Bootloop on Desire HD

Hi Peeps. Appreciate any help here.
Recently got 02 faulty Desire HD from someone. No idea what he did. One of it has a bootloop, while the other is just stuck on the HTC logo. I will just concentrate my problem on the device with the bootloop as it seems to have a higher chance of recovering.
Was able to boot to HBoot and shows me this screen. I will type it out as I have no access to camera for now.

Tried to flash stock rom, cannot. Go to recovery, goes back to bootloop. Factory Reset, goes back to bootloop. Is there anyone to revive this phone?

Can u flash stock roms that's in one file .exe (RUU i think)? Boot into Hboot, plug usb cable and run the rom installer

That's what I did. It could not complete the update.

This is the rom that I used...

You are s-on. You have to flash the boot.img using fastboot after installing the rom.

Have you fastboot flashed a recovery?

Firstly. is there anything to make it S-OFF? Couldn't find a method that works. Most of it I found requires to boot into Android which is impossible for my case.
Also tried to put PD98IMG.zip in SD card to flash it, but give CID incorrect error.

Knowing what the error was would be helpful. Of you want S-Off you need to relock and do it manually.

actually what really matters to me is that I can get it working to stock rom. Rooting can be done later... but I cant even get it flashed to stock rom!!

I will try my best to explain cause I have no idea what's happening...
1. used fastboot using CMD to flash CWM to recovery. Error: signature verify fail.
2. Tried RUU.exe to flash. Simply says the update could not be completed.
Is there any thing I could do with Hboot or Fastboot that could revive the phone? I think I tried almost all methods... unless there is other ways that I have not tried...

Are you unlocked? Exactly what command did you use to flash? Are you drivers properly installed (HTC Sync with phone unplugged)? Did you flash from the folder containing your recovery.img?

1. I'm on s-on. Does it matters?
2. Bootloader should be unlocked after flashing the unlock.bin from htcdev.com. I saw the *** UNLOCK *** when I go into HBOOT.
3. Command I used was *fastboot flash recovery recover.img*. The recover.img is actually the CWM recovery.
4. HTC Sync is installed.
4. Yes i did. It gave me FAILED status. Error: Signature verify error.
I will try to snapshot whatever process I did to make my explanation clearer later part of the day.

Make sure the file name is correct of the recovery.img file

Signature check is failing or the .img file is flaw (try downloading again) or your bootloader is not unlocked in its whole. That happens from time to time. Try using this recovery image (touch CWM):

[Q] [SOLVED!]HTC Desire z bootloop

So,
I just bought a Htc Desire z a few days ago. Unlocked the bootloader, Installed CWM. All was going well until I decided to flash a Rom then the phone when into a bootloop and CWM stopped working.
So far I've fixed the recovery through fastboot but I'm still in a bootloop.
Any Ideas?
Additional details:
I'm on Ubuntu, I'm not so good with fastboot(or adb), the phone is a Turkish HTC desire Z, I have a NAndroid back-up right before I flashed the rom. I've tried combining it with the stock recovery. Obviously didn't work.

Hi,
VISION PVT S-ON
It means security ON
So, it won't let you flash anything
First, you have to run a rom again (dunno how....
from bootloader what are yours options? You can go to recovery?
if not, maybe installing a RUU from bootloader... But wait, i'm not sure you can...
And then, you'll start again :

No actually I can extract a RUU to a IMG file.
I currently can go into the bootloader(therefore into fastboot) and I can flash recoveries long as they're in img format.
I know this going to sound stupid considering that I got this far but what exactley is a RUU ? I mean I know I got the Hboot update from one but do they contain stock Roms as well?

I strung a few together tutorials but you know they're all same. sudo fastboot oem get_identifier_token. So yes.

in that case you just have to copy the boot.IMG file from the rom you downloaden. Put it in the map with fastboot etc. Then open a terminal and type fastboot flash boot boot.img I dont know if how this works on Ubuntu. But i think its something like that on Ubuntu.

didn't see much on s-off. You do have anything else?

