit password. By the way, please don’t do other various operations, for example, deleting any system file, when you forget the password, but use the 3uTools to help you retrieve it.
