2
Press and hold: Call + End + Reset Pinhole.
3
Keep holding all keys together until the screen shows a formatting screen, progress animation, or the device restarts on its own.
4
This formats the internal storage and erases all user data — contacts, messages, apps, and settings — returning Samsung D900i to factory condition. It works even if the phone is completely frozen or stuck on the logo screen, since it happens before the operating system loads.

Frequently asked questions

Will a hard reset delete everything on my Samsung D900i?

Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the Samsung D900i to its out-of-box state. Back up anything you want to keep before starting.

Does resetting the Samsung D900i 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 Samsung D900i?

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 Samsung D900i 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.

How do I reset my Samsung D900i?

Use the Hard Reset method above if your Samsung D900i 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.

How do I format my Samsung D900i?

"Formatting" and "factory resetting" mean the same thing for the Samsung D900i — both erase all data and restore default settings. Use whichever method above matches your situation.

Can I factory reset my Samsung D900i without the password?

Yes — the reset methods above don't require your lock screen password, since they bypass the normal login screen entirely.
