Frequently asked questions

Will a hard reset delete everything on my Sony Ericsson C902?

Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the Sony Ericsson C902 to its out-of-box state. Back up anything you want to keep before starting.

Does resetting the Sony Ericsson C902 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 Ericsson C902?

Typically a few minutes, though it can take longer on older or heavily used devices as more stored data has to be wiped.

Does the Sony Ericsson C902 lock to an account after a reset?

Usually not — Factory Reset Protection (FRP) and Activation Lock are Android and iOS features. Most other platforms, including this device's, don't add an account lock after a reset.

Does my Sony Ericsson C902 have a hard reset button?

No — the Sony Ericsson C902 doesn't have a dedicated hard reset button or button combination. Use the Factory Reset method above instead.

What is recovery mode on my Sony Ericsson C902?

Recovery mode is a stripped-down menu outside the normal operating system, used to wipe data or apply updates when the Sony Ericsson C902 won't boot normally. See the Enter Recovery Mode section above for how to reach it on this device.

How do I reset my Sony Ericsson C902?

Use the Factory Reset method above — the Sony Ericsson C902 doesn't have a separate hardware hard-reset combination, so this is the method that applies.
