FAQ

Take 5 minutes to read

- What is the bootloader and what is it for?

- The loader is responsible for starting the system, as well as for launching the recovery.

- Why do I need to unlock the bootloader?

- To install custom recovery, which in turn allows you to quickly install and reinstall the system, install various patches, add-ons that improve the system, add new features, and create and later restore backups.

- Why did Xiaomi block it?

- This is a requirement of Google, as well as for the safety of your data in case of loss of the device.

- Does unlocking the bootloader affect the warranty?

- No.

-How to unlock the bootloader?

Method 1. Go to Xiaomi Mi Unlock Website Mi Unlock website.

Method 2. Download Mi Flashtool

- Are there any other ways to unlock without applying?

- No!

- How to lock Bootloader?

Method 1. fastboot oem lock

Method 2. Using MiFlash (clean all and lock)

- How to check the status of the boot loader on your phone

Method 1. fastboot oem device-info and see the lock status of your bootloader Device unlocked : false (locked or unblocked) or true (unlocked).

Method 2. check developers option

-When unlocking, does the hard reset occur? (factory reset, or reset data)

No, unlike unlocking HTC, Motorola ... unlocking occurs without loss of data but if the data on the phone is encrypted, you must first disable the encryption, otherwise the data will be lost. Then unblock and you can turn on encryption again. Exceptions are Mi6, Mi Note 3, Mi Mix 2, Mi Mix 2s. They have a complete discharge. And it looks like this trend applies to all fresh models.

- How do I know if I get a permit?

- There will be a message on the phone with a link to the download page Mi Flash Unlock. It happens that the SMS does not come. Therefore, it is better to check in parallel on the site and / or in the unlock program.

- What does the "factory unlock" item in the developers menu mean?

- Opens or closes access to the bootloader, an additional security measure.*This is NOT an unlock.*

- How to unlock the new (other) phone after the already-used (used) unlocking?

Enter Mi unlock under the same account, to which the request was made, to unlock.

an application for unlocking is not necessary to send again.

for 1 account -> 1 phone in a calendar month, i.e. from the 1st day of each month you can unlock the next unit.

-What are the terms for unlocking the boot loader, starting from the moment of sending the application.

Now the approval comes quickly, from 1 minute to 12 hours, very rarely up to 3 days at the same time on the phone must be installed official firmware, synchronized Mi account, MiCloud.bFor Mi4c and Mi Note Pro, wait for synchronization on the server in 5-8 days (on android 5.1) and quickly (as in the other models) on android 7.

-After the first unlock attempt, the wait count is turned on in 72/360 hours (if the phone's binding was recently).

-If you unlock another phone with a confirmation account, you will have to wait 72/360 hours again.

-One and the same phone, after the first unlock, can be unlocked at least every 5 minutes (if you can block it again).

- When unlocking, I see a message that some functions, including "Finger Scanner", "Device Search", will be unavailable.

A little misinterpretation (the fault of translation from Chinese into English and beyond). Functionality will remain and will work. PROTECTIVE properties will become weaker; you will have access to the system and the ability to disable this functionality.

- The bootloader unlocked, but when I try to enter the recovery, I also see the phone with the cable.

This is normal. The form of the recovery does not change (there remains a recovery with a closed external entrance). This does not interfere with flashing official firmware. Also, you can flash and use TWRP. Instructions for flashing, TWRP and firmware are found in the firmware of your device.

- I changed the phone and can not apply for the unlock again, it is offered to download the utility right away.

- Approval for unlocking is given to the account, not to a specific phone. Therefore it does not matter whether you have a phone on hand or not, you can change the phone - approval remains and you can unblock further your other phone, and even someone else's phone, but no more than 1 device per month, i.e. starting from the 1st day of the following month.

- Will I be able to receive OTA updates after unlocking the bootloader?

- Unlocking the bootloader does not affect the mechanism of OTA updates. As it was with the blocked, it will also be with the unlocked.

- Do you need a SIM on the phone when unlocking?

- We recommend without a SIM card.

- I forgot the pattern of the input and can not login.

- Unlocking the bootloader is not related to the forgotten graphical key, installed on the entrance to the phone, and to the activated "anti-theft". First, deal with these problems, and then unlock the loader (if this is still necessary) and not the other way around.

- For how long is the permission to unlock the bootloader?

- permission to unlock the bootloader is given forever.You can use it at any time, not necessarily right away.Autumn (2016) and February (2017) database crash in xiaomi is a force majeure, and not a real withdrawal of permits.

- Is it possible to lock the bootloader if I have a localized firmware and TWRP?

- It is impossible to lock the bootloader from unofficial firmware and TWRP.

- Is windows important when unblocking?

- We recommend Intel 64bit systems

-"revoked" permission to unlock.

-When I sign in, I get an error.

- You can try to enter the login ID in the login field, not the phone number, but the account ID.

-Error "Network Error"

- The problem in the server is xiaomi, the Chinese wall (firewall).You can try to clean cookies in the browser, use an anonymizer (VPN gateway), for example, some here have used TunnelBear, but you can also others. Some of this problem occurs on the provider Beeline and helps to call through another provider.

-When I try to add my phone to the database (via the developer's menu), we get the error*10008

- The problem in the router / provider / Chinese firewall. You can try to use a VPN.

-When trying to tie the phone through the menu Mi Unlock status (in the developer's menu) error*86006*pops up

- This sometimes happens on stable firmware. If nothing helps, then put the developer (through the system update).

-I bought the phone, and it turned out to be with the unlocked loader. How so?

- On phones coming from the factory with Chinese firmware, sellers patch the bootloader to install the global firmware.

-When I try to bind the phone to the developer menu, I get the message "connect to the network and try again".

- Sometimes it helps to turn off the phone location search.

-Unlocked the bootloader, installed TWRP, root and now the phone shows that the loader is locked.

- If magisk is used as a root, it hides the real state of the loader from the system.
