Frequently asked questions
Will a hard reset delete everything on my Sony Xperia C5 Ultra?
Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the Sony Xperia C5 Ultra to its out-of-box state. Back up anything you want to keep before starting.
Does resetting the Sony Xperia C5 Ultra remove the SIM lock or carrier lock?
No. A hard or factory reset only clears data and settings — it doesn't remove a carrier/SIM lock, which is tied to the device's IMEI at the network level. You'd need to contact your carrier for an unlock.
How long does a factory reset take on the Sony Xperia C5 Ultra?
Typically a few minutes, though it can take longer on older or heavily used devices as more stored data has to be wiped.
Will I need my Google account password after resetting the Sony Xperia C5 Ultra?
Yes, if Factory Reset Protection (FRP) is enabled. Android (and HarmonyOS 2.x devices with Google services) will ask for the last signed-in Google account after a reset — make sure you know that password first.
Does my Sony Xperia C5 Ultra have a hard reset button?
Not a single dedicated button — the Sony Xperia C5 Ultra uses a button combination instead of one labeled "reset." See the Hard Reset section above for the exact keys to press.
Can I factory reset my Sony Xperia C5 Ultra without the password?
Yes — resetting through recovery mode doesn't require your lock screen password, since it bypasses the login screen entirely. That said, Factory Reset Protection may still ask for your Google account credentials afterward as an anti-theft measure.
How do I reset my Sony Xperia C5 Ultra?
Use the Hard Reset method above if your Sony Xperia C5 Ultra is frozen or won't respond, or the Factory Reset method if the screen still works normally — both are covered step by step on this page.
