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,

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
Sent from my HTC Vision using XDA

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.

[Q] My HTC Desire doesn't unlock...! Please help

Hi,
I've locked my phone yesterday and I've found a problem that doesn't let me unlock the device. I couldn't unlock and reboot the phone, so I took off the battery and placed it on and started up the phone. It freezed again on the unlocking. Tried this a couple of times - same problem. It has no wallpaper, the SD card reacts very slowly, the network also, and the screen doesn't turn off by itself if you don't do it so. Sometimes I can't even answer a call, it shows somthing like "Application not responding. Wait/Force close". I doubt it's the HTC Sense broken down or something similar. Please help me, I need my phone very quickly!
P.S. The phone is NOT rooted
Thanks!

You will lose all your data by doing this.
Boot into the bootloader (power off, press and hold volume down, press and hold power).
Wait for some green writing to appear and then disappear (about 7 seconds).
Use the volume down button to navigate to "clear storage", then press power.
Once this is done, reboot the phone and hope for the best.
----------------
If this doesn't work, make a goldcard (google how to) with any other android phone you may have, insert the goldcard in your desire
download the latest WWE RUU (look on resources in my guide)
boot into fastboot mode (hold back & power) and plug it in via USB to your PC
Run RUU.exe and do not touch the phone til it completes.

Well thanks man for the work, but I'm kinda n00b at all these phone system stuff, is there any other way that has less consequences than this, I mean, no losing all the data stored?

no, not without a properly functioning device.

[Q] Need HELP PLEASE!!!...USB Issues/Stuck in HBOOT

a few secs after the phone starts up it flashs PB99diag.zip and pb99img.zip missing
the buttons on the phone do not function
I have tried installing android-sdk, htc sync, hboot drivers and cannot get the phone to found when on my Windows 7 64 bit machine, so I can push a new pb99img.zip to the phone...but i cannot get the phone to be found.
In device mananger it shows up as Android 1.0.
I can manually install the drivers but adb will still not show the device as listed.
The phone is not in USB debugging mode since none of this was intentional.
If anyone has any tips or advice it would be most aprreciated.

Did you root the phone previously? Did you install a custom ROM on it?
What you see is the HBOOT menu. To move the marker down you press the volume down button, to move it up you press the volume up button, and to make a selection you press the power button. Can you tell me if this works?
What happens if you take out the battery, put it back in and press the power button? I doubt it that the phone enters the HBOOT menu on it's own. Is that what you are saying? Normally you need to press and hold down the volume down button and the power button to enter this menu. So to stop entering the HBOOT menu just stop holding down the volume button when you power it on. If it enters HBOOT menu by its own will then something is wrong.
When you enter the HBOOT menu the phone will automatically look for a file called PB99img.zip or PB99diag.zip. This is sort of a fail-proof mechanism. It allows you to flash images or diagnose the phone when everything else fails, like in the case you loose button control. If it doesn't find any such file it will skip the operation. This is normal. It's the equivalent of putting a bootable CD or DVD in your Windows computer - if it's present at system boot it will boot off the CD/DVD and if it's not it will just skip it and continue booting current OS.
As for the ADB driver, check this out. You may need to change the hardware IDs in the driver INF file (android_winusb.inf).

Thank you for the quick reply...apparently my mother spilled something on the phone and it was acting up a little so she powered it down and when you powered it back up it came up to the HBOOT screen. The phone is stock it has never been rooted and no custom roms either. When I pull the battery the phone turns off, I can then put it back in and press power and then i am stuck at HBOOT. Once on the HBOOT screen none of my buttons function, not the volume or power buttons none of them. I have made sure to only press the power button when powering up and yes it still enters HBOOT. Thanks for the link on the adb driver info I will check it out with all haste.
Thank you for ADB driver info it was truly appreciated...my Hardware IDs are correct...the driver installs as Android ADB Interface yet adb or htc's ruu utility neither one acknowledges the phones existence. Is is possible that the phone is hosed?

have you tried selecting fastboot and then selecting reboot?

