FRP Lock, OS blocked, Smart Switch doesn't recognize phone for emergency recovery - Galaxy Tab S2 Q&A, Help & Troubleshooting

Hi everyone. Last week I tried to root (successfully) my Tab S2 to make it work with Samsung Gear Smartwatch. Using an application I changed the "model-name" of my tablet from SM-T719 to SM-N910F (Note 4) to make it recognizable by Gear.
My father accidentally disabled "OEM unlock" and then, when I've rebooted it, it was written "Custom binary blocked by FRP lock".
I tried to install the stock ROM (different versions of it) using Odin, but it didn't work (it have always stuck at "system.img.ext4")
Besides, I cannot install TWRP Recovery because when I try to install it via Odin the phone says "SECURE CHECK FAIL: recovery" and "Custom Binary (recovery) Blocked by FRP Lock"
My recovery mode doesn't let me install anything ("Update from external storage is disabled")
So, I'm not able to install the OS. Can anyone help me?

Are you under warranty?

No, I'm not because of having rooted it. The repair center says that I have to change the Motherboard. I'm not sure of this, is it possible?

Post a screen shot of odin.
It seems like you also rooted. FRP is reporting a modified binary, either custom recovery or modified boot image.
Either way its not necessary to flash the system image to remove the FRP lock.
However it will fail dm-verity checks if you've modified the system partition.
Boot and recovery can be flashed without the system image.
Do that first and report back.

How can I flash boot and recovery without system img?
P.S. My recovery mode doesn't work, debug and fastboot neither. I'll send a screenshot of Odin

You are no longer FRP locked according to your screen shot. Binary is now official.
However as said previously system is modified and likely won't boot due to dmverity.
You should be able to boot to stock recovery.
Can you post a screen shot of odin when trying to flash the stock firmware.

It's failing because you are using the wrong ODIN version.
3.07 doesn't support meta data.

Well i am having a similiar Problem.
I am running Lineage 14.1 with TWRP and Magisk/Root.
Yesterday i flashed the latest Lineage nightly, reboot worked without problems.
This morning i started my S2 and i also got the message "Custom Binary blocked by FRP - Secure Fail: Kernel".
I only can get into Download mode. Trying to go into recovery mode i get the message again but with... Secure Fail: Recovery.
Any solution without flashing the Stock Rom?

You will at least have to flash stock boot and recovery images.

I feared so
Lets see where i can find stock boot and recovery..if not i have to download the whole ROM. Slow!!
Any idea where this problem came from? Havent changed anything in the developer settings (OEM, etc)

It always stops there, I let it continue for one hour but nothing happened.
I don't know, is it possible that "FRP Lock: On", "Warranty Void: 0x1 (4)" or "Qualcomm secureboot: enable (CSB)" are responsible of this?

Don't use long USB cables either as these cause issues.

I've just tried with the original one, unfortunately nothing changed
Then I tried to flash TWRP recovery and this is what I got

You can't flash a custom recovery or kernel while FRP is on.

[RECOVERY][ROOT][TWRP 3.0.2-0]Galaxy A8 sm-a800i - Exynos5433 -UPDATE 5/4/2016

Unofficial original release -TWRP recovery for the SM-A800I, Exynos5433
UPDATE 5/4/2016: TWRP 3.0.2-0 released
SEANDROID warning fix.
https://twrp.me/site/update/2016/04/05/twrp-3.0.2-0-released.html
TWRP is now v3.0.2-0
You flash this at your own risk. Please ensure you have the stock ROM to hand downloaded from SAMMOBILE in case of problems. This will trip the knox counter.
UPDATE: 12/3/2016
New feature available in TWRP 3.0.0-0 is system image backup and restore and factory image flashing (see TWRP changelog for details)
Basically this means factory images from the official firmware can now be flashed with TWRP instead of ODIN. I have extended this feature to include BOOT, RECOVERY, SYSTEM, CACHE, HIDDEN and RADIO(MODEM) partitions.
This feature can be found under INSTALL >> INSTALL IMAGE >> select image to flash >> select partition.
NOTE: To flash the modem, first it needs to be renamed to modem.bin.img
F2FS support added.
Internal SUPERSU root option removed. This is to prevent boot loops on 5.11/6.0 devices
Instructions:
Flash with ODIN 3.10.7 in the AP slot.
Uncheck Auto reboot.
Load the respective file below into the AP slot and hit start.
After flashing immediately reboot to recovery by holding POWER + HOME + VOL DOWN.
As soon as the screen goes blank change to VOL UP whilst still holding the other buttons.
You should now see TWRP recovery.
NOTE: ON SOME ANDROID 5.1.1 DEVICES IT IS NECESSARY TO GO TO:
Settings -> Developer Options -> OEM unlocking
AND ENABLE OEM UNLOCK FIRST OR YOU MAY ENCOUNTER 'BLOCKED BY FRP LOCK' WHEN FLASHING.
twrp_3.0.2-0_sm-a800i
PLEASE DO *NOT* DIRECT LINK TO THESE FILES. PLEASE LINK TO THIS POST
To Root:
Flash the SuperSU zip below with TWRP.
DO NOT LET TWRP ROOT YOUR DEVICE IF IT ASKS OR YOU WILL BOOT LOOP, ONLY USE THE FILE BELOW:

