Hi all,
A friend with this device (the 4G one) got a forgotten lock screen somehow. I wanted to help bypass without losing data.
The lock screen only keeps asking for repeating entering the pin, it does not provide alternative such as google account (which we do have).
Please note the device is unrooted and I don't intend to root it or do any customization.
Help is appreciated.
Does your friend have a Samsung account? If so, you can use that to remotely unlock it from here: http://findmymobile.samsung.com/

I've always run ADB commands to rooted devices so I'm not sure if this will work but anyways here's a link that might be helpful.

Thank you but I already hard resetted and lost data as the owner chosen that. But I need to research this to a maximum as I found that my Nexus 4 with Lolipop also has this problem (and Nexus apparantly has no Samsung account ) . So if I get the lock screen forgotten, I'm in really big trouble! All expert advice is welcome please.
I'm rooted via ODIN with TWRP. I got a browser hijacker that put my browser home page to some stupid ad, so I tried to get rid of it using the AVG antivirus program. That program recommended I disable "developer mode" on my phone ... and like a total idiot I followed their instructions.
Next time I tried to boot ... I get the "Custom Binary blocked by FRP Lock" message.
I am on vacation and I REALLY need my phone. I can't believe Samsung can just lock me out of my own phone like this. I can get into download mode. Do I try to reflash with Odin or what?
ANY help would be greatly appreciated ...
EDIT: forgot to mention I was on Nougat stock ...

No one is willing to advise me on this ... ?
Odin back to stock seems to be the only way forward? At the same android os level or higher?
flash back stock firmware and next time never disable oem unlock in developer options on rooted phone

You need to call T-Mobile and request that they help you because this FRP lock deals with stolen phones, which I'm not accusing you of. Just saying.. If you Odin back it's going to ask for the original Google account info and password and if you have that just enter it into the phone and then you'll be able to get back into the phone to enable it again. But if you don't have the Google account and password, that's a problem.

I just finished doing exactly as you describe when I checked back here to see if anyone had responded. So even though I had successfully reflashed my phone before I saw your advice, I still appreciate you're willingness to help and the fact that your solution is the correct one.
I've been rooting my phones for years and had never heard of the developer mode warning or run into FRP lock before. I won't forget either now, though.
In case anyone else runs into this issue:
I found my exact stock tmobile rom on sammoble ( sign up, use free download mode, takes forever but it is free) and downloaded the tar/mdf file.
Used Odin3 v3.11, select AP then find your tar/mdf file.
Put phone into download mode and when Odin recognizes it, hit start.
I thought it looped at the tmobile logo but it just took a while so be patient.
Not only do I have a fully working phone again, but contrary to what I had read--that the only way to defeat the FRP lock would entail losing all my data--I lost NOTHING. My phone is EXACTLY the way it was before, including the fact that Developer mode is now enabled AGAIN. How is that possible? I don't know, but I'm very very happy that all I lost was time.
you only lost root, flashing same version explains that you didn't lost your data

When I Odin'ed back it didn't ask me for anything--my phone was exactly the way it was before.
Phone is not stolen. I bought it used off craigslist and had the seller meet me at a tmobile store to verify that it was clean before I bought it. I
This happened while I was on vacation and I really, REALLY needed a working phone. Called samsung and the first rep I spoke to in India--as soon as she heard "FRP Lock," she basically said: "You're ****ed." She also said it was my fault that I had a crippled phone because I never should have rooted it in the first place. When I argued that the root hadn't crippled my phone,--I'd been using it rooted for months with no issues--but that the FRP lock had crippled it, she said FRP lock wasn't Samsung's fault, but Google's fault, and if I needed a solution to FRP lock, I should talk to Google. Classic buck-passing mode. Like Google would have helped me.
Second rep I spoke to was much more helpful, even though she couldn't really help me. She eventually suggested I get the IMEI from tmobile, then send my phone into Samsung and they would fix it--at my cost, presumably.
Thanks to the power invested in me by the internet, however, I didn't have to find out what would have happened if I'd sent my phone to Samsung.
Happy, happy day, and good luck to anyone who runs into this issue in the future!

What I meant by Odin back was you can get back into the phone and just re-enable the OEM unlock in developer settings and you won't have to worry about the FRP crap again.. And you're right I highly doubt Google would have given a crap and gave you the run around again.
I got S7 SM-G930L with a port Rom from S8 (https://forum.xda-developers.com/s7-edge/development/rom-s8-port-s7-s7-edge-ambasadii-t3619548). When I power on the phone I get a message: Custom binary blocked by FRP Lock.
I would like to get rid of the FRP Lock without losing my data.
I saw a video https://www.youtube.com/watch?v=VdAhu45UPsU According to the comments 40% lost their data and 60% didn't.
Could you please advise how to make sure that my data won't be lost?

