Samsung i550 — Hard Reset, Factory Reset & Recovery Mode Guide

🔧

Hard Reset via Recovery — Samsung i550

Optimized for i550 (Symbian OS 9.2, Series 60 v3.1 UI)

⚠️ A hard reset erases ALL data (apps, photos, accounts). Back up first.
1
Samsung i550 runs Symbian OS 9.2, Series 60 v3.1 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 i550

Optimized for i550 (Symbian OS 9.2, Series 60 v3.1 UI)

⚠️ Permanently deletes personal data. Make sure backups are saved.
1
Open the Settings/Tools menu on your Samsung i550 (running Symbian OS 9.2, Series 60 v3.1 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 i550

Optimized for i550 (Symbian OS 9.2, Series 60 v3.1 UI)

✅ Safe to enter — this does not erase any data.
1
There's no standardized "recovery mode" screen on Symbian OS 9.2, Series 60 v3.1 UI the way there is on Android or iOS.
2
Restarting or soft-resetting your Samsung i550 (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.

3
If your Samsung i550 does prompt for a security code after reset, check Samsung's support site for their specific unlock process.

Why reset your Samsung i550?

A hard reset on the Samsung i550 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 i550?

Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the Samsung i550 to its out-of-box state. Back up anything you want to keep before starting.

Does resetting the Samsung i550 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 i550?

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 i550 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 Samsung i550 have a hard reset button?

Not a single dedicated button — the Samsung i550 uses a button combination instead of one labeled "reset." See the Hard Reset section above for the exact keys to press.

Can I factory reset my Samsung i550 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 Samsung i550?

"Formatting" and "factory resetting" mean the same thing for the Samsung i550 — both erase all data and restore default settings. Use whichever method above matches your situation.
