Recovering from FRP Lock, did I brick my phone?

Hi all,
New user here, not much experience rooting or messing with firmware for phones. I was following the guide on how to flash the SM-935U firmware to the verizon model of the Galaxy S7 Edge, and may have bricked my phone. Here's what I did.
Followed the guide to the letter.
Powered off phone, booted to Download mode
Fired up Odin, selected the SM-935U firmware files, and clicked start.
It gave me an Auth error, which research revealed means that I forgot to turn off Reactivation Lock. I figured, "Fine, I'll just disable it. However, I can't get the phone to boot again. Every time I leave download mode, it boots into Android Recovery, where, no matter what I do, it just reboots into Android Recovery. I can't Wipe anything because it can't mount /system - probably due to Reactivation Lock?
I've been research and researching ways around this, and everything I find just points back to flashing it with the stock firmware. But then I read that you can't even do that if Reactivation lock is on, because Odin will still fail with the Auth error. So, I can only get it to boot to recovery mode, and I can't flash it with anything?
I did read somewhere that if I choose to wipe the phone's EFS with Odin that it should override activation lock, but then it clears the phones IMEI, which is an even bigger mess, isn't it?
I feel like I have to be missing something... since it never did the wipe, why is it that I can't get past the recovery mode. Shouldn't I still be able to get into the system somehow?
Does Anyone have any thoughts or suggestions for me? I'd really like to not be stuck with a permanently bricked S7 edge if at all possible....

Solved
Just wanted to post this to help anyone else who might have this issue. Turns out that you can flash the stock firmware, as long as you're flashing at least the same version or newer of the stock firmware as what the phone was running prior to getting stuck in recovery mode. It shows you what version it was running in the recovery mode at the top.
So for me, I googled the exact firmware version that recovery mode said the phone was running, downloaded it, flashed it with ODIN, and it worked just fine. Had to choose to wipe with the recovery mode after I flashed it, but then it booted like normal. - Then I enabled OEM unlocking under the developer menu, and tried flashing the U firmware again with ODIN, and it still failed with the auth error. Huh.
Turns out (maybe I wasn't doing it right or something) that you can't flash older versions of the firmware to the phone. But, as long as OEM unlocking is enabled, you can flash the U (unlocked) version of the current firmware to the phone and it will take just fine. Hint: I was able to determine the "version" number by looking at the last 4-5 characters of the build number... the verizon version I was running for my SM-935V was: VZW-G935VVRU4API3 - So I googled the API3 firmware and found the U (unlocked) version for my carrier (I happen to be using T-Mobile) on this site: https://samsung-firmware.org/model/SM-G935U/ and found the zip file name which was TMB-G935UUEU4API3-20161011161050.zip, googled that, got the rapidgator link, downloaded it, and that flashed just fine to the phone, and now my T-Mobile SIM works perfectly in what was previously the SM-935V, which now identifies as an SM-935U in settings. It's beautiful.
Also, you need the PIT file, but I was able to use the PIT file for the phone model number (again, found at the top of the android recovery menu), which for my phone was: HERO2QLTE_USA_VZW.pit (googled that and got it off androidfilehost) - I was able to use that PIT file for the T-Mobile U version of the firmware and it worked just fine.
Hope this helps someone.

downgrading problem oreo to nougat s8

hello,
i managed to get the phone back to get in download mode. stock everything, no root whatsoever. my goal is to root my phone and i have experience doing so but i guess i was just unlucky this time.
i tried searching allover the internet for a fix, searching xda etc.
first off: my device is running oreo 8.0 and it's type is G950FX.
I want to downgrade to 7.0 because FRP lock is on, i did turn on oem lock before starting however i am unable to log in to my old google account connected to my phone.
when i try to flash any bootloader i get SW REV CHECK FAIL DEVICE 2, BINARY 1. i tried almost any trick in the book like downloading 7.0 from sammobile, flashing using odin.
the things i run into when flashing are:
1.can't flash the bootloader, probably because of frp lock.
2. when i don't flash the bootloader for 7.0 i get dm-verity error 0x2.
3. when i only flash 8.0 oreo pda & csc and then flash 7.0 pda on top i do get to boot but i get encryption interrupted error.
4. i am able to boot in 8.0 but can't get past the frp.
i'm out of answers, i really hope anyone can help me out of this situation as i want to use my phone.
Help is much appreciated!
edit: i tried flashing multiple versions of android 7.0 but i keep getting sw rev check fail bootloader device 2 binary 1
i basicly want to do this, a downgrade: https://forums.androidcentral.com/s...s8-plus/878062-how-downgrade-oreo-nougat.html
the problem is i didn't sign out of google or samsung accounts before resetting to factory

You can't. You have a new bootloader v2.
A simple search gives you this answer, if you have u2 and CRED bootloader installed you are stuck. No way to go back anymore.

i'm on u2 and CRED bootloader. i did search for this indeed but i didn't want to give up.
do you think there will be ever be a way to get back into my phone again?

