Hey there! Running into a wall with a **Samsung A15 SM-A155F U6 KG Lock Bypass**? You’re not alone. This lock, also known as Knox Guard, can be a major headache, especially on newer Bit/U6 devices. It’s designed to be tough.

But guess what? I’ve got great news. The **TSM Tool PRO** has a powerful and simple solution to handle this exact problem, and I’m here to walk you through it, DM-style!

What is KG Lock (Knox Guard)?

So, what’s this lock anyway? KG Lock (Knox Guard) is Samsung’s high-level security feature. It’s a step above standard FRP (Factory Reset Protection).

It’s often used by companies for **MDM (Mobile Device Management)** or by carriers/finance companies to lock devices. If you buy a phone on a payment plan, this lock prevents you from just factory resetting it and using it with another carrier or selling it. It’s a digital chain that ties the device to an owner or contract.

Why Bypass the KG/MDM Lock?

While it’s a strong security feature, it can lock out legitimate users. Here’s why you’d need to bypass it:

• You bought a second-hand device, and it’s still tied to the previous owner’s company or contract.
• You left a company and they forgot to remove the MDM profile from your device.
• The device is from a finance plan that’s been paid off, but the lock wasn’t removed.
• You’re a mobile technician, and this is a common service your customers need.

How To Bypass KG Lock With TSM Tool Pro (Simple Explanation)

This is where the magic happens! TSM Tool PRO simplifies a very complex process. For the **Samsung A15 SM-A155F**, it uses a special **”QR-CODE + ADB”** method.

Here’s the simple version:

Instead of trying to “break” the lock, the tool uses a clever workaround. It activates ADB (Android Debug Bridge) on the phone’s setup screen, often by having you scan a special QR code. Once ADB is enabled, TSM Tool PRO sends a series of commands that essentially “provision” the device. It changes the **KG Status from “Locked” to “Active”**, tricking the phone into thinking it’s fully authorized and set up. No complicated flashing or apps needed!

TSM Tool Pro Support: 1-Click Method!

Yes, you read that right! For this specific model and method, TSM Tool Pro has streamlined the process into a near **one-click solution**. Once your phone is in the correct mode (with ADB enabled via the QR code), you just select the function in the tool, click the button, and let it work. It automates all the complex commands, saving you time and removing the risk of manual errors.
