    Now I am not an expert so do this at you own risk. I succesfully fixed my phone (Huawei Ascend Y330-U05) by flashing this official firmware from

    the Huawei site. It is for New Zealand but works for me. My phone now says that it is a Ascend Y330-U07 and everything works.

    I also tried the Y330-U01 Spanish firmware from the Huawei site, but had problems with low network siganal even though the wireless was fine. Another thing, the only version of SP_Flash_Tool that worked was the one that came with the official download from the Huawei site, version 3.1324.0.177_Secboot. All other versions complained about not finding signed header or something similar.

    Backups made with MTKdroid fail because they are not signed.

    Steps I took to revive my Ascend Y330:

    Remove Battery from phone, connect usb cable, check that phone is detected and preloader driver is present under COM Ports in Device Manager. If not present try inserting battery. Experiment until you get it loaded. When preloader driver is listed under COM Ports you are good to go.

    Unplug phone from computer.

    1. Start Flash_tool.exe.

    2. Load scatter file located in the Rework-Secro folder.

    3. Click Download.

    4. Connect phone and enjoy the pretty colors. When the process is finished, A green circle pops up to let you know that everything is ok and you are on the right track.

    5. Disconnect phone from computer.

    6. Load scatter file from the USB_Upgrade folder

    7. Click Download and watch as Flash_tool loads the files.

    8. When the progress bar is at 0%, connect the phone. (Remember what you did to get it detected earlier)

    9. SP_ Flash_Tool will start flashing your phone and after a couple of minutes the "Download OK" popup will be displayed.

    10. Disconnect and reboot your new phone. It will take a while before it completes this first boot, so be patient.

    If you made backups with MTKdroid you can flash these with SP_Flash_Tool. I have succesfully flashed backup files made by following this tutorial.

    1. Select write memory from the window tab.

    2. Click write memory.

    3. Change Memory setting to EMMC.

    4. Browse for the file you want to flash (EBR1, EBR2, Nand and Cust). 

    IMPORTANT —>[DO NOT flash the Secro.img, If you do the phone will refuse to boot and you will be back at  square one.  I would not bother with the system, boot or recovery files, simply because the phone is now working and we are only trying to customize it.]<—- IMPORTANT.

    5. Open the scatter file with Notepad++ or similar and copy the linear_start address for the file (partition) you want to flash, paste into  the SP_Flash_Tool "Begin Address (Hex):" box.

    6. Back in Notepad++, copy the partition_size hex value and paste into the "SP_Flash_Tool" Container Length (Hex): box.

    7. Double check that you have selected the correct file, verify the start address and partition size.

    8. If you are certain that everything is correct click write memory to begin flashing. When it is finished unplug phone and reboot.

      Did you follow all the steps listed above, exactly?

      Try, Format —> Format whole flash except Bootloader first and try again.

      If that doesn't work try, Format —–> Format whole flash and start from beginnig.

      I just double checked my phone  and I am able to use Digicel or CW in mine.

      Good Luck.
