+### OP7_Unbrick: How I Unbricked My OnePlus 7T Pro Using the MSM Unbrick Tool
 
+## Introduction
+
+In this blog entry, I will explain how I bricked my OnePlus 7T Pro and how I successfully unbricked it using the MSM Unbrick tool. This guide will also serve as a repository for the necessary tools and resources, specifically for the OnePlus 7T Pro.
+
+## The Situation
+
+To explain the situation briefly, it’s pretty straightforward. I love custom ROMs, and since I use a Google Pixel 7 Pro with Graphene OS as my main device, I don't worry too much if one of my other devices gets bricked or broken. I had [Elixir OS](https://projectelixiros.com/home) installed on my OnePlus 7T Pro but wasn't satisfied with its overall look and performance. I don't know if the performance issues were due to the software or the hardware, but I decided to switch back to [crDroid](https://crdroid.net/), which I love for its unique features.
+
+One of my favorite features of crDroid is the ability to swipe up slightly from the bottom to access a dock-like interface with up to five icons (which can also be folders). So, I tried to dirty flash crDroid over Elixir OS using Elixir’s recovery. Unfortunately, this didn’t go well.
+
+My device ended up in a state where it was practically unusable. It wouldn't boot into fastboot mode, and even when it did, I couldn't flash certain partitions, or some partitions seemed broken. I recalled having a similar issue about two years ago with the same phone, which was my daily driver back then. 
+
+Remembering that it was a relatively easy fix, I was frustrated when I couldn’t get the phone to boot again. Thankfully, I had some free time at work, and after some effort, I managed to revive my phone.
+
+## How to Fix It
+
+I don't claim to know everything about Android, ARM architecture, or phone internals, but this method worked for me, and I believe it could help others. This guide can also be used to reset your phone completely if something is off or not working. But don’t quote me on that!
+
+Here’s how my phone looked when it was bricked, and this fix was probably the only solution.
+
+### Things You Will Need
+
+- Your OnePlus 7T Pro (This tool is specific to this model. For other OnePlus devices, you can check [here](https://onepluscommunityserver.com/list/Unbrick_Tools/)).
+- A USB-C cable to connect to your laptop/PC.
+- A PC/Laptop running Windows (I apologize, but I couldn’t find a Linux equivalent tool for this task).
+- [Qualcomm Drivers](https://qcomdriver.com/)
+    - Just follow the installer instructions.
+- Download the MSM tool for your device (only OnePlus devices are supported as far as I know). For the OnePlus 7T Pro, you can find the tool here. For other devices, you can search [here](https://onepluscommunityserver.com/list/Unbrick_Tools/).

+
+### How to Actually Fix It
+
+1. **Unplug and Shut Down Your Phone Completely**
+   - Don’t let it run out of battery, as this can damage your OLED screen and complicate the process. 
+   - To shut it down, hold the `volume up` and `power` buttons simultaneously until the screen goes blank and the phone shuts down.
+
+2. **Open the MSM Tool and Click on "Start"**
+
+3. **Connect Your Phone in Qualcomm Mode**
+   - With the phone turned off and the USB cable plugged into the PC, hold the `volume up` and `volume down` keys, and plug the other end of the cable into the phone.
+   - **Caution:** There will be no sound, no screen turn-on, nothing! Only in the Device Manager will you see the Qualcomm device being recognized.
+
+4. **Wait for the MSM Tool to Detect Your Phone**
+   - If the MSM tool catches your phone, let it sit for a while (for me, it took about 300 seconds).
+
+5. **Enjoy Your Freshly Unbricked Phone!**
+
+And that's it! This method worked for me, and my OnePlus 7T Pro is now functioning perfectly again. Whether you're looking to recover a bricked device or reset your phone completely, the MSM Unbrick tool is a powerful and relatively easy-to-use solution.