Yeah. That's what I did wrong. I turned the OEM Unlock off after a successful root. that was yesterday, but today after restarting my phone the frp lock triggered.
---------- Post added at 03:06 PM ---------- Previous post was at 03:01 PM ----------
I guess what i need to do is to download the firmware from sammobile. when i go there i only see China and HongKong as country choices. my country isnt there and my fone says its from Vietnam.

Hi @ashyx. i downloaded the firmware file that i need, while extracting it is giving me a WinRar error that the file is corrupted. I know the downloaded completed properly because i was checking the whole time.
Additionally i believe i do need the latest Samsung USB Drivers that will work for my phone. I can't find it here.
Any tips would be great. and again, thanks a lot for the help

Was the file in .rar/.zip format or did it end in .tar/.tar.md5?
Also, usb drivers can be found on samsungs official website for your country.
Most of the times, usb drivers do not need to be downloaded seperately if you are using an updated windows system.
Plug in your phone in download mode and start up odin. If the "com port" turns green, your phone is detected successfully.
Thanks for replying @abhinavparasher it was in zip file but when i extract it its in tar.md5. even when the error stating that the file is corrupted appears the whole extraction process still completes itself. and i already downloaded the USB driver and hope this works

Use 7zip to extract it not Winrar.
If it says corrupted again then the download is not complete.
USB driver: http://developer.samsung.com/technical-doc/view.do?v=T000000117
Also you say your phone is made in Vietnam.
Samsung manufacturer their devices in Vietnam and Korea so that doesn't mean that's the firmware you need.
If you are from the Philippines then download the firmware for the Philippines.
www.sammobile.com/firmwares/database/SM-A800I
There is an app called Samsung phone info that will tell you everything you need to know about your device.
@ashyx thanks! i pre downloaded the Stock Firmware from the Philippines. i chose Openline since it is indeed openline. That is also the file that says it is corrupted when i try to extract it. I am downloading 7zip right now. I'll update you as soon as i get somewhere with this.
I would lie to try the Samsung app you're talking about but right now the only thing happening to my phone is go to logo screen then turn off again.

To disable forced encryption and mount internal storage:
(Note this MUST be flashed after SuperSU if you intend to root)
1. Boot to Twrp
2. Format Data partition using FORMAT DATA button under Wipe options.
(Note: This will wipe the internal storage)
3. Check DATA is mountable.
4. Install SuperSU (if root is required)
5. Install boot image patch below.
6. Reboot
Boot image patch
http://www.mediafire.com/file/ln38z3q9c6iz3ny/patched-boot.tar
just putting my 2 cents in, this TWRP does not work with J530Y, it installs and boots to system after being installed but trying to reboot when you enter causes a boot loop incase any 1 comes across this and has the same model as me, my only complaint is the, debug? text in the terminal, but thats just a small gripe of mine
work in j530f duos 2GB RAM? no pro version?
twrp working fine.But when i rebooted i lost root.Super su not found installed .Should i reflash super su and boot image

Mine could not see it as well. Maybe you should convert .tar to .img? After some research i found out TWRP can't flash .tar.
Although, recovery works fine without patching boot.
i did the same but end up well.Its working !!.Mine was both OEM and FRP locked .i did clean install of stock rom and disabled oem lock and installed twrp and rooted aswell.

