Its because you didnt explored smart switch properly ..
I have been there with my phone samsung galaxy j5 ... it happened just like yours ... i rooted my phone, forgot to check oem unlock and got the "custom binary blocked by frp lock" .. then i went to odin and flashed my firmware .. and it turns out .. the firmware i flashed is not the firmware of my phone .. so i got the message "an error occured while updating blah blah please go to smart switch blah blah blah " but i fixed it so theres solution for that ... smart switch
You said smart switch cant read your device?? Its because its bricked theres no way it can be read ..
So all you have to do:
1. Open smart switch
2. Go to "more"
3. Then go to "emergency software recovery and initialization"
5. Then go to "device initialization"
6.Put your model number and then your S/N or serial number .. it is found in the back of your edge plus.. it starts with letter R..
7.. after that .. you wait .. it will download the files for your phone...
That way you wont be flashing ramdom firmwares .. your phones firmware will be flashed since smart switch used the serial number.. i hope this helps..
EDIT: Problem solved!!!
I used this tutorial: https://forum.xda-developers.com/sa...very-samsung-sm-a510f-fd-exynos7580-t3314399/ to install TWRP and root my SM-A510FD on 6.0.1 . My device was rooted and working perfectly until stupid me decided to turn off "OEM Unlock" and i restarted my phone and now it says "custom binary blocked by frp lock" The only thing i can do is go to the Download mode. I tried to use Samsung Kies and Smart Switch when in Download mode but they tell me that my device is not supported. But Odin detects my device and says "Added!!". I am currently downloading the stock firmware for my device from Sammobile and i plan to flash it using Odin.
- Will putting the firmware file in the AP section of odin and clicking start work to fix the problem? (I do not care if i will loose data)
- If this will not work is there anything else that i can do? I can't take it to repair because Knox is tripped and i do not have my receipt. If my phone is bricked forever please tell me so i don't waste my time trying to fix it.
Thank you so much in advance! Any help would be extremely appreciated!!

Just flash stock firmware and you are good to go, if it wont boot turn it off, reboot to recovery(stock) and wipe data & factory reset, later you can again flash twrp and root but dont turn off OEM unlock.

What about when my j7 says custom binary blocked by frp lock(boot.img) secure fail:kernel. It will boot into recovery, and download. Factory wipe does nothing, so recovery mode is useless to me at the moment. my computer detects the phone enough to say Unknown USB device (Device Descriptor Request Failed) driver error as the label of the phone. No matter what mode I'm in. Drivers are up to date, odins good, usb port, computer, and data cords are all good. I've flashed other phones and hooked this one up to another pc to see that it says the same thing. How do I get the computer and/or odin to agree with my phone enough to pick it up as a good device?
Hello, i got Frp lock text, tried going to download mode and flashing a stock firmware, when my phone goes halfway throught it restarts and goes into download mode, now it messed up my boot and stuff and it only shows that "An error has occured while updating the device software.
Use the emergency recovery function in the smart switch pc software.
I can't flash it, it keeps rebooting, please help, thank you.
Use kies 3 and under tools select "software upgrade" put in your serial number and model then follow the steps it should work.
Make sure you don't grab or touch the phone when connected to pc because Odin is finicky like that.
Im having unique issue with my s 7edge.
I cant boot the phone it says Custom binary blocked by frp lock.
I cant access recovery mode it says Recovery is not seandroid enforcing.
I can access download mode but its not connecting to any pc, kies, odin. The download screen says FRP lock: ON, Secure Download: Enabled.
So there is no way to flash the phone or access recovery or boot the phone.
What is the solution, im stuck.?
FYI: I have searched all over the internet for hours but I couldn't found same issue.
Try using Samsung Smartswitch for emergency recovery

Hi sir,
Thank you for the swift replay. However I went through the guide and tried so much thinks to connect my phone to the smart switch but with no luck.
When I connect the cable the PC is not detecting and and no windows sounds for cable connecting. Tried other phone with same cable and the windows could detect it. Tried on other PC and s7edge is not detected by window also. I tried reinstall the drivers by smart switch and not detecting. I have rebooted my PC without luck also. I have tried all the combinations you can imagine but nothing makes the phone detected by PC.
In my download mode screen in my phone shows the following
ODIN MODE
DOWNLOAD SPEED: FAST
PRODUCT NAME: SM-G935F
CURRENT BINARY: Custom
SYSTEM STATUS: Custom
FRP LOCK: ON
Secured Download: Enabled
WARRANTY VOID: 1 (0x020c)
RP SWREV: B:1 K:0 S:0
There is something in the phone is locked and not allowing to connect to any USB PC.

