first, install primary rom normally with all settings (set it like it's the daily-rom)
download and install
-dualboot apk (I will make some mega)
also download dualboot utility
-dualboot utility zip
this app.zip it's in case you can't boot from primary to secondary,or secondary to primary
so you go in recovery and install the zip(the zip will automatically erase after you finish using it)
select from menu to switch to what rom you want and reboot to rom or to recovery
1.in your primary ROM , install the Dual Boot Patcher app
2.Open the app and go to "Roms" in the navigation drawer.
It will ask if you want to set the kernel. Make sure that you do.
(otherwise Open the primary rom and set the current kernel as the primary kernel)
3.Go to "Patch zip file" in the navigation drawer and patch the ROM or zip you want to install.
The app will select your phone model automatic (for S7E and S7Flat it's herolte , I use it)
(if it's needed to patch multiple files make it one by one)with the same name (ex.S7Ev23)
You can select one of the installation locations (my advice for S7E data-slot, and rename it what you want)
In-app flashing
To use in-app flashing, go to "Roms" in the navigation drawer, tap the floating button on the bottom right(red button)
and add the zips you want to install. (it's better to have the patched rom in the root of the SD card)
You can select multiple zips and they will all be flashed in one go.(my advice is to choose to flash 1 by 1)
Once you've added all the zips you want to flash,(if you flash rom and kernel, first flash rom and after kernel)
click the check mark in the action bar and they will be flashed right away.(take your time and relax)
when flash is finished, press back to roms menu (check if secondary rom have a green mark)if yes than it's OK
IMPORTANT;open primary rom and update ramdisk then open secondary rom and update ramdisk (very very important)
then reboot from dualboot menu (the phone will open in secondary rom)
IMPORTANT! : first thing after complete set secondary rom is to install dualboot.app and set kernel for secondary rom
(otherwise you can't switch between roms)
In recovery flashing (the rom with aroma)
after patching the rom,
reboot in recovery and flash from there the patched rom and kernel (if need it) one by one
(it's better to have the patched rom in the root of the SD card)
IMPORTANT; (dont panick) the phone will NOT start in secondary rom so don't reboot ,
you will need to flash utility zip and switch to primary rom for update the ramdisk for primary and secondary rom.
After that you check the secondary rom and reboot from dualboot apk
IMPORTANT;first thing after complete set secondary rom is to install dualboot.app and set kernel for secondary rom
(otherwise you can't switch between roms)
any other questions ? any time !
good luck
