Hi, five nights ago, my phone just turned off, and then, restart for itself, but whit the "Blocked by FAP lock" message.
This is not the first time that happened this to me, because I forget to enable the OEM unlock, but is the first time that made it out of nowhere. I'm now with Android Lollipop.
That's the reason why I mades backups of my phone every week, but this week don't (I mades it every sunday), and have so important information on my device that I can't lose. In fact, the device is in my desk, I'm without phone since then.
I know that flashing the firmware will recover the phone, but doing that I lose the data.
There's a method that can recover the data first. And then flash the firmware?
Please, is so important.
Thanks so much.

XDA user since 2007.
These last months I used to have a custom rom on my encrypted note 5 with no issue.
Until last week.
The phone refused to start after a shutdown ("Custom Binary block by FRP lock" message)
Just a black screen with this red message, really so at first it was kind of a malware before I knew about this 5.1 android feature that lock the phone in case of being stolen or modified.
What is really interesting is that Google guys implemented this "feature" obviously without taking in account encrypted users. So the message asking for the google account never appeared.
Ok. I make backups, it is not a big deal and I will flash a new rom with ODIN.
But then I realize it is impossible. This feature is specially made for preventing fresh factory reset.
The new roms + kernels I tried to flash (from 5.1 to 6.0) always display this message :
( device does not have DRK (device root key ), contact to SW PL
please flash ENG binary then install DRK
So I am basically screwed, and my phone is absolutely useless like it was stolen. Expect I paid $700 for it.
Really pissed of against Google and Samsung !!
The option to avoid this mess was : OEM unlock, I strongly suggest you to activate it before trying custom roms.
Hello fellas,
I have a SM-G930F running Super Stock Rom 2.8, rooted with Magisk 12. This morning I was a little high and worried about getting my device stolen (my S6 was stolen at gun point three months ago), so I disabled OEM Unlock and USB debug in Developer mode, in a crazy attempt to increase the security and make things more difficult for the thief. WRONG! I have really screwed things up.
Now I get CUSTOM BINARY BLOCKED BY FRP LOCK and my device won't boot. The DOWNLOAD mode shows FRP LOCK is ON, this means I won't be able to flash anything with ODIN because it will fail at writing (that is what the FRP Lock is for). I am at work and my computer has the USB ports disabled, so there's nothing I can do until I get home.
This guy did the same stupid thing, except that he wasn't high
https://forum.xda-developers.com/s7-edge/help/s7-edge-custom-binary-block-frp-lock-t3347688
I know that attempting a flash with ODIN can also cause this problem:
https://forum.xda-developers.com/showpost.php?p=71692103&postcount=25
As soon as I get home, I will attempt the Smart Switch Emergency Recovery Function and I hope everything will be OK. Since it was my google account logged in, I won't have any problems with FRP (theoretically, it will ask me to login with the last account used on the previous configuration).
[UPDATE] There is this ADB thing I am completely unfamiliar with, not to mention I have disabled USB debug on the device prior to this. This file will disable FRP Lock but I don't know the procedure.

Any help will be much appreciated. This is my only phone and now I can't use it.

Thanks for replying. Flashing stock firmware with FRP Lock will cause a write failure, are you sure about this? I will try it as soon as I arrive home. I didn't get that part where it will get stuck on google lock account, the device is mine and the latest google account used before was my personal google account. Could you please provide more details to complete the process?
I am also considering Smart Switch Emergency Factory Restore, that is my last shot before taking it to repair shop.
Dear sir kindly be sure the software is latest/i mean firmware
Hi,
had my phone locked too. Smart switch worked, aftter flashing twrp same problem. Got a factory rom from sammonbile and flashed cp, bl and ap with odin which brought it back.

I managed to solve it using Smart Switch, the firmware update did the trick. After restoring the system asked for last used credentials on previous configuration, like it was supposed to. Since it was my personal google account, there wasn't any problem with FRP Lock. Now I have installed TWRP and Super Stock Rom 2.8 again.
Leason learned, I will NEVER deactivate OEM Unlock again with a Custom ROM.
Thanks to everyone, this thread can be closed now.

