  • I got this message: the rom utility cannot update your phone. When I did step 4 the pyramid software did not recognize the phone connected to the pc.

      Make sure you have the correct cid for the update, check with app CID Getter.
      You might have to reset the phone several times, make sure it is in HTC Sync mode

    almost the entire process work except the last part(fail to reconigze signature)

    • Yeah I’ve tried updating all the drivers for htc and using an xp machine as the sync software was having issues on 7.

    • Was your device recognized by the ruu from the bootloader?

    • NARDS!

    • Sanitypreservation

      You have the wrong CID for the update. Check which you have, then change it to an appropriate one or SuperCID

  • Any help?

  • Sanitypreservation

    For people having problems, restart your phone into fastboot and do the pocedure again.
    If that won’t work you will have to extract the rom.zip from the .exe, rename it PG58IMG.zip, put it on the sdcard and flash it from hboot.

  • Sanitypreservation

    Running a RUU from Windows do NOT need HTC Sync !! Your phone should be in HTC Sync Mode but disregard any errors your phone is giving you. You might have to redo those settings more than once.


    • Right. Tried from the fourth pc and only installed the htc driver posted. It was recognized under manage/drivers but the RUU doesn’t recognize the phone in HBOOT. thx

      • Sanitypreservation

        Ruu isn’t supposed to be run when phone is in hboot.
        You run the RUU from PC, phone is running normally but in HTC Sync mode

  • Sanitypreservation

    Further to the Restore root. You will also need to reinstall BusyBox and your recovery of choice: ClockworkMod, 4Ext Recovery or whatever you prefer.

  • This is for Europe, for a US sensation you must change the CID in the rom for HBOOT

  • Rooted>clockworked> supercid worked off the pc. No bugs so for!Thanks for posting!!!

  • guest

    • Sanitypreservation

      Are you on AT&T ? Then the option to install from “unknown sources” has been disabled, send your appreciations to AT&T

  • lucksta

    it says i need correct rom update ?????

  • Chris Welton

    When you say ‘skip this step’ does that mean that I can run an RUU with no HTC sync, just in hboot and fastboot mode?
    (I’m getting desperate here, trying to upgrade Desire S using sync but disconnect occurs when sync looks for bootloader)
