How To Unlock Bootloader On Sony Xperia Z Ultra

Unlocking the bootloader allows you to put custom ROMs, kernels and boot images on your Xperia Z Ultra which cannot be done otherwise. Say you want to install an AOSP based ROM on your Xperia Z Ultra which need to change the boot image on the device to be compatible with the AOSP code then it can only be done by unlocking the bootloader on your device.

Generally, rooting and custom recovery installation also requires an unlocked bootloader, but thanks to the developer community at work for Xperia devices that root is often achieved even without unlocking the bootloader.

Also thanks to Sony for having their entire range of Xperia devices released since 2011 to be bootloader unlockable. Not every Android manufacturer does that, at-least not so easy.

The bootloader unlocking process on Xperia Z Ultra is fairly simple. And with our step by step instructions with screenshots below, even noob users will be able to do it easily.

Two methods of unlocking the Bootloader on Xperia Z Ultra

There are two methods you could choose from to unlock the bootloader on your Sony Xperia Z Ultra

Unofficially using Flashtool: You can unlock the bootloader on your device using a program called Flashtool. Getting the bootloader unlocked through flashtool is very quick compared to Sony’s official way of doing it. And on a plus note you also save yourself from letting Sony know that you tried to unlock your device’s bootloader (which voids warranty)

Officially from Sony’s website: You can follow Sony’s official way of unlocking the bootloader which is also simple and easy to follow, but not as friendly as Flashtool. In the official method you’ve to get the bootloader unlock key from Sony’s website, which lets the manufacturer know that you intended to unlock your device’s bootloader (which voids warranty) by provding them your phone’s IMEI number to get the key.

Below are full step by step installation instructions for both the methods discussed above. So proceed with whatever method you think is best. In our opinion, go with the Flashtool method. It’s much easier to unlock bootloader using Flashtool.

You’ll void the warranty of your Sony Xperia Z Ultra by unlocking its bootloader.

Back up your important data!

Every single file on your device will be deleted once you unlock the bootloader. So make sure you back up all your important data before proceeding with the guide given below and also make sure to move your back up files to your PC or Cloud storage because even any backup file kept on the phone will be deleted.

Check out the link below if you need any help with backing up your device.

Method 1 – Unlock Bootloader using Flashtool

Flashtool is a multi utility program for Xperia devices that does a lot of tasks in much easier ways compared to Sony’s official ways. Here in this guide we’ll be using flashtool only for the purpose of unlocking the bootloader.

Download and install Flashtool

Install Flashtool to the directory of your choice

Instructions for unlocking bootloader using Flashtool

Start/Open Flashtool

You’ll see a window asking you to connect your device in Flashmode. You can ignore the animated instruction on the screen as it’s not meant for the current generation of Xperia devices, instead follow the instructions given below to connect your Xperia Z Ultra to your PC in Flashmode

Switch off your phone

Now while holding down the Volume Down key on your phone connect it to PC using a USB cable

Your device should now be connected in Flashmode and Flashtool should show a ‘Device selector’ pop-up window

Select ‘Sony Xperia Z Ultra’ from the list of devices in the ‘Device selector’ window

Have fun!

Method 2 – Unlock bootloader using Sony’s website

Unlocking bootloader using Sony’s website would require you to first get the unlock from Sony’s website and then run a couple of fastboot commands using command prompt on your PC.

Getting the bootloader unlock key from Sony’s website

Open this link in a new tab or window → http://unlockbootloader.sonymobile.com/unlock/step1

Check for new mail on the E-mail address you provided in the form above with the subject line ‘Your requested unlock boot loader key’. Open the mail and you’ll see your bootloader unlock key.

Save your bootloader unlock key in your Notepad, a text file or anywhere you could remember and refer back quickly.

Unlocking bootloader using the Unlock Key

Now we’ll run some fastboot commands on your PC and for that you’ll need to download some fastboot files on your computer. Below is the download link:

Extract the fastboot file you downloaded from the link above and open the folder where you extract it

Now connect your phone in fastboot mode

Switch off your phone

Hold the Volume UP key on your phone and connect it to PC using a USB cable

On the command prompt window we opened in Step 2 type the command given below and hit enter. This is to verify that your device has connected properly (check the screenshot below for reference) fastboot.exe -i 0x0fce getvar version

Now you’re going to run the main bootloader unlock code. So make sure you’ve backed up your important data on the phone because once you unlock the bootloader every single file on your phone will be deleted

Paste/write the following command in the command prompt window. Do NOT hit enter yet fastboot.exe -i 0x0fce oem unlock 0xKEY

Replace the last word in the command (KEY) with your bootloader unlock key that you received from Sony via E-mail. Your command should look like this fastboot.exe -i 0x0fce oem unlock 0x636FF374683A24EF

Hit enter once you’ve put your unique bootloader unlock key in place

Have fun!

Hướng Dẫn Root Sony Xperia Z3C Dùng Unlock Bootloader

Với Z3C trong bài viết này cũng vậy, trước tiên là chúng ta sẽ root máy. Khoan hãy nghĩ đến việc cài rom cook, tận hưởng khả năng vô tận của root trước. Mục đích mình root máy cũng là để cải thiện giao diện của Z3C, vì màn hình của máy thì bé mà các phím điều hướng cũng như thanh thông báo chiếm quá nhiều diện tích. Phần tuỳ chỉnh sẽ được trình bày ở cuối bài viết.

A – Unlock Bootloader Sony Xperia

Để có thể hình dung rõ hơn về sự ảnh hưởng của việc unlock bootloader thì bạn có thể tham khảo bài viết sau: Cần lưu ý trước khi unlock bootloader của Sony Xperia Z2. Lưu ý là Unlock Bootloader sẽ xoá toàn bộ dữ liệu hiện tại đang có trong máy!

Các máy Sony Xperia đều có chung một cách Unlock Bootloader nên mình sẽ trình bày riêng 1 phần để bạn nào dùng máy Xperia khác cũng có thể tham khảo được. Cách thức unlock được Sony trình bày rõ ràng trên http://unlockbootloader.sonymobile.com/

1 – Cài driver

Lưu lại IMEI của máy: *#06#

Tải về driver của máy FlashTool Xperia Driver Pack , sau khi tải xong nhớ cài đặt, chọn đúng thiết bị bạn đang sử dụng.

Sau khi driver đã được tự động cài xong thì bạn có thể ngắt kết nối và mở điện thoại lên.

2 – Unlock bootloader

Truy cập vào: http://unlockbootloader.sonymobile.com/ và kéo xuống dưới cùng chọn điện thoại bạn đang dùng (ở đây là Z3C). Nhấn “Continue”

Bước tiếp theo là nhập IMEI của bạn vào, nhấn *#06# để lấy IMEI

Sau khi đã nhập IMEI thì bạn sẽ thấy dòng thông báo Your unlock code: 9A36A1F027862A92 (dãy số này khác nhau tuỳ máy)

Giờ thì giải nén file fastboot package ra, được 1 thư mục. Nhấn chuột phải trong thư mục đó và chọn ‘Open command window here’.

Trong cửa sổ command window gõ vào fastboot.exe -i 0x0fce oem unlock 0xKEY với KEY là unlock code của bạn, có được ở bước 4. (như trong trường hợp này thì KEY là 9A36A1F027862A92)
