HTC desire HD can not boot anymore after try to install android 4

[plopjj]

Hello guys,

I wanted to install a new version of Android (4.X), and I tried different steps
- first I wanted to downgrade my firmware version, but I saw that a goldcard was needed and the link to generate them was dead, so I skipped this part...
- So I unlocked the BOOTLOADER, then I installed ClockworkMod.
- Then I performed a fullwipe and tried to install different via the Recovery mode ROMS I downloaded. The issue was that all the installation were pretty fast (less than 1 minutes ) and none of them allowed me to start my HTC.

I am now in trouble since I can not start anymore my phone, cause I can not installed any ROM... Plus, I think I never put my phone as root, but I am not sure I can do this anymore (since the only thing I can do is start via the BOOTLOADER).

Could someone help me with my issue?

Thanks in advance....

Fastboot flash the boot.img from the ROM zip.

Thanks for your reply, but I think it s not enough.
See, when I launch power + volu,me down, here are the information display :
**UNLOCKED**
ACE PVT SHIP S-ON RL
HBOOT-0.85.0024
MICROP-0438
RADIO-26.03.02.26_M
eMMC-boot
...

Thing is; I think my phone was never rooted correclty, plus, I did not downgrade the firmware....

Any idea what I could do?

Er, nothing you've said implies that flashing the boot.img isn't your solution. You don't need root to flash the boot.img, just unlock, and you have that. You only need to downgrade to get S-Off, which you don't need.

What you could do is flash the boot.img from fastboot like I said, and see if it boots. If you're flashing a custom ROM (which you must be if you're flashing 4.x, since that's not officially supported), it will come with root.

Thx bananagranola: I tried to perform this action with 3 ROMs and they all failed...
Here are the steps I performed each time :
Download the ROM
Extract the boot.img from the ROM, and then do a connect my mobile with fastboot to my pc
Execute : fastboot flash boot boot.img
Go in Recovery, performed a full wipe and then installed the ROM (install from ZIP).
Problem is, everytime the installation failed at the beginning or the middle (with the VIPER one, around 60 %)...
Do you have any idea what I could have done wrong?

You really should do full wipe first, then flash your ROM of choice, then flash the boot.IMG from the rom last via fastboot last, this is probably why it keeps failing.

Yes, wipe, then flash ROM from recovery first, then flash boot.img from fastboot. With your current method, you're wiping the boot.img before flashing the ROM.

Thanks for the backup and confirmation of the advice I gave :thumbup:

Thx both, but unfortunately it does not work.
I performed a full wipe, then flash the ROM ( install the zip, which is often really fast, less than 45 seconds, except for the VIPER which failed in the middle). Then I do :
Extract the boot.img from the ROM, and then do a connect my mobile with fastboot to my pc
Execute : fastboot flash boot boot.img

Now I passed the HTC logo, but then blocked on a black screen....

Any Idea?
