Flash ROM / Firmware with SP Flash Tool On (MTK) MediaTek Based Huawei Smartphone By BuntyGSM Mobile Repairing Institute

What's needed:

First of all, make sure that you have MediaTek DA USB VCOM drivers installed.

Flashing the whole ROM

First of all open SP Flash Tool, then click Scatter-loading button to load the correct scatter file
(MT6575_Android_scatter_emmc.txt or MT6577_Android_scatter_emmc.txt, depending on which phone you have) for your device and ignore any message that may appear.

The process will start and a red progress bar will appear.

Flashing only part of the ROM

Attention : Please follow the instructions carefully. I will not take any responsibility on whatever may happen with your phone.

Very important warning : Always make sure that you trust the sources of the ROM you download and know that it is meant for your phone. After flashing a wrong preloader, your phone will be completely dead (can't be powered on, it will not charge and won't be detected anymore by the computer).
