At first, I'd like to thank all participants and developers for making this forum possible! I am still absolutely excited about the stuff which is offered and discussed here.
Having said this, I hope I don't get flamed for the following silly question:
I am confused about the FRP on Samsung phones in general and especially the Galaxy S5 (G900F) and would be grateful if somebody could explain what circumstances exactly activate the FRP. I have read many threads, especially on this forum, about how to circumvent the FRP on the Galaxy S5 (after accidentally having flashed and not knowing the Samsung account credentials). But I haven't found a thread which explains exactly when FRP gets activated.
Currently, I do not have a problem with FRP. But I really want to avoid that I have such a problem one day. For certain reasons, I just have bought two brand new Galaxy S5 (G990F, DBT version without branding / lock), one for my wife and one for me.
I did flash LineageOS 14.1 (current version as per the time of writing this) on both phones. I did not create a Google or Samsung account yet, so FRP can't be active yet (as far as I have understood).
One of my understanding problems is that some forum threads / tutorials / posts state that FRP gets activated if there is a Google account, and that others state that it must be a Samsung account. Again, others state that it must be Google / Samsung account together with an active fingerprint or unlock pattern (if this is the right term - I am not a native English speaker). This is very worrying, hence the questions:
- Under LineageOS 14.1 on the G900F, can FRP get active at all?
- If yes, what are the exact circumstances / combinations of conditions which activate it?
- Finally, is there a way to disable it in the first place, i.e. before a Google / Samsung account is created, or before any of the condition combinations which could activate it occurs? In other words, is it possible to globally disable it so that it can't be enabled any more? I would have no problem with rooting, if that would be necessary to achieve that goal. My wife is fantastic, but I won't guarantee that she does not create a Google or Samsung account, does disable the FRP after doing so, or does write down the credentials after doing so
Thank you very much for any explanations ...
Galaxy S5 does not use FRP, it uses Reactivation Lock.
The first refers to Google account, the second - to Samsung account.
RL does not activate by itself, only if you turn it on in the settings.
Some used phones are sold with a kind of RL "bypass" and RL may be activated if you reflash such phone.
But RL can be completely turned off on S5 in a relatively easy way that's why I don's see a cause for concern.
P.S. Are you a virus?
@bbsc Thank you very much for taking the time!
You state that I can turn off RL easily. Do I need a stock ROM to do so? In LineageOS 14.1, I did not find the respective setting, probably because LineageOS does not know about Samsung oddities. Did I miss something?
P.S. No, I am not a virus. Al least, I hope so. Actually, I don't know exactly what I am, and, if anything, how many of them or how much of it.
Joking apart: I am always using random strings as my user name (if it is this why you asked ).

Solely for elaborating what @bbsc has also correctly stated, Here's just a little/brief definition of both...
~ Google FRP (Factory Reset Protection): This is intended for those who may have had (unfortunately) their device lost or stolen and the FRP is there to prevent others from activating your device if they had reset the device to factory settings without the true owners permission. Only someone with your Google account information can use/activate the device.
~ Samsung Reactivation Lock: This is also intended for those who may have had (unfortunately) their device lost or stolen and this security option is tasked to prevent others from activating your device. Once the owner decides to activate this option, this feature will demand the individual to enter the Samsung account credentials for the true owner (the one who had activated this option) after the device was factory reset.
There's more to it but, I believe that this covers the basics of them both as well as the differences between the two.
I hope that I had explained this okay via text...
Good Luck!

I don't state YOU can turn it off easily.
I state it CAN be turned off relatively easily. You may want to have a look at my thread about RL on SM-G900V (locked bootloader). It's not you case, but yours is easier.
You can try, of course.
First, look if it really is turned ON. It's clearly seen on the display in Odin (download) mode.
It it's ON and you do know the credentials then just flash any stock firmware and you will be asked these credentials when following Samsung Startup Wizard.
If it's ON and you do NOT know the credentials then flash an early 4.4.2 firmware, bypass Samsung Startup Wizard with one of the known tricks and login to ANY Samsung Account. You will be able to turn RL OFF after this.
P.S. Thank you for the explanation about random char string .
@Ibuprophen Thanks for the explanation ...
BTW, you have LOS installed and this means a custom recovery installed too.
RL blocks custom recovery flashing, so your phone should have RL turned OFF.

