Why reset your Acer M900?

A hard reset on the Acer M900 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 Acer M900?

Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the Acer M900 to its out-of-box state. Back up anything you want to keep before starting.

Does resetting the Acer M900 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 Acer M900?

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 Acer M900 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 Acer M900?

Use the Factory Reset method above — the Acer M900 doesn't have a separate hardware hard-reset combination, so this is the method that applies.

How do I format my Acer M900?

"Formatting" and "factory resetting" mean the same thing for the Acer M900 — both erase all data and restore default settings. Use whichever method above matches your situation.

What is recovery mode on my Acer M900?

Recovery mode is a stripped-down menu outside the normal operating system, used to wipe data or apply updates when the Acer M900 won't boot normally. See the Enter Recovery Mode section above for how to reach it on this device.
