It is also possible to downgrade an [[iPad 2]] to 5.x with 4.x and 5.x SHSH or 4.x with only 4.x SHSH blobs. iPhone 4s and iPad 2 downgrading will require [[redsn0w]]. [[Odysseus]] can be used on some devices to downgrade to certain iOS versions providing the user has SHSH blobs and the device is jailbroken. OdysseusOTA can be used to downgrade an iPhone 4s or iPad 2 to 6.1.3 from any firmware providing the device is jailbroken even without SHSH blobs due to Apple not closing the signing of 6.1.3 OTA's for those devices.</div></td>

This means you can use another person's SHSH blobs. For example, GeekGrade is iFaith IPSWs with prevent sleep preinstalled in them or a modified [[ramdisk]]. (Keep in mind this was done with iH8sn0w's work and also violates Apple's copyright by redistributing their iOS.) Also, to fix the dead LCD and DFU loop, you can use xpwntool to disable the flashing of a new iOS bootchain.</div></td>

Therefore a downgraded device with invalid SHSH blobs can boot into iOS without issues. For devices with just the blobs signed without [[ramdisk]] modification, you will need to select your IPSW in redsn0w and then select "Recovery fix". Afterwards, you can use the tether boot option. For the ones with a modified [[ramdisk]], you can simply select the stock IPSW needed for that iOS version and then tether boot. Using these methods, your device will boot into iOS. For an iOS 7 tethered downgrade, you require [[opensn0w]] to boot the device.</div></td>
