Inside supersu You have the option, but I prefer reinstall stock firmware. If you read more you can optimize your root phone.

The option is only to delete the supersu. I've done that, now I don't have superSU, yet all the root checkers i've tried still say that my phone is rooted.

I just installed SuperSU from the Play Store; it asked for an update, and I clicked on "normal" My device then rebooted and now it won't even start. I wiped the cash data and reset the device to factory settings and it won't start again. All I get is the "Galaxy Edge+" logo with 'custom binary was blocked by FAP' and 'kernel is not seanorid enforced' highlighted in yellow! I'm freaking out here! Did I just bricked my phone?

You enable OEM Block in developer options? If don't boot, you have to install all firmware again.

I've disabled the OEM Block after rooting it. I'm downloading the firmware right now. would that fix it? or do I need to do something else?

I've done that already, and my phone is running just fine now. Although I didn't download the firmware from sammobile, and I got it from android-updates.com, which is slightly different, and contains apps and games pre-installed in it. Thanks a lot for your suggestion, and I promise I'll keep that mind. After all, I'm just starting to use android, and this is my first "failed" attempt as aneeded android user. I got to admit that I didn't face such complicated problems with iOS ?
Forgot to activate OEM-Unlock for Root. Phone Bricked: "Custom binary blocked by FRP"
Hello,
today i rooted my J5 (SM-J500FN) via Odin and CF-Auto-Root.
Everyting went well but after the root i unticked OEM-Lock (please dont ask me why i did it) and restarted my phone and this nice screen greeted me: "Custom binary blocked by FRP. SECURE FAIL: KERNEL"
So I tried everything I found on the Web and found nothing really helpful. Then i tried flashing the recovery and reflashing CF-Auto-Root but both got blocked in the Download Mode with the message "FRP Block".
Please can someone help me, i really hope i dont have to reset my phone because my google authenticator is stored on it, and it would be a real pain to write to the support of every account i connected to reset my Security Options.
Thanks, Toby
P.S: when i flash the boot.img does it wipe my device?

Try using Smart Switch from Samsung to backup you stuff and accounts. Maybe it will work. Using Smart Switch you can also easily reflash the latest Marshmallow firmware.

I don't know about that... Try asking someine more experienced.
I do know that even in Recovery mode the ROM locks you out and doesn't let you factory reset for example

No it does not. You are not affecting the data partition.
This would only happen if you flashed the factory repair firmware.
Thank you all. Here is my Guide: https://forum.xda-developers.com/android/general/complete-guide-to-rid-custom-binary-t3541403

Happy for you ^^
When activating the oem unlock you can install Twrp, kernel or custom rom without the activation of FRP security that is activated when you establish a security pattern in the device
When the binary is blocked by the FRP you must install the factory firmware, then enter the recovery and do a factory reset since the FRP prevents external access to the system and data as prevention
You will be prompted for the email and password of the previously used account

You only need to enter your login details if you factory reset.
Flashing the stock firmware is enough to remove frp. No need to factory reset.

Which device? Don't you know your Google login details?
I've been trying almost everything for days. When I turn on the phone the bootloader enters in a loop.
I can't access to recovery (vol up + power), not even in update mode(vol up & vol down + power).
The only thing I can access is the fastboot but my phone is locked and I don't the have the imei to unlock via calculator or the oficial huawei page.
If someone have any suggestions.

If getting your IMEI is your only concern then you can get that from the box... But you'll need Product ID too, and for that you'll need to have your phone booted up...

I downloaded the official ROM from huawei and is the recent version but when I tried to install it with "fastboot update file.zip" is asking for an android-text.txt and I been searching to re-create that file manually and then is asking for another file and so on.
I've been searching if I can install the oficcial ROM by fastboot even if is not unlocked and find this guide but it is not usefull for me 'cause I can't access into the download mode or use adb.
This is the information I could extract from my phone.
Firmware : ALE-L21C109B130
I couldn't fint this version of firmware.
If you could light my way if you have another method.

Ok i searched for ways to find an IMEI number and found couple of ways...
1) Look under/in the sim tray. It may be there (I didn't check this out)
2) Find the IMEI/MEID using Google Dashboard. This is Google's control center that can be accessed from any computer with a web browser. You will need to log in with the Google account associated with your Android phone.You can access Google Dashboard by visiting www.google.com/settings/dashboard Expand the "Android" section by clicking the "Android" heading.Locate your phone in the list. If you have multiple devices associated with your account, all of the devices will be displayed. Find the device that you are trying to retrieve the IMEI/MEID number for. (This works)
3) At last, you can try to remove the back case and remove the battery. This can help you in 2 ways. Firstly, there should be IMEI code present under the battery. Secondly, this may cause you to get out of bootloop

Instead of putting "unknown" files to your system, rather flash stock system image via fastboot. This way you'll have surely unmodded file with correct permissions.

I managed to lock odin install with a program called surelock. they give me access to knox options. in there i can lock hard reset and download mode. After doing that i try to flash the last pie version but i get the error FRP blocked the download in red letters.
Now the phone is completely secured!
Don't know/cant find a way that works to bypass the frp lock on recovery and on odin.
I think my phone is finally safe from thieves right now. If it get's stolen it will be useless for him/her.
is there any other way to bypass this security measures that i adopt?

Now the only way to unlock a phone with those security measures is with a box to change de boot chip.