But how do I boot my phone? Now I'm getting a red message: Custom binary blocked by FRP Lock and the phone is not booting past that. It will not even let me in TWRP.

reflash the stock fw using odin
Not sure
I was said that because I'm using a port of S8 on S7, after I'll reflash stock ROM the data might be lost due to differences of memory formats.
Is it true?

If you haven't backed up your data, it will be lost.
When you get yourself back out of this mess, don't touch that OEM unlock toggle again...

Firstly I have a question regarding the OEM unlock as I just came out of the FRP Lock. Do I turn on OEM unlock or does it have to be turned off? Last time I had this FRP Lock was a year ago though did it again(the mistake with the OEM unlock) as I had forgotten it(Lots of grey hair)
Just don't know if it has to be on or off?
Secondly I have managed to come out of it(so far , hopefully) without wiping data with this guide

To unlock your device by frp lock you must flash the stock firmware when you are in bootloader mode you see custom binary blocked by frp,if you try to flash a random firmware(always of your device) the operation may not be a good end and device say an error with this:
Knumber) Snumber) Bnumber)
When you go to download the stock firmware you must see the "code" Of the firmware with write the same S or B number

Guys, I'm scared to death on letting my phone reboot, I have been told to never let my phone restart unless my google account has been removed, can someone please explain how this FRP block really works?
Am I at risk at every given point of phone restart for real?

It stops someone stealing your phone, wiping it, installing new firmware and using it as if it was new. If you know the gmail and password you put on the phone to access the play store then you just need to re-enter it after the phone restarts. FRP will only kick in if you have flashed new firmware to the phone.
I have a new firmware flashed on the phone.
And I'm using a new gmail with is, not some one July bro used on it.
What am I to do now? I have developer settings OEM unlock toggled on already.

I'm not sure what you mean. If you have a Google account on the phone that you know the email and password to, then just reboot the phone. FRP lock will only activate if you flash new firmware to the phone without removing the Google account first.
Your device should only have 1 Google account registered on the device which let's you access Play store etc. If there is more than one, you need to delete the ones you don't know the email and password to.
Okay...
Oh, okay, now I am getting the rationale.
Albeit, when I flashed in the new custom firmware, it started give me the undo changes by restarting your phone notification, like it did the first time ever that I got the lock. I didn't click it, activated an app that discarded the notification rather.
Now it makes me doubt if I had really removed my mail before flashing the phone.
hey

Yeah you've messed it up by not signing out of account before unistalling xposed. When you say 3 different rom's do you mean stock or custom?
Even in this state you should be able to flash a stock rom to the device with Odin and it will ask you to type the google email and password after boot.
Always turn off FRP lock before modifying the phone, it's a really annoying feature.
I bought a second-hand galaxy S10e that was advertised as being stuck on a boot loop. I fixed the boot loop by flashing with a stock firmware, but was greeted with an frp lock that I triggered in the process. I contacted the seller about it, but he said he bought it second hand himself and has no way of contacting the original owner. I've tried a couple things and thought this through, and I decided to ask here whether I missed anything.
First, is it possible to read the google email associated with the frp lock from the device in order to contact the last logged in owner? that would make this a lot easier if I could ask them to unlock it for me.
I assume this isn't possible, since I couldn't find anything about it. what are my other options? while recovering from the boot loop, I flashed a very recent firmware, so all of the 'frp bypass' tricks I see advertised don't work. I also wasn't able to flash a combination file.
Does anyone have any experience with this, and any ideas I could still try? Bought the phone for my wife, and I'd hate to see her angry :|

not really no, unless it's running on a Mediatek SoC (I doubt it and can't be bothered to check)
or there's a serious vulnerability overlooked by the Android devs in both Samsung and Google, you're out of luck
unless of course there's an exploit in the BROM of the SoC, but at this point you're all out of luck since I doubt you'd be able to avoid a softbrick at best and a hardbrick most likely
also I think you CAN unlock the bootloader (OEM unlocking under DevOpts) by giving all your personal data to samsung and google over the span of a week: login to your google and samsung accounts, have a simcard in at all times and be connected to a single wifi accesspoint so that Samsung is absolutely sure of who and where you are
Ok thanks sir

well... I don't know of any BROM exploits for the Exynos chipset and if you don't want to give away your personal data to Samsung and Google, you probably don't have a way to root your device

can you send me the link for DevOpts please?
DevOpts is shorthand for Developer Options, on anything past kitkat you get to them by 7 taps on the device build model under device information (every OEM has it placed in a different place) and then going to the developer options screen in the settings (also different for OEMs)
a quick online search should provide you with detailed steps for your device
