I believe you get that error if you try to flash an older ROM once you are on 4.3 or newer.
They probably meant 4.4.2, the Odin flashable version of this can be found at http://www.sammobile.com/firmwares/database/SCH-I535/ Unfortunately I don't know if this will be your solution or not, hopefully it is.

You may be trying to flash a version 1 bootloader over a version 2. You can't roll back to an earlier version. Get the latest sprint firmware and it should work fine. If that's not it, I don't know what to tell you.
Yes that was it , i fixed it yesterday , thanks though

Downgrade SM-G955U1 to nougat pains...

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

[URGENT] Error SW CHECK CHECK FAIL: [aboot] Fused 5> Binary 1

Hello everyone !
I have a serious problem on my cell phone and I am desperate to solve it, I am even willing to reward for help (I mean it).
I have a Galaxy S8 (SM-G950U1 SnapDragon), I bought it at BestBuy Mobile and unfortunately do not know which carrier it is.
I was trying to do Root in it, but it was giving failure, it appeared the following message:
Error SW CHECK CHECK FAIL: [aboot] Fused 5> Binary 1
From what I understand I'm trying to flash an AP / PDA / Firmware in a different version, but how can I find out which version to download the correct firmware?
Thank you !!!

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.
