Hey everyone,
I am new to the programming scene and this forum.
Anyways, I run a repair business in Ontario and have repairs come in daily. In particular today, I had a Samsung Galaxy S7 come in for repair and the issue the customer explained was they forgot their pin or pattern lock. I used to be able to use TWRP and go into the system and delete the gesture.keys without losing all data but I read up on the new technology now with Knox and bootloader and I was told flashing TWRP on the Galaxy s7 without bootloader unlocked will cause bootloop. All I need is to get into TWRP to delete those keys because customer CANNOT lose any DATA (very important). Is there anyway to get TWRP on the Canadian variant without wiping or causing a boot loop. I don’t need root. Just need access to the system files from recovery to delete that key file. Unless someone else can chime in and offer another solution, but please HELP!

If the bootloader on that device is locked, you won't ever be able to use TWRP at all, not ever, not by any means.
If you know exactly what firmware build number thay had installed before this happened, you can try flashing that exact version of stock firnware via Odin. As long as the firmware that you flash does not contain a different(upgraded/downgraded) bootloader, it "shouldn't" wipe their personal data but it does wipe the user settings(pin/pass in this case). When flashing via Odin, the user data does not get wiped unless the bootloader on the device is upgraded or downgraded during the flashing process. Their data should stay intact if you use the firmware version that is already on the device.
If the bootloader is locked, then regardless of what you do, flashing the firmware is the only way you're going to fix this, whether it wipes their data or not. Flashing the current firmware that is already on the device is really your only option.

I’ve managed to reset the password because cudtomerbhad her Samsung account linked to the phone. Logging into Samsung online gives you the option to remotely unlock the pattern. She now has all her data and password is gone. Thanks for the quick reply regardless

Ah yeah, I forgot about that option because I don't use the Samsung account feature on my phones. Plus, I was looking from a perspective of what could be flashed or not without causing data loss.

Quick story: bought used phone on craigslist with good esn, brought it home, (DID NOT do my research about samsung account lock beforehand)...did a factory reset, previous owner does not have samsung account information to give me., and won't take back the phone. I've been messing with it for 2 days and about ready to sell it on ebay or buy a used motherboard....
After the initial factory reset it booted to setup normally, after a few failed attempts at the samsung account lock username and password, it rebooted. Now the phone is stuck in a boot loop, it reboots after about 30 seconds, after just enough time to select a language in setup
I can get to download mode but it shows "reactivation lock: on" First tried clear cache partition, and a few times factory reset.
This was as a result of just a factory reset not flashing any firmware or anything.
This is phone model g920v (VZW) running 5.1.1 OG5
LMY47X.G20VVRU3OG5
I can boot to download mode and android system recovery just fine, and the phone will not reboot, but no matter how many times I have tried factory reset, reboot, wipe cache partition, etc, no change, still reboots after 30 seconds of setup.
I tried flashing G920VVRU3BOG5_G920VVZW3BOG5_G920VVRU3BOG5_HOME.tar.md5 with odin 3.10 (not successful with odin 3.09), odin 3.10 was successful, but no change, still stuck in boot loop. checked md5, tried again with same file downloaded from a different source...
Also tried messing around in sidesync, VZW software upgrade assistant, and even kies with no real luck. I am not concerned with root, but hesitant to flash anything other than the OG5 version that is on there now. Just want to get to the point where I can try some of the "samsung account bypass" tricks I have read about like here: http://forum.xda-developers.com/verizon-galaxy-s6/help/bypass-samsung-reactivation-lock-t3250282
Any details I left out? PLEASE ASK, I will happily clarify. I have searched the forum extensively and consulted google.
ANY INPUT VERY GREATLY APPRECIATED as to what steps I should try next. Thank you
Have you reached out to Samsung? Better yet can't the seller just remove the reactivation lock from his account? That should be the first thing the seller should have done prior to selling it. If he doesn't know his Samsung login info HE need to call them...very irresponsible on his part.
Sent from my SM-G920V using Tapatalk
The seller would need to figure out what his Samsung account is. otherwise it's basically a brick.
I appreciate the responses, however, I am not willing to give up yet. I believe if I can get past the reboot/boot loop issue, I can bypass the samsung account lock, as other people have confirmed on the g920v, in the link I posted above.
the seller told me that it was a phone he bought used, and it had the previous owner's samsung account info attached. The seller will not help me, and I do not have the email address or any way to contact the owner before him. Being craigslist, I do not have any leverage for a return to the seller, etc.
I have not tried contacting samsung.
I am planning to try to flash OG9 version next using odin. Then I will try to flash the newest version, OK7
After that I will try to update with kies. If that doesn't work I will try to take it to best buy samsung experience center and see if they can flash anything...
Are there any bootloaders/ custom recovery that I should consider looking into, anything that I may have missed? for 5.1.1? twrp?
Again, thanks for your help, any advice or links to relevant posts or info would be VERY greatly appreciated. Thank you!
From my understanding (while limited) no amount of flashing will remove the Reactivation lock. It's designed to be just that, a lock, that prevents someone who stole the phone from using it.
KIES does not work on the S6, you have to use SmartSwitch instead.
Samsung can't do anything for you.
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.

