If you are new to the Android ecosystem then let me tell you, stock ROM as the name suggests is the stock or pre-installed firmware which comes with the device. The firmware is developed by the manufacturer for a specific device. So you can’t flash any Stock ROM on your Android device. Every device’s Stock ROM is different. They may be based on Google’s same Android source code but they are different. There are reasons why users need to flash the Stock Firmware or ROM on their device. With time users end up downloading hundreds and hundreds of apps which makes the device slow and if they user downloads any wrong app from play store or other unknown sources then the app may slow down the device. The common thing to do in that case is to remove those bad apps but sometimes this doesn’t work and the only thing which a user can do is flashing back the Stock Firmware and restore the device to factory settings.

- Security: These ROM’s are developed by big companies and hence there are fewer chances of malware/ virus affecting the phone.
- Warranty: Installing a Custom ROM needs root access and this voids warranty of your smartphone in most cases. A lot of OEM’s do not allow the root access or customization.
- Pre-installed apps and features: A lot of these ROM’s come with pre-installed apps which are sometimes useful. These apps vary between different manufacturers and even for models. Some OEM’s also give their customers premium features like Launchers, wallpapers, home screen, etc.
