Custom Binary blocked by FRP Lock?

Can someone please advise what causes this FRP lock?
Heres what happened.
I have a S6 Edge+
I bought a new S6 Edge+ dual sim
I took the sim out of my old phone and setup the new phone
After setting it all up I switched off my old phone
When I switched it back on, it came up with this error and turns itself off straight away
On the old phone I NEVER rooted or flashed any roms (custom or official)
Would enabling OEM unlock avoid this?
The phone is with Samsung now and their repairers want to charge me half the cost of the phone to replace the main PBA because they say the warranty is void!
Don't do it its a rip off I've just restored my Galaxy S6 edge plus after trying to root it with little success as the root programs aren't very stable at this point. Any ways my phone got bricked in "Custom Binary block by FRIDAY Lock" mode straight out of the box and I did some research and discovered that flashing the Original firmware via Odin restored it to perfect working order with the exception of Knox switch ed on and the Samsung pay app rendered non functional. You can download the firmware at Sammobile.com for free or faster download pay there cheapest subscription, which is what I did.
I have escalated it to the Samsung managers to try and get the fee waived.
If they wont then Ill just take the phone back and see if I can flash the right rom.
What I dont understand is why it locked in the first place.....I have never flashed any custom roms or rooted that phone.

What did you do to cause this though? Did you root or flash custom rom?
I also had this issue. I rooted my device successfully but afterwards I turned off oem unlock and rebooted my phone. This resulted in the frp lock issue. Flashing the stock firmware via odin got rid of it.

downgrading problem oreo to nougat s8

hello,
i managed to get the phone back to get in download mode. stock everything, no root whatsoever. my goal is to root my phone and i have experience doing so but i guess i was just unlucky this time.
i tried searching allover the internet for a fix, searching xda etc.
first off: my device is running oreo 8.0 and it's type is G950FX.
I want to downgrade to 7.0 because FRP lock is on, i did turn on oem lock before starting however i am unable to log in to my old google account connected to my phone.
when i try to flash any bootloader i get SW REV CHECK FAIL DEVICE 2, BINARY 1. i tried almost any trick in the book like downloading 7.0 from sammobile, flashing using odin.
the things i run into when flashing are:
1.can't flash the bootloader, probably because of frp lock.
2. when i don't flash the bootloader for 7.0 i get dm-verity error 0x2.
3. when i only flash 8.0 oreo pda & csc and then flash 7.0 pda on top i do get to boot but i get encryption interrupted error.
4. i am able to boot in 8.0 but can't get past the frp.
i'm out of answers, i really hope anyone can help me out of this situation as i want to use my phone.
Help is much appreciated!
edit: i tried flashing multiple versions of android 7.0 but i keep getting sw rev check fail bootloader device 2 binary 1
i basicly want to do this, a downgrade: https://forums.androidcentral.com/s...s8-plus/878062-how-downgrade-oreo-nougat.html
the problem is i didn't sign out of google or samsung accounts before resetting to factory
You can't. You have a new bootloader v2.
A simple search gives you this answer, if you have u2 and CRED bootloader installed you are stuck. No way to go back anymore.
i'm on u2 and CRED bootloader. i did search for this indeed but i didn't want to give up.
do you think there will be ever be a way to get back into my phone again?
If you have FRP lock good luck. I haven't seen a way yet.
I know it's been 5 months and you've probably either gotten rid of the phone or it's sitting in a dusty bin somewhere, but have you tried Galaxy Reaper? It's a pretty legit FRP bypass tool.
Edit: Scratch that. It's apparently been patched since I last knew it to work. Just wanted to double check, and sure enough..