i see the real problem is not connecting to pc then...
try:
updating drivers with this : http://developer.samsung.com/technical-doc/view.do?v=T000000117
Try:
manually deleting the drivers all together in windows and then plugging in your S7 while it is in Download Mode
Try:
unplugging all your USB in devices connectd to your pc (apart from keyboard/mouse) and then trying again
Try:
Using a different Cable (preferably the original one that came with the phone, this is the most common cause)

I tried with all cables including the original not detecting s7.
Generally there is no issue with PC to connect to mobile phones it connect perfectly with my other phones. Even the yesterday s7 was connected to my PC until I triggered the security and the phone stuck in the boot screen. The issue is in the s7 when its locked by (FRP Lock because of custom binary) its not allowing to connect to any PC. Something related to the phone security here.

When you are trying to use samsung switch emergency recovery feature, it is a stand alone part of the program which does not require you to connect to smart switch.
It should see the phone and fix the problem. FRP happened to me and smart switch emergency recovery was able to fix it. As long as the phone can be accessed it can be fixed.
All you need is the model name and your serial number which should be posted on the back of your phone or maybe the box you have still have it.

I have gone through that path, the phone cable unplugged initially. Then I selected more>emergency software recovery and initialization>
two tabs are there, 1- Emergency software recovery, 2- Device initialization.
1- Emergency software recovery: there is no update failed in the list, also I dont have recovery code for the same. no use of this option
2- Device initialization: I have entered the model and SN correctly and it found the stock software, I selected OK for the warning dialog until it reached the stage asking to put the s7 in the download mode, I did that with phone plugged in by USB. I waited forever for the "OK" button to be active, its grayed out because the s7 is not detected at all. So I am in the same loop again, the phone locking all the USB connections.

leave the phone with the screen showing the FRP lock, plug the cable in and use smart switch device initialization.
It should start without asking you to put it in without going to download mode. If it asks that, just unplug and replug the usb to the phone, that usually lets smart switch to bypass that request.

here is something odd and not as all people see it, when I turn the phone power on it start with samsung welcome screen with red sentence in top "Custom binary blocked by FRP Lock" the screen stays on for 5 seconds then the phone goes off.
If I do the same thing with USB cable plugged in with phone off, its automatically power on with charging screen with red sentence on top "Custom binary blocked by FRP Lock" and then the phone goes off and restart the same thing in infinity loop. So when I tried what you said in smart switch to install the firmware it didnt do anything, no installation started, no bypass FRP, the phone still looping on off, OK button grey.
I am reaching to no clue after all your guidance and help. I think the USB port is damaged and not reading data, only charging.

Can you tell me the resolution of this problem in your case? I have the same problem, although I haven't gotten word back from the seller who may or may not have the serial number, so I haven't been able to even try Smart Switch at all.

I had taken it to shop and replaced the whole motherboard in my case. That fixed my problem, yours better luck than me you only need serial number.

I was able to use Odin to reset my phone, after downloading the correct firmware from SamMobile. It took me a very long time to download, as my wireless connection is through my phone, and my household was over 60GB this month.
But I got it done, and have a working S7 Edge again. Sorry that you apparently had a hardware issue, but at least you got it working again.

So, this has been giving me lots of trouble. The phone is locked with FRP. (By the way I am a complete noob). I tried to flash(root? what is it called?) the phone with CF-Auto-Root but it gave me a "Custom Binary(RECOVERY) Blocked By FRP Lock" in the Odin mode. I tried flashing with TWRP also and I got the same thing. I obviously cannot access the phone to remove the "OEM protection", which is apparently the fix. Also, excuse me if I'm going about this the wrong way and there is a much simpler method of removing the FRP from my phone. Thanks
Download the Smart Swtich and connect phone with USB
Make sure all samsung USB drivers are installed
Then start SS and press MORE button and select Emergency Software Recovery wait about 1Hour Maybe less to firmware download and the phone will boot but u need to enter your gmail and password to acess it
Press Thanks if it works
Cheers