I think you have to do the inverse process. Flash twrp and after supersu
Oke I start from scratch again...
Flashed the stok ROM first.
Enable OEM and USB debugging
Flashed TWRP twrp_v3.1.1_SM-J530F with Odin3 v3.12.7 and disable Auto Reboot option.
Important: Reboot my phone holding Vol down, Home button, Power button AND when vibrate, Imminently pushed Vol up, Home button, Power button to go directly into TWRP.
Install Magisk-v14.0 (it fails, but just do it instead of installing SuperSU)
Boot my phone and restore al my apps from the play store include root checker. It has already root acces now
Install MagiskManager-v5.3.0.apk and dowload inside this app Magisk-v14.0.zip and choose Update (recommended)
With MagiskManager you are now able to disable root checking apps like SnapChat from root access. So my Snapchat is still working now
Hope this will help you.
If so than let me know with :good:

thanks, the first prerequisite is the stock boot.img,, i tried backing it up using miracle box but encountered the 'unstable port' problem, what other possible ways i could extract the boot.img from my phone ?
and btw, i remember asking a guy somewhere and he told me that magisk won't root my device, is that true considering it's a less-known manufacturer ?

I'd try the TWRP route instead. I found this thread after about 2 minutes of searching on XDA (search words "infinix note 4 x572"):
https://forum.xda-developers.com/android/general/infinix-one-support-root-twrp-firmware-t3695803
It's a really good idea to use the XDA search, because it often works quite good.
If you want to keep the stock recovery on your device, you can actually just boot the TWRP image instead of flashing it. In that case, the command used in that thread:
Code:
fastboot flash recovery recovery.img
should be changed to:
Code:
fastboot boot recovery recovery.img
If that doesn't work, you can actually make quite easily make a backup of your boot image in TWRP and then patch that file in the Manager, to see if that works better.
If things don't work out in TWRP, make sure to provide the recovery log.

I'd try the TWRP route instead. I found this thread after about 2 minutes of searching on XDA (search words "infinix note 4 x572"):
https://forum.xda-developers.com/android/general/infinix-one-support-root-twrp-firmware-t3695803
It's a really good idea to use the XDA search, because it often works quite good.
If you want to keep the stock recovery on your device, you can actually just boot the TWRP image instead of flashing it. In that case, the command used in that thread:
Code:
fastboot flash recovery recovery.img
should be changed to:
Code:
fastboot boot recovery recovery.img
If that doesn't work, you can actually make quite easily make a backup of your boot image in TWRP and then patch that file in the Manager, to see if that works better.
If things don't work out in TWRP, make sure to provide the recovery log.

thanks alot for the quick responses, i will try it and reply as fast as possible
okay, i downloaded the twrp recovery image for Note 4, flashed it using Fastboot method successfully,
the problem is when i try to boot into the twrp recovery mode, i tried holding the power menu+ vol.down buttons, it sends me into a black screen with "factory mode" upwards in yellow, no button is working.
i then tried
Code:
adb reboot recovery
the phone reboots and says "No command" under a red triangle.
i then tried to flash the twrp img using sp flash tools, and flashed it successfully but the same errors occur, i can't seem to be able to boot into recovery mode.
i looked up for a solution for the "no command" problem, here's one:
I faced the same problem with nexus 6p. It works when you root immediately after flashing the TWRP. Keep the superSU file in the storage. Get into bootloader. Flash TWRP via fastboot. Without restarting anything, just press volume up/down buttons while in the bootloader to select recovery. TWRP will open. Flash the SuperSU.zip. Then restart the system. Next time, if you open recovery, you won't get the "no command". If you don't flash SuperSU and you try to open recovery later, you will get the "No command".

what i understood is that i shouldn't reboot my device using "fastboot reboot" , he says i should get into recovery mode directly without restarting, idk how to do that since there are no option for it on the screen, i just have
Code:
=> FASTBOOT mode...
on the screen !

