Flash the stock ROM via Kies or download the exact firmware from Sammobile and flash it with Odin. and next time before flashing a custom recovery make sure you enable USB debugging and allow OEM unlock before booting into download mode. and don't forget to Remove both google/samsung accounts
(this will disable FRP lock and prevent blocking custom recovery)

"custom binary blocked by frp lock"

Edit: No one replied with a good answer so i reinstalled stock recovery while keeping root and turned off OEM Unblock and it bricked my device with "custom binary blocked by frp lock" and i am currently fixing it with Smart Switch initialization. Moral of the story: Never disable OEM Unlock
(A5 2016)
Does this happen after you turn off OEM Unlock because the recovery is not stock (TWRP is installed) or because the device is rooted or both?
If after rooting with https://forum.xda-developers.com/sa...overy-samsung-sm-a510f-fd-exynos7580-t3314399 i flash stock recovery and turn off OEM Unlock will i still get this message?
Thanks!
Please note that i had the "custom binary blocked by frp lock" error but i fixed it with Smart Switch initialization. I want to turn off OEM Unlock for security reasons

just flash previous firmware version which u have in your phone before frp lock.
nothing to worry its not bricked.
only ensure version u are going to flash is same as before , flash via odin and enjoy

I already did it, my question is that if i remove TWRP and install the stock recovery while keeping root, will disabling "OEM Unlock" show "custom binary blocked by frp lock"

Help
I am going through a similar enigma. I have S7 Edge. If I log in with Google and then turn down unlock on will I get custom binary error? Any help would be greatly appreciated.

@CrystalGTX
This is an old thread, but I am having the same problem; (stupidly) unchecked OEM Unlock. Reboot, and now I have "Custom binary blocked by FRP lock".
When you say "fixed it with Smart Switch initialization", does that essentially mean reflashing firmware?
And as a result, erasing all data?
I've read that flashing stock firmware can save the hardware, but I'm much more concerned about the data; I need my contacts, photos, txts, etc.
EDIT: Err, shoot. I see now this was posted by a Guest, so I doubt the OP is going to give me a response. Anyone else help?

I DON'T KNOW THE ANSWER... but I have a rooted, unlocked BL, with TWRP on 5.0 OF1 BUILD and here is what it says in the DOWNLOAD MODE.
Odin mode
Product name: Sm-900v
Current Binary: Custom
System Status: Custom
Reactivation Lock: off
Qualcomm Secure Boot: enabled (csb)
Ap Swrev: S1,T1,A1,A4,P1
MODE: Developer
Secure Download: Enable
UDC Start
I think the "MODE: Developer" is the answer if the bootloader is unlocked. BUT AGAIN I DON'T KNOW FOR SURE.
What you can try to find out for yourself is..
1.go to download mode and write down what it says.
2. Root your phone.. then check what it says again.
3. Unlock BL again see what it says.
If it says "Developer" after you unlock bl then it a good assumption that it's ulocked.
Good luck.

Yes, if you see developer mode on the download page... It is bootloader unlocked.

FRP Lock, No System installed, OEM & USB-Debugging off

Hello,
I have a Samsung Galaxy S7 edge ( SM-G935F ) Exynos Version.
I flashed the new Oreo Firmware with Odin. I have also a Samsung Gear 3 and wanted to use SHealth. I rooted the device ( didnt work) .
I set back the OEM setting in the Developer Options and turned off USB-Debugging. After restarting I got an ERROR: Custom binary blocked by FRP Lock.
I deleted my Data : "Wipe data/factory reset" in the Android Recovery
Now my Problem: I cannot flash the Stock Firmware again and i cannot flash TWRP.
So I think i dont have Android and i also dont have enabled the options OEM & USB-Debugging.
Has anyone an Idea what to do?

So you have disabled oem unlock and you can't flash custom rom or recovery due to custom binary blocked by frp error..
Also you can't flash stock rom due to dm verity error if i guessed correctly?
You are badly stuck... maybe follow this thread it may help https://forum.xda-developers.com/galaxy-s7/how-to/guide-onelatest-stock-fw-csc-root-t3702963/