If you have FRP lock good luck. I haven't seen a way yet.

I know it's been 5 months and you've probably either gotten rid of the phone or it's sitting in a dusty bin somewhere, but have you tried Galaxy Reaper? It's a pretty legit FRP bypass tool.
Edit: Scratch that. It's apparently been patched since I last knew it to work. Just wanted to double check, and sure enough..

How to recover Galaxy Tab A 10.1 (2016) without factory reset?

Hello, I need to access Galaxy Tab SM-P585 which belonged to a friend who has passed away, so pattern, pin and Google account info are unknown. Also firmware is original from Samsung, developer mode is disabled and OEM locked. The only options available are recovery mode, where I can do a factory reset or enter sideload mode, and download mode. I have found this guide https://forum.xda-developers.com/showthread.php?p=49666433 to bypass pattern but custom recovery is needed to use either Pattern Password Disable or Aroma File Manager methods. Then I have tried to install TWRP via this guide https://forum.xda-developers.com/ga...covery-official-twrp-galaxy-tab-10-1-t3473023 via Odin however device returns error "Blocked by FRP Lock" which from my search is either Google or Samsung https://www.samsung.com/us/support/frp/ Is there a way to access this device without factory reset?

Try and reflash it using Odin with a stock firmware, that might work. Get your firmware from Sam Mobile firmwares. Just make sure you get the exact corresponding firmware...
Let me know how you go...

Thanks, I've looked up for SM-P585 model but found only firmwares for ME and Africa. Tried with South African version but got SECURE CHECK FAILED (BOOTLOADER) error, which I believe is because it is not exactly the same version. From the recovery menu I've found out that I need 7.0/NRD90M/T585XXU2BRB2 version (multi region) so now downloading from samsunggalaxyrom and getdroidtips. I'll see how it goes with either one...
P.S. From the instructions "Use CSC_*** if you want to do a clean flash or HOME_CSC_*** if you want to keep your apps and data." so I'll use HOME_CSC_ file to keep apps and the data.

If you use CSC it will wipe the device along with any security measures set up and basically put the device back to factory setup.

Unfortunately HOME_CSC didn't work, security settings were still there, so I have applied CSC. However now FRP requires me to logon using original Google account, even after factory reset, so this functionally means that device is only for a dumpster?

Not at all, FRP can be bypassed.

Sm-t280 frp locked binary

So long story short I was intoxicated and for some reason disabled OEM in debugging then sometime later I restarted my tablet to get the frp binary locked. It has a custom rom with twrp I absolutely need the data off of this tablet and the only way I see is to reinstall the default os through Odin but that wipes the device I need a method to get the data off of the tablet or a method to bypass frp entirely it would be mighty appreciated if I could have some help

Why don't you try a backup in TWRP?

Reinstalling the stock firmware with Odin won't wipe the device.

It's difficult to say if you can keep your data. The binary FRP lock is quite different that the average FRP lock that's associated with the Google sign in. Usually whenever you trip the binary lock it's because some firmware was installed such as a Root or a ROM that was flawed or invalid. It's an overstacking of binaries and therefore you get a "Custom Binaries Blocked by FRP Lock" notification. I've had this problem on another varient of the Tab A, the Galaxy Tab A6 SM-T580. I have found about four diferent variations of this. You may not have turned off OEM because in Binary lock it will act like you have. Possible reason to think that is the way it acts in Download Mode where you can't seem to flash anything especially the official firmware. Sound familiar?
Version 1. If you try to go to Recovery you get redirected to a screen similar to the Download Mode. In the upper left are red lettered "Custom Binaries Blocked by FRP Lock.. Download Mode is accessable but won't initialize when trying to flash stock firmware. Binary 4 FRP Unlock file was accepted and flashed in by Odin3. Stock firmware installs afterwards.
Version 2. Device is stuck in bootloop. "Custom Binaries Blocked by FRP Lock" appears on Logo screen. Recovery and Download Modes are so far, useless. Binary 4 FRP Unlock used, no positive results. Binary U 4 used. Positive result. Stock firmware flashed in afterwards.
Version 3. "Custom Binaries Blocked by FRP Lock" appears on Download Mode which either stalls right after or fails to initialize. Binary 4 FRP Unlock and Binary U 4 yeild no positive results. (This ones on it's way to me).
Version 4. "Custom Binaries Blocked by FRP Lock appears on Recovery Mode. Download Mode useless. I'm currently following this one.
Solution: I don't know if the one I have will work, they may be device specific. Research for a "SM-T280 Binary 4 FRP Unlock" which I couldn't yet find.

Nothing needs to be done except install the stock firmware.
The device hasn't been reset so no need for any kind of bypass.
FRP has kicked in purely because unsigned software is installed.
Replace the unsigned software with stock and it'll boot just fine. Data fully intact.

