A tool to downgrade iOS 8.1.3 / 7.1.2 to iOS 6.1.3 / 6.1.4 / 6.1.6 / 8.1.2 / - without SHSH and AP tickets - A5+

how to install ios 6 on iphone 4Apple never allows you to downgrade iOS on iDevices, that's the major problem faced by many users as we know that latest version of iOS is not the greatest as it slows down old devices and also destroys jailbreak. iPhone 4 became almost unusable after iOS 7 update and iPhone 5 and 4S faced noticeable lags which are very annoying. We all know that iOS 6 and      iOS 5 were lightning fast but apple don't want us to be happy.

But don't worry you can downgrade to previous version of iOS without even need of SHSH Blobs and AP Tickets.
IPSW tool generates ECID-SHSH blobs using UDID and ECID info fetched from the device and generates a patched .ipsw which
fakes the firmware verification process and
restores your device to previous baseband. iPhone 4 users can now downgrade their device to iOS 6.1.3 or 5.1.1 WITHOUT SHSH BLOBS.

Usins IPSW Tool you can downgrade the following devices without shsh blobs:

[A4]iPhone 4: [iOS 7.1.2 to 6.1.3] [iOS 7.1.2 to 5.1.1]
[A5]iPhone 4S: [iOS 8.1.3 to 8.1.2] [iOS 8.1.3/8.1.2 to 6.1.3] [iOS 8.1.3 to 5.1.1]
[A6]iPhone 5: [iOS 8.1.3 to 8.1.2] [iOS 8.1.3/8.1.2 to 6.1.4]
[A7]iPhone 5S: [iOS 8.1.3 to 8.1.2]
[A7]iPhone 5C: [iOS 8.1.3 to 8.1.2]
[A8]iPhone 6: [iOS 8.1.3 to 8.1.2]
[A8]iPhone 6+: [iOS 8.1.3 to 8.1.2]

[Also applies to same corresponding iPod and iPad Chip. ]

iPSW tool supports Apple A4, A5, A6, A7 and A8 devices, however you cannot downgrade to any version of iOS 6 on A7 devices but still you can switch to any version of iOS 7 on these devices.

[UPDATE: 12/11/14]
Note: A8 Devices ie: iPhone 6, iPhone 6 Plus, iPad Air 2 only supports iOS 8 downgrades due to it's baseband version.

Here is how:

Connect your A4, A5, A6, A7 or A8 device and start iPSW tool.
Make sure you are connected to internet.

Note: Please make backup of your device before proceeding to restore process.

Now simply put your device in DFU mode and start itunes, restore the patched .ipsw by clicking on restore (holding shift key) and it will start installing iOS firmware without any errors.
Note: If your restore stuck with itunes error_xxxx then check your host file, make sure it does not contain any bad host entry which usually blocks the restore.

After restoring firmware, your device will take a while to boot for repairing disk permissions and installing kernel cache.

[Update 02/08/15]
Some users reported that restore is not working in new version of iTunes 12.x.x and later.
[Fix]
Make backup of these files 
MobileDevice.dll
iTunesMobileDevice.dll
AppleMobileDeviceService_main.dll  in
C:\Program Files (x86)\Common Files\Apple\Mobile Device Support  [64bit Users]
C:\Program Files\Common Files\Apple\Mobile Device Support  [32bit Users]
and replace them with these files. After replacing these files, patch your firmware with iPSW tool and restore it with iTunes without the error: 200x.
Note: This update applies only if you are downgrading to iOS 5.1.1 and 6.1.3/4
