enrolled knox guard prevent flashing factory binary (vbmeta) - Samsung Galaxy Tab A series Questions & Answers

When I try to flash a magisk modified image on the T500 I get the error 'enrolled knox guard prevent flashing factory binary (vbmeta)'
How can I get past this and flash the modified image?

its locked with Knox you need first erase it by enrolled Knox from Device Admin

I have done a factory reset from the recovery menu before, but then as soon as I try to flash the magisk modified image it gives that error.

You can't. Knox Guard is a third party security lock. It can only be unlocked by the co. that purchased the firmware to protect their property. Sometime it is a co. that furnished the tablet to an employee or it may be a finance co. that sold the tablet on a payment plan and won't unlock it till all of the payments have been make. But until it is unlocked by them, you cant' root or install custom ROMs.

The tablet was bought new from Samsung. I had originally rooted it using the current (BUJ1) firmware dl'd via frija using Magisk - but something went wrong with the rooting resulting in that error upon a reboot. Then that error appears everytime I try to flash a new magisk-altered rom.
Why would there be a third party lock given it was bought outright as a private sale direct from samsung?

I'm just going by what i read when I googled "Knox Guard". Have you tried starting from scratch by flashing BUJ1 via Odin?

Yeah, flashing stock fw works, but as soon as anything non-stock is flashed (including trying to flash just an empty vbmeta) it gets blocked with that error.

Samsung Newer Galaxy Phones CROM service relock, restart FRP and reget KNOX warranty

Hi all xda-developers members,
My father has a GALAXY J5 (2016) WHICH IS SM-J5108, variant for Hong Kong and China. All of you guys and gals know that newer Samsung smartphones has three things called:
CROM SERVICES, which is allow you or not to install custom ROM
FRP LOCK, which is Factory Reset Protection. After doing a FR, the stupid thing asks you a Google account
KNOX WARRANTY
Recently, I am attempting to use TWRP custom recovery temporarily to install Google Apps provided by Open Google Apps and the recovery, TWRP, I mentioned is basic requirements. When I finished all procedure, I've encountered some problems. First the CROM services is cannot be regain back the locking status. Next FRP Lock possibly cannot be turned on again. Last KNOX Warranty who is general warranty which is voided and now I want to gain back for it.
For now, I want to restore these of defaults. YOU guys and gals what should I do for now??

Download your firmware and flash
You have to download firmware of your phone and flash it via Odin with download mode in your phone
We are in the same problem, have you had a solution ?, because the roms I have found are without googles services

Flash TGY Rom, this have GAPPS, bug: internal speaker don't work, with headphones work

Android Pay not working.

I Haven't rooted my phone yet but it keeps telling me this when I open android pay, when I first got my phone I set my up my card but now it saying that phone is either rooted or bootloader unlocked which isn't the case.
On Vodafone UK, before this I used my OP3 with Magisk with Android Pay but I haven't used that since I've got my s8 so I'm not sure what the issue could be.
Any insight to this?
Besides the usual factory reset.
same here EE UK S8 not rooted (yet) but comes up with same error message. It worked fine on my rooted and hidden with magisk S6
edit - oh and factory reset doesn't work as I already tried that. I thought it might have had something to do with bringing over magisk app from my google backup but I specifically didnt install that the 2nd time around. Knox hasn't been tripped so its not that
I'm having the same issue on a Galaxy S8 via Tmobile. I've never rooted it, have no clue if the bootloader is unlocked and I'm stock since I reset the phone the first time I got the error. Still getting the error and Android pay help chat was not useful.
Same issue here, on Voda UK. I used Package Disabler pro and thinking I might have disabled something I need.
So since I had OEM unlock enabled after disabling it, it passes and safetynet now.
I had no problems adding cards, but a few days later when I wanted to add more cards, I get the error. I can't remember what I did in between that would've caused this, but definitely not rooting! I turned developer option to off and still get the error.
My S7 is rooted and TWRPed and have no problems adding cards!!!!???
Very weird. Working just fine on my rooted s8+ with magisk.
I'm on T-Mobile with a S8 and Android Pay connected to my PayPal is getting card read error everywhere I try to use it.
Safety net says everything is ok too. Not sure what's going on. I have the newest update and not rooted.

