How to Factory Reset — Siemens SX66

⏱ ~5 min📋 5 steps

The Siemens SX66 is a 2004 Microsoft Windows Mobile 2003 SE PocketPC device with 128MB and 128MB internal storage. It features a 3.5", TFT resistive touchscreen, 65K colors, 240.0x320.0 display and is available in Silver.

The SX66 is equipped with a Removable Li-Ion battery. The device uses a Mini-SIM configuration. It weighs 210 g.

Factory Reset on the Siemens SX66 works differently than it does on Android, since this platform uses its own menus and terminology. Follow the steps below, written specifically for this device rather than adapted from Android instructions.

All personal data, accounts, and apps will be permanently removed.

1

Back up your data first — Windows Mobile resets erase everything

2

From the Today screen, go to Start > Settings > System > Clear Storage

3

Enter the confirmation code, commonly 1234 by default

4

Tap 'Yes' to confirm — the device restarts and reinstalls its default configuration

5

On older stylus models, a physical reset pinhole near the battery only performs a soft restart, not a data wipe
