This was a hefty size patch for my S7 Edge Verizon (flashed with U firmware).
It also changed the bootloader from 4 to 8
Good observation! I don't plan to flash/root with anything else, but yes, after this update one have to be aware of the bootloader upgrade.
Oh yes DO NOT flash this unless you want to lose root possibly for good.

Used patched version of odin to flash the samsung unlocked firmware (G955U1) from the firmware servers. No more Verizon Splashscreen and spay/bixby work fine
I've been using android devices all my life and have rooted every single device I've owned in the past (probably 4-5 devices). I know the risks and I know how to flash my device and such but I got my S8+ from verizon about 3 months ago before the international unlocked version was released. I only bought it from verizon because their phones are carrier unlocked by default. I use google's project fi.
Verizon is somewhat good with bloatware I can disable or uninstall all of their applications and I haven't found my device to be slowed or burdened by their addons so I never felt the need to root my device which was nice but I got the Bixby update today and I cannot use it unless I update my system software. Tried to update it and it attempts to connect via verizon and ultimately fails saying it cannot connect to the update server. I expected this -- I think it's due to me not using verizon and not having the phone registered with their service.
Want to use Bixby and also would like to flash a stock updated (latest stock version) ROM as I don't care for any new features or custom ROMs because this phone is perfect as it is so far.
Phone software/model specs:
model is SAMSUNG-SM-G955U
kernel version 4.4.16 march 11th, 2017
sev 8.1
android 7.0
aspv march 1st, 2017
knox 2.8
If I follow my usual rooting route properly is it safe to root my phone? Asking because S8+ root is relatively new. I won't ever sell the phone so I don't care if the warranty goes void or something like that.
Essentially looking to turn my Verizon version into a completely US unlocked phone with a stock clean ROM. Is there any possible way I can perform this and still be able to use Samsung Pay? Not a necessity but I do enjoy it.
No root is out

Alright, If I flash the newest version of the samsung firmware onto my device (force update it) will SPay and Bixby still work? And my Knox will be fine?
Both should be intact and working as far as my knowledge goes Bixby for sure spay shouldn't be affected. Let me get this straight you have a Verizon s8+ flashing the unlocked firmware correct?

I have the S8+ G955U. It's verzion and has the ****ty verzion startup screen and sound it's just annoying. I really want to use Bixby voice as I just got the update from samsung but it says I have to have the newest samsung firmware to use it. I cannot update my phone normally because I don't use verizon I use google fi. So I want to try to flash the standard US carrier unlocked firmware onto my phone from sammobile (not the verizon variant). Is this safe?
the firmware list I'm choosing from: (spaces added so because account is not old enough to post links)
www . sammobile . com/firmwares/galaxy-s8/SM-G955U/
Which one on that list should I use? Obviously I'd choose the first one which is the Verizon firmware but I really would like to just have pure Samsung unlocked stock firmware so I don't have verizon apps & the verizon startup screen.
That's a tough decision I too have a Verizon s8 and it was plagued with the bloat and the splash screen when booting but I used a package disabler to get rid of many if the unwanted and unnecessary packages I didn't like as for using Bixby and getting rid of the splash screen.... It is safe to flash unlocked firmware many people have done this and there is a thread here on xda somewhere all about carrier switching the s8+ to the unlocked firm I could find it if you'd like?

If you could get that thread for me that'd be perfect. Thanks for the help. Really wishing I waited the extra 3 weeks and bought the unlocked version instead.
Updating because I was able to solve it myself. I used a patched version of Odin to bypass the model mismatch error and flashed a new system image and csc (G955U1 model image) that wasn't for my G955U Verizon model.
Bixby works, KNOX is fine, SPay is solid. Verizon splash screen is gone and the phone (from the settings point of view) has no carrier and is fully unlocked and void of bloatware.
I have a regular Sprint S7 (SM-G930P). I just updated to nrd90m.g930pvpu6brd2 and I want to go back to the previous version. Is it possible to do without rooting? Is there a way to root without losing all the data on my phone? I would like to use the version just before the March 2017 security update.
Thank You
You cannot flash lower firmware even with root because your bootloader has been updated, cannot downgrade anymore
Even though they are both 7.0 roms? Has the bootloader been unlocked yet?
Bootloader remains locked for all snapdragon models. You should be able to side step in version, but not go back. Even though it's all still android 7.0, bootloader versions continue to update, so there's several for 7.0.
I figured that. I would like to remove the security patch that messed with mock locations. Thank you
I just went back to Superman V3 to get Wifi calling working again on my Unlocked S7 since im changing carriers to tmobile.
On stock, this phone still gets a ton of updates since its international
The issue is that the Android Security Patch for this rom is From July 1, 2018
Is having a security patch from last july,is this even an Issue?
Is there some method of flashing Security Patches on Samsung Devices that of course are rooted/romd?
Any other suggestions?

