Default [Q] How to return in 4.1.2 if needed?


I installed [4.3] [MK4] DN3 (Note 3 Ditto) Electron ROM from Team (E-Team) and I have a question.

I had to install the bootloader MJ5 because I had a problem with wifi connection.

I just wanted to know how to return to 4.1.2 if needed.

I found this but is there another way?

In fact I do not understand from what bootloader on 4.3 it is "impossible" to return to 4.1.2?

Thank you for your help and good evening to all!
