How to unlock Xiaomi Redmi 8 after reset: what to enter in 2026

After resetting the Xiaomi Redmi 8 to factory settings, many users face a problem: the phone requires you to enter data to unlock, but it is not clear what exactly to specify. This situation arises from the activation of Mi Account or Google FRP (Factory Reset Protection) protection. Without the right data, the device becomes a “brick” – even the basic functionality does not work.

In this article, we will analyze all possible unlock scenarios: from entering a Xiaomi account to bypassing FRP (if you forgot your password from Google). We will pay special attention to the nuances of 2026 - changes in Xiaomi's security policy and current methods of restoring access. If you bought a used phone or performed a reset yourself without knowing the consequences, our instructions will help to return the functionality of the gadget without contacting the service center.

Why does Redmi 8 require unlocking after resetting?

Reset to factory settings (Settings → Additional → Recovery and Reset) on Xiaomi Redmi 8 automatically activates two layers of protection:

• 🔒 Mi Account is a Xiaomi tied account that the phone requires you to enter after a reboot.This is a standard brand security feature that prevents data theft.
• 🔑 Google FRP (Factory Reset Protection – Reset protection introduced by Google for all Android 5.1 devices+. Requires login and password from the last synchronized Google account.

If the phone was bought with hands, the previous owner could not untie his Mi Account or log out of the Google account.In this case, unlocking without the previous user’s data becomes impossible by legitimate means. Xiaomi does not officially provide tools to circumvent this protection – all “gray” methods are associated with the risks of blocking IMEI or loss of warranty.

⚠️ Note: If you bought Redmi 8 b/d and the seller did not provide data from Mi Account, return the device or require untidying the account through the official Xiaomi service. Otherwise, the phone may be locked forever after updating the firmware.
