Remove FRP, anyone got any recent guides? - Samsung Galaxy S7 Questions and Answers

Hey peeps,
I have a SM-G930F based in Aus and I can't seem to get around the FRP lock. My gf forgot the login details.
I cant seem to get around the FRP lock at all, tried flashing TWRP, tried flashing stock firmware from sammobile, nothing seems to get around it.
Anyone got any ideas?

Flashing won't get rid of it, its entire purpose is to persist through attempts of factory reset.
You'll have to use an FRP bypass exploit, the older version of Android the more exploits exist, so your best bet is to try flash MM or N via Odin and try one of their working exploits. But if the device is the latest version of Nougat or Oreo, it will likely block your downgrade attempt.

Does this also apply when rooting + flashing a custom rom?

To my knowledge, yes. FRP is part of firmware and storage that users can't access or reach, which is why it persists through everything.

Root and security question

If you lose your phone or it gets stolen;
With rooted phone, a person can install a new rom and use it right?
W/out root, your phone can be bricked permanently if someone tries to factory reset? Via google or samsung account. Also, you can't use odin to install any ROMs?
Or has the security on the newest android phones like s7 now have better security even when a phone is rooted?
I'm on a verge of trying to decide if I should root my S7 or not.

1. He can either way wipe data. Root or no root. The question is can he skip the factory reset protection. There are ways to skip it. But this again has nothing to do with root on the phone.
2. There is currently no permanent brick. There are blog posts which suggests something like this would come in new android versions.

Galaxy S6 Edge SoftBrick (DRK)

Hi,
I've one (big) problem that I can't fix.
I've been using Android 5.0.1 for more than 1 year as I didn't want to upgrade (it worked pretty well) and because I had the S6 rooted with PingPong root.
However, one month ago it started to run slowly, crashing apps, ... so I decided that, as I wanted to wipe the device, why not upgrade to MM (6.0.1)??, so I did.
I did a backup of all my data and EFS folder and downloaded a 6.0.1 ROM to flash it with ODIN. Everything went OK and finished flashing the rom, but when the S6 restarted it showed this in the recovery:
'dm-verity verificztion failed...
Need to check DRK first...'
And I cant boot.
I've tried some tips that are here and in other websites:
- I've flashed stock rom again
- I've flashed a stock rom without cache.img file.
- I Can't flash some files as I've R/L ON. (I've been trying to disable it for many months but I couldn't).
But the S6 doesn't boot...
Thank you!
What worked for me.
So this is my current issue, but i was able to resolve the issue you are having. so what i did was get the 5.1X OK7 (My phone is Verizon) firmware and flashed through ODIN 3.12.5, this flashed stock 5.1.1 in my phone and it worked good. however i have issue with my phone random restarts and power button not working in recovery or in rom. however i can go in and out of downloading mode or maintenance mode.

Thanks for your reply!
I tried to downgrade to 5.1.1 or 5.0.1 but I get an error.
(SW REV CHECK FAIL DEVICE 2 BINARY 1)
That happens when you don't have the right firmware you have.
You CANNOT downgrade to 5.1 or 5.0 since you are on 6.0. The bootloaders refuses to be overwritten.

I'm trying to flash another 6.0.1 ROM (a bit older), but I get 'CHECK FAIL. DEVICE: 4, BINARY:3'
I've read that DRK problems are related with EFS files, so... Can I restore EFS folder (I've a backup from Android 5.0.1) to solve?? I don't know how to restore it without booting into the sistem (and without custom recovery)
I am afraid that downgrade to 5.0.1 is not possible, at least I dont know anyone who succedeed in doing that.
If you were on systemless root, probably your Knox is still 0, check it in DL mode, if it is and you have the phone less that 3 yrs (1 yr warranty+2yrs factory warranty) best solution would be to ask in Samsung repair center if the factory warranty would be accepted (ofcourse dont mention flashing, just say you tried official update, and play dumb).
If not you can try custom kernel wich will bypass DRK, and prolly make the phone bootable, but there is no guarantee everything will work well (maybe it will, but mostly it doesnt, forget using Samsung pay, and KNOX tripped)
As for EFS, maybe I am wrong, but I think EFS contains IMEI and sn info, and DRK is something else.

Thank you for your reply!!
I had the device rooted, but with PingPong root, so Knox is still 0. However it shows that the system is "custom".
I'll try the warranty, they may not notice the "custom", just the knox.
I'm with the same problem when trying to flash stock BTU QA7..and only if i flashing cf_root my phone is booting.
Any idea? I don't care about the Knox..

If you are talking about DRK, the only way to fix it that I know of, other than hw replacement, is via 3rd party professional repair tool. (Octopus/Octoplus box)
If DRK is ok, phone boots normaly, if it is messed up, the only way of booting is with custom kernel which bypass DRK check.
You can check it in recovery, if messed up it will say DM verity failed on bottom of the screen.
Ok, i send my phone to fix, i will tell you what happened.

