Flashing a custom ROM on an Android device can provide you with the latest features and updates, even if the manufacturer has stopped supporting the device. However, it's important to note that the process of flashing a custom ROM carries some risks, and it may void your warranty or potentially brick your device if not done correctly. Proceed at your own risk, and make sure to backup your data before proceeding.

Here are the general steps to flash a custom ROM on an Android device:

Check device compatibility: Ensure that there is an available custom ROM compatible with your MLS phone model. You can search for custom ROMs specifically developed for your device model on popular Android development forums and websites such as XDA Developers (https://forum.xda-developers.com/).

Unlock bootloader: Most Android devices require an unlocked bootloader to flash custom ROMs. Unlocking the bootloader will wipe your device, so ensure you have backed up your data. Instructions for unlocking the bootloader can vary depending on the device, but you can typically find the instructions on the manufacturer's website or Android development forums.

Install custom recovery: Custom recovery software such as TWRP (Team Win Recovery Project) is necessary to install the custom ROM. Download the appropriate TWRP recovery image for your MLS phone model from the TWRP website (https://twrp.me/Devices/) or other trusted sources.

Enable USB debugging: On your MLS phone, go to "Settings," then "About phone," and tap on the "Build number" several times until it shows "You are now a developer." Go back to the main Settings screen, select "Developer options," and enable "USB debugging."

Connect your phone to your computer: Use a USB cable to connect your phone to a computer with the necessary software installed.

Transfer the custom ROM: Download the custom ROM file for your MLS phone model from a trusted source. Connect your phone to the computer and copy the custom ROM file to the phone's internal storage or external SD card.

Boot into recovery mode: Power off your MLS phone. Then, boot into recovery mode by pressing and holding the appropriate key combination for your device. This combination is specific to each device but commonly involves holding the power button and volume down button simultaneously. You can search online for the specific key combination for your MLS phone model.

Install the custom ROM: In recovery mode, select "Install" or "Install from SD card" (the exact wording may vary), and navigate to the directory where you copied the custom ROM file. Select the custom ROM file and confirm the installation.

Wipe cache and data: After the ROM installation is complete, it's recommended to perform a "wipe cache" and a "wipe data/factory reset" to ensure a clean installation. These options are typically available in the recovery mode menu.

Reboot your device: Once the wiping process is complete, select "Reboot system now" to reboot your MLS phone.

Please note that the exact steps and terminology may differ based on your MLS phone model and the custom ROM you choose. Always refer to the specific instructions provided by the ROM developer and the Android development community for your device.

Remember to proceed with caution, as flashing a custom ROM carries risks, and ensure you have a backup of your important data before starting the process.

You can also simply run a beefed up version of your existing os,but do make sure that you choose the right Roms.

A "clean flash" refers to updating a ROM after wiping system partitions like the vendor, data, internal storage, and others.
