My experience is, that if you want to flash anything to primary rom you don't have to patch it. It's pretty nice feature, bc you have to remember about patching only if you want to install something to non primary rom. And installing anything properly patched won't affect other roms, as Mahatma said. So, if you forget about patching zip, you can be sure it will be installed to primary rom.:)You have to patch it also in primary. And this doesn't affect second one.Dear @Monkteo...thanks for the guide..i now have both S7EV13 and Echosphere V1 installed...just a few questions...if you dont mind please...
I am now on primary rom and wish to flash Sctymod....do so as normal..(via twrp)?
Will that also affect secondary rom?
Thanks in advance
No big deal if you backup your secondary system with the app first.
Off subject, but if anyone is wondering if duelboot will be updated to handle S8's - that is the intent.
