So a mate of mine found an A5 recently without any identification on it. Thought he might as well keep it himself else it'll just be useless.
Problem is the phone's stuck in the initial setup so he asked me to unlock it. My plan was to install TWRP, wipe everything completely and flash the firmware again. I can't get to the settings to access the OEM unlock though. Is there any way to unlock the bootloader and/or get TWRP on there so I can completely wipe the phone?
Same situation here... How did it turned out?
Does anyone know if it is possible to re-lock the bootloader on the Galaxy Tab A T510? If so, would I begin with flashing back to stock firmware then disabling OEM unlock in developer options or following different steps? I certainly want to avoid bricking the device. I've searched for a solution but can't seem to find anything. Thanks!

You need to download the latest stock firmware either from Samsung or Sammobile and use Odin to flash it. DO NOT DISABLE OEM!!!! That has nothing to do with locking the bootloader. Flashing the stock ROM will do that. The OEM enable only disables the FRP lock which makes you login with the same google account used BEFORE a factory reset. If you are sure you know that account login and password, the FRP lock isn't a problem.
edit: The problem with the FRP lock is that people will often create a new google account login and password when first setting up their tablet. And because you only have to do that once, they tend to forget one or the other. Then, if they do a factory reset without the OEM enabled, they are locked out of the tablet.
Thanks for the detailed information and clarification. Your help is much appreciated!
The T510 doesn't have a locked bootloader.

No, but it does "lock" the tablet from getting OTA updates.
I have reflashed the stock firmware however I'm still receiving the following message during boot..."The bootloader is unlocked and the software on this device cannot be verified". Is there a way to remove this message? I am planning to return the device and I want to reset everything. Thanks!
Hi Guys,
I have a couple T580 tablets for my kids, and we had just gotten a new one for Christmas that I set up. I THOUGHT I had done everything correctly, but the new tablet is giving me the FRP Lock suddenly.
Any idea how that could happen? Is there any way to recover the tablet or do I have to do a original rom flash?
Thanks

Somethings not right. You don't "suddenly get an FRP lock". An FRP lock occurs only after you "factory reset" the tablet and don't know the google account login. And that is only if you hadn't enabled "OEM" in "Developer options". What makes you think it is the "FRP lock"? And if it is locked, flashing a ROM with Odin won't help. You'll still need the google account info to access the tablet.

Because this is what it says when I start the tablet...

I have a google account, and info, for the tablet. Not sure how I put it in when the boot process is blocked though...
My only thought is something happened with Magisk?

Again, unless something has changed, which I doubt, that is not the way the FRP lock works. First of all, you said nothing about having a custom ROM installed. But even if you did, the FRP lock would NOT prevent the tablet from booting. It would merely ask for your google account info when it did boot. Have you tried booting into recovery and performing a factory reset?
edit: Let me explain what FRP means. In early versions of Android, if your phone/tablet were lost or stolen, anyone could bypass your "screen lock" simply by booting into recovery mode and perfoming a Factory Reset. So Google came up with the Factory Reset Prevention lock. So if someone tried to use the Factory Reset, the lock would demand the google account login and password to access the tablet. So if you wanted to sell your tablet, you either had to enable "Developer options" and then use that to "Enable OEM", prior to reseting the tablet or put in a google account whose info you could pass to the buyer, remove your real account, and then reset.
In any case, the tablet did NOT show the message you are getting. I've bought several T580s on eBay that WERE locked, and none of them gave that message. A locked tablet would still let you install stock ROMs with Odin, but the tablet would still ask for the google account info. But the way around that can be found in this forum.

I dont think I do, its stock rom, but Magisk is installed which I believe is not a custom rom.

When I turn on the power, the screen comes on, and then says "Custom Binary blocked by FRP Lock" then the screen turns off. I have not tried a factory reset because I was hoping to find a solution without losing everything before I did something that could not be undone.
The only thing left is, I know samsung will (if detected) attempt to remove software. I wonder if it somehow tried to reset automatically and in so doing caused this.
A factory reset does not help in your case.
First option is: contact your person, who sell the phone. Because he must unlock this one in his Google settings.
The question is: how many times a wrong oe no account was insert, that the device doesn't start up till the possibility to insert the correct account.

You don't lose everything with a Factory Reset and what you do lose should be easily recovered from your google account backup. And nothing else could be done that wouldn't also cause a reset.

No one sold me this phone, I bought it new. There is no unlock option. The phone doesnt event start booting, the screen turns on says the FRP lock, then turns off.
Ab FRP Lock said, that the phone is looked via a Google account.
In a normal case, you can only unlock the device, if you insert the correct Account with password.
I don't know.. maybe you have insert 3 time wrong credentials... why the device give your not the possibility to unlock the device.
Try an complete wipe / factory reset out of the recovery menu, so that the OS can start.
The lock isn't away, but maybe you have the possibility to insert the correct data.
In Download Mode here is what I see:

Alright I just flashed the latest rom and that fixed it.
I now know a little bit about what is going on. When I got the tablet, I set it up for me. Then I discovered googles "family link" so I set it up again for my daughter.
Child accounts have FRP protection. I dont know what triggered it, but somehow it activated recently when it discovered magisk which I had installed some time back.
Now I am super irritated and over Family Link...
First of all Hello everyone, my phone version is SM-N950F and CSC XXV
I disabled OEM by accident, now i have that message on my phone, so i tried flashing it with ODIN and an updated version of my phone, but i keep getting Fails no matter the firmware i use, for example "sboot.bin fail", can anyone help me ?
It's probably too late now, but for anyone with the same problem samsung has a protection so that if somebody steals your phone and your bootloader is unlocked they can't just flash a custom fw to use the phone. FRP lock is simply a lock activated whenever you have a google account linked with the phone so to disable it just remove the google account, or reset the phone, but be sure to do it from within android and not from the recovery.
Is it poss to get passed Google Verify lock as I've got a g950f from my late mothers but don't know any of deets for log ins. Can't access setting to allow ADB either
factory reset .... but you'll lose all data .....
Factory reset doesn't remove the frp lock
Okay, we removed a frp-lock once by using Odin. The best you can do is search for the right stock Rom and flash this with Odin, but you need to access download-mode on your phone which must be possible also with a phone with frp-lock, because it is there where the frp-lock is shown. For as far as I know, also recovery-mode should normally still be available.