Samsung Galaxy S7 Edge FRP Locked&SW REV. check fail Device:4, Binary:3

Hey guys, I recently tried to root my phone, went kinda wrong --> my phone got stuck in boot loop. I had to root it correctly to make it work again. Now, I wanted to buy something online but I couldn't bcs that came with the root or something? I got the notification to switch on OEM and something else with USB so, I did, without knowing to turn it off again. After a few weeks, visited another country but didn't got signal and stuff so I thought it would help if I'd put my phone off and back on. Y'all be facepalming right now, for sure. And yeah, I shouldn't have tried to root it in the first place because I had almost no knowledge about any of this so please spare me. Well, as you all know probably, I got the message that my FRP is locked so I tried to unlock it, using forums like these ones and others. They all said the same things but somehow they don't work with me. I downloaded a few Odin version because they all got stuck in SetupConnection or failed. I have downloaded the stock firmware and did everything I should (I think).
I downloaded this firmware:
"https://updato.com/firmware-archive-select-model/?record=9A306FC2821911E9951FFA163EE8F90B" (I can't post links yet because I'm a new user)
Like I said, I downloaded a few Odin version because I read somewhere that if your device has Android 8.0.0 or higher, your Odin had to be Odin3_v3.13 or higher. So I did, I downloaded 2 higher versions (Odin3_v3.13.1 and Odin3_v3.13.3) but also Odin3_v3.12.3. I tried my firmware on all of them but it keeps saying "FAIL", I know that's because it's not the right firmware but idk which other it could be then...
Also, does that new message I've got have impact on certain things? "SW REV. CHECK FAIL (BOOTLOADER) DEVICE: 4, BINARY: 3
I've spend hours and hours searching for a solution but there's always something in my way. And yes, I downloaded the Samsung USB driver and stuff, I tried the Samsung Switch method but the app doesn't 'support this device'. I've seen guys with the same problem getting send from one link to another to download things, I'm willing to delete all I've already downloaded before if it just works... I feel like apologizing for doing stuff I didn't know much about. Please let me know if I explained something poorly, my head is just everywhere it shouldn't be right now. Thanks in advance.

Samsung S8-SM-G950F custom binary blocked by FRP lock

Samsung S8-SM-G950F custom binary blocked by FRP locked, i saw so many theards about this and i read them, and i still don't know what to do, so my question is if i download firmware with "SamFirm" and then use oddin will i get my phone unlocked from that ? As i had custom rom for year and half and today i got that error for the 1st time , also if the "SamFirm" is not good for that can someone give me link for firmware for my phone as updato and all other sites download soo slow at 15 kb/s and i can't use them it will take 20hours to download that (
Similar situation, I broke my S8 screen, so never got it fixed, and was recently without a laptop, so thought id use the S8 thru Dex, it all worked no probs, however, I used to unlock bootloaders to install custom firmware and os's but didnt think id done it on my S8 as it was still under warranty, so upon looking in the developer options, i saw that OEM Unlock was on, so i switched it off, not remembering rooting the phone, now i get same error it bootloops and says custom binary frp lock. Did u ever get yours sorted? I know my google account to login 2 it if i ever get the official rom back working, but trying odin and smartswitch restore im still stuck, just keeps failing, saying frp lock. Cant even get into recovefry mode to factory reset, didnt thiunk i had TWRP installed on it, but i must have. Anyway, if anyone can pls help me pls contact me here or at dcillusionz at proton dot me. Thanks.
PS - I tried downloading from SamFW and using Odin, but FAILED. Hoping u had some luck?

I think i screwed myself (Galaxy S8 Root)

Hey i couldnt find anything else so i hope this isnt a duplicate,
im somewhat of a noob when it comes to rooting but i know a little bit
Today i rooted my Galaxy s8 , everything whet smooth and without a problem,
but then for some reason i deactivated the OEM unlock and rebooted my phone.
Obviously that locked me out of my phone, after trying to flash my phone with the stock firmware that i downloded through samfirm
i got the error sw rev check fail bootloader device 5 binary 4 and i couldnt get that to work.
My next step was to try the Samsung smart switch emergency recovery, which failed.
I got the error that my device was not supported.
After that my S8 also stared showing me a blueish screen with the message : "An error has occurred while updating the device software....",
i can still access downlod mode tho
At this point i really dont know what to do and i should really be in bed because its 2 in the morning .
I really hope someone can help me out here, thanks in advance and a good night for now.

Device 5 binary 4 means you are flashing lower version of firmware than what is on your phone. Samsung will let you downgrade ( bootloader ) versions numbers.
You will need to flash a bootloader 5 or higher to fix.
Note: Don't relock oem in developer option.

Thanks for your reply!
That's what I found out too but I couldn't find a "higher" bootloader, I would have thought that if I download it through SamFirm it should have the proper BL
Do you have any recommendations on where to download the proper bootloader?
Yea that was a big f**k up haha
I just tried to get Poke Go to run but it wouldn't let me login because it detected that the Device was rooted I guess and after changing my device fingerprint and adding PokeGo to MagiskHide and still not being able to login I followed some FAQ blindly Wich recommended to turn off OEM unlock, and other things to hide the hardware site or the root, thinking about it again it should have been super obvious that this is a stupid idea, but you are always smarter afterwards right? Haha

Wow I feel stupid, I'm flashing the stock through Odin right now as I type this, I've downloaded 2 firmwares first one was a random one from online second one was the SamFirm , after realizing the first didnt work I must have deleted the samfirm variant by accident, I redownloaded it and now it's working , but thanks for replying!
