Can I Downgrade iPhone 5c (Global)?
iPhone 5c (Global)
iPhone5,4
Downgrade is Currently Not Supported
Apple is currently only signing iOS 10.3.3 for iPhone 5c (Global). The signing window for iOS 10.3.2 and all earlier releases has closed.
Apple permanently closes the signing window for older releases within 1 to 2 weeks of launching a newer update. Because Apple's servers authenticate each restore online, trying to install any previous iOS build on iPhone 5c (Global) will immediately fail with iTunes Error 3194.

Can I downgrade from an iOS Beta on iPhone 5c (Global)?
Yes. If your iPhone 5c (Global) is running an iOS Beta, you can always restore back to the latest signed public release using Recovery Mode in Finder (Mac) or iTunes / Apple Devices (Windows).
Can I downgrade to the iOS version iPhone 5c (Global) originally shipped with?
No. Apple permanently closes the signing window for older releases. Even though iPhone 5c (Global) originally launched with an earlier version, Apple servers will no longer authenticate that installation.
What can I do if I cannot downgrade iPhone 5c (Global) but experience battery or performance bugs?
You can perform a clean restore to the latest signed firmware using a computer to eliminate software glitches and corrupted cache, or await the next minor point update from Apple that includes targeted bug fixes.
Can I downgrade iPhone 5c (Global) if the signing window has closed?
No. Apple servers reject restore verifications for unsigned builds (returning iTunes Error 3194). Unsigned firmware cannot be installed on standard Apple devices.
Will restoring or downgrading iPhone 5c (Global) erase data?
Yes. Flashing an IPSW firmware file requires a restore that wipes on-device storage. Ensure your personal data is backed up to iCloud before proceeding.
