Dual Boot Setup Procedure

I am a newbie to K3 Note and since I successfully did this today itself, I believe I am the perfect guy to explain this.

1. Download the 3 files (one apk and 2 zips) listed under "8.0.0.r2162.gc717564 Wed, 27 Jan 2016 22:40:02 -0500" from here : https://snapshots.noobdev.io/

2. Install the apk on your phone, the Current ROM will become the "Primary ROM".

3. After installation open the apk and allow it to " Set the Kernel".

4. Now to install any other ROM in Dual boot with your primary ROM, first of all decide the location where you want to install it. To know about various locations where you can install secondary ROMS, please go through "Instructions for Dual Booting " in the original thread on xda here http://xdaforums.com/showthread.php?t=2447534

5. Once you have determined the location where you want to install the secondary ROM, you need to patch the secondary ROM zip file so that it installs at that exact location and nowhere else. Patching can be done either from within the app on the Phone or through the exe file on the PC.

6. Patching zip files procedure :

i. On the app : Put the zip file for the new ROM (which you want to install as secondary) on your phone and open the app, swipe right on the left edge, select "Patch Zip File" , add the ROM zip file using the "+" icon on the bottom right, make sure that K50-t5 is the phone and select predetermined location for installation of the secondary ROM as per the glossary in "Instructions for Dual Booting ", then it will confirm the new file name and finally tap the "tick" icon on the top left to patch.

ii. On the PC : Extract "DualBootPatcher-8.0.0.r2162.gc717564-win32.zip", which is one of the 2 zip files downloaded from https://snapshots.noobdev.io/ , open the extracted folder and run "DualBootPatcher.exe" , select the ROM zip file to be installed as secondary, select the phone model properly, and select the location where you want to install as you have determined previously and click on "Start Patching"

7. Once you have obtained the patched zip file from any one of the 2 methods stated in step 6, make sure you have the patched zip file on the internal Storage of your phone. The patched zip file is now ready to be installed. There are again 2 methods to install :

i. From Recovery : Open the recovery and just install the patched zip file normally without wiping anything.

ii. From App : Open the app on your primary ROM. Go to "ROMs" , tap the pink button on bottom right, select the patched zip file, it'll confirm the location for which the file is patched and then confirm the install, it'll take sometime.

8. To flash any zip file whether to Primary or Secondary ROMS in the future after you have setup DualBooting, they need to be patched as per step 4 where location has to be selected as per the location of the ROM to which the zip file is to be flashed. The patched zip file can then be flashed as per Step 7.

9. To switch between ROMs, open the app, go to "ROMs" and select the ROM you want to go to. Once selected, wait until a "tick" icon appears on the ROM and then just reboot your current ROM to boot into your new ROM. Install the app in all your ROMs for switching easily between them. For the app to work your ROMs should be rooted else switching will need to be done through recovery, refer the " How do I...?" section on the Original xda page here : http://xdaforums.com/showthread.php?t=2447534

Cant make it any more simpler than this. I hold no responsibility to anything that happens to your device, I am just stating how I did it for quick reference of any newbies. And Credits to the Original Developers.
