Desire un-responsive - Please Help

I've seen a couple of threads such as this with no real solution.
I've been happily using my Desire for months without changing roms or whatever (CM7 and s-off) until last night I opened my Dolphin browser and before it loaded the homepage it froze, totally un-responsive. I took the battery out, and to my horror, it was still totally un-responsive. Wouldn't respond to pressing the power button, pressing volume down+power, charger, or usb.
The battery at the time was about 50%, I've had the battery in and out about 100 times now, trying things like leaving the battery out and then trying again, keeping it on 'charge' for a while and trying to get it booted, with no response at all.
This was until an hour ago, I hopefully tried to boot the phone after the battery, sim and sd card had been out for a while and I got a vibration, and then it hung on the flash screen. I had to remove the battery, then tried to boot again with no response, so I left it a while again, put the battery in and got to the bootloader, thought I'd get into recovery and try a nandroid or something, only when I selected recovery it hung on the slash screen again.
Does anyone have any ideas what this is, or how this could be fixed? Damn I hate not being able to use my previously awesome phone!
I apologise for the long post, I'm just trying to give a good explanation of things. I just couldn't see the problem being my battery, only the day before the problem I was telling my friend how great the battery life on my phone is, and that he should give rooting a go and use CM7, this probably hasn't swayed his decision to root his phone.

did you try rebooting it without sdcard?

If you manage to get it running , try to flash a shipped ROM - it should unroot you and fix any software problems . Try taking it back to your carrier as that sounds more like a hardware problem.

you are stuck on HTC screen are you not? Then this is the exact same situation is it not?

"I'm S-ON, I can't boot recovery, and my phone doesn't boot "
This is a bit of a worse situation, as you cannot flash system critical parts such as the recovery image and just restore a backup. This unfortunately means that you will lose all of your data when you attempt to fix the phone.
[STEP1]- Make sure that you have a goldcard. If not, create one from the tutorial.
[STEP2]- Battery pull. Hold the BACK button and the POWER button to boot into FASTBOOT mode.
[STEP3]- Download the latest WWE RUU from here
[STEP4]- Run the RUU and wait for completion WARNING: DO NOT, BY ANY CIRCUMSTANCES INTERRUPT THE PROCESS - THIS WILL MORE THAN LIKELY END UP WITH A BRICKED PHONE - NOT EVEN IF GOD HIMSELF TELLS YOU TO DO SO, OR IF THE US PRESIDENT THREATENS YOU WITH THERMO-NUCLEAR WAR
[STEP5]- Once the phone is booted, you are now returned completely to stock. You will need to re-root again, and I'd recommend S-OFF

I've changed the HTC screen to a Google one, but yes, formally the HTC screen.
I will try and get to the bootloader/fastbootagain, only I have not been able to get to that today. I'm going to download an RUU, and try and flash it, although I'm not sure how if I can't get into recovery? Any help there?

up to you, doesn't make a difference

Thanks for the help, unfortunately when I got the RUU downloaded and the bootloader downgrader I now can't get the phone into fastboot! Rather gutted, as I could get it there the other day, now I may have to accept defeat!

What happens when you try to get to fastboot mode? How do you do it? Try to boot into hboot, then press power button and you should be in fastboot mode.

I have been onto them. The response from HTC was amazing, after detailing in an email my phone is dead, won't respond and won't turn on.
I was told, 'while the phone is on, remove the battery and sim and perform a soft reset, if this fails, perform a factory reset, through settings'
I replied asking them how much it will be for them to fix it, they haven't replied! Maybe they don't do weekend!
So if I send it off to them, are they going to frown upon me for fiddling with the phone and rooting etc?

I think I just ****ed my phone

All was working fine until I installed the 3-dot removal on ODEXED rom then it will never boot again! just hanging on boot. so i ****ed my recovery aswell. All i have now is fastboot which is always telling me BATTERY TOO LOW no matter how long i keep it on charge. I can't flash anything neither use RUU. When I click "switch off" in boot menu it will just restart and bootloop. I don't know how to charge my battery so I can use RUU again. Please any help will be much appreciated!

Exactly this version. But I've seen odexed later after I installed it.
I was able just to "erase cache" and unlock it. Then flash recovery. Now its in recovery and I'm waiting for it to charge. Hopefully it will.

Once you have the latest CWM you can charge the phone whilst it's off. After that you can flash a ROM/run a RUU and get it back up and running.

I've tried everything. Now im at phase in bootloader - battery very low again. It's not charging from bootloader neither when I start it. Recovery is not working too + I can't unlock it because of the battery. Tried to shut down - not working. HTC made that phone crap because of the internal battery! I hope there will be solution or I have to return it to them,.

To be fair its not HTC's fault, you did do something that they didn't intend.
Also don't charge from the bootloader it needs to be completely off, hold power and volume up to force it off.

I put it in bootloader to charge - it failed and switched off. Turned on bootloop to charge - same story. Tried with clockworkmod latest - same story. So I was going to send it back. Until I switched the usb port on the PC - then the battery problem was not there! I WAS ABLE TO USE RUU! That's how I fixed it.

