How To Boot into Bootloader Mode on HD2

1. Remove the battery cover on th back of your HD2.

2. With the battery still in place, hold the volume down button.

3. While holding down the volume down button, press the reset button using a pen or a pencil (it is red in the image above but it is yellow on my HD2) on the bottom left. Don't worry it won't reset your HD2.

4. The phone will boot into Bootloader Mode and the screen should display a "tri-color" screen. When you see this, go ahead and let go of the volume down button.

5. To get out of this screen, pull the battery out of the HD2 and reinsert it to have it reboot normally.

How to know if HD2 is 1024MB.

According to my knowledge, there are 2 types of HD2s.

• European HD2 w/512MB of memory.
• US T-Mobile HD2 w/1024MB.

For all the guides here at ZAP4 dealing with the HD2, you must have the US T-Mobile 1024MB version of the HD2.


TO CHECK WHICH HD2 YOU HAVE

According to this post at XDA, if you have a green call button and a red end button (like in the picture above) then you have the US T-Mobile 1024MB HD2. The European 512MB HD2, supposedly, has all white buttons.