I installed different Samsung Pay Framework apk and now I want to revert back and downgrade to another version to make Spay work.. when I click uninstall updates it wont let me. (Gives message that App is needed by system administrator.. when I open sys admin nothing there. hidden app)
Any ideas or suggestions on how to downgrade Samsung Pay Framework?
Thank you in advance,
Joe

Hi Can you let me know how you managed to root with Magisk and get Android pay etc to work?
My phone:
Model: SM-G955F
SW: G955FXXU1AQF7
I tried rooted and couldn't get it working, and now recovered to official ROM and still can't get it to work?!?
Dont you people know anythin?
All EU(exynos) S8 and other galaxies come with unlocked bootloaders. Thats causing the problem
Lock it
Hi all,
I already posted a question in the Official stock upgrade but it got lost in the other comments, so I'm trying my luck again.
I had an italian branded SM-G950F (OMN), I wanted to remove all the Vodafone stuff, so I installed a MULTI-CSC as per the official stock firmware upgrade thread, when I did it I had my Australian sim card in and I got a weird UK CSC (the multi CSC didn't have australia in it), after installing everything I noticed that Android Pay didn't work, so I did a factory reset with my italian sim card in and still Android Pay was complaining that my firmware was modified or rooted.
I decided to use an australian specific firmware so I downloaded an XSA firmware and did the procedure again.
At this stage Secure Folder and Samsung Pay work (the phone is NOT rooted, this update has been the only "mod" I have done) but Android Pay is still saying that my rom may be modified or rooted so it doesn't open.
It is pretty important for me because my back supports android pay but not samsung pay
The phone is not rooted, if I reboot the phone in download mode the warranty void bit is 0 (which is good).
If I use Root Checker Pro, under safety net tab, I get CTS profile match as FAIL, I was thinking this could cause Android Pay to fail.
any idea?
start to uninstall suspicious apps, then restart . worked with my un-rooted S8. OEM unlock: OFF

Hi mariuscrist,
I'm not sure what app can be suspicious, I have reinstalled the apps I had before the firmware update and I could use android pay then. I'll see what it can be, probably it could be worth to do a factory reset and test android pay before anything else?

[A3 2016] Recover data from FRP Lock bootloop?

No idea what possessed me to do it (it was late), I unchecked "OEM Unlock", and bricked my phone.
(Android 5.1.1, stock recovery, rooted)
It's stuck in a bootloop with the red message "Custom binary blocked by FRP lock."
I've read many other posts stating that flashing stock firmware will unbrick the phone. That's great, the hardware can be saved. But I need the data; contacts, txts, photos.
What are my options?
Is there any way around FRP lock? I understand tit's intended as a security feature, and basically only happens when people do idiot stuff like unchecking OEM Unlock. So I doubt many devs/hackers have put much focus on developing workarounds.
Theoretically, Samsung may have the capacity to unlock the FRP lock. Is this a thing? Does anyone know anything about sending it to a Samsung tech center? Probably they would have difficulty guaranteeing the phone sender should have rightful access to the phone, so perhaps they provide no pathway?
@ashyx, I've read your posts, you're frankly a wizard. Any thoughts? Thanks
Frustrated with myself,

Really? Many posts I've seen have noted that "all user data will be deleted".
Do I just use ODIN, and flash AP? No app, or user data will be erased, or formatted like that?
A few mention "Initializing with Smart Switch"; I haven't done that before. Is that different than flashing firmware?

