If the watch screen is broken or locked, use the app.
Smartwatches for kids are a modern parenting miracle. They offer peace of mind through GPS tracking, two-way calling, and SOS alerts. The Mibro Kids Z3 is one of the most popular models on the market due to its robust features and kid-friendly design. However, even the best technology can run into problems.
Is your Mibro Kids Z3 freezing frequently? Is it refusing to pair with the Mibro Fit app? Perhaps you are handing the watch down to a sibling, or you simply forgot the unlock password. In all these scenarios, a factory reset (also known as a hard reset or master reset) is the ultimate solution.
But here is the catch: Doing it the wrong way can turn your child’s smartwatch into an expensive plastic brick. That is why you need the best method.
In this guide, we will walk you through how to factory reset Mibro Kids Z3 using three distinct methods. We will also cover what to do before you reset, how to avoid common errors, and the exact steps to set the watch up again afterward.
Use this method if you cannot access the settings menu or if the watch is malfunctioning.
If the watch asks for a password after reset and you never set one, try 0000 or 1234. If that doesn’t work, contact Mibro support – the password may be tied to the previous owner’s account.

Before diving into the "how," it’s important to understand when a reset is necessary. A factory reset returns the device to its original out-of-the-box state. Fixing Bugs: If the watch is lagging or apps are crashing.
Unbinding the Watch: If you need to connect the watch to a new administrator's phone.
Privacy: To delete all photos, chat history, and GPS logs before giving it away.
Forgotten Passwords: If the screen lock is preventing access.
Method 1: The Best & Easiest Way (via Mibro Fit / Mibro Kids App)
For most users, the "best" method is using the companion app on the parent's smartphone. This ensures the device is properly unbound from your account, allowing a new user to register it later.
Open the App: Launch the Mibro Kids app on the primary administrator’s smartphone.
Select the Device: Ensure the Z3 is the active device in your profile.
Go to Settings: Tap on the "Watch Settings" or "Device Info" section. If the watch screen is broken or locked, use the app
Find the Reset Option: Look for "Factory Data Reset" or "Restore Factory Settings."
Confirm: You may be asked to enter your app password. Once confirmed, the watch will receive a signal and begin the wiping process automatically. Method 2: Resetting Directly from the Watch Face
If you have the watch in hand and it is functioning correctly, you can do it right from the wrist.
Wake the Watch: Press the side button to light up the screen.
Access Settings: Swipe through the menu until you find the Settings icon (the gear symbol).
Find Backup & Reset: Scroll down to the bottom of the settings list. Execute Reset: Tap "Restore Factory Settings."
Wait: The watch will display a loading screen, restart, and eventually show the initial QR code for pairing. Method 3: The "Hard Reset" (When the Screen is Frozen)
If the touch screen isn't responding or the watch is stuck in a boot loop, you may need a hardware-level reset.
Long Press: Hold down the side power button for at least 15–20 seconds. Force Reboot: The watch should vibrate and force a restart. Use this method if you cannot access the
Note: Unlike some Android devices, Mibro watches rarely have a physical "pinhole" reset button. If a long press doesn't work and the screen is locked, you must use the App Unbinding method mentioned in Method 1 to force a wipe once it regains a signal. Important Things to Remember
Backup Photos: A factory reset deletes all photos taken with the Z3's dual cameras. Be sure to save any precious memories to the app before resetting.
Battery Life: Ensure the watch has at least 50% battery before starting a reset. If the watch dies during a firmware wipe, it could "brick" the device.
SIM Card: You do not need to remove the SIM card to reset the software, but if you are selling the watch, always remove the SIM to protect your data plan and phone number. Troubleshooting: "Watch is still bound to another account"
This is the most common issue. If you bought a used Mibro Z3 and it says it's already bound, a factory reset on the watch itself will not fix this. For security reasons, the original owner must "Unbind" the watch from their Mibro Kids app. If you cannot contact the seller, you will need to reach out to Mibro Support with proof of purchase to have the IMEI released.
The best way to factory reset your Mibro Kids Z3 is through the Mibro Kids app. It’s the cleanest method to ensure the watch is ready for a new setup. Whether you're fixing a slow interface or starting fresh, following these steps will have your Z3 running like new in under five minutes.
If the watch is frozen, won't turn on, or you forgot the screen lock:
The Mibro Z3 usually uses a Nano SIM card. After a reset, you must re-enter the APN settings (Access Point Names) for mobile data.
Are you a parent who has the Mibro Fit app on your phone but the watch is lost or not responding? You can trigger a reset remotely.
