S7 FRP locked with Oreo 8.0 - Samsung Galaxy S7 Questions and Answers

Hi all.
Got given the mother in-laws old samsung S7 for my eldest daughter. So not having had a stock samsung phone myself for quite sometime, booted into recovery to factory reset the phone and have now found myself with a FRP lock.
I've made an attempt at following some of the FRP quides but it does seem Oreo is far more locked down then previous versions.
Does anyone have any details or Is there any quide that works with Oreo? or is it just easier to just contact the in-laws and ask for their google credentials?
Cheers.

Cheers for the reply, My phone doesn't have the emergency call option, is there another way?
Phone is currently running G930FXXU8ETI2 firmware.
I understand i can't downgrade but would flashing the latest firmware, G930FXXU8EVG3, help?

Are you sure you took out the SIM?
If so, show the screen from the stage as in the 24th minute of the movie.

Turn the device on im presented with the start page, going through each step to connect to wifi up to the login in page telling me the device is locked. Pressing the back button to return to the start page and there is no emergency dialer option at the bottom.
If i press 3 times at the bottom of the screen i can enter the qr code setup, swiping up from the bottom of the screen in the QR code reader promts me to install samsung pay. Pressing the back button returns me to the start page, still no emergency dialer.

In revovery mode, do a wipe data/factory reset to get rid of the google account, and then repeat the FRP removal procedure.

Samsung galaxy s7 device status custom / security notice unauthorised actions

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.

G930F locked on Combination firmware

Hi guys
I need a helping hand.
I have a s7 (G930F fxxu2drb6) with frp lock.
It did not work either realterm, bluetooth, or downgrade (SW REV CHECK FAIL DEVICE 2, BINARY 1 SAMSUNG).
On gsm-hosting they suggested to me to flash the combination file "COMBINATION_FA60_G930FXXU2ARA2_CL7964511_QB165812 9 6_REV00_user_mid_noship.tar.md5".
After the flash I can not yet downgrade (W REV CHECK FAIL DEVICE 2, BINARY 1 SAMSUNG), not even flash again "fxxu2drb6" (FAIL RQT_close).
Can someone help me get out of this situation?
Thank you in advance

Hello. I have a similar problem. I have the latest firmware on it: G930FXXS2DRDI There are no ways to lift the Google lock. I have tried everything possible: Bluetooth does not work, Talkback, Realterm, etc. Please for help

Hello my friend, i have this problem too. Have you a fix? this security patch for FRP is incredible....
You CAN bypass FRP on later Samsung models using Combination FW. I have succsesfully done this with S8+/G955F, it should work with any device that has compatible Stock/Combinaton FW.. Here are the steps. Download a compatible STOCK ROM, and some similar COMBINATION FW (by similar i mean both FW to be with the same binary and same android version, duh..) Here are some firmware download links, but you can use whatever you want, according to your device.. G930F STOCK ROM/G930F Combination FW
First, using Odin flash the COMBINATION FW to your phone. After flashing is complete and the phone reboots, allow a few minutes for the phone to boot. If it doesn't boot/gets stuck at bootlogo, reboot/boot to recovery and wipe data/cache, and reboot again. MOST IMPORTANT THING! After the phone boots, go to Settings, enable Developer Options if not enabled, enable USB Debugging, and turn the device OFF using Power button. After the device shuts down, enter Download mode, open Odin, place all 4 files in their respective fields (BL,AP,CP,CSC), and here is the SECOND MOST IMPORTANT THING! In the CSC field place the CSC file that starts with HOME/HOME_CSC (There will/should be 2 different CSC files in the FW archive, one starting with CSC, and the other with HOME_CSC). After flashing is complete, allow the phone to boot normally (don't do anything, don't enter recovery/wipe data). If you followed my instructions correctly, after the phone boots, you should be able to finish the initial setup/skip all steps, without requiring any account. Then go to Settings, enable Developer Options, turn OEM Unlock ON, and finally factory reset the device to complete the process and start fresh.
Don't forget to hit THANKS button if this method worked fo you!
ATRAC3, do you have the combination files and firmware for the SAMSUNG S7 SM-G930FD please and thank you for your wonderful tutorial here.
my odin(tried on v3.12.5/v3.12.7/v3.13.1 ) keep failing while flashing HOME_CSC but will success with CSC, and still required to login google account, what is the issue here ? (are we supposed to insert the pit file by ATRAC3 ? )