Thanks for your reply!!.
I took my S6 (925F) to a Samsung service center as you said. However, they told me that my S/N was incorrect (I bought a second-hand S6 edge, I think someone changed it) so they couldn't fix it.
Now I'm trying to use SmartSwitch to do a factory reset but it asks me for the S/N and I don't have the original one, just a S/N from a non edge S6 (920F). How can I do the factory reset without my S/N??? Can I use the serial number from another 925F??
Now I'm trying to find an engineering bootloader, to bypass the R/L and flash CF-AutoRoot, custom recovery.... but I only find it for 5.0.1 or... for galaxy S6 G925T, not F.
Finally, I managed to fix my S6 by myself!! (not really, but at least it boots...)
This is what I did:
- I found a factory binary for my S6 so I flashed it via ODIN
- I flashed a 6.0.1 ROM without hidden and without cache
Then it boots without any problems. However, now I can't get into recovery
I hope this will help someone

S7 edge current situation.

Hi there I've been away from rooting for a bit and i have been trying to root a broken s7 edge more recently. Its got 6.0.1 stock on it. It all works except the volume up button. I seem to be able to access the phones files and sd card in windows. I can also flash 6.0.1 it seems by forcing it into download mode. But its still stuck on FRP and i can't find any way to unlock the bootloader to install custom software. I've been trying all the tutorials i can find but none work. Is this Samsung patching these security holes and so they no longer work? The password Is unknown for the Google account and it's not blacklisted or anything like that I've not used the SIM in any tutorial though. So is this doable or is it impossible at present? It all seems a lot more secure since my last root :s Thanks

Try this for bypassing Factory Reset Protection(FRP)
https://www.progeeksblog.com/bypass-factory-reset-protection-on-samsung-devices/
Or this
https://www.xda-developers.com/rootjunky/
As for rooting the device, there aren't many methods that work on lollipop and newer firmwares other than maybe trying Kingroot and Kingoroot or flashing TWRP(not an option for you since you have a locked bootloader) for your model number then flashing Super or Magisk.

master reset code

Hey i have a Canadian Samsung Galaxy S7 SM-G930W8 model and when i bought it second hand buddy did not remove his google& Samsung account which is preventing me from having my OWN phone and i want to factory reset it and cannot do it through the setting (powered on) and in recovery it says that it will require the Google account that is currently on the phone be signed into once the reset is complete stupid FRP protection. I found the Samsung master reset code online and im hoping that will work but wanted to ask the community before i tried just to be safe. Please any helped is greatly appreciated thanks.
ALSO its running the july 1 2018 security patch and android 8.0 ored
The only way to get past FRP is the google account or an FRP bypass exploit which are all patched in Oreo.
Take it back to the seller and get them to unlock it for you.
Its not lock i have full access i am trying to get rid of his Samsung & google account if i could root it i could get it but cant seem to find a rooting method for this phone ..... Im not locked out of it i have 100% access just need his account removed
G930W8 is Exynos, so you should just be able to flash TWRP and then flash a root zip. But if you factory reset its going to lock down. https://forum.xda-developers.com/galaxy-s7/development/recovery-official-twrp-herolte-t3333770
Downgrading to marshmallow and using a bypass method (even though it's not locked, bypass lets you change the google account) may be your best bet.
Ok so downgrade to 6.0? And then find a frp unlock for marshmallow and then i dont kno how to run the bypass never had a phone with this nonsense ..... As for the root method which root file would i have to get i could then have my brother write a snippet like the old "remove gapps\knox\samsung apps" i doubt the old one i have would even work lol
Lookup FRP bypasses on youtube, there's many methods and at least once will work - it's not a simple process however.
In that TWRP thread I linked is the Super SU flashable zip, or Magisk would be the best root methods.

Galaxy S6 Secure check fail : (recovery) help, installing TWRP

I have been trying for about a month to root and atleast boot this SM-G920V to a rom I dont even care if it's rooted but anytime i try to follow a youtube video exactly it still ends up failing i have used adb to boot to bootloader then turned off phone booted into download mode to bypass the secure download but it still says SECURE CHECK FAIL : (RECOVERY) I don't quite understand why Verizon just has to be so difficult but this may be a dumb question is there anyway to actually switch the model of this phone without just changing that file that displays it to thus switch it to a root compatible version or will changing that actually make the phone compatible I don't know if anyone has any tips as to booting this verizon galaxy s6 nougat 7 to a custom rom or even rooting though I was told that the verizon models are incompatible for unlocking bootloader but I know theres ways of booting to roms without unlocking bootloader though you need root is there anyone that doesnt need root or unlocking bootloader I have also tryed the old ping pong method and that still failed. please let me know if you have any knowledge of any of this thank you in advance
No way for custom rom.
Flash the latest official, install Package Disabler app and get rid of the bloatware.
Then enjoy the phone.
