Samsung D720 — Hard Reset, Factory Reset & Recovery Mode Guide

🔧

Hard Reset via Recovery — Samsung D720

Optimized for D720 (Symbian OS 7.0, Series 60 UI)

⚠️ A hard reset erases ALL data (apps, photos, accounts). Back up first.
1
Samsung D720 runs Symbian OS 7.0, Series 60 UI, which resets through a dial code rather than a button combo.
2
From the home screen, dial *#7370# and confirm.
3
Enter the phone lock code when prompted — the default on most Symbian phones is 12345 unless you changed it.
4
The device restarts and wipes user data, similar to a factory reset.
5
If *#7370# doesn't work on your specific model, use the in-menu Factory Reset method below instead.
6
Alternative for this model: open the Phone app and dial *2767*3855# — ⚠️ this triggers an instant master reset with no confirmation screen, so only use it if you're certain you want to erase everything right now.
📱

Factory Reset from Settings — Samsung D720

Optimized for D720 (Symbian OS 7.0, Series 60 UI)

⚠️ Permanently deletes personal data. Make sure backups are saved.
1
Open the Settings/Tools menu on your Samsung D720 (running Symbian OS 7.0, Series 60 UI).
2
Look for "Restore factory settings" (naming varies: S60 devices often list it under Settings > General > Restore Factory Settings).
3
Choose "Delete all" if you want a full data wipe rather than just settings.
4
Enter your security code when prompted (default is 12345 unless changed).
5
Confirm — the device restarts with a clean setup.
🛠️

Enter Recovery Mode — Samsung D720

Optimized for D720 (Symbian OS 7.0, Series 60 UI)

✅ Safe to enter — this does not erase any data.
1
There's no standardized "recovery mode" screen on Symbian OS 7.0, Series 60 UI the way there is on Android or iOS.
2
Restarting or soft-resetting your Samsung D720 (hold Power for 10+ seconds, or use the reset pinhole if your model has one) is the closest safe equivalent.
3
For persistent issues, use the Factory Reset method above instead.
🔒

Lock Screen / Reset Notes — Samsung D720

Optimized for D720 (Symbian OS 7.0, Series 60 UI)

For legal owners only. Do not use on lost or stolen devices.
1
Factory Reset Protection (FRP) is a Google/Android security feature and doesn't apply to Samsung D720 (Symbian OS 7.0, Series 60 UI).
2
Most non-Android platforms don't lock the device to an account after a reset.
3
If your Samsung D720 does prompt for a security code after reset, check Samsung's support site for their specific unlock process.

Why reset your Samsung D720?

A hard reset on the Samsung D720 fixes boot loops, forgotten PINs and persistent lag. The method above will wipe the device back to factory condition. Always back up your data first, as a reset cannot be undone.

Frequently asked questions

Will a hard reset delete everything on my Samsung D720?

Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the Samsung D720 to its out-of-box state. Back up anything you want to keep before starting.

Does resetting the Samsung D720 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 D720?

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 D720 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 Samsung D720?

Recovery mode is a stripped-down menu outside the normal operating system, used to wipe data or apply updates when the Samsung D720 won't boot normally. See the Enter Recovery Mode section above for how to reach it on this device.

Does my Samsung D720 have a hard reset button?

Not a single dedicated button — the Samsung D720 uses a button combination instead of one labeled "reset." See the Hard Reset section above for the exact keys to press.

How do I reset my Samsung D720?

Use the Hard Reset method above if your Samsung D720 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.