Searching for that question directly, it seems like flashing a ROM (e.g. stock firmware) will not directly erase user data; downloads, photos in DCIM, etc.
But, sounds like any user-installed apps will be erased (so any internally stored data would be lost).
And, data stored in system apps would be lost, too; e.g. tabs that were open in Chrome.
There's no way around the FRP lock, eh?
Here is Samsung's statement about FRP (Factory Reset Protection)
It describes the Google account "protection" features, but doesn't really describe how FRP lock leads to bootloops.
https://www.samsung.com/us/support/frp/
Factory Reset Protection (FRP) Feature
What is Device Protection, or Factory Reset Protection (FRP)?
Android™ devices provide built-in security features you can use to protect your device and information, including screen locks and data encryption. Data protection, or Factory Reset Protection (FRP), is a security feature on Android devices with Lollipop 5.1 and higher.
FRP is automatically activated when you set up a Google™ Account on your device. Once FRP is activated, it prevents use of a device after a factory data reset, until you log in using a Google username and password previously set up on the device.
How does FRP work?
When you perform a Factory Data Reset, all settings are returned to the factory default settings. All data is erased, including files and downloaded apps.
If you have a Google Account set up on the device, FRP is active. This means that after the reset, you'll be required to log in to the Google Account using the username and password. If you have multiple Google Accounts set up on the device, you can log in using any of the accounts.
If an unauthorized person tries to reset the device by another method, the device would still require log-in using the Google username and password. This means that if your device is lost or stolen, another person would not be able to reset it and use it.
What do I need to know about FRP?
If you want to reset your device to factory defaults, make sure you know your Google Account and password, because you'll need to log in at the end of the reset.
If you want to reset your device to factory defaults, but don't remember your Google username and/or password, you can do one of these:
Check your device’s Account settings for your account name, and reset your password via the device or at www.google.com.
It can take 24 hours for the password reset to sync with all devices registered to the account.
Remove the account before you reset the device.
If you already reset your device, but don't remember your Google username and/or password, the device can't be used. In that case, you can do one of these:
If you know your Google username but can't remember the password, you can reset your password on the device, or at www.google.com. It can take up to 24 hours for a new password to sync with all registered devices. After 24 hours, you can try logging in to your phone with the new password.
If you have multiple Google Accounts, and you can't remember which Google Account you set up on your device, visit https://www.google.com/android/devicemanager.
Log in with your Google username and password and check the list of devices registered to the account. If you don't see the device listed on the account, it means the device is registered to a different account. Use the same process to check for devices linked to your other Google Accounts. When you find the registered account, use it to log in to your device.
If you can't remember any of your Google Account information, you can send your device, along with proof of purchase, to an authorized Samsung Service Center. Samsung has special tools to reset the phone to factory defaults with no protection enabled.

Looking for a Samsung Authorized Support Center, apparently there are ZERO listed around Omaha, NE.
http://support-us.samsung.com/cyber/locator/asc_locator.jsp
There must be ASC's somewhere; I'm hesitant to mail the phone away because I think the tech will just wipe it. The whole point is to maintain the data :-/
What do I need to flash to remove "Custom binary" ?
Will flashing the bootloader back to stock unlock the FRP lock?
That's BL throuh ODIN, right?
Do I have to flash AP ?
Won't that remove all user apps and their data, and any user data associated with system apps?

Not being funny, but you're panicking over nothing. I can pretty much guarantee you will NOT lose any data, apps or settings. The DATA partion is untouched by stock firmware.
Just flash the whole stock firmware(not repair firmware) and you'll be fine.
If you're super paranoid about losing data then just flash the AP part.

I'm just trying to understand what's happening, know what I'm doing.
Because I was clearly stupid enough to uncheck OEM Unlock. (WTF was I thinking?!)

It will be exactly as it was before. Nothing will change.
There are only 2 binaries that need flashing, boot and recovery, however unless you are flashing the exact firmware you had previously you may get compatibility issues, so it's best to just flash the whole firmware.

