How to know the time before unlocking the Xiaomi bootloader

Unlocking the bootloader on Xiaomi, Redmi or POCO smartphones is a must for custom firmware installation, root rights or device recovery after software failures. However, the company imposes a time limit: once an account is linked to a device, you have to wait 72 hours to 360 days before the Mi Unlock Tool allows you to unlock, a measure aimed at combating device theft and unauthorized access.

The main problem is that Xiaomi does not display the remaining latency in the smartphone interface. Users often face a situation where after several attempts to unlock the message “You need to wait XX hours” without specifying the end date. In this article, we will discuss all the working ways to check the waiting timer, including hidden methods through ADB and Fastboot, and explain why the deadline can suddenly reset or increase.

Why Xiaomi is blocking the bootloader and how long to wait

Since 2017, Xiaomi has tightened its security policy by linking the bootloader unlock to the device’s Mi Account.

• 🔒 Prevent theft – a thief will not be able to reset the phone through Fastboot without knowing the username / password of the owner.
• 🛡️ Protection against malware installation – custom firmware may contain backdoors.
• 📱 Preserve warranty – Unblocking will void official support.

The waiting period depends on the date of the first account binding to the device and the unlock history:

Important: If you delete a device from your Mi Account or change your account, the timer is reset and the countdown starts again, and the time limit can increase if:

• 🔄 You tried to unlock the bootloader on another PC.
• 📱 The device was reinterpreted by an unofficial firmware.
• 🔧 Reset via Fastboot (e.g., the fastboot erase userdata command).

Checking with Mi Unlock Tool

The most reliable method is to use Xiaomi’s official Mi Unlock Tool, which shows an accurate waiting timer, but requires preparation:

Enable USB debugging in Settings → About Phone → MIUI version (click 7 times)

Connect the device to the PC with the original cable

Install Mi USB Driver (download from official website)

Sign in to Mi Account on the phone and utility

-->

Instructions for verification:

1. Download Mi Unlock Tool from the official page (select the version for your OS).
2. Launch the utility on behalf of the administrator and log in under the same account as on the phone.
3. Connect your smartphone in Fastboot mode (turn off your phone, then press Volume Down + Power).
4. If the waiting time has not expired, a message will appear: Current account is different from the account info on the device. You need to wait XX hours to unlock this device.

🔍 What do errors mean:

• 🚫 Couldn’t unlock – the device does not support unlocking (check the model on the Xiaomi website).
• ⏳ Wait XX hours – the exact time before unlocking (XX — clockwork).
• 🔄 Device is locked – account unlinked or reset.

💡

If the utility does not see the device, try disabling the driver signature in Windows: type bcdedit /set testsigning on in the command line and restart the PC.

Alternative ways to check the timer

If the Mi Unlock Tool doesn’t work (for example, due to IP blocking or Xiaomi server errors), workarounds can be used. They are less accurate, but help estimate the approximate latency.

1. via ADB (no Fastboot)

This method is suitable for devices with enabled debugging over USB and does not require rebooting in Fastboot:

1. Connect the phone to the PC and allow debugging.
2. Open the command line in the folder with ADB and execute: adb shell su getprop | grep unlock
3. Look for lines like ro.boot.flash.locked=1 or ro.oem_unlock_support=1. If the value 1 — loader blocked.

📌 Unfortunately, ADB does not show a waiting timer, but will confirm whether the bootloader is unlocked.

2. Through Fastboot teams

For devices that are not defined in the Mi Unlock Tool, you can manually request the lock status:

1. Transfer the phone to Fastboot (Loudness down + Power).
2. Command: fastboot oem device-info
3. Device unlocked: false (bootloader) Device critical unlocked: false (bootloader) Charger screen enabled: false If unlocked: false, bootloader is locked.

3. Verification through service codes

Some Xiaomi devices have a hidden service code to check the lock status:

1. Open the Phone app.
2. Enter the combination: ##4636## → Select Phone Information.
3. Scroll down to the Bootloader block. If it's missing, it's not supported.

💡

None of the alternative methods show an accurate waiting timer, they only confirm the lock status. For accurate information, use only the Mi Unlock Tool.

Frequent Mistakes and How to Avoid Them

Users often encounter problems checking the timer, and here are the most common errors and solutions:

⚠️ Note: If you see a message saying "This Mi Account is associated with too many devices," it means that more than 3 devices have been linked to your account in the last month. Xiaomi blocks unlocking in this case.

Error 1: "Couldn't receive device message" in Mi Unlock Tool

• 🔌 Check the cable – use the original from Xiaomi.
• 🖥️ Install drivers manually via Android SDK.
• 🔄 Restart your phone and PC.

Error 2: The timer is reset after the MIUI update.

This is because Xiaomi has tied the timer to the firmware version, and once it's updated, it can see the device as "new."

• 📵 Don't update. MIUI unlock.
• 🔧 If the update is already installed, you will have to wait again.

Error 3: The utility doesn’t see the device in Fastboot.

The problem is often due to the lack of driver signatures. For Windows:

1. Open Device Manager.
2. Find a device with a yellow exclamation point (usually Android Bootloader Interface).
3. Update the driver manually by specifying the folder with the Mi USB Driver.

How to speed up unlocking: myths and reality

There are dozens of ways to get around the waiting timer online, from changing the date on your phone to using hacked versions of the Mi Unlock Tool, 99% of which don't work or lead to account locking.

🔹 The only working way to speed up unlocking is to use an account that has already unlocked the bootloader on that device before. For example, if you sold your phone and the new owner wants to unlock the bootloader, ask the old owner to link back to your account – this can reduce the waiting time to 72 hours.

⚠️ Warning: Some "masters" offer timer bypass services for money. Most often they just wait until the deadline expires and then unlock in the standard way. Don't pay for something that can be done for free!

What to do if the timer has nullified or increased

Sometimes users are faced with a situation where the expected unlock time is suddenly reset or increased.

1.Timer resets after resetting settings

If you’ve done Hard Reset through Recovery or Fastboot, Xiaomi is treating the device as new.

• 🔄 Re-connect the same Mi Account.
• ⏳ Wait 72 hours – usually the timer returns to the previous value.

2 Waiting time increased after MIUI update

This is due to Xiaomi’s policy that when you update your firmware, servers may request additional verification.

• 📵 Do not update the firmware before unlocking.
• 🔧 If the update is already installed – contact Xiaomi with a request to reset the timer (you will have to confirm ownership of the device).

3.The utility shows "Too many attempts"

This means you have tried too often to unlock the bootloader (more than 3 times a month).

• ⏳ Wait 30 days without trying to unlock.
• 🔑 Use a different Mi Account (but this will reset the timer!).

1) Have you changed your Mi Account on your phone?

(2) Have there been any MIUI updates or resets?

(3) Have you connected to the Mi Unlock Tool from another PC?
