Default [GUIDE] [Huawei Ascend G300] Unlock bootloader and gain root access.

Quote:
Welcome all Huawei Acend G300 users, this is a full guide prepared by me which will help you unlock your bootloader and not only that but it will help you gain root access for system modifications and root required applications.
Keep in mind, this method is not confirmed working if you're running android 2.3.x [ Gingerbread ]. So do not use this if you're running it. Also dual sim ones aren't supported from what I see it tempers with the phone, I haven't tested it but many have reported it doesn't work on dual sims.

Lets get started shall we? Firstly I have gathered up some useful resources that will help you get started. Make sure you read this guide first, from top to bottom. Then continue. As you must have a clear understanding on what you are going to attempt. If you have any queries don't hesitate to ask on the thread itself.
I have performed these exact steps and have successfully unlocked my bootloader and rooted the phone. So if you're worried. Don't be. After attempting this I haven't noticed any issues either.

Okay, first of all you will need to download Unlockbootloader ---> unlockbootloader.zip

Once you have downloaded the said .zip extract the .exe file inside the .zip to your desktop.

Continue by turning on USB debugging on your G300. if its already switched on then skip the part below..

Go into Settings>Developer Options and tick the USB Debugging option.

Once its switched on, plug your phone to the computer using a USB cable.

So far you've downloaded Unlockbootloader, have switched USB debugging on, and your phone is connected to your PC.

Now run the .exe file you have just extracted. Click "Root" and let it do everything, it will prompt up with a few warnings saying don't use your keyboard because CMD is running.

Once the setup finishes, your phone should be rooted.

Head into the app drawer, and if you see "SuperUser" you're now officially rooted.

Reboot your phone to finalize the rooting and exploits.

Ok, now for the bootloader.

Once your phone is on, and connected again to the PC with debugging mode on, run the .exe file again and this time click "Unlock BootLoader".

Wait for it to do its job, once done reboot again and you now have a Stock Rooted and Bootloader unlocked ICS phone.
If this Guide helped, don't hesitate to hit the thanks button.

Hi, assuming you have installed the g300 adb drivers, once the device is hanging on the boot logo and you connect the usb cable. You need to wait for windows to fully the load the adb driver before you use the unlockbootloader.exe program.

What you have to do is,turn on debug, then power off device fully by pulling off battery then putting it back in, now you must power on by golding the volume down button and power button at the same time, this should get it to be stuck on the huawei logo screen, now plug in your USB cable and wait for you PC to detect the phone and it should automatically install the devices driver's, one its done the now open the folder and run .BAT files, If you are experiencing problems here's a link for another guide : View

Hi,

After the "Unlock BootLoader", my phone doesn't boot. When the logo appears it stars to reboot again and never goes beyond that.

Any ideas ? Have I killed it ?