Its in the first post, first you need to get a factory image running and relock your bootloader, then follow the steps in the xda wiki or strawmetals PDF guide. If you don't want to do this and would rather keep secure flags on then then each ROM you flash you will need to fastboot flash the kernel when done
But I highly recommend to get true radio s-off

after that..then you can installing custom recovery download a TWRP recovery from here.. and copied that file to adb.exe or fastboot.exe folder place on your pc...then connect your phone to pc with FASTBOOT mode..then open cmd source to your adb or fastboot.exe folder..and type "fastboot devices" if success detect your phone..then continued typing "fastboot flash recovery openrecovery-twrp-2.6.3.0-ace.img" ...done..
now your hboot is already update..and already had recovery too..
just a note..don't forget to Nand backup your rom first before you installing any custom rom you want later..
hope this can help..

unable to fix as follows:
I formatted the sd card, as it had not seen the recovery, I used this tip XDA_h3n friend and installed the recovery by fastboot.
I downloaded the rom Android Revolution HD 9.2 and installed the recovery.
It worked perfectly!
But I want to install latest roms with sense 4 or 5.
Can you give me a safe procedure, please?

then after that you just need wipe everything accept sdcard..then you can installing the rom you want...

yes you don't need to unlock bootloader again...because your bootloader is already ENG S-OFF (Engineering bootloader)..then your bootloader is already open or automatic you can accessed more than just unlocked bootloader
that's why i suggest you to flashing a stock RUU that are already rooted and modified by Phiber2000 that the link is in my previous post above..
if you did it before..than your bootloader will replaced to the version :

Help, can't flash any KitKat ROMs! [How to update recovery]

This seems to keep coming up so for those of you who can't find the fix, please don't create new threads or post all over the developers forum
The most likely reason you can not flash 4.4.x and newer ROMs:
You have an old recovery
why would this matter?
Basically the way permissions are handled in the updater-script (what tells your device how to flash the ROM) have changed
and thus if you flash a newer ROM with an older recovery you will more than likely see a similar error to this:
set_metadata_recursive: some changes failed
Click to expand...
Click to collapse
Click to expand...
Click to collapse
So how do I change recoveries?
you need grab a flashable.zip of the new recovery and then flash it in current recovery
or
a better and safer way is to use fastboot to flash the new recovery
Code:
fastboot flash recovery recovery.img
*note, change 'recovery.img' accordingly if this is not how the image is named
Click to expand...
Click to collapse
Click to expand...
Click to collapse
two other quick notes:
*you can just fix the updater-script yourself to be able to flash a new ROM in an old recovery, but really this is time consuming and poitless
*another method to flash the recovery is to create a PC10IMG.zip and place on SDcard then boot to bootloader to flash, but more work than needed

Silly mistake led to softbrick..
Could you please help me with this problem?
I had CWM 6.0.4.5 flashed in order to install Flinny's CM11 Alpha 5, FC were very common so I was really excited for PureKat ROM
but then I didn't read the instructions carefully enough and switched the phone off instead of rebooting the system after leaving Aroma installer...
Now I'm stuck in a bootloop which constantly shows me the HTC splash, sometimes 2 seconds of CWM and then HTC logo again. I can get into Hboot menu but Factory Reset and Recovery lead back to bootloop, and my laptop (Windows 7 Professional) won't access the sdcard. Silly me also disabled USB debugging but that shouldn't be a problem because I did a full wipe before installing PureKat, right?
Anyways, I can't seem to establish any connection between PC and my DZ in Hboot, otherwise I would have tried to flash a new recovery just as you said
Any help is welcome, thanks in advance!

First thing to do would be to boot into bootloader and write down everything from that screen here, actually here

Is it safe to install ClockworkModRecovery 6.0.4.5 on HTC Desire Z (HTC Vision / G2)? On ClockworkMod site I found only 5.0.2.7 for HTC G2.

Yes it is safe, but not 100% perfect. The reason its not on the cwm site is that it isn't official and hasn't been submitted to become official, maybe some day.

For fastboot commend we need : eng hboot OR unlocked hboot from the htc website (limited commend, but enough for flash a recovery).
So , if some DZ user were too lazy like me , and didn't flash the eng Hboot, but did all the other steps from the wiki to get the root (including s-off), and won't to go through the wiki again, just use the demkantor PC10IMG file from post #30 here : http://forum.xda-developers.com/showthread.php?t=1728208&page=3
It work for me. Downside : current rom will bootloop. Can't do restore CWM from 4ext. only fresh install.

