I’ve been wanting to try out CyanogenMod 12 on my new Note 4 for a while but I didn’t want to lose TouchWiz and all its unique features. Yesterday I found a great way to dual-boot both ROMS and decided to make a guide showing the process.
This would be much easier but at this current moment the Note 4 doesn’t support AROMA installers, thanks to rlorange of XDA for creating an app that makes the process a little more simple for us.
I am using the SM-N910F Snapdragon version of the Note 4, I don’t know if this will work with any other Note 4 variant.
This will require a rooted device.
- Download the latest snapshot release of Dual Boot Patcher from here and install it on your Note 4.
- In Dual Boot Patcher go to ROMS and you will see your primary ROM, press the menu key and click “set kernel”.
Now you need to patch your CyanogenMod ROM and Gapps files to make them compatible with dual-booting.
- In the Dual Boot Patcher app select “patch zip file” and choose “trlte (Samsung Galaxy Note 4)” from the drop down menu, now find the ROM and Gapps files that you’ve download to your device and patch them one by one.
- Now you need to download the app rlorange created from here.
- Run the app once and let it do its thing.
- Copy the patched CyanogenMod.zip to /sdcard/patchmultiboot/dual/<patched zip>.
- Run rloranges’ app again and you should see your zip file appear, click the zip file and wait for it to patch.
- Repeat steps ‘d’ and ‘e’ again with the patched Gapps.zip
- Reboot to recovery and flash both zips from /sdcard/patchmultiboot/patched_files/.
- When your Note 4 reboots you will be in the ROM you just flashed.
- Go into the Dual Boot Patcher app and set the kernel for your second ROM.
- To switch ROMS use the Dual Boot Patcher app.
**If you’re freezing in recovery when trying to flash your patched zips read here**
Some people have reported that rloranges app is not working for them, this means that the AROMA installer is trying to boot resulting in a hard freeze in recovery.
To patch the zips manually follow these steps:
- Unzip the ROM/Gapps
- Navigate to /multiboot/info.prop
- go to the last line and you should see “#mbtool.installer.install-location=chosen_location”
- Remove the “#” at the start of the line so it looks like this “mbtool.installer.install-location=chosen_location”
- Change “chosen_location” at the end of the line to “dual” so it looks like this “mbtool.installer.install-location=dual”
- Rezip the file back up and now it should flash fine.
