BOOTLOADER AND MODEM FOR J5 2015
All files have been extracted from the official firmware (Samsung Galaxy J5 2015)
The idea is to make it easier to go back to an earlier version or vice versa
It will not be necessary to install all the complete firmware, so you can flash a ROM based on (xx version android)

Hi everyone, I'm new to this. I have 6.0.1 on my J5FN and I'd like to install Slim 7 Nougat, but I read that I need to downgrade to 5.1 first before I can do that. Can anyone write me a quick guide on how to do that, because right now I'm reading things which I don't understand very well. Cheers!

Download the 5.1 files corresponding to your model to flash in odin as BL, first the BL and then the modem finally the recovery and you are ready to install the ROM of your preference. I hope and have explained.
@By Zonik, I am in doubt if the MM modem is compatible with the LP boot

Okay, thank you. So I download the 5.1 firmware by Samsung, flash that and then the MM modem from this thread, and then the ROM of preference?

    Good luck, thanks to this tutorial, Luisfelipee got MultiRom from Ganesh to work over mm bootloader and I've tested all nougat ROMs and some lollipop ROMs without downgrading. Give it a chance, it will not brick your device, just make a nandroid backup first. Good luck buddy!
