Huawei Mate 40 Pro 4G — Hard Reset, Factory Reset & Recovery Mode Guide

🔧

Hard Reset via Recovery — Huawei Mate 40 Pro 4G

Optimized for Mate 40 Pro 4G (HarmonyOS 2.0)

⚠️ A hard reset erases ALL data (apps, photos, accounts). Back up first.
1
Huawei Mate 40 Pro 4G runs HarmonyOS 2.0. Early HarmonyOS releases (2.x) were built on the Android Open Source Project, so they generally kept a Volume+Power recovery combo similar to Android.
2
Try powering off the device, then holding Volume Up + Power until a recovery menu or Huawei logo with options appears.
3
If nothing happens after 10–15 seconds (more likely on HarmonyOS 3.0+/NEXT, which dropped the Android base), release the buttons and use the Factory Reset method below instead.
4
Huawei's newer native HarmonyOS builds don't publish a standard hardware combo — check Huawei's official support site for your exact model if you're stuck.
📱

Factory Reset from Settings — Huawei Mate 40 Pro 4G

Optimized for Mate 40 Pro 4G (HarmonyOS 2.0)

⚠️ Permanently deletes personal data. Make sure backups are saved.
1
Open Settings on your Huawei Mate 40 Pro 4G (running HarmonyOS 2.0).
2
Go to "System & updates" then "Reset".
3
Tap "Reset phone" (or "Erase all data" on older builds).
4
Confirm your PIN or password.
5
Tap "Reset" — your Huawei Mate 40 Pro 4G wipes and restarts.
🛠️

Enter Recovery Mode — Huawei Mate 40 Pro 4G

Optimized for Mate 40 Pro 4G (HarmonyOS 2.0)

✅ Safe to enter — this does not erase any data.
1
Huawei Mate 40 Pro 4G runs HarmonyOS 2.0. On HarmonyOS 2.x (Android-based) models, a recovery screen may be reachable similarly to Android: power off, then hold Volume Up + Power.
2
On newer native HarmonyOS (3.0+/NEXT) models, this screen may look different or not exist in the same form — Huawei's own eRecovery/HiSuite tools are the more reliable route for those.
3
If nothing appears within 10–15 seconds, restart normally instead and use the Factory Reset method above.
🔓

FRP / Account Lock Help — Huawei Mate 40 Pro 4G

Optimized for Mate 40 Pro 4G (HarmonyOS 2.0)

For legal owners only. Do not use on lost or stolen devices.
1
Huawei ID Lock is HarmonyOS's equivalent of Android's FRP — it ties the device to the last signed-in Huawei ID after a reset.
2
If locked out, sign in with the original Huawei ID on the setup screen, or verify ownership via cloud.huawei.com.
3
Contact Huawei Support with proof of purchase if you can't access the original account.

Why reset your Huawei Mate 40 Pro 4G?

A hard reset on the Huawei Mate 40 Pro 4G 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 Huawei Mate 40 Pro 4G?

Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the Huawei Mate 40 Pro 4G to its out-of-box state. Back up anything you want to keep before starting.

Does resetting the Huawei Mate 40 Pro 4G 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 Huawei Mate 40 Pro 4G?

Typically a few minutes, though it can take longer on older or heavily used devices as more stored data has to be wiped.

Will I need my Google account password after resetting the Huawei Mate 40 Pro 4G?

Yes, if Factory Reset Protection (FRP) is enabled. Android (and HarmonyOS 2.x devices with Google services) will ask for the last signed-in Google account after a reset — make sure you know that password first.

Can I factory reset my Huawei Mate 40 Pro 4G without the password?

Yes — resetting through recovery mode doesn't require your lock screen password, since it bypasses the login screen entirely. That said, Factory Reset Protection may still ask for your Google account credentials afterward as an anti-theft measure.

Does my Huawei Mate 40 Pro 4G have a hard reset button?

Not a single dedicated button — the Huawei Mate 40 Pro 4G uses a button combination instead of one labeled "reset." See the Hard Reset section above for the exact keys to press.

How do I reset my Huawei Mate 40 Pro 4G?

Use the Hard Reset method above if your Huawei Mate 40 Pro 4G 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.
