If there is something that differentiates Android devices from iOS devices with their great ability to be customized and modified at the software level (operating system). However, these modifications and customizations can lead to certain problems, such as the instability of the Android system. This instability may be due to the installation of unofficial ROMs, the installation of Advanced Recovery Modes or the rooting among many other reasons.

One of the most common changes in Android devices is the replacement of the factory ROM which incorporates numerous applications from the manufacturer, for an unofficial ROM which is much lighter, making your device work in a much more fluid way. However, this process can cause your device to malfunction or simply stop working. Something similar occurs with the installation of an Advanced Recovery..
In my case, after trying to root my Android Smartphone, my device did not start. It literally stayed on the manufacturer's logo without being able to start. After much research, I understood that my device's firmware probably contained errors or was corrupted. In this case I had no choice but to reinstall the factory firmware of my Android device. This process is what is known as flashing a ROM.
Before continuing with the steps in the tutorial, you should know that each Android device has a different specific ROM that varies depending on the model and manufacturer of the phone or tablet..

The next step will be to download the official ROM of our Android device. You can do this by logging into the following website and selecting the exact manufacturer and model of your device: Android ROM download site . To download the official ROM you will only have to select the link that says: Flash File .

Specifically you will have to open the folder: mt67xx> preloader driver> VCOM> Win7 . Once in this folder you will have to select the file: usb2ser_Win7.inf> usb2ser_Win764.inf depending on whether the version of your operating system is 32 or 64-bit.

The next step will be to check the option: Format all + Download , in the drop-down menu. Remember that this will completely remove all the content from your Android device to install the new ROM. When everything is ready it will be time to click on the Download button at the top of the window.
The process will not start until we connect our Android device to our Windows 10 computer. Remember that if your phone or tables has a manually replaceable battery, it is advisable that you connect your device without a battery. Once our Android is connected to the computer through the USB cable, it will be recognized by the program and the whole process will begin.
At this point you should under no circumstances touch anything on the phone and on the computer. The process can take several minutes, so don't despair. After this time the process will end and you will be notified that everything has gone correctly. Now you only have to disconnect the Android device from your computer for line followed by connecting the battery again and check how the phone now starts correctly with the factory ROM.
