What happens if I install the wrong frimware

[Julian Correa]

What will happen if I install the wrong firmware OS on my phone, e.g. I have the SM-N7505L and try to install the SM-N7505. Will it brick my phone or some functions won't work properly?

It might brick your phone.
If it doesnt, most probably your network will not work as i see only difference between them is one supports LTE. So i assume mostly radio firmware will be different. If you can get the radio firmware from SM-N7505L then you can flash eveything from SM-N7505 and radio image from SM-N7505L