Good point @overdose
I do highly recommend an engineering hboot and radio s-off for many reasons, but yes simply unlocking your bootloader will allow you to flash a recovery, but most fastboot commands will still be unavailable

2.> Now restart your phone into fastboot mode...
3.> Plug your USB from PC to Mobile..(now it should say "FASTBOOT USB" in red text in Mobile)..
4.> Now open CMD...and type "fastboot oem rebootRUU"
5.> You should now be on the black screen with the HTC logo so now type "fastboot flash zip c:\PC10IMG.zip"...
(NOTE:If you get a message saying 'Failed, repeat immediately'.......just re-run "fastboot flash zip PC10IMG.zip")

Actually I planed to do so. I'm curious if your instructions applies to IMG files to (directly or with small modifications)?

Until you have an engineering bootloader most fastboot commands are unavailable. Grab the .zip from post 30 in that link and follow the directions there.
Alex was having a similar issue to yours earlier but he couldn't get the PC10IMG.zip to work on his SD card so he used the rebootRUU method, which could also work for you. I would advise to understand both methods as they can be helpful to learn down the road
To answer your question directly, you must use the .zip, .imgs will not work with either method

Until you have an engineering bootloader most fastboot commands are unavailable. Grab the .zip from post 30 in that link and follow the directions there.
Alex was having a similar issue to yours earlier but he couldn't get the PC10IMG.zip to work on his SD card so he used the rebootRUU method, which could also work for you. I would advise to understand both methods as they can be helpful to learn down the road
To answer your question directly, you must use the .zip, .imgs will not work with either method

I was sure method with sd card would work fine so tried rebootRUU and it worked. Below is method that worked for me. It is simply whole instruction for getting new recovery when starting without eng HBOOT. This is just 'compilation' of instructions from Alex Mitter and demkantor.
Download DZ_PC10IMG.zip from demkantor dropbox
Connect phone to PC (adb devices to be sure it is recognized properly)
Code:
adb reboot bootloader
to switch to HBOOT. I didn't need to switch to fastboot as it was already in fastboot mode. You might want to use fastboot devices to be sure it is recognized properly again
Code:
fastboot oem rebootRUU
Code:
fastboot flash zip DZ_PC10IMG.zip
to flash eng HBOOT
Code:
fastboot reboot-boootloader
to get back to HBOOT and validate it.
Download CWM recovery from 1st post in thread
Code:
fastboot flash recovery CWMrecovery.img
to flash freshly downloaded recovery
switch to recovery from HBOOT to verify version and proceed with PureKat instalation from there

Upgrading Hboot help

Hello everyone, need some help upgrading hboot to try out some roms. Currently I'm on 0.85.2425 and when trying to flash from here (http://forum.xda-developers.com/showpost.php?p=38947050&postcount=10) and here (http://forum.xda-developers.com/showthread.php?t=2445593) I get a 'writing zip FAILED'. If I flash the rom.zip manually from adb in oem-78 mode [fastboot flash zip rom.zip] everything goes smoothly but hboot doesn't update.
This is what I'm looking at.

I'm pretty sure it is. I've always been able to issue commands without issues and flashing roms, updating radio etc.

Here's what i get, I tried to get the output to go to a txt file but that didn't work.

The problem you can't flash in RUU mode could be the drivers or the fastboot app you are using.It could also be a CID problem.
You can check here how to upgrade your hboot by using fastboot.
But as long as you are S-OFFed you can flash a PD98IMG.zip from your bootloader by putting it in the root of your sdcard.(Just rename the rom.zip to PD98IMG.zip)

I don't know what a RUU mode is nor am I using any fastboot apps. I will look into this CID stuff.
I actually cannot do the PD98IMG.zip thing as my volume buttons left their home... and the visible metal contacts don't do anything if shorted.
Thanks for the link, I will check out!
EDIT: The post you linked me to has the same instructions as what I've been trying, I mean exactly the same stuff. This is the 3rd hboot rom.zip I've tried and it worked! I'm on 2.00.29 so thanks a bunch for that link
EDIT 2: Now unlocking the bootloader from HTCDev, got to last part and need to use volume buttons! Doh! I'm stuck now and the phone will not boot into the ROM.
EDIT 3: Got it! I didn't realize that there was a tiny button under the actual volume key, just had to press it with something small.
