Android developers and porters put an efforts to made it possible for us but chances of bricking your device is possible, much worse we came up with a dead boot Android phone. How can we prevent such circumstances? There are no guarantee that the custom or modified ROM is 100% compatible to our device, in that case, what you need is a backup of your current ROM. This time I will be specific, our guide for today is creating a full dump ROM backup in several Mediatek devices. How to determine if your Android phone is Mediatek?, for we to be able to check whether your Android phone is Mediatek powered or not, first download CPU-Z from Google play, Open CPU-Z and under SoC tab, if you see an MT65xx or MediaTek logo that means your device is using a Mediatek chipset. So you have now an idea, once you confirm that you’re using a Mediatek device let’s proceed to the step below.
What you need
- First install the MT65xx USB, driver.I made a separate guide for that, for Windows 7 operating system click here and for Windows 8 to the latest, follow the guide here.
- Once you successfully installed the driver. Make sure your USB debugging is enabled. Your desktop computer will be able to read your device. Open MTK Droid tools, wait until your device is detected.