[Q] One M8 Stuck on Logo...Period

I am in need of some serious help. My AT&T M8 won't boot past the HTC logo screen and won't allow me to go into recovery or the hboot screen. I believe I may have wiped the OS on it; this is the only thing I can think of that makes sense. Furthermore, when I try to power down the device by long pressing the power button, it doesn't respond at all. It just stays on the logo screen. It was so bad that I just left it plugged in overnight and I don't have a clue as to how long it took to power off because I fell asleep before it did. If there's a video tutorial out there that someone has or simply a link that can show me how to install something via backdoor on this device, that would be great!

Hold power and vol up for several seconds to force a reboot. The moment the screen goes dark to reboot, let go of those buttons, and just hold vol down. Don't let go until the hboot screen appears.

Thanks already. I didn't realize I had to hold down the volume down button after it goes dark. It got me into twrp. I believe I should be good from here after I download a new rom to sideload. But to give you a run down, I was prepping the phone to sell it by wiping the data and installing the rom the guy said he wanted on it. When I was going thru the normal procedure to install the rom (wipe, flash, etc) that's when the phone started sticking on the logo screen. My assumption was that I downloaded a bad rom, so since then I've been trying to get back into twrp so I can load a new rom and finally was able to after you told me this. I'll report back if a new rom actually didn't help the situation. I only thought I wiped the OS because something similar happened with my Note when I was tinkering and that was the result.

So, it seems I'm still having the problem, even while trying to install cyanogen. Here are the answers to those questions...
1) bootloader unlocked?... YES
2) custom or stock recovery... TWRP
3) custom ROM?... It was a custom AOSP Rom
4) what hboot number?... 3.16.0.0000
5) s-on or s-off... S-OFF
6) did you make a nandroid with custom recovery?... It was erased
Any help you can give from this point would be awesome. Thanks again!

Failure to flash ROMs can often be solved with fastboot erase cache, then install TWRP by fastboot again. Update TWRP version, if you are using an outdated one.
Also, if you try to flash any ROMs based on Sense software beyond version 1.x (huge majority of them are past 1.x at this point) you will likely experience extremely long boot times (10 minutes or more) and broken WiFi due to outdated firmware. But CM should be okay.

It was erased, or you wiped it?

Okay. Do you suggest trying an older sense rom to see if it works? The last time touched the phone was when I picked up my Note 4, so I will look for something that predates that.
As for the nandroid being erased, I can only assume it was my actions that caused it to be deleted, but I don't recall intentionally doing it.

Sure, it couldn't hurt. With your current firmware, you will need a ROM based on 1.x software. There aren't a heck of a lot of those left. But there are a few. GoldenEye is one I can personally vouch for, since I was running it for a while back in the day:
http://forum.xda-developers.com/showthread.php?t=2705640
But I would definitely recommend just trying fastboot erase cache and re-install TWRP first. I've lost count how many times suggesting this simple fix has helped other users here on XDA, when ROMs fail to flash.

Fair enough. Just FYI, don't do a factory reset in bootloader (in the OS settings or recovery is OK). On modded phones this may cause the internal storage to become corrupted. Nandroids have sometimes been lost this way. This may or may not be what happened to you. Just wanted to throw that out there.
Also, there has been the occasional occurrence of internal storage being corrupted, possibly by TWRP. It may not even have been something you caused.

[Q] flashed tmo on att d850 HELP!

I just flashed a rom on my d850 and now the screen wont turn on the phone is completely unresponsive I don't know what to do I can't even get the phone to boot some one help me im sure I just bricked the phone..

First, what rom did you flash and how did you flash it?
Try this as well:
Pull the battery, press the power button for a few seconds. Put the battery back in and press the power button again. Pop the battery out a 2nd time and then put it back in. See if it turns on.
If that doesn't work, pull the battery and hook the phone up (without the battery) to a computer and again see if it turns on and shows up in device manager.
Flashing the wrong rom should only result in a non-booting situation. If you have a custom recovery installed, you should be able to still get into that. The d850 has some serious issues with successfully rebooting in general (which can be resolved by the two suggested procedures above), so I would suspect that before worrying about a brick.
Lastly, the d850 requires bumped ROMs to get by the locked bootloader. The d851 (T-Mobile version) does not have a locked bootloader, so the roms are not bumped and will of course fail to boot.
Once you get back into recovery, just wipe all partitions except for internal storage/sd card and install a correct rom.

If it is on and showing up as a phone in Windows, why not just use the LG recovery tool and flash back to stock, then start over?

My HTC M8 Stuck at ONE Logo once restarted. No Recovery, No DWNLD mode available.

