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.

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

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:
Hi
Please can someone help. I have just got a Samsung galaxy s7 and was trying to get back some pictures I accidentally deleted using a program called Dr Fone. I followed the instructions and didn't realise I was possibly rooting my phone
The phone is on Status custom and I just want to restore it to how it was originally. I have reset to factory settings but this hasn't corrected it. I am constantly getting a security notice about unauthorised actions
I am not very technical so if anyone could help please give the exact links for where I can download a program to repair this - I have read about a program called Odin but not sure exactly where or how to find this. Does this need to be installed on a computer or phone?
Some more information on the phone is that it's a UK phone. Firmware CSC code is BTU if that helps. It's an S7 SM-G930F
As I said I am not very technical so please can anyone help and if possible provide a step by step guide for what to do that would be amazing
Thank you, David
Odin is a desktop application, it is uses to flash firmware onto your phone. By flashing stock firmware you'd get your device back to stock (excluding KNOX and FRP)
Here's a detailed guide on what Odin is and how to use it https://updato.com/how-to/how-to-install-an-official-samsung-stock-firmware-using-odin
You can use that site to get the firmware for your device by region and carrier.
Ok great thanks
Please can you tell.me what excluding KNOX and FRP means?
I will give this a go. Have started the download for step 3. This download seems to be taking a couple of hours. Do you know roughly how long it takes to put everything on the phone once the download if complete?
I may have to leave the actual installation until tomorrow if it takes a long time.
Thanks again for all you help
KNOX is a way for Samsung to check if you have altered the firmware. Flashing custom firmware and/or rooting trips the KNOX counter, and will void warranty and disable some Samsung apps.
FRP is factory reset protection, if prevents someone from being able to steal your phone and get access by factory resetting. Even after a factory reset, FRP is intact and will require the original google account to do the device setup. So make sure you know your credentials, or delink your account before flashing.
Both are part of the firmware that can't be modified or reverted.
Updato can be quite slow to download, sammobile.com is another site but also slow in my experience. The flashing process takes about 15 minutes on your PC, but the phone can sit on the Samsung splash screen for 15 or so minutes as well.

Great thanks for all your help so far. I have completed the ODIN update and got the green pass. The phone is trying to boot up and is saying it is encrypted for security and asking for a password. When I put what I thought was the password in it doesnt seem to accept it, is there any way around this?
I read on another message to try the password default_password but this hasnt worked
I have realised that when I flashed the AP download to the phone that there were 4 other files that were downloaded after I unzipped it. Do I put these into ODIN too?
Thanks again

There are 5 files. You have to flash 4 BL, AP, CP, CSC (not home-csc !) Keep in mind if you previously had firmware from January 2018 and up you can only flash equal or newer firmware.

Short question: how can I downgrade or FRP unlock a S8+ G955F that is FRP locked and on very recent firmware?
Here are the details:
I am trying to assist a family member with a Galaxy S8+ (SM-G955F) that they have just purchased online. When purchasing it they were not told that FRP lock is on (FRP LOCK: ON) and OEM lock is on (OEM LOCK: ON). It was running Bootloader v2 on very recent stock firmware. It has been successfully flashed with BL_G955FXXU2CRED and AP_G955FXXU2CRED...
It was on G955FXXU2CRED firmware. I was able to successfully able to flash the Combination ROM COMBINATION_FA70_G955FXXU2ARE1 (full name COMBINATION_FA70_G955FXXU2ARE1_CL12792727_QB18097821_REV00_user_mid_noship.tar)
With combination rom, it seemed that I could enable USB Debugging, and also follow the steps for *#0808# IME to enable the appropriate mode for adb codes to be entered. I was able to find the device with 'adb devices', and I thought that the FRP unlock codes on the command line worked. But after re-flashing to the current Stock Firmware again, FRP lock was still there.
It seems I need to downgrade to Nougat 7.0, but I am on Bootloader V2. Odin identifies it by a FAIL with binary not matched (2 vs 1). So it seems that if I could get a method to keep Bootloader V2 and install Stock Firmware for Android 7.0 Nougat, I would be halfway there to fixing the FRP problem. However, I can't find any firmware or ROMs for G955F that includes Bootloader V2. This is identified by a U2 in the firmware name, like: G955FXXU2CRED . Is there a way to keep the BL Bootloader V2 but install AP ROM from Nougat?
I have spent many hours on this so far, and I just wanted to say thank you to all you guys who are helping on XDA, I really appreciate it. I have read about 7 day waiting periods for OEM UNLOCK but I don't see how it applies, as I can't do anything aside from use Combination ROM, use Odin, or go to the FRP locked FW which seems to be a dead end?
If there was a reliable method for rooting this G955F device with this G955FXXU2CRED firmware, I would be open to trying it.