I see. Then we had a misunderstanding. I have assumed that you were relating to some way to disable RL *before* it has been triggered since this is what I had been interested in, i.e. some setting in the OS like: "In the future, prevent all users from activating RL".
But I have now understood that you were relating to how to repair the phone when the RL already is active. When doing my homework (i.e. before asking here), I already had read several threads about that ... it does not seem to be complicated. Fortunately, I don't need to do this.
Coming back to my "problem": Thank you very much for the tip that the status is visible in the download mode. On my phones, it clearly states that it is not active. I had expected that because otherwise I would have had problems with installing TWRP and LineageOS.
But there are still questions left:
Just to be sure: I have understood the difference between FRP and RL, but I am not sure if the situation with the stock ROM is the same as with LineageOS. Could somebody please clarify?
In other words, if I use nothing else than LineageOS in the future, can I be sure that nor RL nor FRP will trigger one day given the fact that RL is currently not active?
In other words again, I have understood that the phone does not use FRP with the stock ROM. But LineageOS is more Google than Samsung, hence I am worried if FRP possibly could be triggered from within LineageOS. Could that be possible?

When reactivation lock is enabled, after factory reset you need to enter your Samsung account's password to use the phone.
Settings-->Security-->Reactivation lock
Also (not sure if it's a feature, or I just did something wrong), with reactivation lock enabled I wasn't able to flash any custom ROM/recovery with Odin.
That is indeed what it does, I think it's a great feature.
With this option enabled: people will not be able to use your phone if it gets stolen.
(Of course until one finds out how to exploit it, and gain access.)
Along with that, you probably have more change to track it down while the thief makes attempts to unlock it.
(Or when the pawnshop who tries to sell it to will power the device on.)
Sadly this does not protect the device from its battery being pulled and the parts sold separately.
(Wish they would find a solution to this one, for example let a phone, phone home the serial numbers when new hardware is detected.)
Sadly I'm not sure when rooted this feature is still functional, it's the only reason holding me back from rooting, maybe someone can try?
Kind regards, Stefan.
I use avast antitheft .. it will survive a master reset and willl let you control the phone , track it, etc....

I'm rooted and have reactivation lock enabled. Apparently everything is working properly but until now didn't did a hard reset so I could not tell if it's gonna work.
i've read similar problems with other users who sought help from the meizu-flyme websites but they won't respond with anything better than a canny reply that they will be looking into it. it's been months since this problem popped up and its amazing that nobody finds anything that specifically addresses this particular product. someone suggested that it is the manufacturer that can provide a valid and lasting solution to this by providing the source code of the os. but even so, i am just a curious cat daring to get killed or be delivered by its boldness. i just can't believe that it is so difficult to gain access to my m2 note again even as it keeps me from doing so and still receive phone calls from it and let me listen to my music with it. No modifications were made to it except perhaps getting root access but I am not sure if debugging was activated before i was shut out from getting in due to this flyme lockscreen pattern that id completely forgotten! i did try the new security flaw that's just been discovered wherein you try to put in a very long string when making an emergency call with it. But when i get to the next step in using the camera, it just won't show the notification shade where i can proceed with what is expected to be done to crash or hang the unit! there is a factory mode that i can boot into but i find no suggestions on what i can do from there. in fact i can even upgrade it successfully (i can watch it go through the process) and it would later inform me that it was successfully done but still the pattern lock would still be there! before it locked me out i managed to link it to my wifi so it is actually online but i don't know how good that is if it could solve my problem at all.
Specifically the SM-J327P, which is on 6.0.1 and presumably some recent version of Samsung's shell... What I'm wondering is, are some of the methods discussed in sources like this one (methods 3 and later, as I'm assuming the bootloader on this phone is locked) still viable?
It's almost impossible to find reliable information via Googling because there are so many "ad-vertorials" with this subject; lots of ads masquerading as tutorials, in which case the exploits they use may not even work. The Google problem is compounded by the fact that there are so many keyword results that deal with bypassing the lock screen via "legitimate" methods, like simply resetting the phone or using Google/Samsung authentication to bypass...
What I'm trying to figure out (even hypothetically) is if the methodology I linked earlier in the post is still viable, considering the J3 Emerge's bootloader, Samsung shell and Android version.
Bonus points if you can go beyond that, and tell me if bypassing PIN unlock for this phone is even possible, without losing the user data. Also, brute-forcing a simple 4-digit PIN code isn't possible anymore with Android, is it? It will lock out after X failed attempts, requiring Google auth, right?
Thanks.
Hi all,
Today Morning, I have lost my Oneplus 5. Is there any single way to track my phone ?
And also tell me the ways to erase all my personal data in the phone. I have tried to track using Google's Find My Phone. But its not useful since phone has been switched off.
Details:
Device was decrypted
Synced with gmail account
Bootloader unlocked
If phone is switched off there is no way to track it.

