Hello.
I have a Sprint Galaxy S6 Edge [G925P] that I'm trying to downgrade from 6.1.1 to 5.1.1, but every time I try to flash 5.1.1 from Odin, my S6 gives me the "SW Rev Check Error. Device 3 Binary 1" (at the download mode).
Does anybody knows why, and how can I fix it?
I have a SM-G955U1 I'm trying to downgrade to Nougat since Oreo totally borked the bluetooth in both my cars (both BMW's - audio connects ~50% of the time, phone book no longer transfers).
I'm failing to flash G955U1UES2AQL1 with Prince Cosmey Odin v3.12. The error I keep receiving is:
SW REV CHECK FAIL : [abl]Fused 3 > Binary 2
I've also tried to flash G955USQS2BRB1.
A quick Google says it's because I'm trying to downgrade versions, but doesn't this model have an unlocked bootloader?
What am I doing wrong? Any guidance is greatly appreciated.
What version are you currently on?
Just my guess is that your on v3 not a v2 bootloader hint the error. The secure bootloader is saying it's a 3 and the firmware binary is saying I'm a 2. Since they dont match no go. Same if you tried to flash a 1 you would probably see Fused 3 > Binary 1

Hello wise people of XDA,
This is my first post.
I currently use an S6 G920F United Kindom unlocked as my phone and i have been using this phone for a long time. Now its past its warranty I decided to root the phone and see what i can do with it and get rid of the bloatware. Normally i either use KingoRoot or KingRoot but both failed so I searched around on the internet and came across CF Auto Root. After seeing it was successful for others i jumped on the bandwagon. I rooted it and everything was golden until i came across a problem, it would randomly turn off. This was random and infrequent. but not it happens like 5 times a day so i decided to flash a stock rom. For some strange reason Sam mobile wont let me download a stock Rom so after poking around the internet i have download a few stock roms however they always fail in Odin. Now my phone wont even boot as it says "error occured while updating use smart switch emergency recovery feature" so i go onto the Smart switch PC app and then it doesnt recognise. After 2 days of trying i haven't had any luck so I don't know what to so. Every time I try flashing something, when it fails i get some red text on the phone which I don't understand.
Someone please help me as I cant just buy a new phone and this is the only phone i have got. Any help would be very grateful and please don't hesitate to ask any questions.
Edit:
It says on the Download Screen:
Odin Mode
Product Name: SM-G920F
Current Binary: Custom
System Status: Custom
Reactivation Lock: Off
Secure Download: Enabled
Knox Warranty Woid : 1 (0x0500)
RP SWREV: B:6 K:2 S:2
(When it fails it says) SW REV. Check Fail. Device:6 . Binary: 5
Hopefully that helped.
Somewhere in the middle of the firmware version there's either S5 or U5, on the firmware you are trying to flash. On the phone either S6 or U6 is installed, and there's downgrade prevention. You need firmware with S6 or U6. By S6 I don't mean the phone, it is just a version code.
Generally look for the firmware meant for the phone's region, though on websites the displayed region might be incorrect.
If the cellular fails change the firmware or wipe data (not efs!!!!!).

What do I do? I have like 10 different "stock roms" claiming to be United Kindgom BTU at Android 7.0 but all are failing. And I do not know what you mean by S5/6 and U5/6. And now i get a different error message. When it fails it now says Binary: 1. I don't know what to do!
Thanks for the quick reply and appreciate the help.

The firmware version(s) look like this,
G920FXXU6ERF5 . If there is U6 on the device and the U5 is flashed, it won't work. There are a few firmware 'components' inside the zip or whatever, and all of these must have the same or a higher version in the middle. New firmware might require odin 3.13.1 but should not show this error.

U6/S6, "Device:6" is in the odin log so it's already 6 and won't return to 5.
I've been trying to root my Galaxy s7 - G930P, but it fails every time,
OEM unlock is set to true, USB debugging enabled, PC whitelisted. //not sure if that last one matters
Device information:
samsung/heroqltespr,
android: 8.0.0,
firmware: R16NW/G930PVPSBCTA1
Snapdragon
I've followed a few tutorials, First I tried https://bit.ly/3fXMHwa (The original link was censored for some reason.), but it failed. No error in odin.
The second was https://forum.xda-developers.com/galaxy-s7/how-to/samsung-galaxy-s7-sm-g930p-root-xposed-t3502829, Also a fail. This time the error was something like FAIL! (auth) I've got a snip for this one https://cdn.discordapp.com/attachments/710567590342426684/712349332757544991/unknown.png
Both times there's been an error on the phone, SW REV CHECK FAIL : Fused 11 > Binary 1
Is there any kind of documentation for odin errors?
ADB drivers & environment are properly installed, odin run as administrator when I use it, I removed google accounts on the device, I think I saw somewhere google accounts might interfere with flashing.
I also tried flashing TWRP , but the error was 'secure check fail : recovery'
My friends and I don't know what to do, any suggestions? I can't flash any firmware other than current.
I was able to flash my current firmware.
I can't think if I missed anything, Alexa#9029 is my discord tag if anything more is needed.

The failure "Rev Check Fail" means the root file your trying to flash is for a much earlier version of the firmware which no longer works.
You need to find a root method which works on Version 11 of the firmware. Fused=firmware version on the phone, Binary=firmware/root version your trying to use. You cannot flash firmware or root which is older than which is already on the device.
It a pain in the ass I'm afraid. The S7 is an older phone and developers have moved on creating roots for the newer phones.
Thanks
Is there any way to root? I don't really care how complex or difficult, I just want root access. If not is there a way to change boot animation without root?
Thanks for the information though, now I at least understand what the error means. For some reason I can't find any docs on errors.
Any idea why flashing twrp won't work? Is it because it's also old?
I forgot to mention this in the original post:

Error when flashing TWRP heroqltechn I picked this one because I know my devices is not Exynos,
PROCESSOR Type - Qualcomm Snapdragon 820
GPU - Adreno 530
dude s7 qualcomm models cant be rooted because of qualcomm secure boot and no one has made to break it
I also have the same cell phone SAMSUNG GALAXY S7 MODEL: G930P, ANDROID 8.0 OREO, FIRMWARE: G930PVPSBCTA1, I am also interested in having root access.
Does someone has the stock firmware for the SM-G930P? I'm stuck with a bricked one I think, It had a G930V rom installed, so I managed to reinstall it once and it got working for a week but with random reboots, and then it got stuck on bootloop till today, I've tried a lot of SM-G930P rom variants without luck, they install correctly but when it reboots, it says "recovery booting" and it never boots... I only know it is binary version 11, if i try to install any other binary version it will give me error..

This error means your are flashing older firmware than what is on your phone. You will need bootloader version 8 or higher. It will be the 5th number from the right of the firmware name.
market version devices (consumer devices) aren't meant to be flashed backwards... it's set so that only the technicians/engineers working on the device can do that. You'd have to know how to unlock that security feature for you to flash backwards on your own.
