Is it possible to run two ROMs on single Smartphone?

           Sometimes we want to run two operating systems on single computer. Most of the times we want Windows OS and Linux OS together. Simply we dual boot them and use it. But is it possible to run two different operating systems on single smartphone? Lets Dual Boot Smartphone.

Why two OS on Smartphone?

            We want something new every time. Similarly in case of smartphone we get boared using same user interface and features every time. So we try to install different launchers, different apps to get new feel. But it makes system laggy. So we did not get that special feelings of New smartphones.
                 Now we go with Custom ROM designed for your smartphones. But there is another difficulty, Custom ROM has some Bugs. Which restrict us to use it fully. For example in MIUI 8 custom ROM, there is biggest bug that, sometimes network becomes offline suddenly. Only way to recover that lost network is to restart your mobile. So you can imagine that custom ROMs are headache to use (not all the times). So what should we do? What will happen, if we dual boot our smartphone? One will original ROM and another will custom ROM. When we need, we will switch the ROMs with single click. Isn’t it great? So lets do it.

Start Dual Booting Smartphone

              What you have to do now is just install app and Run it. After launching Dual Boot Patcher, you will get a pop-up for Root access permission. Allow it. After it will load current ROMs on device. Obviously only one will shown. After that to dual boot, you have to patch Custom ROM that you want to install. But sometimes custom ROMs comes with lot of patches to remove some bugs, So how to apply that patches? I will mention that in next steps
                  Now click on patch ROM, zip file, after that it will ask about id or location, select data slot only from dropdown. Dont disturb other slot by selecting other than data slot.
                    Now it will ask for id, so enter all in small letters without any spaces e.g. mynewrom
Now here new data slot will be created and ROM will get patched. Install that patched ROM from TWRP. After flashing, install Dual Boot Patcher in other ROM also. Using this method you can multi boot your smartphone.
 
#Note: Other ROM you are going to install must have ROOT ACCESS, if not then root it so as to use both ROMs.
 
                   Now in both of the ROMs you can see Two OS in list. Now, If your ROM comes with patches and you want to apply that then follow the same procedure of patching zip, but this time select newly created data slot ( i.e. if you previously given id as mentioned above as mynewrom then newly created data slot will be named as data-slot-mynewrom. But do this with caution sometimes your smartphone may goes in bootloop.
 

Switching of ROM in Dual booted Smartphone

           You can switch the ROM installed simply by clicking on the name in list or install boot UI is settings which will give you a options of ROM when you switch on the Phone. Update Kernels and RAMdisks in Both the ROMs
 
 
 
#CAUTION:  PERFORMANCE MAY BE AFFECTED WHEN YOU DUAL BOOT SMARTPHONE. ANY MISTAKE DURING THE PROCESS CAN SOFT BRICK YOUR SMARTPHONE. I WILL NOT RESPONSIBLE FOR ANY DAMAGE DURING THIS PROCEDURE. USE TWRP RECOVERY ONLY IF YOU HAVE SOME BASIC KNOWLEDGE OF FIRMWARE OF YOUR SMARTPHONE.
