How can I root Huawei Y300 firmware

[HowTo] Unlock bootloader and activate root account - preferred variant

You can find the original instructions HERE - huawei-y300.tumblr.com and was translated into German by me to the best of my knowledge and belief. If in doubt, simply consult the source.


Attention: The procedure, which is described in the following, will very likely invalidate the warranty claim of your smartphone (although there have already been other experiences). This process is a change that affects the system deeply and you bear full responsibility for any consequential damage.


Annotation:

There are 3 different revisions of the Huawei Y300
1. Huawei Y300 (T8833) - TD-SCDMA / China Mobile
2. Huawei Y300-0000 (U8833) - WCDMA China Unicom
3. Huawei Y300-0100 (U8833) - WCDMA International

The following tutorial is explicitly only for the models with WCDMA support.

What you need:
• Huawei Y300-0000 or Y300-0100 (U8833) - How do I know?
• Windows PC
• UnlockTools including stock recovery
• optionally the current version of the mini operating system of the TWRP
• optional (see point 4) the current version of the SuperSU.zip for mini operating systems
• Downloads - Huawei Device Co., Ltd ..



1. request the appropriate "unlock code"
First the bootloader has to be unlocked.

Y300-0000:Visit this page (have it translated into German with the help of Google Translate and select your model Y300-0000 and make all the required information.)
Y300-0100: Write an email to [email protected] in the following form:

Subject: requesting bootloader unlock code for HUAWEI Y300-0100
Text:

• Model: HUAWEI ASCEND Y300-0100 (U8833) WCDMA
• S / N number (on the label under the battery) Calmly point out different S / N (battery slot and status) with screenshots or photos
• IMEI (Settings -> About phone -> Status -> IMEI)
• Product ID ("telephone receiver" symbol and then enter * # * # 1357946 # * # *)

or

Thanks to the reference from canidas you can now request the UnlockCode for your Y300 directly on the dedicated website.
  • just go to the website that has been set up accordingly
  • accept the conditions by ticking the box
  • make all necessary entries
  • Product type: Smartphone and Product model: HUAWEI Y300-0100 (model: depending on what your phone information spits out. See the screenshot in the appendix)
  • Send the data to HUAWEI by clicking on "Submit"

Wait 2-3 days until the "unlock code" arrives via email.



Important! Write down the unlock code somewhere, save the mail or take a screenshot of the mail. The main thing is that you secure the code. This code is unique for each device and cannot be used on other devices. Who knows what it will be used for.



2. Unlock the bootloader

Before we unlock the bootloader, we make sure that your Huawei Y300 has been properly recognized by your PC.

1. Create a backup of all personal data + apps on the SD card with HUAWEI's own data backup app.
2. On the Y300: Settings -> Developer options and check USB Debugging.
3. Unzip the downloaded UnlockTools.zip to the desktop.
4. Start the Huawei-Handset-WinDriver.exe and install the driver. If you have problems with the installation, you can read more here.
5. Turn off the Y300, remove the battery, wait 5 seconds, and then reinsert the battery. Please carry out point 4 conscientiously, otherwise the following steps will not work!
6. Hold down the "Volume minus" rocker and switch the Y300 on. Keep the "Volume Minus" rocker pressed for at least 10 seconds after switching on. The Y300 stops at the start logo (fastboot mode).
7. Release all buttons and connect the Y300 to the PC. The PC should now find and recognize a new device.
8. Now open the “UnlockTools” folder on the desktop and start “check_bootloader.bat” with a double click. This batch checks that your Y300 is correctly connected to the PC and recognized and that the bootloader still needs to be unlocked.
If everything was done correctly, a DOS prompt should appear in which your Y300 is listed and after pressing any key you will see the boot loader status "LOCKED". (Minimize the window in the task, do not close it and do not press any key in the active window -> otherwise reboot and everything from the beginning ...)
9. From the same directory on the desktop, start "unlock_bootloader.bat" with a double click and, when prompted, enter the 16-digit unlock code from the response email received from Huawei.
10. The Y300 will do a few checks, restore the factory settings, and eventually reboot.
The minimized DOS prompt from earlier can now be closed.

additionally:
You can repeat steps 4 - 7 to check that the bootloader has been unlocked. The status should now be "UNLOCKED".





3. Flash custom recovery

Now we are going to flash the Custom recovery TWRP v2.5 for the Y300. The Stock Recovery can also be flashed again with the following instructions. See the "HowTo_flash_Recovery.pdf" in the folder "Recovery images".

Annotation: TWRP is a user-defined recovery with functions similar to ClockworkMod but with the option of making all inputs via the touchscreen. More information is available on the developer page.

1. Turn off the Y300, remove the battery, wait 5 seconds, and then reinsert the battery.
2. Hold down the "Volume minus" rocker and switch the Y300 on. Keep the "Volume Minus" rocker pressed for at least 10 seconds after switching on. The Y300 stops at the start logo (fastboot mode).
3. Connect your Y300 to the PC.
4. From the “UnlockTools” directory, start “flash_recovery.bat” with a double click and follow the instructions.
5. When the recovery has been flashed successfully, your Y300 will restart (this may take a while).

Danger: There are 2 options to continue using TWRP.
1st method: remove the battery each time, wait 5 seconds, insert the battery and then call up TWRP with the key combination, or
2. Method: Start the Y300, deactivate Settings -> Fastboot (quick start) and then you can boot into the TWRP with each restart using the key combination without removing the battery first.





4. Flash Backup & SuperSU (Superuser)


1st variant

1. Turn off your Y300. Hold down the "Volume Plus" rocker and the "Power" button at the same time until the TWRP recovery menu appears.
2. First create a backup of the system under TWRP.
3. After the successful backup, select the option to reboot.
4. You will be asked whether the device should be rooted. Confirm this question with YES and restart the mobile phone.
5. After the start comes a query (Play or TWRP) and we click on Play. Here the binaries are completely reloaded and the superuser would be installed successfully.




2nd variant

1. Copy the downloaded "UPDATE-SuperSU-v1.25.zip" to the root of the SD card.
2. Turn off your Y300. Hold down the "Volume Plus" rocker and the "Power" button at the same time until the TWRP recovery menu appears.
3. First create a backup of the system under TWRP. and then on "back" (arrow) to the main menu.
4. In the menu we then select “Install” and refer to the “UPDATE-SuperSU-v1.25.zip” on the root of the SD card.
5. After successful installation, we select “Reboot system” to restart the Y300.


THAT'S IT! If you see a SuperSU symbol on your Y300 after restarting (see screenshot), the "rooting" was successful.



A click on "Thank you" is a welcome motivation .

Thanks to: minotaurus (note Fastboot) and Thorson (note menu item developer options) and all other users who have reported again to successfully receive the unlock code.