Flash the stock HBOOT image

I'm thinking that maybe... only maybe... the spilled liquid was sticky (and surely conductive) so that the volume down button is kept depressed, so when you press the power on button it acts as you are pressing volume down and power button. It's probably far fetched but it is possible that the volume down button is depressed for one or another reason.
Yes, I think it will say like "Android ADB Interface" when you plug the phone in while in HBOOT. It will say something else I think when you plug it in while in recovery, etc.
I don't think you can use ADB commands while in HBOOT. I think ADB commands only work when the phone is booted up. If you can enter fastboot mode you can use Fastboot commands to flash a new HBOOT for instance.
But since you can't control the interface at all and no button seems to work on the phone, I think you have to try flashing a new HBOOT by placing a ZIP file on the SD card.
Go to AlphaRev website.
Download PB99IMG_stock.zip
Rename it to PB99IMG.zip.
Take out the SD card and put it in the computer.
Copy the PB99IMG.zip file to the SD card.
Take out the SD card and put it in the phone.
Insert the battery and power on the phone.
It will now automatically flash it with stock HBOOT image. Keep in mind that this may or may not erase personal data from either the phone or the SD card. I don't take any responsibilities for any data loss. I know you can't access the phone apps and internal data right now, but you can at least take a backup of the SD card, most apps are storing data on the SD card so you could use that to restore at least parts of the data later.

No, no, no. Whats flashing hboot going to do? the phone is "water damaged". Also his phone is s-on and never rooted and u can only use alpharev hboots while s-off. Also he has a BravoC so i dont think Alpharev hboots work. Please learn some basic stuff before telling other to do things that r wrong and wont work.
@ OP i have no solution really apart from taking the phone apart and cleaning it maybe. but its water damaged so i think the only solution would be to run the correct ruu for ur phone and hope it boots or take it to a repair shop. If it was me, i would take it apart, clean it, put back together and try the ruu for ur device. But thats just my opinion. Seeing that the phone is not working then its prob worth a shot.

Ooops!! Me bad... sorry! Thanks for correcting me though. So his only option is running the RUU for a BravoC?
Where can you find RUU for a BravoC? On Shipped-ROMs I can only find BravoC for AllTel, Verizon and VZW. Do you have to take carrier name into consideration when choosing RUU? Are there no BravoC that are not locked to a carrier?

Nice suggestions, but I'm pretty sure the phone is just physically broken. Take it in and see if you can get a replacement/fix. BravoC is hard to wrestle with.

Thanks for all the suggestions...I had tried running the ruu from htc, but since i could never hammer out the usb issues the utility kept saying that the phone has less than 30% power and would promptly fail...anyway mom decided to turn it in on the insurance so its all a moot point now...again thanks to every one who tried to help and all the great guides/info on this site at least i learned quite a bit...

Just another person who has Hard Bricked his M8

Hello Everyone
TL;DR Screen doesn't come on at all, battery led only flashes while it is rebooting (More details below), and When plugged in to my windows pc, a bunch of "Local Disk Found" pop up, some of the volumes I can access, most I cannot.
I have searched and searched the internet the past 24 for solutions, and have yet to find one. So imma walk you through what led up to the issue, as well what solutions I have tried.
Yesterday while I was trying to update my rom, I ended up getting stuck in what I thought was a boot loop. I then decided to hard reset my phone and go into recovery in hope to try to reinstall the rom. To my surprise, I could not access the internal sd card in the phone. Data was unmounted in the "Mount" settings and I could not what so ever remount it. After this I tried to side load it, but to no avail.
In response to all my attempts to fix the phone at that point, in frustration, I just said "**** it" and went into factory reset in the bootloader. This is where the hard brick happened. At this point, the screen would not come one, and the battery led was not lit when plugged in. I tried letting my phone charge over night and then, tried the "Battery Recalibrate method". I then tried the "Hold Pwr + Volume up for 10 seconds, then Power + volume Down until you access the bootloader"
After that, I then thought that the firmware was corrupted, so I tried to see if I could push an img to the phone, however fastboot does not see the device. I tried RUU, it does not see the device. I tried the HTC Unbrick method by Dexter that required me to install ubuntu and do some things in terminal, that also did not find the device. And here I am stuck. One thing unique to my situation that I have yet seen reported in the countless threads I have searched, is that when I plug my phone to my pc, a large amount of disk drives are found. Most of them are not accessible, but there are a couple that I can go in and see files for. Windows asks me if I want to format the ones I can't access. When hooked to my pc, I tried the the Power + volume button combinations, the only thing that seems to happen off of this is that my phone seems to reboots, and the battery indicator briefly shows.
Anyways, this is all I can remember. Any help would be GREATLY appreciated. I don't really think it is a hardware related issue since my phone does somewhat boot. However it seems it can't get to a bootloader what so ever.

