Preparing Your HTC HD2 Hard SPL
The first thing to do is to get hold of the HSPL4 file and save it to your computer. Run the application, and note the warning. Next, switch off your HTC HD2.
Holding the volume-down button, press and hold the power button to switch on your handset, keeping the buttons pressed until you see a distinctive four colour striped screen, and then release the buttons.
Read the display, looking for one of the following:
- SPL 1.42.0000
- SPL 1.62.0000
- SPL 1.66.0000
- SPL 2.07.0000
- SPL 2.08.0000
- SPL 2.10.0000
- SPL 3.03.0000
If none of the above is listed, you probably have a custom Windows Mobile 6.x ROM installed, and will need to install the original ROM for your device.
On your PC, click next in the HSPL4 window, and connect your HTC HD2 phone to your PC via USB. When the phone is recognised, you will be given a drop-down menu to select which HSPL to choose. Select 2.08.HSPL and then click Next.
Keep your phone connected while this process completes. Confirm success afterwards by switching off your phone and repeating the volume and power button combination above to find the text SPL-2.08.HSPL and CotullaHSPL on the striped screen.
