+# Setup Windbg KDNET
+
+## Preparation
+  - A device with windows installed as debugging slave.
+  - UEFI Image
+  - An windows device with [windbg preview](https://apps.microsoft.com/detail/9pgjgd53tn86) installed as debugging host.
+  - USB Cable
+
+## Setup BCD
+  - Mount ESP Partition on you phone with root permission in adb shell or termux.
+    + Simply jump this step if you are using USB mass storage mode.
+    ```bash
+    # Execute on phone
+    mkdir /dev/esp_mnt
+    mount /dev/block/by-name/esp /dev/esp_mnt
+    ```
+  - Copy BCD to your host computer.
+    + If you are using UMS, find the BCD file and copy it to D: or anywhere you want in explorer.
+    + Copy to /sdcard
+    ```bash
+    # Execute on phone
+    cp /dev/esp_mnt/EFI/Microsoft/Boot/BCD /sdcard
+    ```
+    + Pull to computer.
+    ```powershell
+    # Execute on computer, assuming installed adb.
+    # Assuming copy to D:, you can set any path you want.
+    adb pull /sdcard/BCD D:\
+    ```
+  - Open an **administrator** terminal and set bcd configurations.
+    ```powershell
+    cd D:\
+    bcdedit /store BCD /set "{default}" testsigning on
+    bcdedit /store BCD /set "{default}" nointegritychecks on
+    bcdedit /store BCD /set "{default}" debug on 
+    bcdedit /store BCD /dbgsettings net hostip:169.254.255.255 port:50000 key:1.1.1.1
+    ```
+  - Push BCD back to your phone.
+    + If you are using UMS, simply replace the original BCD file.
+    ```powershell
+    # Execute on computer
+    adb push BCD /sdcard
+    # Delete BCD after pushing
+    del D:\BCD
+    ```
+    ```bash
+    # Execute on phone
+    # Backup nomal BCD
+    cp /dev/esp_mnt/EFI/Microsoft/Boot/BCD /dev/esp_mnt/EFI/Microsoft/Boot/NMBCD
+    # Backup kdnet enabled BCD
+    cp /sdcard/BCD /dev/esp_mnt/EFI/Microsoft/Boot/DBGBCD
+    # Replace active BCD
+    cp /sdcard/BCD /dev/esp_mnt/EFI/Microsoft/Boot/BCD
+    ```
