The ultimate phone lockdown showdown!!

I think this is the worst i've seen a phone lock down and i want to see if xda forums have the professionals it takes to bring this phone back from the dead
first thing first.. the model of the phone is a samsung galaxy s6 edge plus (G928T)
PROBLEMS:
The phone boots in recovery.
FRP lock is on (and since the phone cannot boot i cannot enable OEM unlock
if i try to use smart switch/kies I cannot try emergency recovery because apparently the imei and S/N has changed so there is no way i can initialize the phone
its a mess..
"and the error i see when booting is dm-verity verification failed...
need to check drk first"
fyi: im not responsible for this terrible mess lol its not my phone its a customer phone and the customer went to a guy who try changing the imei like a punk and got it stuck like this
The upside is that i can still flash thru odin but i feel like odin cannot help because i cannot downgrade the system OS (due to frp lock on) and im on the latest firmware for this phone
This is the ULTIMATE PHONE LOCKDOWN
all help will be greatful​

Second hand s9 plus, strange download mode, sample device?

I have bought a 2nd hand s9 plus and I discovered it might be a sample/test device (CSC is EGY/EGY/SMP) Everything is working (Samsung account, Knox, fingerprints, etc...) but I am afraid it can be locked or something remotely anytime.
Should I be worried? I have installed the latest Pie update from Odin but my RMM state stayed prenormal even after 7 days uptime.
Note:
My download mode has a strange line
Eng mode : Eng allowed (someone name...)
I didn't see anything like that in any download mode.
Any help will be greatly appreciated.

Don't worry.. the 1st is your region on firmware,the 2nd is your recommended region for your sim and the 3rt is your original region for which phone been made. That prenormal is nothing to worry.

Help with Odin flashing FRP locked SM-T827V

Hello, I was recently given a Tab S3 (Verizon) by a friend, and it was FRP locked. When asked, the friend said that she had no Idea which account might have been on it, and none that she tried worked, so I was stuck. So far I have tried a lot, and most recently, I have been trying to use Odin to flash a Combo file that I found for this model, but it fails to flash, and the tablet states:
Code:
SW REV CHECK FAIL : [aboot]Fused 2 > Binary 0
A couple of questions:
1) What does this mean?
2) Is this because it is FRP locked?
3) If it is, am I SOL?
4) If not, am I SOL anyway with the FRP lock?
I have had some experience with android modding, so I'm not a total noob, but don't take that for granted, I may have missed something very stupid/obvious.
The current firmware is: Oreo/T827VVRS2BRJ1
The combo firmware is: Oreo (I think)/T827VVRU0AQB9
Odin reports FRP Lock is on
Well, I managed to get firmware to flash by getting the same version that is on the tablet currently, but the flashing did not help, because FRP lock is still on. I even went as far as to get a partition table file and completely nuke the nand, which was probably a stupid idea, but nevertheless, even that didn't work to remove the FRP lock. Any ideas?
Thanks, SciFI101
P.S. Also note that the firmware that flashed was not a combo file, I have no idea what the difference is, do I need a combo file to remove FRP?
Flash combination firmware and then remove the google account and delete the Google account on device administration. Flash back original firmware all done.
Which combo firmware should I flash? Any that I have tried have failed with the SW REV CHECK FAIL error.
Also, the stock recovery seems to be shagged, after the blue "Installing updates"/"No Command" screen, the screen goes almost entirely dark, but it is still the same blue screen with Andy in the middle. It still boots into the OS and download mode otherwise. flashing BL and/or AP doesn't seem to fix it

Uptime should be equal to 7days... then oem unlock option will appear but ...... I want another solution date change and WiFi connect is not solution ... If any body knows any other solution please guide me ... I'll be very thankful.....
@ladlabaloch512
Perhaps your device has the same "OEM unlock" block like mine.
On mine I was supposed to wait 7d after turning on dev options.
I bypassed that by
1. switching to airplane mode
2. Setting manually date back one month
3. Restart (still in airplane mode)
4. Turning off airplane mode and let it sync date
and voila OEM unlock option was there.
Perhaps that works on your device as well.

