  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
    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
    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.
