[Q] Htc one m8 black screen, won't boot up PLEASE HELP - One (M8) Q&A, Help & Troubleshooting

So, I tried to restore a backup from TWRP. During the process, the system and cache were restored fine, but couldn't restore the data (for some reason, it said failed), so I figured it's alright, I'll just have to install all the apps again, no big deal. But, after I clicked the "reboot system", the screen went off and never turn back on.
I can't get in bootloader screen in any way, I haven't tried the Vol up + power button for 10s, and the vol down + power button, and the 3 button all together... Nothing works.
When I press the power button normally, nothing happens, not even the Htc logo screen.
When I plug it in, it only shows the battery charging icon. So I tried the buttons combination again (coz I thought at least the screen turns on now), but still, nothing happens, just the screen switch between black and the charging icon.
So, I left it charging overnight, and tried the buttons combination again, nothing works still.
Now I have no idea what to do, can anyone please help me?

It sounds like you hard bricked your phone. Try using this guide youtu . be/ rpA71FXddyU[/ but Im not sure it will work.
Only thing what you need is that computer recognize your phone, because when It doesnt then you should take your phone to local phone repair.

[Q] Stuck in bootloader, HELP

My phones stuck in bootloader and it doesnt respond to both my volume buttons and my power buttons. Anyone have any idea how i can fix this? Also when it boots up it looks for a file called pd98IMG. Ive tried putting it onto my sd and the phone boots into bootloader and loads the file but it still stays in bootloader.
The phone is also rooted and i was running android revolution
Anyone who has the answer to this gets a reward, most likely to be cash. Thanks
Pull the battery, put it back in and power and - volume down should see you to recovery and just reflash your current rom.
It doesnt boot into recovery when i do that, it just boots into bootloader every time
I think i had the same problem a while back, the trick here is speed As soon as you put the battery back in try and get into recovery.
Take the battery casing off and the battery slightly out, now push the battery back in and press the bottom of the volume slide and quickly hold the power button down for a second, than release the power button still holding the volume down, you should now be in hboot, wait 2 seconds than go to recovery.
thats not working either, you got any other ideas?
Would you have adb?
Try this http://forum.xda-developers.com/showthread.php?t=1304940&highlight=stuck+in+bootloader
i get error:device not found, how do i get rid of this? :s
Is it still bootlooping? There should be a sweatspot where it works just as the led lights up, simply a matter of timing. Though i would give the battery out hold power and volume down and put battery in approach another go if all else fails.
nope, my laptop doesnt recognize my phone as its in bootloop so therefore i cant really use adb with it or anything,
Just want to make sure, as soon as the phone is powered off, it goes back on by itself automatically? If so take out the battery plug it in put the battery back and try to boot into recovery with charger.
i cant power the phone off using the power button, i have to remove the battery since its stuck in bootloader and the power and volume buttons dont work in bootloader for some weird reason

HTC One M8 hardware buttons working weirdly

Hello everyone! So I've had my phone (HTC One M8) rooted and custom recovery and rom installed for a little while now. The latest rom I've installed was Android Revolution HD 22.1. I also have twrp 2.8.1.0 installed. The other day my phone got wet and started to constantly reboot itself, wouldn't shut off and stay off, would never actually start. I put it in a cup of rice for 2 days, then proceeded to plug it in to charge it. Once charged enough I tried to turn it on. It only made it the HTC One logo screen and would vibrate every 10 seconds or so. I tried rebooting several times and no matter what I did with different button combinations I could not get it to load into bootloader. Eventually with restarting different ways and "mechanically stressing" the phone (short temper lol) I managed to get it to loading into the rom itself. From there I opened hasoons all in one toolkit to reboot directly into recovery and recovered to the stock rom. So the phone will now reboot with no problem into this rom. I haven't tried reflashing the ARHD 22.1 rom again because im afraid it'll break again. However, while in the stock rom everything work fines except for the volume up button which does nothing, except for while the screen is off, if I turn my phone to landscape the camera app will open without me even pressing the volume up button. If I reboot into bootloader via the quickboot app or hasoons toolkit, my volume down button with make the cursor go up, the volume up button does nothing, and the power button does nothing. The only thing I can do in bootloader is to hold power+volume up to get the phone to reboot. I also cannot get bootloader to load by holding volume down+power. So, After all that explaining, my main question would be, do you think that the buttons are shorting in a weird way because of water damage, or do you think my software got corrupted because of all the rebooting it did? Any help is appreciated, thanks!

