It’s a headache when you want to flash a brand new ROM, and you have to say goodbye to your current one and do all the process of wiping the cache and installing the new one. And if there’re bugs in the newly installed ROM, then again repeat that tedious process and go back to the stock one.
However, this overhead can be reduced to a great extent, if you have the MultiROM manager installed on your handset, which makes switching between multiple ROMs an immediate task. You can select between various ROMs at the time of boot; thus now you don’t have to get rid of your old ROM, saving you a lot of time.
Now before you get into the MultiROM setup, your device should have an Unlocked bootloader, it must be rooted, and also you need a custom recovery such as TWRP or CWM. Next, your handset should have at least 70% or more battery in reserve for this process.
Lastly, it is advisable to take a complete backup of your data, just in case of things don’t go according to the plan and if you might end up losing your data, as there’s always a risk involved in such tasks.
