Nokia 3660 — Hard Reset, Factory Reset & Recovery Mode Guide

🔧

Hard Reset via Recovery — Nokia 3660

Optimized for 3660 (Symbian 6.1, Series 60 v1.0 UI)

⚠️ A hard reset erases ALL data (apps, photos, accounts). Back up first.
1
Turn Nokia 3660 off completely — remove and reinsert the battery first if it's frozen or unresponsive.
2
Press and hold: Call (Green) + * + 3 + Power.
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 Nokia 3660 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.
5
Note: Key combo works if device gets stuck on Nokia boot logo.
📱

Factory Reset from Settings — Nokia 3660

Optimized for 3660 (Symbian 6.1, Series 60 v1.0 UI)

⚠️ Permanently deletes personal data. Make sure backups are saved.
1
From the home screen, dial *#7370# on the keypad.
2
Enter the security code when prompted — the default is 12345 unless it's been changed.
3
Confirm to proceed. This erases all user data — contacts, messages, apps, and settings — and restores Nokia 3660 to factory condition.
🛠️

Enter Recovery Mode — Nokia 3660

Optimized for 3660 (Symbian 6.1, Series 60 v1.0 UI)

✅ Safe to enter — this does not erase any data.
1
There's no standardized "recovery mode" screen on Symbian 6.1, Series 60 v1.0 UI the way there is on Android or iOS.
2
Restarting or soft-resetting your Nokia 3660 (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.

Why reset your Nokia 3660?

A hard reset on the Nokia 3660 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 Nokia 3660?

Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the Nokia 3660 to its out-of-box state. Back up anything you want to keep before starting.

Does resetting the Nokia 3660 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 Nokia 3660?

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 Nokia 3660 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 Nokia 3660?

Use the Hard Reset method above if your Nokia 3660 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.

Can I factory reset my Nokia 3660 without the password?

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

How do I format my Nokia 3660?

"Formatting" and "factory resetting" mean the same thing for the Nokia 3660 — both erase all data and restore default settings. Use whichever method above matches your situation.
