my way:
after downgrade if half brick and phone very late power on and show htc logo with vibree after 12 min phone go to normal mode and fastboot working but hboot stay frozen you can fix and repair your hboot with my eng-hboot if full bricked and hang on htc logo for ever or daed you need jtag metod for repair boot
1.rooted rom(custom rom) if have installed cwm you can install custom rom zip
2.root your official rom
froyo os very easy metod for root install z4root
and run it for root after prem root reboot phone your phone rooted(wait for 12 min) ok
for update and working old su you need download Superuser
install and flow this steep in preferences

ok now download my eng-hboot
copy to root sd card and connecting usb and select charging mode(usb debuggingn enable)
and falow finall steep in adb command:
type

adb shell
su
busybox md5sum /sdcard/hboot-eng.img
dd if=/sdcard/hboot-eng.img of=/dev/block/mmcblk0p18

plz check md5sum ........

ok now your hboot phone repair and phone back to normal working after repair boot copy finall official zip rom to your sd card (PD98IMG.zip) reboot phone to hboot mod and flash it
enjoy

Hi,

I have HTC Desire HD(AT&T).

I flash it with S-off and not sure that either it is rooted or not. Its cid was 11111111

I use following RUU and we can say that I downgrade it.

RUU_Ace_HTC_WWE_1.32.405.3_Radio_12.28b.60.140e_26 .03.02.15_M3_release_155032_signed.



After successfully flash phone not power on. I try to power on phone bu not success and no hboot menu as well. I pull off battery and insert it back.

Phone power on automatically after 4-5 minutes. But after power off phone buttons not works e.g Power button+volume down and up.

Please someone guide me and help. plsssssssssssssss

sorry for poor English.

Thanks and regards,
