To check all you have to do is turn off your phone pull out battery wait five seconds then re apply battery and hold power button and volume down for about 15 seconds and it should be stuck at the logo...that's how you know.

and if bootloader unlocked it stays at the huawei logo?

what i did was i rooted using a different tool a while ago (im on ics) and then plugged this in, my phone was on at that time and i ran the bootloader unlock command, it finished and then i unplugged my phone and took battery out then rebooted it. was that right or should i try something else? my phone is network unlocked if that add's any complications.

---edit---
nevermind it wasnt done. went to huaweig300 downloads=ed the bootloader unlock tool and have followed their guide. just backing up on CWM incase anything goes wrong whilst installing custom ROM. any suggestions on the best ROM for G300? :p

Guys,
I solved the problem.

I've just followed the instructions in step 5. on the site xxx and put a new update.app (1 KB) and copy it to the dload. After that I've used main dload (ICS folder, aprox abot 600 MB) and everything updated and installed successfully.

Thanks.

p.s. if anyone has or had the same problem, do not hesitate to ask.

I've got the exact same problem as you but I can't follow the Step 5 you refer to as my PC can't see the SD card or phone memory. How did you get around that?

Hello all U8815 and U8818 user's, this guide will show you how to root and unlock boot-loader for your phone.

CAUTION : DO NOT USE ON GINGER BREAD!

I have gathered up some useful resource that will help you get started, first of all note this will "not"void your warranty, rooting can't void you'r warranty unless if you stuff up the hardware. So if you want to root the G300 go ahead then sure.

This method is by far the safest and easiest method to root for the G300.

Okay first of all you will need to download Unlockbootloader ---> View attachment 1279054

Now once you have downloaded the .zip extract the .exe file inside the .zip to your desktop.

Now turn on USB debugging on your phone. if its already on then skip this part.

Go into Settings>Developer Options and check on USB Debugging.

Now once its on, plug your phone to the computer with your USB cable.

So far everything is done, Unlockbootloader download, USB debug on, and your phone is connected to your PC.

Now run the .exe file you have just extracted.

Now 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 your 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.

Installing CWM Recovery guide coming soon.

Hello!
I succeeded to root my G300 last week, following your instructions.
I am using Vodafone, Romania.
Last night, the phone tried to upgrade, I have ICS on it... the download was about 53 mb . Everything looked that worked ok, the update was installed, till the reboot, when the phone didn't succeed to do it... An exclamation mark appears, saying: "Image signature verify fail!".
Does this happened because I rooted my phone?... :(

This is the exact method I used... if you are getting signature fails... install the latest b952 update and try this method....

    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 ---> View attachment 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.

    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.

    Thanks for that by b927* you are referring to a different version of HDU88151079V100R001C00B934 ?
    where would i be able to get this from?

    so this would give me the stock ics
    what is the advantage of then installing HDU88151079V100R001C00B934 ?


    Thanks

    Your on gingerbread so your baseband Is 109808 and if u flash any b934+ stock using the combinations say goodbye to your phone. I did that to my brothers and it bricked.

    So to get to ice you must install b927 version of ics then your baseband will change to the new one *2030* now you can flash any b934+ stocks because you now have the new baseband.

    Go to modaco and enter the G300 forums and look at the first dew pages all the info and guides you need. Procedure is simple.

    There are some reports of the cm10.1 ROM unlocking network Sim locked phones. Look it up on modaco g300 forum.
