sound like a flatten battery to me. still under warranty? send back to check la.

For those who want to upgrade here r the instruction:

Guide from xda-developer.

My experiment:

1. Boot into boot loader screen ( the screen with red, green blue colour ). ( soft reset and keep pressing the camera button )

2. Then connect it to pc (usb). Make sure the active sync is connected. ( i'm using XP Pro with Active Sync 4.5, heard from ppl that Vista will cause some problem, please also make sure ur pc never ran from stand by or hibernate.)

3. Run ROMUpdateUtility_NV_G3.exe ( for phone ipl and spl end with .0000) , or ROMUpdateUtility_NV_G4.exe ( for phone ipl and spl end with .00001). http://rapidshare.com/files/32728615/Proph...AViet_Step1.zip - password: PDAVIET

PLEASE MAKE SURE U SELECT THE RIGHT ROM UPDATE UTILITY OR U WILL BRICKS UR PHONE.

4. Just follow ur on screen, should be click next and next and next.

5. It takes less than 2 minits in my case and the phone hard reset by it self. Calibrate the screen tap.. tap... and u r on with ROM 2.20.7.34.

6. Then installed the Prophet_4.0.0.0.1_PV rom by running Upgrade_ROM.bat from the computer. http://rapidshare.com/files/32714434/WM6_P...et_v4.0.0.1.zip - password: PDAVIET

7. this time it take longer, just wait. dun touch anything.

8. When the CMD prompt finish it will ask you to hard reset your phone. ( camera button + voice command button and power button ).

You are done.

Hope you all enjoy
