I extracted the rom.zip from the HTC RUU installation and I want to flash it to my phone.

In case it matters, it is an HTC Desire HD, rooted with Cyanomod and ClockMod Recovery on it.

All I want is to flash the original stock firmware back to the phone. Because the phone has now a different firmware RUU will not recognise it.

What I need to do?

PS. I tried to rename the file to PB32IMG.zip and use the update from zip option but it doesn't work.

How does it not work? Please provide details.


The general procedure for installing a new ROM would be:

  1. Download ROM .zip file to SD card.

  2. Back up current ROM in case new ROM does not work:

    • Boot to Recovery Mode (hold down the Power and Volume Down (Vol -) keys at the same time under boot)
    • Select 'backup and restore'
    • Select 'Backup' and confirm
    • wait for process to finish and go back to Recovery main screen
  3. Wipe and factory reset (this is important for stability! Especially when installing a different ROM, and not just an update. With an update you can usually skip factory reset):

    • Select “wipe data/factory reset” and confirm
    • Select “advanced” then “wipe dalvik cache” and confirm
    • wait for process to finish and go back to Recovery main screen
  4. Install ROM.

    • Select “install ZIP from SD Card“
    • Select “choose zip from sdcard“
    • Select the .zip file you downloaded to the SD card in step 1.
    • Wait for process to finish, go back to Recovery main screen and select Reboot.

Where in the above process do you get stuck?
