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.

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.

So, I've done this before, and I've never bricked a device until now.
I tried installing a custom rom for my Galaxy S3 on Verizon, but when I restarted, it says this:
System software not authorized by Verizon Wireless has been found on your phone. Please turn off your phone and go to the nearest Verizon Wireless store for help.
I can't get into clockwork, or any bootloader. Any attempt to do anything brings this screen up.
Now, I can get into the Odin downloader. (Power, volume down and home). But, I can't figure out how to get a Rom to load. This is where I am stuck. I have downloaded a few roms, all stock, but none of them want to be recognized. I have no idea where to go. I've been downloading stuff for 5 hrs and nothing has worked, so now Im going to the forumns. Any help is appreciated.
I have the Verizon i-535 Galaxy SIII.
You did not brick your phone you failed to unlock your bootloader. There are 2 guides in the android dev section for rooting.
http://forum.xda-developers.com/showthread.php?t=1974114
Odin back to stock and next time after rooting make sure to use EZUnlock 1.2 to unlock the bootloader BEFORE loading a ROM
Hey guys firstly i want to apologize if i'm on the wrong forum.
I have screwed up and i hope you guys could help.
I have a Samsung S6 that worked perfectly, but i wanted to sell it and buy an S7 and so i have done a "hard" factory reset by pushing Vol up, Home, Power buttons. Turns out i had to do a "soft" factory reset first.
Now when i tried to sell my phone with all parts and documents i have failed!
It turns out that the phone asks for my Samsung ID but obviously i can't remember an ID that i have created more than a year ago that was of no use to me!
I think i still have warranty but that is my last option for something like this, i have not rooted this device it runs on marshmallow.
What can i do to fix it myself?
I haven't tried flashing it with a stock rom simply because i fear that that will trigger KNOX, even though i'm desperate to fix this, i haven't crossed that border of despair.
Guys please help, i'm counting on your replies.
Thank you.
Flashing a stock rom that was made for your phone will NOT trigger knox. You can use samfirm and odin to do it

Thanks for your reply, do you mean from sammobile? Also i do not remember what version if marshmallow i was running, is there a way for me to figure it out now?
Okay i figured out what version of marshmallow i was running simply because i had put updates on automatic so it must be the last 6.0.1
However i do not know anything about samfirm i have used odin before on my s4 like 3 years ago, and i only used it to root my s4.
Could anyone please help me out?
Btw, if i successfully put a stock firmware on it throigh samfirm and odin, will it remove my email? Or is it omly worth a try?
Are you certain that it will not trigger knox?
Okay i tried flashing the same firmware unto my devicd but it seems that i can't flash anything because Reactivation Lock is enabled.
I didn't enable it (at least i don't remember) mayve the marshmallow update enabled Reactivation Lock?
I'm almost at the point of throwing my phone into a wall, it's getting close.
Did you figure it out. I'm in the same boat with my S6 edge
I'm feeling like an idiot at the moment. I acquired an S8 today and was planning on giving my old optus acquired S6 to a friend. Not properly following any guides I managed to do a factory reset on my device. Only now it seems to be stuck on the Samsung boot up logo. Not sure what to do from here. Original plan was to root it and have a clean slate.
Any guidance or help would be more than appreciated.
Disregard this.
I managed to get my phone into a download screen and acquire new firmware which I installed via Odin3. Phone is now functioning again, minus all the forced software from my original carrier. Feeling good, even though I probably just lucked out.
Thanks anyway.
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.

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

Do you have acces to the phone?

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?

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

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.