I've seen already this thread suggested by XDA thread locator.
https://forum.xda-developers.com/htc-one-m8/help/verizon-htc-one-m8-stuck-htc-logo-t3163088
But I'd try to explain as simple as possible the whole situation which happened hours ago.
Don't know what happened but my mothers phone went off and restarted with htc one logo on it and nothing else later.
Power button itself doesnt work and is not responding.
Configuration PWR + VOL UP gives me restart but no recovery mode, giving me sound effect of restarting phone and ONE logo on it without any other reaction whatsoever.
PWR + VOL DWN zero reaction
PWR + VOL UP & DOWN pressed together restarting the phone and then gives me HTC ONE LOGO and nothing else.
when Phone is plugged in to the computer and I'm forcing the phone to restart it shows me new Device on the computer as a CD Driver every time.
So I think there is still hope to get this guy back to life.
It's running on custom rom but unknown version because it was purchased as a refurb from ebay 2 years ago and it was running just fine utill this very day.
I'm absolutely noob with flashing twrping etc so please ELI5 if possible, any type of help will be much appreciated.
Thanks in advance.

Hey, I had this same problem a couple of days ago. Here's what I did to get the phone into fastboot, from where you can install a recovery, factory reset etc.
1. Hold the power button + vol up button for about 10-20 seconds. This should shut down the phone.
2. Hold the power button + vol down button to restart the phone back into fastboot.
If you can get into fastboot, there are plenty of guides which can help you flash a twrp image. If you want me to give you some instructions on that just reply and let me know. Good luck!

Note that this phone doesn't have download mode (as some other Android devices do); nor is there a button combo to go directly to recovery. But you can almost certainly still get to bootloader, and from there boot recovery. In the current condition, you can get to bootloader by:
1) Hold Power+ vol up (as you have been) to restart the phone.
2) Once the screen goes dark (signaling it is about to reboot) let go of the buttons, and only hold vol down
3) Don't let go of vol down until the bootloader screen appears.
4) If the above sequence fails, its virtually always because the user just didn't get the timing right (either started pressing vol down too late, or let go too early). Just repeat steps 1-3 until you get to bootloader.
Once in bootloader, try to reflash the ROM, or restore a TWRP backup (if you have one). Spontaneously stuck on HTC logo screen is often a result of the OS/ROM becoming corrupt or otherwise damaged, and flashing/restoring the ROM will often fix it.

Thanks @redpoint73 I've managed to get to the preinstalled recovery.
Sadly reflashing/factory reset failed few times due corrupted files.
I'm ok with the fact that I lost the data on the phone since most of it was stored on the cloud.
Now I need ROM to flash on the phone thru recovery but I don't know which one would you reccomend.
It's my mom's phone so basically reliabilty and robustness over flashing lights and numerous unnecessary functions.
Version of android doesn't really matter.
Thanks again for help so far.
Can I put the rom I'm about to flash on external SD Card or I have to transfer it thru computer to the phone?
TWRP might be extra helpful or the recovery it's functions are just fine?

I'd need to know more about the phone in order to give any suggestions.
With the phone connected to computer, boot into fastboot mode, and (assuming you have fastboot setup on your computer) do the command: fastboot getvar all
Then post the results (delete IMEI and serial number before posting).
Also, what version TWRP (if that is the recovery installed)?

You have what is called the "stock recovery" or official HTC recovery.
You can't flash anything but OTA updates, or other official (HTC) signed zips with this. You need a "custom" recovery like TWRP in order to flash things like custom ROMs. So I'm curious what you meant before when you posted:

I did the factory reset but it didn't help still stucking at ONE logo like posted initially. So this is basically the situation right now. I was able to get to recovery but nothing else.

Okay, so you're confusing the terms. Factory reset doesn't flash/reflash anything (flash meaning to install some firmware or software to the device). The only thing that factory reset does is wipe user data.
At this point, I'd suggest the best/easiest course of action in the current conditions (stock recovery, locked bootloader) would be to run the RUU intended for your device. Your device is the AT&T version, so the RUU can be found at the bottom of the page (and instructions on how to install): http://www.htc.com/us/support/htc-one-m8-att/news/
RUU is a complete factory image. You download to a PC (PC required, won't work on Mac or Linux) connect the phone (booted into bootloader-fastboot mode) then just run the RUU, and it will do the rest.
I'm confidant this will get the phone up and running. Your mom may not like all the AT&T branding and apps, if it wasn't there before, and AT&T is not her carrier (one of the main reasons for these devices to have custom ROM - to remove carrier branding). But we can cross that bridge (if need be), after we get the phone working.

Installed Software, downloaded RUU from website provided, turned phone into fastboot before installing RUU.
Something started happening with the phone during installation but installation itself cant be finished, it's an endless process of update, phone is already plugged 3rd hour or so to the computer but the update status remain the same.
Should I try different approach?

It just gets stuck sometimes. Just kill the process, and start the RUU again. It will probably work fine on the next try. It's a bit scary, as it says not to stop the process or disconnect the phone while it's running. But if it gets stuck like this, there isn't anything else you can do.

Good News, it's working. But it's bloated to the bones. How I can get rid of the carrier unnecessary software?
I was to afraid to kill the process during update to avoid scenario of bricking my phone completely.
But It's working!
