Help with Odin flashing FRP locked SM-T827V - Samsung Galaxy Tab S3 Questions & Answers

Help with Odin flashing FRP locked SM-T827V - Samsung Galaxy Tab S3 Questions & Answers

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

[J5108/J7108][GUIDE]how to root the Galaxy J5/J7 2016 models J5108/J7108

Hi Evryone.
Because I didn't found CWM or TWRP Recovery or any root method for the galaxy J5 J5108 and the J7 J7108, I made a pre-rooted firmwares for those models.
This firmware base on the hong kong firmware which include the Google apps, this a full firmware exactly like the original, except the root.
After flash you will see the SuperSU app in the app drawer.
Also, this firmware contains the bootloader from the china firmware which doesn't have frp lock.
The root include the binary files in the system, and a pathed boot. (from Android 6.0 or samsung 5.1.1 pathing the boot is necessary for the root work properly)
Flashing this firmware will not wipe data automaticly. you should not lose anything.
This file will work on any firmware/baseband/csc. you can always flash it like a stock firmware.

Installation instructions
Before flashing check the CROM Service status in Download mode, if it locked you will need to unlock the bootloader first with the app attached.
Install samsung usb drivers from here.
Download the self extracting 7z file above and extract it (just double tap) to some folder, you should receive a tar.md5 file.
Open odin 3 (attached in the zip)
Put the tar.md5 file in AP.
Put the device in download mode. (vol down + home + power button, and then click on vol up)
Connect your phone to usb and wait for odin detect the device.
Click start.
After it finish choose reboot system now in recovery.
Enjoy.

Thanks a lot avicohh. This was simple and painless. I now have google services on my mainland China phone. And root too! And like you said - I did not loose anything.

well now i am stuck. I enabled my google account, installed and updated my apps through google play, shutdown and now I can't boot. The message in red on the top of the boot screen is:
"KERNEL IS NOT SEANDROID ENFORCING
Custom Binary blocked by FRP lock."
I also cannot reflash the same HK rooted firmware using Odin
apparently I should have enabled developer options then enabled OEM unlocking before rebooting. But I didn't know that so for now I am bricked
Also apparently, the fix for it is to reflash the original firmware using Odin. I am now downloading the firmware from http://updato.com/firmware-archive-select-model?record=1F170CA05E5611E6B055FA163EE8F90B but it is still another 2-3 hours to complete the download (yes, poor internet connection here.)... So I'll see how that goes...

OK, that didn't work. Now the message on the download mode screen says:
SW REV. Invalid type.
FRP is enabled, not allow download non FRP bootloader binary

Well..
I just recently had the same problem in another device.
I don't think the "Oem unlock" has nothing to do with this. the problem is that when you're adding Google account the frp (factroy reset protection) is automaticly enabled, and then it blocks the pathed boot.
The reason reflash the original firmware didn't work for you is because you tried to flash the china version, that doesn't have google service and also doesn't have frp in the bootloader. (apparently once frp is enabled this kind of operation is not allowed because you are actually trying to remove the frp lock by flashing bootloader..)
I think the solution will be to flash the original hong kong firmware with the frp bootloader and original boot. (or just the original boot)
http://updato.com/firmware-archive-select-model?record=5C13445B54D811E6B055FA163EE8F90B
Then, try to enable the "Oem unlock" option and finally flash the rooted firmware again.
maybe it will work, I'm not sure about it but I would like to know.
If this won't work, I'll try to combine the rooted hong kong firmware with the non-frp bootloader from the china firmware.

Thanks so much for replying avicohh

This makes sense. I was actually suspecting this and was considering trying the 6.01 HK version since that is the only one I could find: http://updato.com/firmware-archive-select-model?record=5C13445B54D811E6B055FA163EE8F90B
Now that you've posted a link to your original 5.1 HK firmware I'll try what you suggest. I'll wait to get home before I start the download.
But I still wonder if the 6.01 would work on my phone?

It's a mistake.
This link above is 5.1.1, not 6.0.1.
There is no 6.0.1 fro this model for now.

yes, I see, the website says its 6.01, but its actually 5.1.1. How do I know? BECAUSE IT WORKED!!! It took 7 hours to download but when I got up this morning it was done, I flashed and it worked!!!
I'm going to read up some more on this FRP business before flashing the rooted version again. My old phone (very old) had no such thing. I'd never heard of it till this unpleasant way of learning about it.

