Help with FRP Lock

Hello everybody,
I usually find my answers in the specific phone related forums. But this time I'm stuck.
A friend of mine bought a Samsung Galaxy J7 (SM-J700F to be specific) in India. After using his phone there he came back home to Israel.
His phone didn't worked here for some reason and he went to a phone lab which flashed his ROM to stock Israel ROM.
They called him in the middle of the process and asked him what was his Google account thet he signed to while the first setup. Unfortunately, he cant remember his email address.
I took the phone to try bypassing the frp lock.
After a small search I realized I need an otg cable, which I bought.
I received the cable (1.5 mounths wait) and tried the otg cable method with no success.
After some experiments I successfully managed to open the settings menu. Pressed factory data reset and after a restart it stopped on recovery menu with the yellow message "dm-verity verification failed".
Well, this is annoying. I realized I need to flash the stock ROM again(Dated 01/16). So I did And the message dissapperd.
Back to the FRP lock issue. I did the process again and it didn't stopped in the recovery mode this time and I could see the Android logo with a little erasing.. Under it. Finally I thought.
I was wrong.
The FRP lock is still there! Dammit.
It is time to pull the big guns.
I thought I will flash the OLDER version of the stock ROM. Dated 09/2015 I Understand google updated the FRP lock protection on January 2016. Is the downgrade OK? I don't know if a downgrade is possible on Samsung phone.
And if you have an idea how to bypass this. Please share it.
Thank you so much!

How do I downgrade to an earlier version of 6.0.1?

Long story short. I'm helping out my colleague who got her phone locked. We ended up factory resetting it, but she's not the most technical, so it seems that every time she's gotten a new phone over the years, she's just created a new gmail-account and forgotten about it.
Then FRP kicked in. Shouldn't be a problem if she just knew her account.. We've found out that she's got at least three accounts, but none of them works. I figure she's got another one, but not one that she could remember. So I have to bypass FRP somehow, otherwise this phone will be an expensive useless brick. :/
It seems it's on build MMB29K.G930FXXU1BPJE.
It's recently updated, so any bypass I've found seems to have been patched. It's usually a good thing, but in this case (she can blame herself, though..) it's a bit sad.
I've tried to downgrade using Odin, but for some reason it fails. I've haven't been able to enable OEM-unlock or enable Developer options.
Any help is appreciated!

She should have some record of which account she used, creating a Google account should ask for a backup email address for recovery, so one of her accounts should have the details of the one she's forgotten
Otherwise unfortunately this could just as easily be "I stole a phone and want to know how to bypass FRP"

Octoplus box and your problem is solved.

I know. At first she couldn't remember the gmail, and after we checked against her phone no. we found two accounts. Checking against her work e-mail, I found another. Unfortunately it was none of them.

All I can suggest is look for tutorials on YT for bypassing FRP for whichever security update that phone was on / downgrade with ODIN to one that has a tutorial (Try leaving out the BL part of the flash if it's failing, and use CSC, not HOME_CSC)
You should definitely be able to downgrade a G930F, I just did with mine from 7.0 Nougat back to 6.0.1 using ODIN 3.12.3
You don't need OEM Unlock or Dev Options / USB debugging for flashing stock with ODIN

Thanks, I'll give it another try later tonight.

Following this video (https://www.youtube.com/watch?v=KRUp09bXnDA&feature=youtu.be) I didn't have to downgrade anything other than the account manager on 6.0.1 through an .apk. That way I could bypass FRP on the October security patch. She was so happy, and I told her to keep it to this one @gmail-account.
So, problem solved! Thanks for the replies!

Nice one :good:

Galaxy S7 FRP Unlock on Nougat

Hi guys, i have a galaxy s7 of a customer that doesn't absolutely remember email and password for his google account connected to the phone(and so it's OEM Locked).
i tried to follow many guides on the forum but this happened:
i can't root the phone (because the FRP is locking the Flash),
nor install 6.0.1 (because of the error "sw rev check fail device 2 binary 1")
i can't use bluetooth method to skip setup guide (it was fixed in 6.0.1)
i can't use RealTerm because it can't make me save the number to proceed the guide(also fixed in 6.0.1)
what can i do? how do i bypass the FRP? or how do I downgrade to 6.0.1?

