TinyUmbrella is a cool little software that you probably have heard of already. TinyUmbrella and this method are actually part of the 3194 error fix for “downgrading” your iOS firmware. But in some cases (like ours), it worked for an update too. It’s mostly because we had a jailbroken iPhone that wasn’t restored to factory settings. Here’s how it works:
Step 1 : Download the iOS firmware that you wish to upgrade/downgrade your iPhone to.
Step 2 : Download TinyUmbrella
Step 3 : Connect your iPhone and close iTunes if it pops open automatically.
Step 4 : Open TinyUmbrella and then click on ‘Start TSS Server’
Step 5 : Put your iPhone in DFU.
Step 6 : Now, if you are updating your firmware, you’ll have to click on Shift + Restore (Win) / Option + Restore (Mac) and point it to the iOS ipsw file you downloaded in step 1.
Hopefully, iTunes will restore it to the correct iOS firmware you pointed to and update your iPhone to it.
Note: If you wish to downgrade, you’ll need to save SHSH blobs either to your local drive or on Cydia. Right now, Cydia has saved SHSH blobs up to iOS 7.0.4; you’ll need to save the SHSH blobs of your device (and you can use TinyUmbrella for this).
If you can't get the update process to work even after changing your hosts file, you can try remotely erasing your iOS device using iCloud. The device you're trying to erase will need to have internet access and "Find My iPhone" enabled. You'll be able to restore the device from any iCloud or iTunes backup after erasing it.
Step 1 : Log into the iCloud website or open the "Find My iPhone" app on another device.
Step 2 : Open the Find My iPhone service in iCloud. This will open a map with your registered iOS devices.
Step 3 : Select your iOS device from the top menu. Click the "All Devices" menu and select the iOS device you want to restore.
Step 4 : Click the "Erase" button in the iOS device's card. After confirming, the iOS device will begin automatically resetting to factory settings. This may take a while to complete.
Step 5 : Setup your iOS device and restore your backup. Start the iOS device setup process as if it were a new phone. You'll be given the choice to choose a backup from iCloud or iTunes, or you can proceed with a fresh install.