I hate to argue with you but that wasn't so easy with mine. While in Binary FRP lock I, along with a few others that have the SM-T580 or the SM-T585 couldn't use Download Mode to flash in the official stock firmware. Trial and error followed. The solve was first I had to flash in the Binary FRP Unlock and then I could flash in the firmware. With another device the owner tried the Binary Frp Unlock which didn't fix it. Later he flashed in the U4 Binary and that worked for him. I passed the info along to some others in the same predicament and it helped them. So I don't know what to tell you but what you're stating is not always applicable.

Trust me, I have 3 of these devices. I've bricked them, frp locked them every possible way during development for this device.
The T580 is a different device and may be more difficult to bypass if and only if FRP has kicked in because of a device reset.
However for EVERY Samsung device that has simply had non stock software installed the only fix that's required is to install the stock firmware.
This is the case on all the Samsung devices I own and I have quite a few from lollipop to Pie.

Wow, you're on a roll ain't ya? Hey ASHYX, dont misjudge me because of my stats you see here. Over a decade ago I was stacking ROMs into my HTC-G1. 3 decades ago I was an Electrical Engineer and Sonar Operator in the Navy. Let me tell you point blank, you're mistaken! Normally you would think you can just flash in stock OTA firmware into the device via Odin3 and you get to return to normal. Well that wasn't the solve for this. This was a new one to me also. If you think you're so right on what you say I'll be more than happy to point you in the direction of some XDA visitors, two of which are still Binary FRP locked. You can try telling them what you just told me and they'll probably call you a blooming idiot. No offense but you could try reading it properly which might help.
I said, [QOUTE] " While in Binary FRP lock I, along with a few others that have the SM-T580 or the SM-T585 couldn't use Download Mode to flash in the official stock firmware. [END QOUTE]
Take my word for it, the method you stated was already tried AND DID NOT WORK!
If you want to insist you're all that, here ya go, these people need your expertise in development

Data loss when flashing stock firmware.

That depends on which stock firmware you're using. Typically what you get OTA (over the air) is the same as the 4File Official Stock Firmware. These are the 4 files that go into each section when using Odin3 to flash firmware. BL is for the Bootloader which controls security, start-up and recovery. AP is Android Partitioning, CP is Cellular Processor. Now let's talk about the CSC. file. The 4File contains two CSC files, one is listed as HOME CSC. If you flash the CSC file you will lose your App data. If you flash the HOME CSC you do not lose your App data.

Thank you for confirming I won't loss any data upon installing the original ROM I did just have a custom ROM installed I was super concerned that I would lose all the data upon installing the original ROM thank you so much <3

Depends on which custom rom you had installed? If it's stock based on lollipop then you should be fine. If its lineage then it may not boot without a data wipe.

Yeah it was just stock lollipop with a root. Will that cause an issue or am I good to continue?

Props to you thanks for the knowledge it worked flawlessly I mean kinda half way through it did say erasing and I kinda **** the bed and got scared because I really needed the data off of there but my man you are right just flashing stock ROM worked flawlessly everywhere online says it will wipe the device but it didn't. Thank you so much for your fantastic help <3

Hi! I've inherited a SM-T590 (among various other devices) from a deceased relative and try to figure out how to unblock them. I flashed the engineering image and turned on ADB but I don't see how to get rid of the FRP from there. What would be the next steps to disable the FRP entirely?
Thanks!

Once you flash the eng ROM, which you have, go into developer options and enable OEM unlock. Then factory reset within the settings. After that you can flash stock and frp will be disabled.

That worked! Thanks a lot!

Hello,
I know this thread is old. I have almost the same problem, except this is a familly kid who forget his lock screen password, and he used a dummy email adresse to create google account... And android version is 10, not 9.
So we did a factory reset from the recovery menu. But, now, we have to enter the google account, and of course, he doesn't remember.
I tried some (non trusted) tools as samsung frp tool, but not working. I tried a combination rom (i don't know if this is the good one), but in the download mode, the device tells me that :
frp is enabled, ignore pit download.
I tried to flash latest version 10 stock rom, but no change.
Is it worth to try to flash with a stock rom version 8 or 9 ? But to get these roms, i have to pay, but no garantie that this will work...
The device is not in debug mode, of course, and oem locked.
In the second post of this thread, there was a google drive link, but it's dead.
Do i have to put this galaxy tab a tm-t590 to the trash, or is there some hope to unlock it?

Finally did it.
I downgraded using odin in Android 9 using a stock rom, for 2.99$.
https://samfrew.com/fr/download/Galaxy__Tab__A__/gi1r/XEF/T590XXU3BSG3/T590OXM3BSG3/
I tried again samsung frp tool that I trust now .
I followed this video:
But the step *#0*# didn't work. So i tried to launch some apps from the web launcher.
I didn't remember exactly how I did it, but I succeded to create a new google account.
I restarted the device, and and i'm now in android. I activated debug mode and disabled oem mode.
I will try to flash something new and maybe alternative firmware.
I don't know which, but I will search here