Sorry to hear that! Unfortunately, Android Device Manager is not as feature rich as compared to the other third party alternatives, and hence what you want might not be possible with Google's Find My Phone. That's precisely the reason I use Cerberus anti theft in case anything like this happens. Although in my opinion, anyone who knows how to Google can get into your phone since it is bootloader unlocked and the device is decrypted. So no matter what app you use, those two things will defeat any and every possible safeguard.
My brother passed away and was using this phone until a couple of weeks ago. I don't have the lockscreen pattern but I'm trying to do a little detective work regarding my brothers last activity. I reached out to law enforcement, but they don't have an active investigation and they suggested that I reach out to his cell provider [Tracfone] which I might try. Of specific interest to me is his text message activity on the day of his death.
Anyhow I scoured the net and tried to beat the lockscreen via emergency dialer, and also tried to connect via adb shell and MTP. I also don't think the device was registered via the samsung tools. I'm at the point where the device told me I have 9 unlock attempts left and it will erase the device after. The lockscreen seems to appear at device power and I think that it might not have booted android completely at this point.
Is anybody aware of a method to bypass the lockscreen which would work on this device so I can look into the details surrounding his death?
Sort of desperate here. There seems to be some software called Dr Fone that claims to have a lockscreen removal. However not sure that it works and on this device.
I may have a solution for this if you are wanting to preserve data if not check around on youtube for a video on FRP resetting this. I might have wrote a tutorial on this somewhere but I cant remember atm. Basically if you don't want to preserve the devices data (your brothers as you say) then you will simply factory reset it and then follow an FRP Removal tutorial you can find on here and or youtube.
btw nice leet username =]

If you're still around, I have an old J327t1 that I had dropped and broke the screen on a few years ago. I recently fixed it, but can't remember PIN. I would like to preserve the data and am interested in what you have

All you need to do is find a recovery for that and flash it then go into the lock files and remove those. You can find some guides here on XDA or on youtube.
This was before I got into development, so adb isn't enabled, bootloader is still locked, and the phone is not rooted, so I'm skeptical I'd be able to flash. It's also running (I believe) Marshmallow, and most of those "find and delete lock settings" methods were for 4.x Kit-Kat and below. I could be wrong though.
If you have a particular thread in your watch list, I'd be grateful for the link.
I've been all over looking for a solution, hence me posting in here as opposed to creating a thread. Didn't want to reinvent the wheel if I didn't have to.
Despite the above limitations, the device has not received any updates since June 2017, it DOES go into MTP mode when I hook it to my laptop, and I have verified that it is vulnerable to the Mtpwn exploit.

Also, I turned a moto g7 Play into a Nethunter device and had tried Android PIN Bruteforce, but after entering in so many PINs it would make me wait 30 seconds to try again and I couldn't figure out how to get my g7 to keep the screen of the J3 on. Or wake it back up, since it requires you to hit power then swipe the screen.
I ended up wiping it because it had Pie and no workaround for the wifi throttling, and installed Q. It's rooted, but I haven't set up nethunter back up on it yet. I do have an S5 that I has Nethunter, but haven't set it up with HID support yet. Plus, the battery on that would drain too quickly to use for this process.