UPDATE: my power button will now lock my phone but not unlock it.

HTC M8 stuck problem.

I rooted my phone like a month ago and installed TWRP. After ARHD i wanted to try MIUI, but when i flashed it i lose my root. I m downloaded ElementalX 4.4 gpe kernerl and i go to flash it, instalation go normaly, but when i finished twrp lagged for first time 2,3 secunds when i tap reboot. After that, phone booted normaly, white display with htc and developer text, like always, but after that come black display. It stucked here and i cant do anything. No matter how long i hold power button or anything else it cant do anything. It dont shows orange light on charger. 2 hours i cant do anything, but phone is running something, it is hot right now, cca 41 c, but its still stucked. Please help.
a
finded out now, when am hold power buton + vol up, phone just restart, and stuck like last time. It cant boot to recovery or bootloader
Hold power + volume UP, as soon as the screen goes BLACK switch to volume DOWN. Keep the POWER button pressed at all times.
That will put the phone in the bootloader, go from there to the recovery and reflash a rom with a FULL wipe otherwise it will never work.

HTX One X, Frozen, No Bootloader, No Power Off... suggestions ?

HI guys,
Hoping you guys can help me. I have a HTC One X I picked up 2nd hand (apparently wouldn't charge). When I received it, I cleaned out the USB port (little bit of fluff) and plugged it into the charger... no light (expected).. I left it on and shortly after, a solid red light appeared..
After a little while on charge, the phone turned itself on but stayed on the 'HTC' splash screen and went no further. I tried powering it off completely so it would charge without draining battery or slowing the charge because the phone was on.. but every-time I tried turning it off (either holding Power button for several seconds until screen went black... or holding Vol Down + Power button for 10sec as some suggested) the phone would just reboot back to the HTC logo splash screen and stay there.
Eventually I got the screen off (not sure how) and continued to charge, then it came back on again... :/
I tried to boot into the 'Bootloader' to Factory Reset etc.. but I am unable to do so. Every-time I try, the phone would just reset back to the HTC screen.. even if I kept the Vol Down + Power button held down, the phone would just loop to that HTC screen...
As I type this, the phone is sitting, plugged in, Red LED Light Solid lit but phone on (stuck on HTC screen)... just wondering if anyone has any tips ?
Is it possible to reset the phone via ADB if I can't get into the Bootloader ?
Thanks in advance..
UPDATE: Somehow I managed to boot into the Bootloader, and by the looks of it, the previous owner rooted the phone as it have CWM v5.8.4.0 installed. Wiping Cashe, data, factory reset, Dalvick cache etc.. still no change, sits on the HTC splash screen.
i did notice in the Bootloader though, it said the battery was too low to flash .. so I guess I have to leave it on charge for longer to try flash the phone again (maybe previous owner borked the ROM installation or something?)... unless is there anything else I can do? Maybe with ADB ?
Mods, can you please delete this thread.
Sorry for any inconvenience.

i need help... htc 10 in ftm and....

My HTC 10 worked fine until about 5 months ago I went to go use it why mY u11 was being repaired and it wouldn't turn on just kept looping on HTC screen. So I tried to go to recovery (twrp) but when I got to the bootloader my vol up wouldn't do anything my vol down made it move up and my power button made it move up. Power would not let me select anything. So I tried to hard reset it, I tried to go to recovery via buttons and etc. But each time it sent me to ftm. Now in this screen all my buttons worked as they should. And I was able to select reboot to bootloader and it went black and then back to ftm. I selected reboot and it went to HTC screen then to ftm. I tried contacting HTC and they were no help at all. Also I can't even power off the phone unless I unplug the charger....
