HTC Desire Z feared bricked. (Perhaps stuck in bootloader)

I appoligise if this has been asked before.
I have a HTC Desire Z which I have rooted using the Cyanogen Wiki Method which i believe was successful, I wanted to check whether I was S-Off before loading custom roms.
wiki.cyanogenmod.com/index.php?title=HTC_Desire_Z:_Rooting
I read on a forum you should bootload to check, so i held power and VOL up on restart however now i have a black screen with a flashing red led at the top and am unable to get out of this mode does anyone have any advise what I need to do?
Anything would be helpful I'm in the UK military currently deployed on OPS this is my only means of comms to family. Thanks in advance.

Crap, so you're stuck in bootloader huh? Well if you have a PC with you then thats good news. Cause you can just flash something via your bootloader if you have ADB set up.
Wait, you said it has a red led lit right?... the battery might have died on you in all honesty because that's the only time a red/amber led would come on. If this is the case just leave it charging for like 20 minutes before try to turn it on.
Anyways, if that isn't the issue try getting the screen onto that bootloader page. As soon as you get to that you can start fixing it. It should say FASTBOOT_USB or something similar to that. Now on your pc start up your CMD Prompt (Run > 'cmd'). From there try typing Fastboot devices and it should list your device as HT########. If you can get to that then we're doing well.
BEFORE you try this, just note I've never fastboot flashed a ROM and I only posted this because you seem to need it urgently. If you can wait, then post what you've actually done to the phone so I can provide you with a more tailored solution that will work. (post whether the phone is rooted, s-off or superCID or just the guides and where you got stuck)
Now what you need to do is plug your microSD into your laptop and do this:

Before you do this please do the following:
1a. Download the RUU I’ve linked (it should be a ~300mb exe file)
1b. Run the setup until you get to the screen with the tick boxes
1c. Goto C:\Users\<your account name>\AppData\local\temp. Then right click and Sort By Date Modified. Look for the most recently created folder which should look like {xxxxxxx-xxxxxx-xxxxxxxx}. Then navigate into it and its parent folder. Look for rom.zip and copy that to your goldcard/memory card.
1d. Rename the rom.zip on your memory card to PC10IMG.zip
1e. Mount your sd card back onto your phone.

In this case you want it to be called update.zip. Now you can pop the microSD back into your phone and from there get back into your bootloader and switch to fastboot. Now when it says fastboot_usb you can run this on your PC's CMD Prompt. fastboot update /sdcard/update.zip

did you try something as simple as a battery pull? also, I noted you said power + vol up, you need to do power + vol down to enter bootloader. I seem to remember something similar happening to me back in the day.
chances are it's fine. I'd do a battery pull and boot it normally just to make sure, then power off and enter bootloader to ensure you are s-off by pressing power + vol down.

It is supposed to be volume DOWN + power, I just tried volume up, my phone vibrated 3 times and an orange light flashed continuously, but it was solved by a battery pull, and it was back to normal

HTC Flyer stuck on boot screen after 3.2 upgrade

Today there was an update 3.2 for my HTC FLYER so I downloaded it and started the install process. ( This was an official update as my rom is official )
So I started the install process and after some time it installed, and it started booting.
When it came to the HTC booting screen ( green HTC logo with white background) it stopped there and never booted to the Home Screen. I kept it like that for aprox. an hour but it didn't move from there.
Every time I rebooted it , kept stucking on the same point and never loaded on the home screen.
I tried factory restoring, through HBOOT but it kept transfering me to the HTC boot screen and kept staying there without going to the home screen.
My device was already S OFF .
I also tried connecting it to my PC with the USB cable but it didn't want to install the drivers. It failed every single time. I tried running HTC Sync but also it never recognizes the device.
Can anyone please help me? I can't even turn the device off, it keeps restarting to the boot screen and stays there for an unlimited amount of time.
With regards,

BUMP : Anyone???

I got the same problem. Anyone has a solution?

eric
got the same problem,can't even get the device to reset to factory,and the power light just keep blinking orange color,can't root to another OS either.
have tried the adb method and can't find the device.so can't do the RUU way.
anyone got any ideals?

I am in the same situation right now since last night... badly need to go back to the S-Off and phone feature running....

I've read about this problem in a german community. This workaround may work for you, but you do this at your own risk. I'm not responsible for any malfunctions or damages on your device! also note, that your sd-card will be completely wiped!
If you read the bold text above, you can try this:
plug in your flyer with your HTC AC charger
enter hboot
jump to "factory reset" with vol-down
HOLD vol-down AND power for ~30sec (after ~15sec the screen will be black with background-light, still hold down both buttons!)
after ~30sec the screen will be completely black
now you should see the green "arrow-ring", only now release vol-down and power
wait up to 10min and your flyer will boot properly

Got the same problem.
It's frozen: nothing works.
How do you connect it to the electrical grid?
Can you let it until the battery runs out?
Please help.
Thanks in advance,

Just plug in your HTC AC-power plug.
If you do that, your battery won't run out.

Edit: Removed, because question was answered above.
Thanks, woggly4

boot the htc flyer
If you plug in the AC-adapter it won't run out of power but you need to power it on to use it.
First download the recovery.img file for your flyer.
Then you need to setup the android SDK in your computer.
Boot it into the fastboot mode.
And then you run this commands from your command line
"cd C:\"the path where you have the fastboot file"
"fastboot flash recovery "the path where you have the recovery".img

Desire Z wont power on :(

Hey guys,
Running ILWT CM7. Flashed about two weeks ago. My phone has been working fine except for the past few days where it's been constantly freezing, requiring a battery-out and turn on, and rebooting on it's own.
Last time it froze, I removed the battery and turned back on, and it got to the "htc" logo and froze. After ~25minutes, I took the battery out and tried again.
Phone seems completely dead, won't respond to power on, volume down and power on, no lights come on when charger cable is plugged in. When USB cable is plugged in and no buttons or anything on the phone is pressed, my laptop attempts to install drivers.
Tried leaving battery out for 30minutes and trying again, but no luck.
Any suggestions?
Cheers!

