Frequently asked questions
Will a hard reset delete everything on my Sony Ericsson P990?
Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the Sony Ericsson P990 to its out-of-box state. Back up anything you want to keep before starting.
Does resetting the Sony Ericsson P990 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 P990?
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 P990 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 P990 have a hard reset button?
No — the Sony Ericsson P990 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 P990?
Recovery mode is a stripped-down menu outside the normal operating system, used to wipe data or apply updates when the Sony Ericsson P990 won't boot normally. See the Enter Recovery Mode section above for how to reach it on this device.
Can I factory reset my Sony Ericsson P990 without the password?
Yes — the reset methods above don't require your lock screen password, since they bypass the normal login screen entirely.