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
Hello everyone.
I need some help recovering data from a Samsung J7 (2016) with a screen pin. If it's possible, if I can remove only that pin without touching the apps in the phone will be great. I was thinking to format and then pass a recovery app after rooting but I think I will have issue with Google FRP.
Not sure if I go to download mode and root through Odin if I can then remove the pin (or through custom recovery) and do it without USB debugging enabled.
Why I need the data? The owner died few days ago (suicide) few days ago and the family and local police asked me for help to access the phone, so the information is very important.
I tried some things but I'm out of ideas right now. I don't care if the phone have warranty which will be lost.
Also, I'm not doing it for money, I'll do it to help the family.
Any help/idea will be great.
Thanks.
i have the solution

Which video? How if I don't have custom recovery but stock?
It doesn't help and I don't want to f**k the data trying to flash twrp without being sure the phone will boot up
UPDATE:
I have access to the Google account linked to the device. I set a PIN through device manager and tried it after inserting a sim card with internet, but I haven't wait enough and after inserting the PIN I got blocked another 60 minutes....damn.
I can't find if he set a Find my phone through Samsung (I don't know which email he used)
Hi All
I have an S7 Exynos with latest Magisk installed and everything has been working flawlessly till I decided this early morning, for not any particular reason(except my increasing amount of grey hair ), to lock the "developer options". I think I have done the same maybe a couple of years ago though cannot remember how I had solved it.
Obviously my phone was instantly locked.
Would someone be able to link a good working solution with being able to keep data and apps? I am a bit desperate as my work is starting again tomorrow.
Thanks a lot.
look at frp bypass
Costum binary blocked by FRP lock is a protection, whene you do a factory reset from recovery. the only way you get this message is with odin.
this one works for me on s7, s7 edge and s6 tab
Thanks @Dagobert
I will have a look at it now and see if it is not too scary. See my S7 FRP

If you have acces to the phone then backup your data do a factory reset. Then you can flash whatever you want. Frp lock is a google protection with a google account. Whene you do a factory reset from settings you wipe the frp.
What is Google FRP?
FAQ for Samsung Mobile Device. Find more about 'What is Google FRP?' with Samsung Support.
www.samsung.com
I have access to the phone via PC/Odin only. No booting as per image above. I wand to keep Data and Apps
I assume I have to flash stock with home csc to be able to enter the phone again? Then root again, if I so wish?
Yup. Maybee a long shot but try Flashing your former firmware with Odin, using HOME_CSC. I think thats the solution
More info on that in this topic
Help! How to flash without losing data?
Good day! My phone got stuck on breathing Samsung logo after my phone updates. Now the only option I have in mind is to restore factory data. But I have some important files in my phone that is very essential in my work. I know I have read that...
forum.xda-developers.com
hmm., done the flashing with the files plus home csc and it asks for password, which I have entered without success. I know the password and it justs does not accept it.
See the factory reset warning and the FRP lock still being on now.
I'm desperately trying to avoid wipping data and apps.
edit: unfortunately I had to format/reinstall as I could not find a workable option.
Good Morning Everyone
As the title suggests, i am looking to return my S22 Ultra back to stock.
i was on beyond rom for a bit, but too many apps complaining that my device was rooted has forced my hand to return my device back to stock once again.
I flashed the stock rom via odin, then locked my bootloader and wiped all data.
However i am still getting messages that my device is modifed.
Anyone got any ideas how to can truely return to full stock?
Thanks in advanced.
And yes i did do a search on the internet before asking, but i have been unable to find any advice outside of what i have already done.
happend to me, too. But only on the latest firmware. When I flash an older firmware, it won't appear. But after updating again to the latest ROM the message appears
Cheers mate. I'll give that a go.
Also note that if the device was rooted then you triggered the Knox flag and that one CANNOT BE RESET, it's an "efuse" (a hardware component that once changed it's state can only be reset by replacing it, i believe you need to replace the entire motherboard for that).
So, if the application checks the Knox status it will fail.
Here are a few apps that i know that will not work anymore :
- Knox itself (and any app that uses the Knox library/API )
- Samsung Pay
- Samsung Health
- Secure Folder
A few years ago I also had a banking app that failed to worked with a Knox flag triggered (on a Note 8), but after an update it allowed me to use the phone as long as i didn't have it rooted.
