Frequently asked questions
Will a hard reset delete everything on my Sony Ericsson P900?
Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the Sony Ericsson P900 to its out-of-box state. Back up anything you want to keep before starting.
Does resetting the Sony Ericsson P900 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 P900?
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 P900 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.
What is recovery mode on my Sony Ericsson P900?
Recovery mode is a stripped-down menu outside the normal operating system, used to wipe data or apply updates when the Sony Ericsson P900 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 P900?
Use the Factory Reset method above — the Sony Ericsson P900 doesn't have a separate hardware hard-reset combination, so this is the method that applies.
How do I format my Sony Ericsson P900?
"Formatting" and "factory resetting" mean the same thing for the Sony Ericsson P900 — both erase all data and restore default settings. Use whichever method above matches your situation.