Try holding power and vol up for a long time, like a minute or more. Try with and without charger attached, and after sitting on charger overnight.
If the bootloader is intact, the phone is likely not truly bricked (recoverable). And I don't see how you could have damaged hboot by the actions you mentioned.
What is the phone's original CID (carrier version) and are you s-on or s-off?

Verizon is the carrier version, and I am s-off.

Held vol + up for 5 minutes both with and without the charger. One time with the charger into my computer, and another into the wall. When it was in my pc, I can tell its doing nothing but rebooting over and over by the notification sound, and the constant "Found new disk" notifications I got. However still no luck, no screen turns on, no sign of hboot. I'm hoping to have some luck after leaving it on charge overnight and trying again.

So still nothing after leaving it on charge overnight and I held vol + up for about 5 minutes. Things seem grim.

I think the proper thing to do when you discovered internal storage was not mountable, would have been to use the TWRP option to format internal storage (in Advanced Wipe options).
But now I'm baffled as to what happened that would have rendered the phone unable to boot into fastboot mode. Fastboot won't recognize the device if you can't boot into fastboot mode, which leaves use kinda stuck.
So you didn't try to flash anything during the course of all this troubleshooting?

What you did - "Hold Pwr + Volume up for 10 seconds, then Power + volume Down until you access the bootloader" is totally wrong
I used to get this bunch of local disk pop-up and this is how I get out the problem
Connect the device to pc, you can hear notification sound on pc that device is connected. Ignore all those bunch of local disk pop-up
Press & hold both power button & volume up button until you hear another notification sound that device is disconnected from PC (that's the indication that device is restarted)
Release both power & volume up button and quickly press & hold volume down button (only this one button)
This should get you on bootloader

No, nothing was flashed except the original Rom update that got this snowball rolling (Not saying its the roms fault, most likely mine).

This is the one combination I forgot to mention in the op, sorry for that.
But I have tried this, before and after your post, still no luck.
If it worth mentioning, I can just hold power + down and it still reboots over and over. As well as just power. As a matter of fact, all button combinations reboot the phone over and over.

By it constantly connecting and disconnecting from my pc. If that doesn't mean its rebooting, then I guess I'm mistaken.

Well, it might mean that.
If it in fact is rebooting over and over on its won, simply holding the vol down button for a long time, should put you into bootloader (on the next reboot "cycle"). Again, assuming it is in fact rebooting, and that bootloader is intact.

HTC M8s wont start even fastboot aftrer unlock bootloader and flash recovery

I get new HTC m8ql_ul, first i unlock bootloader succes. Then flash twrp-recovery-2.8.6.0-m8s-qlul also with no problem. In TWRP i flash new rom, but gets problems. eg after start didnt see sim card. And after plug to comp, and set data transer not charge pc didn see my phone, also in twrp cant see or fastboot also. I tryed fiew times flash difrent roms. but also same thing : when install via aroma, never get 100% but eg stuck at 30% after fiew sec show 100% and info about succesed flash but stack on HTC logo.
But now when i off phone pressing ~10s power, afrer this push power + V+ and nothing, no bootloader no flashboot no reaction, when press only power phone start display big battery icon and thats its, must ~10 power to off icon, even not plugged to pc.
What can i do? Flashboot didnt see phone. Pliss

for me plugging my HTC one m8s into an wall outlet, and pressing the volume down and power button gets it to boot into recovery, im no expert at this by any means, but hopefully this helps!