Keep us updated.. I'd like to get my OEM unlock to come out of hiding.. this is frustrsting.. i see all these tutorials for the A02s root, twrp and ROMs and whatnot and I'm itching to get flashing!
Is it possible to flash an unlocked carrier firmware in ODIN and then be able to unlock OEM? Without carrier issues or anything? I'm a little nervous to be the first to try.. and not sure where to find US unlocked carrier firmware or if location even matters... I have the SM-A025AZ (US Cricket variant).. I guess as long as Download Mode (fastboot) is still accessible I could just flash the Cricket version back to the device.. bricked my LG-E980 back in the day.. took me a few months how to get it back up and running with LG flash tool.. i just dont want to repeat that fiasco lol... so anybody got any updates on hacking this OEM (un)lock bs??? Or any idea on flashing some other variant to the device without interrupting carrier stuff??.. seems like alot just to get a damn virtual switch to turn on.. but damnit I need root access! Lol.. about to just exchange this phone for an actual rootable phone.. i disagree with charging for hotspot.. that should be illegal.. getting charged twice to use th same bs internet.. eff that.. i just want Rooooooot!!!
Hello,
I have also been having these troubles, with no way to unlock oem after stock flash, and the closest I've got to finding a solution was this, but I simply cannot find samsung's bootloader unlocking form like it says in the guide. I bought my phone just for a bootloader unlockable version (A025M), and now I am very angry at samsung.
also, since over a 1000 hours have gone by since last post, have any one of you solved this issue just by waiting?

its not only samsung that does this, many other companies like motorola does this. Dont be angry, just try a different device. Also, snapdragon US models (i dont think) arent able to be unlocked. If its a mediatek model and isnt sim/carrier locked, u can try MTKClient

Boot Loop and does not enter recovery screen

Hi folks,
my trusty S3 (SM-T825) got broke unexpectedly. It showed "100% battery" in the morning but was unresponsive. A forced shutdown did reboot the device up to the logo-screen - from where it rebooted again. So obviously it's stuck in a boot loop.
Unfortunately, it does not enter "recovery" either (home) (up) (power). However, it DOES enter "ODIN mode" (home) (down) (power). There it shows me that FRP Lock and OEM lock both are still active. This is no wonder as it caught me unprepared. FRP lock wouldn't be a problem, as I'm the owner of the account and can supply credentials once it boots up again.
Everywhere it is STRONGLY advised to turn off OEM lock before flashing anything to not make it even worse. This renders the device essentially dead, right?
The device is still as original as it can be.
Any chance I can revive it or does that more look like a mainboard problem?
I already have ODIN and I even have an actual 4-part "Original ROM" for my region (Samfw.com_SM-T825_ATO_T825XXU3CTD1_fac.zip), but maybe TWRP and Lineage would be the better options.
Before I just go and make things worse, I'd like to ask for a qualified advice ;-)

Afaik you should be able to flash stock with OEM lock active BUT idk if FRP will block flashing process.
If that happens it's imo afterwards in the same state as before so at least it won't worsen it.
Gonna loose all your data anyhow.
Got Smartswitch? This might help as well.

You can't replace recovery without OEM unlock.

Next turn ...
I tried flashing TWRP into the AP slot with SamFW FRP-Tool (ODIN). This worked so far but got me a note on the tablet "custom recovery blocked due to FRP lock".
Checking boot on the tablet - as before. Boot loop.

So maybe the firmware revision is different to the currently installed one? The latest file is from 2020 and since I did the usual OTA updates, this should be the version installed. But even if not, it sould not matter to upload a newer one, right?
Anything I can check?
So then obviously "Game Over"
Another piece of expensive waste that otherwise could have served well for years to come. Yes I know, selling something just once is an inferior business model to repeatedly draining my account for the same service.
