Hi, as the title said, is there any beginner guide for downgrading to Marshmallow? My S7 Edge is SM-G935FD, Exynos version. I've decided to downgrade it from Nougat because my battery life is horrible after I updated to the latest update. I read several threads that said they encountered problem with the vibrate motor. I don't want that to happen, obviously. Is there any solution to prevent that from happening? Thank you so much.

You can find a marshmallow rom and install it with odin but in my opinion its better to stay with nougat because the security patches and the battery will be better after some charge cycles

Actually it's been months and the battery is still horrible, so, no. And I don't plan on rooting anytime soon because my warranty is still 4-5 months left. But thanks for replying. Do you have other solution?
I am getting Galaxy S7.
So it will be totally new phone. This means that I intend to factory reset and no worries about data loss, new phone. This should make the question easier to answer.
I considered:
Keeping Marshmallow
Updating to Nougat
Updating to new Oreo which is just released to S7
Requirements:
Maximum compatibility with permanent root with no issues
Maximum compatibility with xposed
Maximum compatibility with various xposed modules
Ability to have BLACK everything I want absolutely no white menus anywhere.
I am coming from Kitkat. If I had my way I would keep KitKat, unfortunately KitKat 4.4.2 is not available for S7.
One only real benefit I see besides super slowing down my device on the new versions, is that Nougat and up I believe has a blue light filter integrated? It would be super cool because this is an important feature. Currently I use Twilight blue light overlay, but if I could have a native filter (like f.lux for PC) it would hugely improve my user experience.
Maybe I will like newer features, but maybe not. I usually DISABLE tons of stuff including:
Disable fingerprint
Disable updates
Disable face recognize
etc, I don't want any of that invasive junk.
I also don't use Samsung Pay or any other junk.
I like maximum control over my device and I hate white and have to have all menus black. I did learn some newer versions of android OS actually have theming engines included where I can turn everything black, that will be very great for me. White menus physically hurt my eyes especially at night. It's painful to me and causes red eyes. So I must have all black menus.
I don't want any problems especially not audio or gps etc problems and I never want to enable fine location.
So I wondered if you know which is the best OS to use to meet my requirements with best root and xposed compatibility and no problems. Marshmallow, Nougat, or Oreo and what version?
Additionally, I am also open to any recommended custom ROM, if you have any suggestion.
In further reading of threads I am getting worried. About to cancel my order and get refunded and give up on getting an S7 and just keeping my S5.
The reason I'm getting worried is because I am reading that US versions with Snapdragon processor G930V has a locked bootloader. I am unclear if I can root or not.
Advice would be helpful as I only just ordered and I am about to click cancel order.

From what I have read, you can root a G930V on Marshmallow and Nougat but not on the new Oreo build.
This guide is for Marshmallow:
https://forum.xda-developers.com/ve...-to-notes-root-install-xposed-unroot-t3411039
And I believe this one is for Nougat:
https://forum.xda-developers.com/verizon-galaxy-s7/how-to/how-rooted-s7-nougatand-fixed-lag-t3576393
But no TWRP or typical custom recoveries. Only flashfire and modified stock ROMs. I think I read that Xposed worked on Marshmallow but not Nougat. Not certain on that though.

Well my S5 does have a custom recovery but is on stock rom, got full root when I downgraded to KitKat.
Thanks for letting me know it will probably be the same procedure. I did order it now. Going to try it. Hopefully, it works with full root,
Which OS+root is better, rooted Nougat or rooted Marshmallow (considering potential bugs)?
I think Nougat has a blue light filter built-in, is that right?
It may be a matter of opinion but I am open to hearing your opinions.
I received the phone today. It has this OS version G930VVRS4BRA1 which is 7.0 android I received the phone today. It has this OS version G930VVRS4BRA1
I don't know if I should change the OS or update OS or what or do for sure to be rooted

Yes. It's just not officially released yet. I've been scouring the web for a leak. This means Oreo has been built for our device already and the official release coming. If you're curious about WiFi Alliance, wikipedia has good information about them.

I managed to find the firmware, however, it's behind a pay wall on servers in Iran. The firmware name is J727PVPU4BRH5 if you want to help look for it. As soon as find it on a free server, I'll post an update.