unfortunately i never used the sp flash tool before, so i tried flashing a stock rom but the device is now dead with "dram failed" error, i'll try fixing this first
It's tricky trying to help with a device you don't have...
Did you manage to boot to recovery? Usually you use the volume buttons to select the options and then the power button to confirm. You could also just use the fastboot boot option command I wrote earlier. It'll boot straight into TWRP.
There are a few threads for your device around, so if you need help specific to your device, that's the place to go...
everything is fine now,, fixed the device by flashing a rom named (X572-H5312CE-O-180203V55) then used magisk app to patch the included boot.img, flashed the patched boot.img using sp flash tool,, and everything is working fine now,,,
thanks alot
the twrp from the post you provided is for an older firmware, this is why i couldn't get into recovery after i flashed the provided twrp img,, there is no available twrp for the oreo version of the firmware, but i requested one from twrp builder project,, thanks alot, i've learnt alot in the last 24 hours

Update 25/12/2018
Beta build released.
Current status - (Tested working)
Treble supported
You flash this at your own risk. Please ensure you have the stock ROM to hand downloaded from SAMMOBILE in case of problems. This will trip the knox counter.
NOTE: ON ANDROID 5.1.1> DEVICES IT IS NECESSARY TO GO TO:
Settings -> Developer Options -> OEM unlocking
AND ENABLE OEM UNLOCK FIRST OR YOU MAY ENCOUNTER 'BLOCKED BY FRP LOCK' WHEN FLASHING.
*****INSTALL INSTRUCTIONS:*****
Flash with ODIN in the AP slot.
1. Put your device in DOWNLOAD mode.
(Hold POWER + VOL DOWN + VOL UP)
2. Load the file below into the AP slot, uncheck AUTO-REBOOT and hit start.
twrp_3.2.3-1_a750_251218
3. After flashing and ODIN reports PASS immediately force reboot to recovery. Do NOT let the device boot to the OS.
You should now see TWRP recovery.
4. Flash the RMM bypass zip
https://forum.xda-developers.com/attachment.php?attachmentid=4481843&d=1524258795
NOTE: FAILURE TO FOLLOW THE STEPS ABOVE IMPLICITLY WILL RESULT IN STOCK RECOVERY REPLACING TWRP AT FIRST BOOT.
5. Reboot to TWRP (Do not boot to the OS yet)
*****OREO ROOT INSTRUCTIONS:*****
NOTE: To mount data it is necessary to first *FORMAT* (not wipe) the /DATA partition using the FORMAT DATA button under the wipe options.
PLEASE NOTE THIS WILL DELETE EVERYTHING ON INTERNAL STORAGE AND FACTORY RESET THE DEVICE, SO BACK UP ANYTHING YOU WISH TO KEEP.
Continue with the instructions below to prevent the data partition becoming re-encrypted.
1. To root I suggest downloading and installing the latest Magisk as this is a currently supported project, SuperSu is no longer getting active development.
https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
2. Copy the Magisk zip to a Micro sd card then install with TWRP.
3. Enjoy your rooted device.
DEVICE TREE: soon
PLEASE DO *NOT* DIRECT LINK TO THESE FILES. PLEASE LINK TO THIS POST

Hey. Does it work well? I wanted to install myself. but it seems to me that this is not a complete instruction. Does OEM unlock need to be enabled?

No matter how complete an instruction is, if you don't bother reading it in the first place it's not going to make any difference.

Can you try this build, it's built with the kernel from the latest source available - A750FNXXU1ARIC.
Be aware OEM unlock must be enabled and you MUST boot to TWRP immediately after flashing with ODIN. Do not boot to the OS.
In TWRP immediately install Magisk.

Same bootloop at the Samsung screen
However i use heimdall not odin so I have to unpack the tar file and flash the recovery image. i also use it to flash the stock recovery and it works perfectly
Does using it make a difference?
Edit: my phone is A750FNXXU1ARK2
A750FXXU1ARK7 Was my build number

So just to be clear :
Immediately after flashing twrp you are forcing a boot to recovery directly from ODIN?

Hmm looks like I'll have to take another look at the twrp config or kernel build.
If I pack the kernel into a boot image would you be willing to test if it boots?

It should have flashed ok. What TWRP did you use?
You need to flash stock firmware to be able to get rid of the "only official binary" message, then try rooting again.

This case you have to reflash stock firmware and wait 7 days or more for kg state to become normal in download mode.
Then try flashing TWRP again.
There are threads for the kg state issue.
Read this thread.
