Why reset your Sendo S300?

A hard reset on the Sendo S300 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 Sendo S300?

Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the Sendo S300 to its out-of-box state. Back up anything you want to keep before starting.

Does resetting the Sendo S300 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 Sendo S300?

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 Sendo S300 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 Sendo S300?

Use the Factory Reset method above — the Sendo S300 doesn't have a separate hardware hard-reset combination, so this is the method that applies.

How do I format my Sendo S300?

"Formatting" and "factory resetting" mean the same thing for the Sendo S300 — both erase all data and restore default settings. Use whichever method above matches your situation.

Does my Sendo S300 have a hard reset button?

No — the Sendo S300 doesn't have a dedicated hard reset button or button combination. Use the Factory Reset method above instead.
