[How To] Unlock Bootloader in Redmi 3s/Prime

Hello MIUIers, Hope you are doing well. Today we discuss bootloader unlocking procedure in Xiaomi Redmi 3S Prime. Nowadays all Xiaomi phones come with locked bootloader. Why ? Because Xiaomi wants to secure their user’s data. So they lock the bootloader. If your Redmi 3S / Prime phone lost or stolen by you then no one can flash a new ROM and they can’t access your personal data which is stored on your phone. So if we see as a normal user then this is the good thing. But you know we MIUIers love to flash new ROMs. We try many ROM on our devices. So as a MIUI fan I don’t like locked bootloaders.
If you want to go in Recovery mode. then you need to unlock the device bootloader. Without the unlocking bootloader, you can’t clear Wipe cachedata. you can not do Wipe reset. even you can’t flash a ROM via update.zip feature. So bootloader unlock is required to perform all these tasks.




APPLY For Permission:-

Step 1 – Open up your favorite web browser in your computer (Chrome is recommended) then go to this Unlock Site

Step 2 – You’ll see the official page of “Unlock Your Mi Device”. Now simply click on the blue “Unlock Now” Button in the middle of the page.

Step 3 – You’ll see a login page in the next page which is in Chinese. If you use Google Chrome to open the page, then you can simply use its built-in Google Translate feature.

Step 4 – Once logged in, you’ll see the Unlock Application Permissions page which is similar to this :

Step 5 – Now simply fill in all required fields then click on that green Apply Immediately button.

P.S: Type in your reason to unlock your device in Chinese language. Use Google Translate for that. Also, make sure that the characters are not more than 10 Chinese character.


Step 6 – In the next page, you’ll need to enter a verification code sent to you via SMS. Check your phone for any SMS verification sent by Xiaomi server. The code is usually valid for only 5 minutes so you need to enter it immediately.

P.S:- The website is slow and takes some time to send the 6 digits code to your phone. Clicking on resend multiple times will block your IP address. If you do not receive the code immediately, please wait for 10 minutes before clicking on Resend to request a new code. If you receive a error pop-up message, please wait for at least 24 hours before you can apply again.

Step 7 – Once you have submitted the 6 digits code, you’ll then be redirected to another page saying that from the point toward all you need to do is just waiting for Xiaomi Developers to review and approve your application. Once approved, you’ll get another SMS which normally arrives between 3 to 21 days. The approval process is manual so just be patient on this.

However for some people might still experience slight problem with their applications. Please do not complain if the above steps didn’t work because unlocking the bootloader is simply not magic trick. If you did receive the SMS that your unlock permission has been approved but your device still rejected it, then I can suggest you to contact their developer  here.
