Go to settings->battery and turn off fast boot before shutting down and doing it. Otherwise it boots straight to android.

[Q] incredible brick

My Incredible is bricked. It powers on and stays at the white screen that says "htc Incredible" no recovery, no bootloader, nothing. All I did at the time was place a rom on the root of my sd card then tried to flash it. From there I got this damn white screen of death. Is there a way to possibly salvage this expensive paperweight or do I have to go buy another phone?
Any help would be greatly appreciated.
You can't even get into bootloader? (Reboot while holding power and volume down).

adb is your best friend. adb reboot recovery, adb reboot. can use those instead of pulling battery

Try from a completely powered down state, as opposed to a reboot.
Edit: yes, I know that's what you meant, but he might not.

Completely powered down if I hold the volume and power button it vibrates 3 times and I get nothing after that just a black screen. The only way that I can get it to come on after that is pull the battery and and just use the power button only.

Not sure exactly. A friend of mine got me back into recovery somehow. From there I was able to flash my backup. I wish I knew how he did it.

I'm in the same boat. I accidentally loaded an Incredible S ROM. I can get into hboot, but any of the options just take me back to the white screen.
Try plugging into the computer with the battery out. That could get you bootloader. It works like that on most androids.
Thanks for the tip, but unfortunately it didn't work. A buddy of mine said "If your hboot will let you switch into fastboot, then u can search on XDA there should be a way to wipe and flash a command line through usb if u can get fastboot" but I couldn't find anything on here about a command line. It does let me into fastboot.
Also it recognizes when the USB is connected.
Do you think that you could flash back to stock?
If you can get into hboot, you're all set. Go here and get the PB31IMG.zip file http://dougpiston.com/?page_id=108
It's the RUU that will bring your phone back to stock. Put it on the root of your SD Card (use a card reader or any other way of connecting the sd card to your computer). Make sure it's labeled exactly PB31IMG.zip or it won't work.
Then put the sd card back in your phone. Get it back into hboot. After a few seconds it will ask if you want to update, press volume up to start the update. It will reboot and all will be fine again!
Thank you soooo much. It worked.

Volume DOWN and power. Volume up and power does a hardware test where that is the response you should get. For it working.

Hard Bricked. Help

Seems I have now flashed wrong bootlader and my phone wont turn on. When attempting to start it just powers the screen for a millisecond and repeas this over infinitum.
Is the anyway to fix it please.
What exactly did you do before? How did you flash the bootloader?
put it onto an sd goldcard and loaded it up. My phone wont turn on. I can hold vol up and down simultaneously with a tap of the power button, then i get 5 vibrations.
If I hold vol up and tap power i get 3 vibrations from the phone.
Is the still hope for me yet. Please help.

I seems like it's got into a Qualcomm diagnostics mode, hence the 3 vibrations.

[Q] M8 Dead/Bricked/Don't Know !!

Hi All,
One of my friend got M8 and one fine day phone went to bootloop automatically and then he rebooted the phone into bootloader and did a sideload of custom rom/may be stock back (he don't know actually) but he said he flashed TWRP. Now after flasing the ROM the phone never started.
Issue is now the computer also did't recognise the device. If I plugin into the wall charges sometimes orange LED glows and sometime not.
It also not booting/ Not going to bootloader. Please help me to fix the phone as it's a imported version from US and indian service center will not help this.
Many thanks in advance,
Mahesh
Did you try volume UP and power until the 3 soft keys stop flashing? That is the equivalent of a battery pull. After the soft keys stop flashing then try to boot to recovery or bootloader. I haven't used ADB Sideload, but I would try using the microSD card to flash a new ROM.

i suppose you tried volume up and power together?
Yeah you'll have to get an SD card and then put a ROM on the SD card with an adapter from your computer...hold down both volume keys and power button for 10 seconds and then hold down vol down and power right after and go to recovery, wipe and flash

Yes mate, I tried that combination power+vol. down. Nothing happens.
And it won't power on in any way?

Press and hold Power + Volume up for about 10-15 seconds. Does anything happen?

Odd how it starts bootlooping so you automatically install TWRP and flash a rom and don't think 'why was it bootlooping in the first place?'. Now you voided the warranty
Sorry bud. It's bricked.

Did he tried htc one m8 toolkit? It has options to push to the device command to reboot, or enter recovery.

It just uses adb, which will not work in his phone in this state. Toolkits are never a good idea for troubleshooting.

Just one question, are you having a bootloop or the device wont power on at all? Do you feel any vibration while holding Power+VolDown?
Did you unlock your bootloader before this happened? If you didnt, you can still return it...

It's not powering up at all. No vibrations. As its a Developer edition so bootloader was factory unlocked.

Flashed bad Rom while porting

I was attempting to port SlimRom for the Desire 816, and I stupidly forgot that the one m7 had a different screen size. As a result, the phone screen doesn't work. I attempted to reboot into recovery, except for that you need a complete off and volume complete off and volume + down. with no screen, all I can do is reboot. adb is no help either. Please Help me!:crying:
Hold volume up+power. The phone will shut off.

Once you see it power off let go of all the keys then quickly press Volume Down+Power and it will allow you to get into the bootloader. You can then proceed to the recovery from there.

Iv tried but it doesn't seem to work. I was able to drain the battery so it might work now
Update: I fixed it, the only way was to wait for battery to drain and then go into recovery...

HTC won't boot

I tried to root my HTC Desire 820. While rooting it with supersu i checked reboot system instead of wipe cache/delvik (which is probably why it wasn't detected as rooted). I noticed it, so I went back in, and while choosing .zip directory i went away for ~5mins and now my phone doesn't boot (LED doesn't blink either); battery is well over 80% and charging. What should I do?

Reboot a couple more times, or is that blank screen caused by the TWRP screen saver?

Well if I had to guess I'd say it's a screensaver because I didn't really press anything; I can't access it in anyway, unless there is a special type of button combination?

Try holding power and VOL+ together for some times. It should then bring up the HTC boot screen. Then the device should start boot normally again.

So I guess Volume down doesn't work that way? I tried pressing vol- and power but it didn't work, haven't thought about vol+. Thanks a lot for saving my ass.

You are welcomed?.
For most of the Android device that has a non-removable battery (not by screws), VOL+ and Power button is a universal trick to force reboot/shutdown your device.