Downgrading can be a problem caused by the bootloader, make sure you try to flash a stock ROM with the same version bootloader as shown with this number
G930FXXU2ERD5
The customer would have had to enter a secondary / recovery email while making that Google account, tell them to check their other email addresses for confirmation emails around the time they set up the phone, then they can find the email address of the google account and reset the password to that email address

You have to downgrade to 6.0 and then there are plenty of ways to unlock.
Download 6.0 and latest firmware.
In Odin
1st and 3rd field from old firmware
2nd and 4th field from new firmware
If You need guide how to unlock from 6.0 let me know

1st and 3rd field in ODIN is Bootloader & Modem
If you flash new firmware to 2nd and 4th you'll end up with new firmware flashed with old bootloader and it won't boot most likely / brick

AP is the system / OS, you're telling OP to flash a new version of Android (AP) with an old bootloader, in order to downgrade to 6.0.1, your method would not downgrade anything other than bootloader & modem and old bootloader with new OS will almost certainly brick
To downgrade you need to flash old bootloader (BL) & old Android 6.0.1 (AP), and probably old modem (CP), CSC is the only thing left
And as already stated, downgrading the BL is the problem that prevents most people from downgrading in the first place

I've been absolutely stuck for days trying to sort out the bloody FRP lock on an S7 (SM-G930F) that had been gifted to my wife by my father-in-law where he hadn't removed the accounts before passing it over.
My wife then did an update that the phone requested when it started up and that went wrong at which point I get involved and factory reset it...oh BIG mistake... and that's where my problems started made worse by the fact my father-in-law couldn't remember which account he had setup on the phone....or even the password to possible accounts!! I consider myself to be well versed in all things tech but I had absolutely no idea FRP existed and was absolutely baffled when i saw the message on the screen after flashing the stock firmware (G930FXXU2DRB6) that was on there according to the recovery mode. I've been trying so many different things over the past week all current methods failed...then I came across this one...which had seemed to be blocked by admins but I was able to click on the link in the 2nd post and grab the password from the readme in the first, which i must admit made it a bit dubious and not sure why @S6unbricker felt the need to do that but there's no issues it doesn't go to a stupid survey site or anything it just goes to a text file on mega which has one line and that's the password!
I followed the method to the letter and, to my surprise and joy, it's actually worked a treat...the S7 is no longer a paper weight!!!
Massive thanks to @S6unbricker :good: ...any chance of re-posting but without the password on the file or putting the password in the post?

Frp doesn't block eng bootloader...after u flash eng boot u can simply use Abd command to remove. Or the longer method flash factory binaries. Enable oem unlock (most important part). Then flash stock rom make sure to remove userdata.img ....on a side note wondering if adding the Samsung retail app and activating it, then using the login data to remove the app via factory data reset might work.

From my experience the combination roms (which I presume you are referring to when you say eng bootloader) didn't solve my issue. Yes I could get them on the phone and boot into them, change the settings or use adb but obviously I don't want the factory binary to stay on there so as soon as I flashed it back to the current firmware, back to square one!
Most poeple advised to use HOME CSC instead of CSC when flashing from combination rom back to stock but I couldn't get odin to flash with HOME CSC.

No I'm referring to the boot.img file. Combination ROMs don't enable su access via she'll.

Samsung s7
Ok I know this is an old Post but I'm brand new to Odin and all the unlock lingo.. can anyone explain to me how to downgrade to bypass the frp on my Galaxy I just bought , I'm very tech savvy just need a walkthrough any help would be greatly appreciated

G930F Stuck on Factory Binary

So I had this S7 my father brought me to fix and appearently it has frp lock.
I followed some instructions and ended up installing this COMBINATION [COMBINATION_FA60_G930FXXU5ASD2]) from a website i cant link because i'm new here (hardreset dot info)
What happened is that i can boot into this factory binary > settings > enable usb debugging, but when i try to flash a new firmware i get only fails from odin. I guess it's because of FRP lock.
I've tried to flash other combinations, but the only thing that works is that particular version that i cant find anywhere else on internet ( COMBINATION_FA60_G930FXXU5ASD2 ).
Can anyone give me a hand? I'll ask to every question you need. Thanks a lot. :fingers-crossed:

Once you flash a firmware that works delete the ****ing Google account off the phone. Can't believe how many people mess about with phone without learning the basics. FRP lock is a mother ****er to solve but there's loads of guides.

Trust me there's no account to delete. I've followed lots of guides, all of them dont work because i cant flash anything into the phone for some reason.

samsung galaxy s7 custom binary blocked by frp lock

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.