Hi mate ive used the G930FXXU2DRBE XSA Firmware and also G930FXXU2DRB6 firmware with the G930FXXU2ARA2 combination rom however it will not boot past the samsung logo the nad passes and is provisioned in top left corner and when plugged into the computer comes online with ADB bypass flasher but it just sits there even if i do a cache wipe and factory reset it comes up with a tango console error or something like that when reset then reboots back to samsung logo and when re installing firmware HOME-CSC will fail every time the only thing ive been able to put it down to is that (1) the firmware is FA_70 which is nougat OS and the combination rom is FA_60 MM or (2) my knox warranty bit is tripped and will not allow a samsung factory binary to be run on it, may i ask what would be the difference with the firmware you have listed to the firmware im already using with the combination rom ? Need to sort my imei number out with the factory nad asap dont have access to my TWRP backup for another week and a half, if it helps my device is not FRP locked and is oem unlocked.
Thanks
Matthew
P.S to all those whom have a bit 2 bootloader on S7 all the loopholes have been patched the only way is to use the combination files ive been through absolutely everything and tried everything this new bootloader update is impenetrable i can google unlock samsung S8 and S9 no dramas and with S9 the OEM lock option dissapears for a week if tampered with but still 15 minutes and its done this **** but got me goin loco holmes !!!!! Maybe they figured this out also as there is only bit 1 bootloaders for both the S8 and the S9 however with S8 i found a stock firmware that allows another way to unlock the device without the need to flash any combination rom.
So in short no hope now to unbrick our Samsung S7 SM-G930F/FD or what.....?

If it gets stuck on the console error and wont reboot to download mode then hold the power button volume down button and power button for 40 seconds and it will re boot to download mode for stock firmware re installation in short basically no theres way to remove the FRP unless you can get the combination rom to boot which from what ive seen some will boot the binary but then it also depends if HOME_CSC will flash to keep usb debugging enabled to use adb bypass program im now using the new G930FXXU2ERE2 8.0 OREO so I've given up on the binary 2 nougat FRP unlocking for now might be best to wait a while for someone to receive a factory binary on the nougat or oreo when sent off and returned so it can be dumped and built into a flashable rom until then not much can be done and i may have to wait another week and a half for my EFS backup :'(
We will be waiting from u for the new combination file when out bro, our hope are hinged on u!
No one is coming up with any method about the bootloader binary 2 for the Samsung S7 G930FD...?

S8+ G955FXXU2CRED with Bootloader V2 - options for flashing, downgrade, FRP Unlock?

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??
same problem here... If an solution available pls write here

Flashing stock rom and waiting 7 days would be the safe option.
I am not exactly sure what you are trying to achieve.

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).

I wonder if I can do this date trick with combination FW to enable OEM unlock.

It seems there are a few solutions to frp if you can selectively restore flash files. It looks like Samsung tool Pro can do this, but is there any free adb method?

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.

Excellent.
I still can't get this to work. Have you purchased Samsung tool Pro to do the flashing of individual boot files? What version?
Hi there. I already bypassed the frp.. If you need. Hp with android 8.0 even with the binary 2. I have some comb files and working stock roms through odin. Feel free to pm me via my email [email protected]. Thanks!
how

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

Samsung Galaxy S7 - SM-G930F FRP Lock Android 8 Problem

Hello, I have since 1 week the problem to unlock the Galaxy S7 SM-G930F. Since my little brother does not have the e-mail and password anymore, and so we can not get in the phone, after a factory reset, Google wants to verify the I but what about the data we have is no longer possible. That's why I've tried everything the FRP lock somehow but everything fails ... I've already tried that with the binary 2, but does not work, the download mode tells me the following error:
sw rev. check fail (bootloader) device: 5 binary: 2
And now I do not know what else to do, I've already tried to downgrade to Android 7 or Android 6, but it does not work, Odin always says FAIL.
I hope you can help me somehow, otherwise I just do not know how to continue.
Download Mode Details:

PRODUCT NAME: SM-G930F

You cannot downgrade the boot loader, your phone is version 5 (Device 5) and the firmware you are flashing is version 2 (binary 2) . 5 to 2 is not possible.
There are many guides how to bypass FRP lock on Oreo, you will have to find one that works. Try YouTube.

I did not understand your answer at all, you may like to see my YouTube progress, all I found are fakes. There, people show that you should put the SIM card in and out again and that should work, but it does not.
i have thesame problem

you simply have an incorrect combination file, more specifically the version number is incorrect if you boot the phone into recovery mode first it will show you a firmware version looking something like G930FXXU5ASD2 the parts you need to pay atterntion too are the u5 and the 2 at the end the u5 is bootloader version you CANNOT down grade find a combo rom with same bootloader version and flash that then open the app "factory ime" and punch in *#0808# select ap and dm+modem+adb , reboot phone run your choice of frp program i usually get mine from techelegible website after u run frp program reinstall 4 file stock firmware do flashing using either prince comsey odin or odin 3b i get firmware from androidfilehost usually good luck happy hacking
