Downgrading from Nougat - Sprint Samsung Galaxy S7 Edge Questions & Answers

Hi so I'm running the latest ota on stock firmware and I'm wanting to try the unlocked firmware however the only one available is marshmallow which I'm fine with using for a couple weeks or so until Nougat is released. The question is can I downgrade to Marshmallow by flashing the appropriate files in Odin? If so does my sim need to be unlocked to flash? Thank you so much have been looking for answers but no luck.

The SIM doesn't have to be unlocked first as long as it's the Sprint Sim. I did just that recently - downgraded from the Nougat 935p to mm 935U.

Not familiar with your model, but I am pretty sure that if you flash stock MM in Odin you'll lose root anyway. You can of course root later.

Nexus 6p ota updates

Hi guys I'm currently using nexus 6p android 7.0 nbd90x latest security patch. Previously rooted with twrp installation. Now returned back fully to stock. Even locked the bootloader. Did it using the nexus root toolkit.
My ques is that will i be able to download and install ota updates like I used to before rooting my phone. Thanks
Yes as long as it's full stock u will receive and install OTA updates.
This also works with Full Stock with unlocked bootloader's.

SMG935A Branded to Unbranded Firmware

I have ATT branded firmware on my phone. Is there a way to make it unbranded because I feel like ATT is going to delay a update for MM (Nougat OTA Update) It is also unlocked with branded in it. I need replies! Please help!
You can flash the 935U firmware if desired. However in my opinion and experience running it, definitely has slower update support then AT&T.
The 935f has a different processor then the US carriers and 935U version and you cannot flash them.

I have already flashed T-Mobile firmware. It works good. Thank you.

T-Mobile has faster update, that's why I went for it.

Odin to stock question

I have a 900V still running rooted KitKat. I decide to upgrade to MM and lose the root. There are 3 stock firmware on Samsung-Firmware.org. DO I Odin them one by one (from PD1 -> PF4 -> PG2) or just the most recent version (PG2) alone? All of them are tar.md5 files. Thank you in advance!
Use Samsung kies 3 it will update your phone to latest firmware pg2 for you