Hi guys.
Thanks for your replies.
I've just checked it now on another device.
As it turn out after a several tests, this "custom binary blocked by frp lock" problem occurs only if the oem unlock option is disabled.
Here is what I did, step by step:
First, I enabled the oem unlock option and then I added Google account - nothing happened. frp lock in Download mode is still off and everything working fine.
I removed the google account, turned off the oem unlock option and finally added the google account again - frp lock in download mode immediately switch to on, and when I tried to restart, the device has stuck on the boot. (custom binary..)
I flashed stock firmware (from the link above), the device now bootup normally but the frp lock in download mode is still on. (I didn't remove the google account yet)
Final check - I enabled the oem unlock again, and the frp lock in download mode switch to off.
So..
I can safely say that all you need to do is just enable oem unlock in developer options, and then flash the rooted firmware.
Anyway, to be even more sure, I made a new firmware with the china bootloader, frp now is not even exist in download mode.
You can download the new firmware from here

Hey, How do I enable OEM unlock when I can't even boot my device. it simply refuses to boot.

Hi
First flash the original HK firmware from here. the device should boot up normally.
http://updato.com/firmware-archive-select-model?record=5C13445B54D811E6B055FA163EE8F90B
Then, enable oem unlock.

Thanks for making the root version of mainland firmware. I'm going to stick with the HK version as I want to have google services. and thanks for testing the oem unlock
I informed myself some more about FRP and OEM unlock and I am now feel safe to use the rooted HK firmware. Except, I came across one note for which I want further clarification before proceeding. The note is from http://www.androidcentral.com/factory-reset-protection-what-you-need-know and it says:
"A couple notes need added here. This doesn't undo Samsung's (or anyone else's) version of Reactivation Lock. If you've enabled data reset protection through your Samsung account, you'll need to turn that off in your Security settings. You can find the switch under the "Find My Mobile" section."
So, I want to be sure I don't have this samsung Reactivation Lock enabled. and that I am in no danger of it auto-enabling. I believe I am safe but I would like to know if anyone has more clear information.
What I do know is before I flashed to HK ROM, when I went into download mode, there displayed a setting:
"REACTIVATION LOCK: OFF"
now, using the HK ROM, it is gone, but in that exact same location is the setting:
"FRP LOCK: OFF"
I think, that means the mainland version of the FRP lock (Samsung Reactivation Lock), is now replaced with the google FRP lock and as I don't have to worry about the samsung reactivation lock anymore. Is that so?
even so, as the article says, I look in "Settings" >> "Lock screen and security" >> "Find my mobile" >> log into Samsung Account when prompted, then it does not display the "Reactivation Lock" option that is shown in at least one guide that I found. I really think this is further proof I don't have to worry about Samsung Reactivation Lock. Can anyone confirm?

Yes I can confirm.
But pay attention that because of the FRP, is not possible to make a pre-rooted firmware for Android 6.0 and above or 5.1.1 Samsung devices, from firmware contains FRP protection like the HK one.
From those android versions (and above), a pre-rooted firmware (or any root method) must include a patched kernel.
Due to the FRP protection, once it turn on, it detect the custom kernel (boot) and not allow the device to boot. (custom binary blocked by FRP lock)
That's the reason I had to replace the HK bootloader which contain FRP protection, with the China bootloader which contain the Samsung reactivation lock. (instead of FRP, because china firmwares doesn't include any google services)
I don't know what the policy of the Samsung reactivation lock, about custom kernels.
And also I don't know if the Samsung reactivation lock turns on automaticly if you are adding Samsung account. (Like the FRP lock)
And one more thing, I beleive most people don't use Samsung account at all.
So after all this,
If it come to decision what to use, the FRP lock or the Samsung one (depends only in the bootloader), I'm pretty sure that in this case (custom boot), the best is to use the Samsung lock, and just dont add Samsung account, or add Samsung account if needed but turn off the Reactivation lock in the Find my mobile settings.
I hope it help you a bit.
Good luck.
btw, If you can check the Samsung lock after root and report here, it would be great.

Oh, at first I thought you meant you rooted the mainland firmware. Now, based on your later post, I believe what you did was to put the mainland bootloader in the rooted HK firmware. Is this the case? If so, that means I can still have google services, and root, and no possibility of FRP issues because its a mainland bootloader. OK, I will try tonight. The Samsung reactivation lock is off by default. Even adding a Samsung account does not turn it on, you have to go into "find my phone" to turn it on. So it should be safe. I will confirm tonight after I download your new firmware.

Yes, this is exactly what i did.
Thanks for testing the samsung account. so it is pretty safe.

yes, this new version with mainland bootloader is good. It seems almost impossible to lock.
Now when I go to download mode, there is no more "FRP LOCK: OFF". in its place is "REACTIVATION LOCK: OFF".
Just for fun I tested by going inter developer options and turned off OEM unlock - then I tried to reboot = success. Enter download mode = still "REACTIVATION LOCK: OFF". Of course I turned it back on again after the test.
and in settings, find my mobile, there is still not a setting for "REACTIVATION LOCK". I have seen an example on the web that this reactivation lock setting should be at the bottom of the options under find my mobile. So, actually now I cannot find any way to turn on the reactivation lock - this is good, its what we want.
Of course to even enter the "find my mobile" section I can do nothing at all (in fact it does not even show me what the options are) untill I give my samsung account credentials. Once I give credentials I can see the options but there is no option to turn on reactivation lock. There is just one thing, maybe, is that in "find my mobile", there a place that says: for more information go to findmymobile.samsung.com. When I go there I have 2 options:
-1) FIND - Find, Lock, Wipe my device
-2) PREPARE - Ready device for Find my Mobile
this "prepare" option I am afraid to try, I am afraid it may be the one to enable reactivation lock. Clearly it is not required to actually find my mobile because I just click the "Find" button and it it finds it for me. So, what would be the use of "prepare"?
At any rate, we know that just creating a samsung account does not activate the lock. I never had a Samsung account before. When I set up this new phone I never did enter developer mode to turn on oem unlock but i did create the samsung account. It was after that I flashed version 1 of avicohh's rooted firmware and when I went into download mode, it said REACTIVATION LOCK: OFF, so creating the Samsung account does not turn it on.