My note 8 had OneUI pushed to it about a week ago even though I kept refusing not wanting to while I was sleeping. It says my bootloader is v5. This is actually what it says (N950USQU5DSD3). My problem is that when I search for the firmware I'm wanting to downgrade to (the last oreo update possible for this particular phone) on Sammobile I can't find the one for At&t. I see ones for Verizon, sprint, etc. But nothing for at&t, which one am I supposed to use and where can I get it? This is going to be my very first downgrade/upgrade, really my first time doing anything like it on android. And I CAN do this right? There's nothing I should be aware of that makes what I'm trying to do not able to be done is there? The biggest reason I'm asking is because I have very limited tools to work with, I have a little 12" Acer aspire one (no disk drive) running windows 7 home basic, mobile hotspot from my wife's phone(the last software I tried to download and use came from xda out of a thread I found titled, "Stock Oreo N950USQS5CRF6 Odin*files*for AT&T*NOTE*8" it failed halfway through 2 nights ago during the beginning of storm, and the whole time it would only download around 32kbs so it literally to FOREVER! Only for it to fail halfway through. Was I wasting my time or was this in fact the firmware I'm looking for? If not, as I asked before, where could I find it?? Thanks a bunch for any help.

^^^^^^^Is this all I need? Do I need to follow this tutorial or a different one?? What version of odin, do I need anything else
Sorry for so much all at once, I really hate this update and want Oreo back.

Follow the steps from the above-linked post, and follow them very carefully. I did, and I was able to successfully downgrade from Pie to Oreo on my AT&T NOTE8.
I actually flashed the unlocked firmware, which has zero AT&T bloat. It works just fine for my needs. I don't think AT&T WiFi calling works on this unlocked firmware (I haven't tried - I don't use it).
Caveat emptor: whichever version of Oreo you choose (either the AT&T stock, or the unlocked firmware), we are stuck on the February 2019 Android security patch.
Only Pie gets the latest security patches. As long as you are ok with this, then proceed with the downgrade to Oreo!

A little off topic, but has anyone seen an AT&T security update for May yet? I'm still on April security, and it's basically mid June?
Tha k you I'll check it out when I get off work, I didn't know you could flash the unlocked firmware on a carrier locked phone
Let me get this straight. Can a locked bootloader AT&T SM-N9500U on Android 9, N9500USQU5DSD3 downgrade to Oreo? I thought this bootloader whould not let you go back.
I LOATH Pie and wan to go back to Oreo so bad, please tell me there is a for sure way. This is my first permanently locked bootloader phone and it's killing me not to flash an software I prefer.
I dont know I wish someone could tell me forsure whether it will work or not because now my phone is getting another software update notification so it's getting ready to force another update on me and I doubt after that I will still have bootloader v5. Can someone please verify whether my current bootloader (N9500USQU5DSD3) will downgrade successfully to back to oreo or not? I have the oreo firmware I want to use downloaded and ready to go which is (SM-N950USQU5CRL1). Can I downgrade to this without messing anything up?? Please I need a fast reply I dont want this new update forced to my phone and updating my bootloader to v5 where I can ever go back to oreo.

Yes you CAN downgrade back to Oreo. BUT you MUST go to a bootloader 5 firmware.

Yes you can go to that firmware. You will want to back up and allow it to factory reset. Be sure to use the modified version of Odin. Go HERE, post #2
My employer recently restricted access to Android devices running anything less than SPL 2019-08-05 and since Samsung does not seem to have the ability to deploy patches in a timely manner I'm looking for options.
Is there a way to sideload a security patch?
Is there a custom rom that I can install that won't torch Knox and render my device non-compliant anyway?
Is there a good place to sell my 10e so I can buy a Pixel 3?
1. Getting the patch. If you have the 970U1 or 970F, there is already firmware with the August update released. With the 970F, you might have to get a different country's firmware while the 970U1 seemingly will go to August with a manual update check. If you have a 970U (US carrier model), look into ways to get the U1 firmware loaded (you may need to get sim-unlocked first). None of the carriers are past July.
2. No. Custom roms are only for the 970F and involve rooting and breaking knox.
3. I use swappa. Fees are about $15 at the ~450 USD price point you'd get. You may find the P3 a step down after the S10e

I have 970U1 with the current August patch but it is showing a patch level of August 1, not the Aug 5 mandated by my company's MDM app.
