Special thanks to winston.tran1 for providing a copy of his system backup, good luck with further development.

For those who cannot unlock the bootloader or install a recovery, but still want SuperUser root access, below is the link to a tutorial from theprincemoh on how to do so.
http://forum.xda-developers.com/showthread.php?p=43504979#post43504979



  1. Introduction
    This works on all models of the Huawei Ascend G600 device, I used on my U8950N-51.
    Please keep in mind that I am not responsible for any possible damages to your phone.
    This may void your warranty. You could brick your phone if you do not follow the steps carefully, so please take your time.

  2. Unlocking the bootloader
    Your device restores to its' factory settings, so please back up your data.
    1. Request your unlocking code here from the Huawei Website. It may take a few weeks to your receive your code (for some it has even taken months), so ensure you send the correct details and wait patiently.
    2. Ensure the ADB drivers are set up, here is the official Huawei application for phone drivers.
    3. Download the adb_tools-2.0 from here, and place them in the root directory of your hard drive. For simplicity's sake, we will say it is placed on 'C:\'.
    4. Switch the device to Fastboot mode. To do this, first switch of the fast booting feature (in the settings menu), then power off the device. Next, hold the power and volume down keys simultaneously for at least 10 seconds. The Huawei logo should appear and stay on the screen. Your device is now in Fastboot mode.
    5. Connect the device to the computer with a with a USB cable.
    6. Open the command prompt (search for cmd) and navigate to the directory where the 'adb_tools-2.0' are located. As I said before, for this example I placed them in 'C:\', so I would type 'cd C:\adb_tools-2.0' (cd means 'change directory), then hit enter.
    7. Now for the unlocking. In the computer’s command window, enter:

      fastboot oem UNLOCK PASSWORD, (for example, 'fastboot oem unlock 1234567812345678').

      If your unlocking is successful you should see something like:

      'C:\adb_tools-2.0>fastboot oem unlock 1234567812345678
      (bootloader) Unlocking ...

      OKAY [ 0.039s]
      finished. total time: 0.040s
      '

    8. Your device will restart. Now we will check to see if the unlocking has succeeded.
      Enter 'fastboot oem get-bootinfo'. The bootloader lock state of your device is displayed.
      Bootloader Lock State: LOCKED indicates that the bootloader is still locked, and either you completed this method incorrectly or something went wrong along the way. Try repeating the article, and seek help from developers and other sources if possible.
      Bootloader Lock State: UNLOCKED indicates that your device’s bootloader has been unlocked, and you can now proceed to rooting your device. :highfive:

  3. Rooting the phone
    In order to root the phone, you will need the 'Root' zip file and a custom recovery to install it.
    Firstly, download both these files below:
    1. Root File
    2. Recovery File

    Now that we have the files downloaded, we can begin the rooting process :)
    1. Extract 'U8950D_Mssff_touch_recovery.7z'
    2. Turn off your phone
    3. Hold the Power and Volume Down keys for at least 10 seconds to enter fastboot mode.
    4. Connect your phone to the computer with a USB cable.
    5. From the extracted 'U8950D_Mssff_touch_recovery.7z' archive, run the 'flash_RECOVERY.bat' script (just double click on it). A terminal should open and show the Fastboot commands flashing the recovery to your phone.
    6. Your phone will restart. Once it does, place the 'Root.zip' file onto your phone's SD Card.
    7. Turn off your phone.
    8. Hold the Power and Volume Up keys for at least 10 seconds. Your phone will enter recovery mode.
    9. Navigate through the menu using the volume (up and down) and power (select) keys, or simply by touching the buttons.
    10. Choose "install zip from sdcard", then select "choose zip from sdcard"
    11. Select "root.zip", and comfirm "Yes" to install
    12. Once completed, select "reboot system now"

    And that's it! Your phone will restart and you will now see the "SuperUser" app in your menu.
    Your phone is now unlocked and rooted, and you can start developing! :good::laugh::victory::angel:

I have a question... 3 smartphones i have to chose one... Huawei Ascend G600 or LG Optimus L9 or HTC Sensation 4G? help and tell me the reasons to chose that one ...thanks

I would recommend the LG Optimus L9, for the following reasons:
> HD 1080P Video Recording
> Biggest battery out of the three phones
> Has NFC (like the Huawei Ascend)
> Biggest screen, though all have the same resolution anyway
> Has the most RAM

I would not expect updates to come quick though, if at all, LG have a horrible history with smartphone updates and I know this because I was one of the people who waited for the LG Optimus 2x ICS Update. A custom Jellybean ROM was released by Ricardo Cerqueira before LG even released their horrible poorly made ICS 4.0.4 ROM

But if updates aren't a concern, definitely go for the LG phone :)

Please hit thanks if this helped you

But all that said, the HTC is the only of fhe three which supports 4G
So the mobile network could be very quick with it

Basically, dont consider the Huawei Ascend because the other phones offer much more
And only choose the HTC if you really want 4G
Otherwise, go for the Optimus L9

If price is not an issue, your best bet is the Motorola Razr MAXX, simply because it has a HUGE battery, a very good processor, 1GB of RAM, a very nice screen, and a bunch of nice features such as HDMI out.
However, please be aware that it requires a micro sim, and if that would be an issue then choose the Galaxy.


Please hit the 'thanks' button if this or my other posts have helped, really appreciate it

thank you so much, but if I add the Motorola Razr MAXX ,Samsung Glaxy S2 ,htc sensation xe and LG Optimus 3d?? whats the best choise between these smartphones?

I have a Huawei U8950-1.

I wish to boot loader unlock it as per the instructions provided on Huawei's website : http://www.huaweidevice.com/worldwide/servicePolicy.do?method=preUnlock

I have already registered for the Bootloader Unlock code and am waiting for their reply.

Does anyone has any experience with this device ? I am doing this for the first time. Can anyone kindly provide any suggestion.

Has any one done this on Ubuntu ?

Not received the bootloader code yet.
Any idea how long do they take !

Unfortunately, i can not say for certain. Huawei customer service is good, but being such a big company, they have to respond to many requests, so it might take a little while :)
For me, it took just under a fortnight, so not too long
