The Knox bit is a one-way street. Once it's tripped, there's no going back. Here are the most common actions that will flip the Knox Warranty Bit from 0x0 to 0x1:
At the heart of Knox is a physical (electronic fuse). Unlike a software flag that can be rewritten, an eFuse is a one-time programmable (OTP) memory cell inside the processor or a dedicated security chip.
Many developers optimize custom ROMs (like LineageOS or modified stock ROMs) to bypass specific Samsung app checks. For instance, patched versions of Samsung Health are frequently available on forums like XDA Developers to restore functionality on rooted devices. 3. Triangle Away (Legacy Devices Only)
The Knox bit is triggered by specific actions that bypass Samsung's official bootloader restrictions. The counter will instantly change to 0x1 if you attempt any of the following: Unlocking the device bootloader. Rooting the device (e.g., via Magisk). Installing a custom recovery (e.g., TWRP). Flashing custom Kernels or unofficial ROMs via Odin.
Once tripped, several security-dependent Samsung apps will stop working permanently, including: Samsung Wallet / Pay Secure Folder Samsung Pass Samsung Health (in some older models or specific configurations) Warranty Status: reset knox warranty void 0x1 back to 0x0

The short answer is that This status is triggered by a physical hardware component called an e-fuse . Once this fuse is "blown" by an overvoltage during unauthorized modifications—such as rooting or flashing custom recovery—it is permanently altered and cannot be rewritten or "unburned".

You might find old tutorials discussing "Triangle Away" or various engineering bootloaders ( .tar files) that claim to reset the counter.
If you have already tripped your Knox bit to 0x1 , you cannot change the number, but you can bypass or mitigate some of the software restrictions caused by it. 1. Using Magisk and Play Integrity Fix
The only way to restore a device to a 0x0 state is to physically replace the entire motherboard with a new one that has an intact eFuse. Because this requires expensive hardware replacement, it is rarely financially viable for the sole purpose of resetting Knox. What Happens When Knox Trips to 0x1?