Stuck in RUU mode?

Looks like your phone is stuck in RUU mode.
In RUU mode you see the silver "HTC" logo as long as your phone is connected to your computer with an USB data cable. No charging lights will show in this mode.
You can use the following command to boot your phone to Android:
Code:
fastboot oem boot
When that does not work, because your partition table or system partition might be corrupted, then you would have to use the correct RUU (Rom Update Utility) for your phone to get it back to a working state.
When you have a bricked internal memory chip (emmc) than nothing will work properly to restore your phone to normal working conditions.
In the case you have an engineering HBOOT you could boot a ROM from SD card, but that is a far shot.
Best regards,
Catherall

Thanks for the help
When plugged in with the USB cable -> computer, I still get no response from the phone itself. Screen doesn't turn on, still seems dead. My laptop still says "Installing device driver software" to no avail, and phone is still dead. No lights, screen is off, nada. As though it was powered-off.
ADB Devices lists nothing, and fastboot oem boot hangs on <waiting for device>.
Am I out of luck? I could send the phone off for repair, but as I'm rooted I think warranty is void.

Windows seems to need a driver installation for using fastboot. Did you try to automaticall install device driver software? Have you installed HTC sync on your Windows computer?
When your device does not respond at all, and even refuses to connect in fastboot, then nobody can tell that you have been rooted.
Best regards,
Catherall

Sounds like your EMMC is fried, as of now I don't think there's a solution other than sending it back. Many say HTC accept and fix it even though it is s-off

did you get this worked out? i had a similar problem, ended up booting into fastboot by holding the trackpad and the power button, then just selected reboot and my phone powered on like nothing had happened, i was running the same rom.

Hey, did you alreasy tourned your phone to the fastboot mode?
Or does your device still have a black screen during boot?

I rooted this phone and when I was done trying S-OFF, phone would not respond to anything. It would only blink the orange notification light when I pressed Power and Vol+, or it would stay steady green with both Vol keys and Power. But the phone screen would never turn on. So after trying for hours to figure it out. I finally took the battery off, plugged the phone held pressed the power button and then put the battery in place the phone finally turned on and it worked. I turned the phone off again and it was doing the same issue. So I did the same step but this time with power and vol- to get in the bootloader and changed the hboot version to Desire Z. After that phone works perfectly, turns on and off with out any issues.
I did have to try the trick a couple of times idk why but it would work once in a while not everytime i tried it. Hope this helps anyone who also ends up with a similar issue.

Desire HD bricked!

Hey guys,
I've flashed quite a few ROMs in the past 2 years. Today, I flashed a new ROM and it worked fine. After that, I installed Nova Launcher and changed the density to 160 and the phone asked for a reboot. However, it isn't booting after the reboot. I can see the white HTC screen for 1-2 seconds, after that the display dims and then turns off. Can't go into the bootloader or the recvovery. The phone charges normally (can see the orange light) and on connecting to the PC, it gives the successful connection sound. Any tips on how to fix this? I've done S-OFF long back if that helps. I've tried removing the battery and inserting after 5-10 mins, however I'm still getting the same output.

EDIT: Guys, just noticed that the phone isn't turning off after the HTC white boot screen. The backlight starts and then turns off after a second, and then starts again for a second and this keeps repeating..

Pull the battery.

Did you reboot holding power and volume-down?

Yeah, tried all possible combinations incl the usual power + vol down. The HTC logo appears for 5 seconds and then I can only see the backlight on the screen for another 2 seconds. This backlight then turns off and turns on repeatedly every 2 seconds and continues till I remove the battery again.
In short: No bootloader access, no recovery access. Just can see the device after I connect it to pc and type adb devices.

UPDATE: Fixed. Used the adb, on typing adb reboot-bootloader, I could access the bootloader. Thanks guys!

Same problem, Please Help!
My DHD, passes the HTC logo, then goes blank. The backlight doesnt go off, its just blank and remains like that indefinitely.
There is no charging led light when on the blank state,
The blank state does get detected by the computer.
Fastboot Commonader V1.51 says no fastboot device detected.
(P.S. My volume keys are water damaged and do not work, so i cannot use Vol- and power)

just try plug your phone to pc...then open cmd n change source to adb folder that you place..then type "adb devices" if your phone detected in there..then you can continue to next command type "adb reboot bootloader" or "adb reboot recovery"..next if you success go into recovery..just flash/ install another rom from there..
hopefully can help...

That worked. Thanks

Fail90 problem

Hi
I got today M9, and I did root and S-OFF thing, and later i wanted simply to update software manually.
I follow all instructions, BUT, when i got FAIL90 message, phone rebooted and - nothing.
Black screen, doesnt boot up, doesnt go to download mode, no "ding/dong" Windows sound for USB connection, simply, phone is DEAD.
When I expose it to a strong light, I can see only a single stripe on a display and thats all.
Is it bricked completely? Any ideas?
Thanks!

From what i read fail90 is a hboot preupdate issue. According to many sources a reflash is all that is needed but if the phone doesn't boot at all there's not a lot you can do.
I wish I stole my HTC M9.

You tried with vol up + power? I got this once when I flash new firmware, I use vol up + power, when the phone vibrate, release vol up and press vol down to enter bootloader mode
