Bypass Samsung Knox factory reset protection

[MatrixMario012]

I have an Android device supplied by my government for students and secured by Samsung Knox. However & unfortunately, I forgot the security pattern of the device and I want to hard reset it to access it again. But Knox prevents factory reset by all the ways :/

I have tried entering the pattern in a wrong way 20+ times but it still refuses to achieve a factory reset. I have also tried booting into Android recovery but the factory reset option says MDM disallows factory reset.

Also Google's Find My Device can't even detect the device so I can't reset it using Google's Find My Device. And developer options are disabled by Knox too so I can't do it using adb

I know that I have made it complex but its the truth and I was wondering if someone knows any way or PC tool to hard reset without USB debugging, or a PC tool that can enable USB debugging.

I don't want to flash ROMs because they will erase Knox which I shouldn't erase :/

Any help would be appreciated.

hard reset of a device with secure knox

I have exactly the same problem.

Can you share the solution if you found one?

Thanks.

See if you can enter recovery mode

See if you can enter recovery mode

I can enter "safe mode" but even there the tablet ask me for the password I haven't got in order to switch off the flight mode that prevents any attempt to locate the smartphone from the Samsung remote service.

Secured Knox prevents hard reset.
No password + flight mode on => Do I throw an almost new device to the bin?
There should be a way, I cannot imagine there is not way around this.

Anyone find a solution to this?

Update for posterity. I did find a way around this. You essentially have to re-flash your device - which isn't difficult, but it will result in losing all data on the device.

1. Enter download mode by holding vol+, vol- & power keys while plugging in your phone via USB to your computer (windows machines only). This must be done from a powered off status.
2. Download Odin
3. Download OEM firmware for your device (Samfirm or Firja tools can help with this)
4. Download Samsung USB drivers
5. With all of these tools and with your firmware obtained, go into download mode and flash your device.
6. Once complete, the device will format itself (you will lose all data) and boot into initial configuration mode where you can set up you device as if it were new.

Did you success flash fw ?
after finish flashing , any authentication required ?

Nope. Phone works as if it were new out of the box.

This procedure didn't work for me.
In order to factory reset, before flashing the stock firmware/ROM, I had to flash the TWRP and wipe everything.
Followed this procedure for my galaxy tab:

https://xdaforums.com/t/recovery-twrp-2-8-3-0-for-galaxy-tab-4-8-inch.2980716/

It worked fine. Once wiped through recovery TWRP, I flashed the stock ROM and everything was fine and factory reset.

Unfortunately before starting I tried an auto root procedure but Knox recognized and locked everything (so the counter now is 0x1).

You can get to Odin mode with knox. Message me back and I’ll explain. You basically trick the device. Does it have removable battery?
I’ve done it on dozens of Xcover pro devices.

אתה יכול להגיע למצב אודין עם נוקס. שלח לי הודעה ואני אסביר. אתה בעצם מרמה את המכשיר. האם יש לו סוללה נשלפת?
עשיתי את זה על עשרות מכשירי Xcover pro.
סיימון פשוט

Hey friend
You say you can get into Odin mode with active knox?
I tried dozens of options without success, I would be happy if you explain to me what your solution is (my device without a removable battery ...)

The first recommendation did not work for me, too. After the tab reboots, it says its installing the updates but up to 32% only, then it erases, then it goes back to the same problem.

Tried your quoted solution. However, upon installing twrp, it says it cant install because of frp lock. How do i go about it? Please help....

SM-G525F. yup, can flash android BUT knox persists.

seems TWRP file needed but none exists.

Tried the video above in post 5 but there is no CM file.


Any Ideas?

I have 2 X cover pro devices that are knox locked. Could you explain how you manage to trick the device and get to Odin mode?