I'm already running Oreo. TWRP has problems with it. I can't make a backup of the OS. You can restore a back up, but you have to flash the BL file from ARG2 then wipe everything in TWRP first. SuperSU 2.82-SR5 will cause a boot loop. I'm going to try magisk 17.1. Honestly, I'm very disappointed with Samsung's Oreo... It's almost the exact same as Nougat, and the new camera sucks, very bad. They gave us Nougat, with Oreo 8.1 as the base firmware. That's my literal take on it. I'm definitely getting a Moto G6 after seeing this, and I'm going back to my stock build.

I have, and flashing back to nougat works fine. You have to flash ARG2 for it to work, and you can't downgrade the Modem. I'll put together instructions and probably a debloated ROM later this evening, and I'll get the firmware uploaded ASAP. Some notes, clearing the camera data fixes the blurry image problem, and it can be rooted. You need the latest TWRP, and Magisk 17.1 stable. You must flash TWRP, swipe to allow modifications, then format data with the option that makes you type "yes", then flash magisk. Root works perfectly. No issues. I'm debloating the OS right now. I'm about to test Viper too. Its actually much faster than Nougat once the junk is out and yes, it can be fully deknoxed. This might not be so bad. I'm still disappointed with their lack of Oreo-esq cosmetics though.

I've got 3 of 4 firmware files uploaded. The AP file is giving me trouble cause my WiFi sucks, and it keeps failing before it finishes. I did put together a full stock Oreo ROM but its got problems. You can only flash it using TWRP if you have the ARG2 bootloader, but, the ARG2 bootloader, won't allow Oreo to boot up no matter what. We'd need a custom boot.img and I can't make one. The ROM can't be flashed with the Oreo bootloader installed either, because it prevents TWRP from copying/writing to the data or system partitions. If it tries to, it'll reboot half way through. Magisk 17.1 will also lose root after awhile. We need a custom boot, or we need a modified root method and an updated TWRP to have any fun with it. SMH at Samsung right now. They gave us Oreo, with no milk, and a slap in the face. Nougat everything, running on Oreo 8.1 firmware... I'll never get over that. I'm running an ARG2 build cause everything works, and largely looks the same. I swear, they didn't even try. They just reskinned some Nougat apps and put them in an Oreo system. I will never buy another Samsung product after seeing this half hearted Oreo they gave us.

Dear Sirs;
Having had to replace my originally bought (Nov 17, 2017) J7 Perx from Boost, then bricking it and replacing it with a Galaxy S6 refurb from Boost, which was then STOLEN by a "friend" of 6(six) years, has been replaced by a NEWER J7 Perx. This device received at lest 3, if not 4 OTA updates, one of which was a supplemental firmware/software update. About Phone (and Samsung INFO app) NOW reveal the following detail:
HARDWARE VERSION; J727P.02
Mfg date; 03/15/2018
Software Version; J727PVPU4BRH5
Android Version; 8.1.0
Samsung Experience; 9.5
Baseband Version; J7272PVPU4BRH5
Build Number; M1AJQ.J727PVPU4BRH5
Android Security Patch; August 1, 2018.
If given instruction and link to necessary utility to extract the firmware from my device to my PC, I would be more than pleased to provide the files(s) procured from that process.
I look forward to hearing more about possible deodexed firmware to ROOT my newest device.
A custom ROM would be nice, too.

Guess I should have browsed a few more posts before posting.
I found the link to all the 8.x firmwares for the various models, and must say "Bravo!" for the Herculean effort expended to collect, upload and make all that available.
Thanks!
Ok so I rooted my Verizon phone 2 years ago and I'm still running 6.0.1 with G935VVRU2APE1, the security patch level is from June 1, 2016, yes I'm wayyy behind. I'd like to go to Nougat or Oreo if possible with a fresh start/data wipe. Not concerned with root atm.
Where do I start? I've read through a lot of forum pages but no one has a build as old as mine it seems. According to updato.com/firmware-archive-select-model?q=SM-G935v (can't post proper link) the latest build for 6.0.1 is G935VVRU4API3. Can I go from APE1 to API3 without issue following "{GUIDE} Flashing the SM-935U firmware onto your Verizon S7 Edge and Rooting" or does it have to be a certain prior version?
From there will an OTA update or an official stock odin file get me to Nougat/Oreo? Thank you in advance!
I did upgrade my 6.0.1 V to 7.0 U. From there I got the OTA updates/upgrades to Oreo. You can get them faster if you use SmartSwitch on PC and phone.

Thanks for the reply. So do I go from my current build to the latest 6.0.1 (API3) or just go straight to the latest 7.0?
I would say you have to go to an official one first, using Odin.