Thanks for the more specific information.
I've never found any discussions about how to solve the frp lock bootloop, with the intention of preserving user data.
If you will indulge me a bit more, I'd like to learn, test, and then share this for others.
Do you know exactly Custom binary blocked by FRP lock ""security" works?
Where is the flag that gets tripped?
In order to solve this bootloop, technically just Boot loader and Recovery need to be flashed (the exact versions must be used, or comparability issues can occur).
Bootloader should be simple enough: BL is one of the specific upload choices in Odin.
Recovery is a .bin that's contained with the AP.tar, correct?
Is it possible to specifically flash only the Recovery?
(I am reading other posts and pages as I write this, sorry if some of these points and questions seem "obvious"; I'm still learning. Aren't we all )
This thread is particularly detailed re: ODIN flashing, although it is from 2013, and for a specific device

No, I didn't mention the bootloader, that is a different part of the firmware. The boot and recovery images have a .img extension and should be flashed under AP.
It is the bootloader that detects non official firmware and trips the FRP flag. If it's disabled in settings via OEM UNLOCK the bootloader ignores it and allows the device to boot.

Sh!t, sorry, boot.ing /= bootloader. Rookie mistake. #StillLearning
OK, so boot.img and recovery.img should both be contained within the AP component of stock firmware.
I can just flash those two, can't I?

Is there any non-GUI way to toggle the OEM UNLOCK?
Bootloader? Download mode? Recovery? Fastboot? ADB?
I assume not, since that might be a "security" risk. And also, if there were, problems like this would have solutions posted mentioning how to do that.
Sh!!!!!!!t... I was thinking I would have screenshots of the exact build that's loaded on my phone. That way I can find the right stock firmware.
Seems those screenshots are still in the phone, didn't get moved to external memory
All I know for sure is it's Andorid 5.1.1, but that probably isn't specific enough to get the exact right boot and recovery images.
I intend to flash the boot.img and recovery.img to my phone. Hopefully, this will avoid any data loss, while clearing the FRP lock bootloop.
I got the stock firmware for Android 5.1.1 for my Galaxy A3 (2016) (SM-A310M) here:
https://www.sammobile.com/firmwares/galaxy-a3-/SM-A310M/TTT/download/A310MUBU2APE2/73991/
This set of instructions says to extract the .img file(s) to flash, then just .tar them up using 7zip, and flash it as AP in ODIN.
http://howto.highonandroid.com/sams...extract-stock-recovery-from-samsung-firmware/
But... this one says to use Unified Android Toolkit, option ‘8’ (Create an Odin flashable tar), and then flash with ODIN.
https://skipsoft.net/flashing-a-single-partition-i-e-system/
Fortunately, I have a Galaxy A3 (2017) (SM-A320Y), which I was just about to upgrade to for my daily driver. It's blank, running Android 7.0, so it means I can test this process, see if data is preserved, with almost no risk to actual data. Got that firmware here:
https://www.sammobile.com/firmwares/SM-A320Y/COO/download/A320YDXU1BQH2/189605/
Ironically... I don't yet have a great method to intentionally trip the FRP lock bootloop
I think rooting and then unchecking OEM Unlock should do it (that's what wrecked my A310M)

If they're both stock based firmware then you can just flash the stock S7 firmware. Data should remain untouched.

Security Query in case of theft

I want to know that if my Mi A1 is unrooted with no recovery installed, bootloader unlocked and start up pin applied What are the chances that someone(thief) can reinstall rom on it and use it again. I am curious as to whether Android can be as theft proof as apple.?
Extract user data - no, reflash rom and start using the phone - yes (FRP bypass or EDL flash).

Regarding EDL Flash I read this recent article (https://www.xda-developers.com/xiaomi-anti-rollback-protection-brick-phone/) and it mentions that only authorized service centres has EDL access. Read and share your opinion.
I think FRP bypass may be difficult if the security patch level is latest .
A query although I had reset my A1 several times by going in settings but didn't received the FRP message on Restart. Is it normal

EDL mode has been locked for MIUI devices, but Android One can be flashed at home without major issues.
FRP protection is triggered when you perform factory reset from recovery. If you do it from settings, it is assumed that you are the owner of the device. With the existing implementation of FRP, I would not rely on its safety.
It seems that you are not worried about your data safety, so wondering why does it bother you if a thief can use the phone or not..? You have to buy a new one anyway..

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.

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.

But I couldn't find one.
Here's my post, it may help.

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.

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

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
