This method may work but I haven't tried it yet. So be careful if you attempt it

1. Reboot into recovery

2. Connect to your PC and enter adb shell

3. Within the adb shell type:
Code:
cd /
cat /dev/mtd/mtd0 > /sdcard/misc.img
adb pull /sdcard/misc.img

This will dump your misc partition on your PC

4. Open misc.img in any hex editor and find your version string in the format x.xx.xxx.x and change it to 0.00.000.0

5. Push the modified misc.img back to the sd card and flash it back
Code:
adb push misc.img /sdcard
cd /sdcard
erase_image misc
flash_image misc misc.img

6. Relock the bootloader using fastboot oem lock and flash an RUU containing an older HBOOT version

What problem are you getting in getting into recovery..??
Is the power key and volume down button combination not working..??

no button combination not working and not entering recovery.:(

And you've tried to boot phone completely, plug usb in phone and pc and in Windows press start, then in the text field right above stay type:cmd and enter. You now are in command line. Now type arbeid devices, enter. The output will tell you if you are in adb mode. If yes, type adb reboot recovery and enter.

I don't have HTC, but this works for my LG o2x, LG 4x, xperia arc s and xperia mini pro. It should work on HTC if normal method are vol- and power pressed and held simultaneously.

Perhaps u have not configured and setup adb at all. Try googling it.
