Hi,
I am running the Android N firmware on Athene: Custom Rom RR_5.8.0
I was playing around with dual boot, and successfully, but I only tried the 7.0/7.1.1 custom ROMs.
Could I flash MM custom ROM to dual boot, or simply put, can I downgrade to a MM ROM without messing with the N firmware, with and without dualboot on separate occasions or do I need to flash stock MM?
Does it sort of have a backwards compatibility?
What sort of risks will I be looking at?
Thanks in advance, this community is wonderful!

You don't need to flash stock MM.

Theoretically, the ROMs should not have any issue.

From what I've seen, ONE person had some issue with fingerprint recognition on MM after flashing an N ROM. Otherwise, I've encountered nobody who has had issues.

Sure you can, but it will leave modem and bootloader newer versions intact, which is probably good.
And you can always use Odin to flash your Stock Rom back if you find some incompatibility.

Once you have a custom recovery, you can flash anything you want except 4.3 custom ROMs due to incompatible bootloader's boot structure.

There is no common answer for this question, coz
It depends on what custom rom.

When you flash via recovery on the Note 3 it usually will not touch bootloader and modem.
If you flash a Stock Rom using Odin and your phone is also on a stock rom it will update bootloader and modem.
And yes, if you move from 4.3 to 4.4 there is no way back to 4.3. It should not be a concern since all good and actively kept roms are on 4.4.
I have a D801 (Tmobile G2) and I’ve been running CM11 on it for over a year.
Now that we have lollipop, I want to upgrade to a ROM based on the official Lollipop release, (this one: http://forum.xda-developers.com/tmobile-g2/development/rom-tmo-lp-extreme-v1-0-4-16-15-t3084681)
Ofcourse I’m rooted and have a custom recovery installed, specifically ClockworkModv6.0.5.0/Philz Touch 6.48.4)
Can anyone please guide me on how to install the Lollipop ROM mentioned above. I’m thinking the first step would be to update my recovery to a TWRP recovery…. How do I do that?

And then I just flash the Lollipop based rom? Even though I'm on CM11 (kitkat)?

That depends, you might need the latest bootstack for the new CAF-based roms, but not everyone seems to agree. I would flash it anyway though, this would prevent any issues like sound bugs and anything else you might find.

Hey guys, everything I've read has said once you update beyond 4.3 you can never go back down because of knox. I also saw someone mention you actually can downgrade to a custom ROM based on a previous build just not to stock. Can anyone clarify this for me? I'm not worried about breaking my warranty since it's long since expired. I'm on the rooted 5.01 Goldeneye ROM and want to go back to a 4.2 ROM. strictly for tethering purposes
What is the model # for the s4?
It's the AT&T sgh-i337
With a locked bootloader, the phone is limited to customs roms based off a stock Samsung rom. Aosp and cm will not install or run.

Thanks for the reply! So if I stick to TouchWiz based custom roms I can downgrade without bricking my phone?
Yes, just don't touch the bootloader or modem.

Ok thanks. Can you suggest a good 4.2 ROM? Also, since I'm already rooted with safestrap, do I just wipe and flash the new ROM or do I need to install a different version of safestrap and kernal etc? I'm have trouble finding any instructions on how to downgrade. I appreciate all your help!
I can't recommend any 4.2 roms as I don't have the phone. Also, I don't think such an old rom will work on an lp modem and bootloader.

Ok so based on your statement "I don't think such an old rom will work on a lp modem and bootloader," does that mean you actually don't think I can downgrade?
You can try but I don't think you will have a functioning phone in that the imei will not be properly displayed which means the phone wouldn't be able to connect to the carrier.

If any developer has the time, please consider looking into making a cm rom, cause we've managed to get echoe rom working on the Sprint S7.

Idk if it can be done on locked bootloaders that are tw launcher based because Cm is aosp based

True didn't think of that. Hopefully we find a way to bypass that or unlock the bootloader.
The only thing that stops us from having a Cyanogen rom on our phones is our locked bootloaders. It doesn't matter that we have Twiz based OS on our phones cuz when you flash a rom from a custom recovery, it basically writes a whole new OS onto the phone. So whatever OS your running prior to the flash gets overwritten with the new OS.
So the only way we can flash a custom OS is if our bootloaders get unlocked, cuz once that happens we can flash a custom recovery, and from there we can flash whatever rom we want, as long as its made for our phones. First we got to have a working root method, then we have to have our bootloaders unlocked so we can flash a custom recovery, then we can flash away. We have a root method now, so it's only a matter of time until our bootloaders are unlocked. IMO

So wait, I've flashed a custom rom (echoe rom) on the galaxy s7 using flashfire and it works fine, so what would stop Cyanogenmod from working on the Galaxy s7?

That rom is still touchwiz based. Kernel is the same, usually cm/aosp roms use a different kernel or greatly modified kernel.