Another note: AP SW Rev is identified as B:2 K:1 S:1
I don't think once a phone has the boot loader CRED, that the phone can be downgraded. Hope I am wrong.

I think you are right. The combination ROM seems to built on selinux version 7.
I think I need to root with twrp. But first I need to enable OEM unlock. I'm not sure if that will be possible with combination ROM or if I should flash latest stock and then wait 7 days??

I think I read someone on CarHDRom who flashed the rom via TWRP, and then when the phone booted into system for the first time at setting up, they changed the date to 8 days earlier, and when the phone setup was completed and booted into system, the OEM unlock was available.
Re: CRED I believe once it has been installed on a phone, you can not go back to a previous version (pre CRED).

Download latest odin and try again. I too got stuck in similar situation. Realised the issue is due to Odin. If you are using latest and encountered this error, try one version earlier.
I too can confirm that the combination-ROM works like a charm with odin. FRP kinda unlocked itself
I've searched in vain on how to manually update to latest security patch, now that Sammy informs me that my device has been modified in an unauthorized way and will not allow OTA updates.
In sammobile I can see that my phone has a new security update. My question is if I have to install the complete firmware or security updates are available from some other source?
With respect to the latter, Sammy doesn't seem to make security updates available on its page and I would have preferred just patching a smaller file and not the whole firmware.
Any guidance appreciated.
Cheers!
if u use the home csc file when flashing new firmware with odin ur device will not been wiped, just updated without losing data.

Many thanks Roberto, for your answer. Unfortunately, I have a few more questions which I hope you can help me with. At the SamMobile it says Download Odin v3.13.3 and running it displays the following warning: see image here.
It says I have to: ...delete my Google account (Sammy account) before downloading the binary. I suppose that by "downloading" they mean moving firmware to the phone, but it doesn't seem very logic...?
The unlocking referred to I suppose is the OEM unlock, and no problem there.
I haven't found any explanation why this new measure of having to delete the Google account is necessary and wonder if you could help clarify it?

1. If flashing stock firmware you don't need OEM unlocked.
2. OEM unlocked is used for flashing non signed Samsung files/firmware. IE: twrp,root etc.
3. Using the home_csc ( not CSC ) as stated in the previous post should keep your data. It is recommended to flash the 4 files when upgrading. But always do a backup first.
4. If you have twrp or root you will need to redo again.
5. Usually deleting any accounts from your phone turns off FRP protection.

Thanks spawnlives for your response.
As mentioned in the subject I had TWRP and Magisk, and, first time around I was aware of loosing apps, their configuration and internal data. I would think the same would happen any subsequent times - hence my question how to install only the security patches.
I suppose it's not possible... In that case, with security patches for my S7
sometimes every month, it's not worth going through the hazzle of adding TWRP and Magisk.
Shame on Sammy penalizing rooted customers when it won't update the Android version of more than 2-year old phones.
Another, shame on Sammy has to do with how security patches are more frequent for "important" countries (i.e. where Samsung sells most). In the previous link above, just select another country, say Costa Rica, which only has received one security update for this year - as opposed to three for Germany. Why?
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.
