How to upgrade HTC P3600(a.k.a. Trinity) to Windows Mobile 6 and unlocking the GPS

FOLLOW THE STEPS BELLOW ON YOUR OWN RISK.!
IT IS IMPORTANT TO NOTE THAT THIS PROCEDURE MAY TURN YOUR DEVICE TO A USELESS BRICK!
NO WARRANTIES AT ALL!

I use HTC P3600 as a phone/PDA which is armed with Windows Mobile 5.0. The device has a camera, 3G,WiFi,Bluetooth and more. It does not have a GPS(officially).
I noticed recently that the guys from xda-developers.com have published Windows Mobile 6 image for Trinity. It is important to note that HTC does not provide official upgrade for P3600.

So, I read some posts on the xda forums and finally managed to upgrade my device. I have now WM 6 on my P3600 and the most interesting part is that I have a GPS support.

I followed these steps:

1. Downloaded the WM6 image and ROMUpgrade utility on the PC:

2. Downloaded the following tool(SSPL-TRIN.exe) on the PC.
It allows to bypass the CID and signature check.

3. Connected the device to PC
4. Copied SSPL-TRIN.exe on the device
5. Launched SSPL-TRIN.exe from the device.
The screen turned-off anf a strange colorful screen appeared(bootloader mode)

6. Launched the ROMUpdateUtility.exe from the PC
I performed the upgrade on Vista so I needed to download the ROMUpdateUtility for Vista:

I just needed to replace the extracted files from Step 1

7. Followed the steps provided by the ROMUpdateUtility

And ops! I have the WM6 on my device! The big surprise is that the device has now a GPS support!

IMPORTANT NOTES:

• it is a risky operation and you may render your device unusable. Do it on your own risk
• do not launch any application on your PC during the upgrade process
• do not disconnect/turnoff the device
• do not restart/turn off PC
• make sure you have device battery charged over 50%
• disable PC hibernate/sleep features - or just move the mouse to prevent it
• carefully read the redme.doc before starting the upgrade process
