    • The process is the same as Windows Vista / 7 with Windows Mobile Device Center. Do you able to sync contact, calendar when connect to Windows XP with ActiveSync?

  1. I just followed every instruction u gave, but after i accept to update the ROM, it loads for a minute and says “INVALID VENDER ID” and “This update utility cannot be used for your PDA phone. Please check your Update Utility”.

    Error [266]: Update Error
    “The Update Utility cannot get response from your PDA Phone. Please check that your USB cradle/Cable is connected properly between the PC and your PDA Phone. And also check your PDA Phone.”
    I completly checked the USB Connection. There is no problem with the usb connection.

    Shall be thankfull to you.

  6. Hey Jayce, my hd2 cant launch htc sense after i change the rom . Can you plz tell me y and how can i solve it? Thanks.

    • That’s depend on your Android ROM. HTC Sense build can sync with HTC Sync. Other builds will sync with Google account once you sign in.

  9. Im trying to go back to Win 6.5. I had Utimate droid on my HTC HD2. I held the volume button down while I powerd the phone. I was then able to go to the R-G-B-W screen:
    PB81120 SS-B3
    SPL-2.08.HSPL 8G XE
    0x05
    CotullaHSPL 0x40

    It reads Serial at bottom of screen. After connecting the usb it read USB and I then connected to PC and ran the ROMUU and it went through the update process….HTC logo came up and it updated using 3.14.531.1. It then finished and it froze on the white and pink screen “stick together”. I dont know what happened and what to do next? I want to go back to WIN6.5. How do I do it? Please help! It still reads SPL-2.08.HSPL. Do I need to remove the HSPL so I can reinstall WIN6.5?

  10. How do I remove HSPL3 ~ SPL-2.08.HSPL and go back to my original settings to reinstall WIN6.5? How do I check to see if I have HSPL3?

  11. How can I put the file leoimg.nbh on the sd card if cant access through Windows Mobile Device Center / ActiveSync. ActiveSync doesnt see the phone after its connected. Can I put the leoimg file manually on the sd card? How do you make sure its rooted to the sd card?

  12. I tried the sd card method. I held the volume low button and powered on…..I go the R-G-B-W screen. It says…..RUUNBH in top righ corner. I also get PB81120 SS-B3
    SPL-2.08.HSPL 8G XE
    0x05
    CotullaHSPL 0x40
    It also says UPgrade ROM code error. Please try again.

    It says Serial on the white bar at bottom. What can i do?

  13. Yeah! I dowload it from Tmobile website. Do you think if I install Windows 7 ROM then I can access ActiveSync on my computer and then reinstall Win6.5 by using the leoimg.nbh method? Ill try and let you know if it works. SHould I use MAGLDR 1.12 or 1.13? Ill try MAGLDR 1.13.