The 101 thousand thread with issue with S7 unable to unlock FRP despite various FLASH

Hi Guys and Gals,
Sorry if this is one of hundreds similar questions regarding the S7 FRP but I believe I have exhausted methods listed on advice posts, this is kinda last resort.
Sadly, my Grandfather recently passed away and he left my mum his S7 G930... my mother then had a friend do a factor reset on the phone but was unable to login into the phone once it was reset as it was asking for previous owner. Yep, they didn't remove his account before doing so, nor did they enable USB debug and I am unsure if OEM lock is disabled or enabled.
Following the advice of the post on here labeled: [GUIDE]All-In-One(stock FW/CSC/ROOT/TWRP recovery/FRP unlock/PIT/unbrick/bootloader)
1. [ODIN FAIL] I tried to flash using CF-Auto-Root (cfar_samsung_sm-g930f_heroltexx_nrd90m.g930fxxu1dqg1_t0) but get the issue custom binary is blocked due to FRP lock.
2. [ODIN PASS but...] Then I followed the advice of downloading the stock firmware G930FXXU1DQG1_G930FOXA1DQG1_BTU and flash just the BL (bootloader) and CP (Modem), sadly... after resetting the device it boots up still asking for the previous owner details which obviously we don't have.
3. [ODIN PASS but...] In the same post it says if the above fails simply FULL STOCK flash which using G930FXXU1DQG1_G930FOXA1DQG1_BTU. I select BL, AP, CP and CSC and ODIN passes without fail but rebooting the default it starts to setup the install and applications, then get the Google previous owner message.
4. [Smart Switch FAIL] Reports USB file transfer is not allowed.
I did read somewhere that you can pair a Bluetooth device after hanging up on emergency services, I'd rather not even attempt this method is unethical.
Is this phone a bin job? or is there anything else I can try? would be nice if my Mum could have a upgrade and something that was his.

Problem flashing the combination file

Ok, so, I have an S9+ model G9650ZHS6CSK4 (Android 9.0, I only found one firmware version that matched my bootloader version and it was a 9.0 one)
It took me a long while, but I've downloaded this combination firmware G9650ZCU6ASJ2 (FA80)
Everything fine there, but, when I go to Odin and load the combo file in the AP slot of Odin, connect the phone and then click start it immediately stops, and in the phone it says:
FRP is enabled, ignore PIT download.
FRP is enabled, not allowed to download non-FRP abl binary
Here is the log of Odin when it happens: https://m.imgur.com/a/dEAwC26
What am I doing wrong? I know the phone is FRP locked, I want to bypass it.
Can you guys help me?

an newbie need your advice and help!

hi all,
I have Samsung SM-G935W8 (in Canada), bought used from someone. recently, try to play with android, and realized the phone PDA was G935UUEU4BRD1, and model was SM-G935U which is different from the model that showing on back cover. think the guy flashed a different rom for this phone.
couple days ago, I did hard factory reset for no reason, and get google account locked. then search online and learning how to fix it. seems like need to flash combination rom --> use tool bypass frp --> flash official rom to solve this issues.
i downloaded many combination firmware and all failed on odin flash. until i use one that allowed me to flash and success to open the phone as Factory Binary. But, I noticed the phone model changed to SM-G935A, which is AT&T firmware. the android version is 6.0.1, when I try to run program to do FRP bypass, no luck, think that because I can't turn on OEM- Unlock option(can't find it on developer option tough)? or bootloader locked?
now, I can only flash official rom that from AT&T, and android 8 that I can find it. if the phone can be fixed FRP issues, model change to G935A is fine, I dont care that model, I dont use the phone for call, only for wifi and camera. and maybe later can play flash to other model of ROM. not sure if possible.
current, the working combination rom I flashed is PDA : G935UUCUBATA1
ADB FRP to bypass FRP (not working)
and flashed to AT&T rom PDA: G935AUCUBCTB1_G935AATTBCTB1_8.0.0
FRP still not bypassed, and stuck on google account validation screen. any advice how and what tools can bypass FRP for this phone now model is SM-G935A? thanks in advance!

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.