hiiii can you help how to get out, i also have a private google account logged in plzzz help, i have also disabled oem mistakely
Thank You
Had no idea the dev options needed to be left ON regardless after rooting, or it rejects the custom binary? Would have thought the FRP lock would have been bypassed with the rooting. Can't enter twrp recovery neither.
And to be 100% clear, phone is rooted. Dev option was unticked w/o realizing it'd retroactively lock the phone as it detects the non-oem firmware and refuses to boot, refuses recovery, refuses flashing.
Can I somehow flash a stock firmare via Odin and NOT get the wrath of FRP? I found the stock firmware for the phone from Samsung's site. For some reason, the firmware.zip is like 1.4gb? Do I need to strip out a file for the recovery image assuming it'll accept it? Or just select the entire thing in Odin?
OK, flashed the 2.5gb (unzipped it had THAT much bloat) factory Samsung firmware, which took about 2.5 minutes vs. like 4 sec for the root .img :silly: and phone boots back up w/o issue, all personal stuff is intact, and unsurprisingly it adds all the bloatware back that I just deleted earlier.
So, if you accidentally turn off the dev options or I'm assuming the OEM unlocker specifically on your J7, and the phone refuses to boot as it's retroactively detecting "custom binary", OR if you happen to accidentally truly delete an important app and/or it can't be brought back with 3rd party apps, going to Samsung's firmware section, finding your EXACT phone/model/software numbers including the most recent OS and security upgrade to it i.e. 7.1.1 in my case, flashing it with Odin (site said to use most recent, so used v3.13.1) will restore the phone, unrooted of course. But it's better than a paperweight.
Greetings, ever since i tried rooting my phone, i knew something went wrong (i used cf autoroot).
So the first thing i noticed, i was asked to reset the phone or something similar to that, meaning i would lose all my data.
I tried to find a workaround as this had never happened to me before while rooting a phone, and someone had said that i was supposed to download twrp
and change some partition and then change it back. I dont remember what else he mentioned and what exactly i tried doing, i realised it was formatted either way and i had to start fresh. As i setup my phone i went and switched the oem unlock back to "off", as i did not wanna attempt to root again, but i hadn't realised that my phone was infact rooted sucessfully, leading me to my first error after restarting. "Custom binary blocked by frp lock", with absolutely no access to recovery mode at all anymore. Again, trying to find a workaround, i download some stockfirmware that i atleast had hoped was the right one for my phone, after a couple failed attempts of flashing with odin, ( i had gotten various different error messeges on download mode screen such as (REV Check fail device 7 binary 0 and others witch i cannot remember), now im getting a new error screen, stating that an error has occured while updating the device software. I cant flash twrp recovery as the frp lock is on, and the only thing i can guess is that im flashing the wrong firmware, but i cant find a matching code at all.
Its the following: sm-g930fzkadbt
IMEI: 35214310282955
on the back of the phone it says uk yateley, although the phone was purchased in germany.
Im not sure what to do anymore, any advice would be greatly appreciated.
PS: I have managed to get back to the old error screen with the custom binary info, this time with bootloop, by checking the deviceinfo box on odin
Yep you've now learned the hard way not to mess about and read the proper guides.
Anyway "dbt" is just unbranded german firmware. Download UK "BTU" and flash with Odin, it's UK unbranded.
FRP lock means you'll need to unlock the phone with the google account and password that was on it before you started messing about with it.
If you don't know the google email and password you need to read up on how to bypass FRP lock and it's a nightmare.

Thanks for your reply, just a question, will any btu update work? Should i download latest android version btu firmware?
(Also yes, it was stupid of me to try and do it quick but i had rooted 3 different samsung galaxy phones in the past without issues, either i did something wrong or it took something way too specific to do the job, perhaps the phone's unrootable, but thank you either way) :fingers-crossed:

You'll likely only find the last version of BTU think it was August 2019. It isn't updated officially anymore but it'll be fine to use.

OK so i thought it worked but i can only enter recovery mode now and download mode, but cant actually boot the system, it just boots up the battery screen whenever i plug the charger, and never shows the actual battery info, just the thunder icon. Formatting from recovery mode doesn't help either (Note whenever i launch recovery mode it says installing update, then says no command and brings me to the recovery menu) Any ideas?
PS: It fixed itself. Sorry for the pointless edit.
good guys, I need a lot of help, two days ago, I had the bootloader unlocked, since it came with a firmware from last year and the operator, I installed the latest firmware to get the operator logo and installed twrp , when i went to install the sabor rom, my phone crashed, and i came across samsung's message that i can't install unofficial binaries, i was forced to reinstall the stock and get stuck in it, without telling twrp. i wanted to know, how I exceed or circumvent the kg state: prenormal. this kg state stay in download mode and never comes out again. How do I overcome this and reinstall twrp? I really need your help!
if someone has a program or charges for the service, I pay, no problem, as long as it's cheap!
