- Open iFaith and click OK
- Click ‘Show Available SHSH Caches on Server’
- Click YES when it asks you if you want to use your newly connected device
- Out of the 3 options shown, select ‘Show a list of available SHSH Blobs on TSS Server(s)’
- After a few moments (during which the blobs will be fetched), you will be shown this screen: Select the 6.1.3 blob from [Cydia] or [iFaith]
- Click ‘Download selected blob(s)’ and a prompt for a location to save the blob appears. Select one and click Ok. A dialog box pops up when the download is complete.

- Now, click on Browse for an IPSW. Choose the iOS 6.1.3 file.

- This new IPSW file will be saved on your computer. Note the name of the file. This is the file we’ll be using to downgrade.
C: The PWNED DFU Mode
You will now have to go into Pwned DFU mode to trick iTunes and install IPSW file on your iPhone 4. Here’s how to do that:
- With iFaith running and iPhone connected, switch off your iPhone 4.
- Put iPhone 4 in DFU mode (power+home button for a few seconds, release power and hold home button for 10-15 seconds)
- Open iTunes. Click on the device name (from the sidebar or on top-right).
- Hold down ‘Shift’ and click on Restore.
- Select the IPSW file that iFaith produced in the previous section.
- Once iTunes completes the restore, your iPhone 4 should be running iOS 6.1.3.
