[Q] My Screen Is Stuck On Black! :( - T-Mobile HTC One (M7)

Hey Team!
I've been rooting and tinkering with android phones since the HTC Dream days. Normally, most troubleshoots I can overcome on my own fairly routinely over the years. I kind of feel like I've met my match on this one and I could REALLY use you guys' help!
Here's the story:
So my phone, of course, is the T-Mobile HTC One. What I've done so far? Unlocked the Bootloader. Added a CWM custom recovery. Currently using a 1.29....16 OTA clone deodexed Rom created by Team Nocturnal. I'm using a Faux123 Kernel and have it overclocked to 1.9 GHz with all of his suggested UV settings and Intellidemand Governor chosen. I have the Xposed Framwork installed as well. I've had all of this running smoothly together for weeks with not one random reboot or lockup. The phone has literally been flawless. Until this.....
So, i'm listening to music with headphones plugged in for my Spotify app and relaxing. About 10 minutes into the music session, the music stops. I look down and the app seems frozen. I pick up the phone and turn the screen on. As I swipe the screen to unlock, the phone freezes. I turn the screen off by pressing the power button. From this point on, the screen will not turn back on at all!!
What I've tried:
1) The usual hard reset via power button and volume down. Even power button by itself. The capacitive buttons just keep blinking, but the device never reboots at all.
2) I've tried plugging the device to a computer. The usb connection responds because the computer makes a sound. When I look at the device manager, it does show that it detects the M7 device to be connected. However, when trying to use any ADB commands, it simply states the device is not found (running Windows 8, btw).
3) Freaked out for about 10 minutes before regaining my composure and thinking of one last thing. Only thing I can think left to do is pull the battery. Of course this isn't possible with the HTC One, so my only comparative option would be to let the battery drain completely. The irony is that I boast so much about my phone's battery life, so I know that I'll be waiting 2-3 days for this to happen before I can hope for resolution after.
I've tried to be as specific as possible here guys. I'm far from an expert, but I've owned 4 or 5 android phones since 2008 and have never bricked one. If anyone knows anyway to bring my phone back from this RANDOM sleep of death, please let me know so.
Forever Grateful!

put it under a bright light while holding power or power+volume down

When home and back button blink, do they keep blinking and did you try holding the power button. This happen to me the home and back button kept blinking and the display stayed black, so I kept holding the power button, and the screen turned on... so, not sure if you already tried this anyway, good luck

Thanks for your help everyone! The bright light technique worked!!!

I had the same problem and letting mine completey die worked tried the brightlight and didn't work checked two days later it died put on charger and bam right on

i am having the same problem, its a pain in the ass to get a light on the sensors, could it be that its happening because i also use a charger for a different android phone? had a old lg mytouch 4g charger. maybe i should let the battery drain completely. i want a real solution instead of having the phone screen shut off and stay off on me.

[Q] Unable to boot my HTC Amaze 4G

Hello all, I have a HTC Amaze 4G phone and I recently unlocked the bootloader and installed CWM 5.0.2.6 Recoveries and the Faux 0.0.8 Kernel. Then I also installed the Energy Sense ROM 3.0 and got it installed and everything was working great and dandy. I was able to use my phone! Cool!
But here is the problem I'm having. I turned it off for the night and plugged it in to charge. Woke up this morning to try powering it on it wont power on. Here are the problems I'm having:
When I push the power button I can see that there is a -very- faint white line that I can move up and down with the vol. up and vol. down keys. Along with pushing the home key which moves it as well. (They also respond by vibrating upon press) The screen is so dark I can't see what it is saying but I know that at least it's responsive in some way.
I've tried removing the battery and putting the battery back in, plugging in the phone (Which sometimes I get a blinking orange light other times it will stay a solid orange)
What went wrong? Why will doesn't my phone boot correctly? And why does it boot into the recovery menu with the brightness turned virtually down to 0? Any help would be awesome! Thanks so much in advance.

[Q] HTC Amaze bricked?

Hello XDA,
First of all, thanks ahead of time for helping me out.
My HTC Amaze 4G is rooted with the regular Stock ROM - in other words I only used my root to change the processor speeds (usually make the CPU slower to increase battery life).
I was watching a video yesterday using MX Video Player which was decoding the video in Hardware mode. Other details about the video is that the video format was h.264.
I was watching the video, and then all of a sudden, my phone freezes up, and nothing works at all. I am unable to sleep the screen, none of the capacitive buttons or the volume buttons work, and holding down the power button is also useless. I waited a few minutes, occasionally trying to turn it off by holding down on the power button. After nothing happened for many minutes, I removed the battery (which turned it off), and then reinserted it.
Because Android has hideous boot times when not turned off properly, I decided not to wait, and instead went to bed. This morning I try and turn the phone on, and it wont budge. I try a number of things to get it on, such as removing the battery and the SIM card, and many other combination of tricks. Once again, nothing worked. I should note that when plugging the charger into the phone, the orange light does appear occasionally, which means that sometimes it will show up, and sometimes it wont. Also sometimes when I plug the charger in, the orange light flashes on and off, sort of like a notification, for about 10 seconds.
It would be awesome if someone could help me out, as the carrier I'm with sucks at repairing/replacing phones because they are super cheap and annoying (Mobilicity).
Thanks,
Robert

your battery most likely went bad because you didnt pull it when the device locked up... so you may need a new battery if you ever want to boot again.
next time if your phone locks up, pull the battery instead of letting it go.
Your battery is dead. You should've booted it right back up after you pulled the battery. One of the issues with root and the wrong recovery is not being able to charge the phone when the phone is off. Get an external battery charger or find someone with the same phone or battery and start it up.
Now...please check the other threads requarding Amaze being bricked or unable to power on.

Thanks for the quick response everyone. Can anyone point me to where I can buy a new battery?

Thanks for the quick response. When you say pull it, what is it?
Thanks!
Pull the battery out, try ebay.
Over 10000!!! You bet I am.
Buy a charger that allows you to charge the battery outside/ independent of the phone. Ebay has those for 5 bucks? Each

I had this exact problem.
If you rooted your phone a while ago you installed a recovery that did not support off-charging. So when you plug your phone in, if you look VERY closely at your phone, you will notice a green menu that you should be able to move up and down with the arrow keys.
The only way to fix this is to do one of two things.
1) The method I used: (NOT RECOMMENDED AT ALL, EXTREMELY DANGEROUS)
Take the battery out of your phone, get a 9-volt battery, and two wires.
tap the wires to the respective (+ and - leads) of the battery a couple times.
KEEP IN MIND, YOU ARE DEALING WITH A LITHIUM-ION BATTERY, IF YOU OVERCHARGE OR MISCHARGE A BATTERY. IT WILL EXPLODE, POWERFULLY.
2) Buy a new battery and install 4EXT AS SOON AS POSSIBLE.

[Q] please help!

Last night i fell asleep and my phone died all the way, and now when i plug it in all i get is a lg logo then it goes away and then a dark lit up screen. ive let it charge for awhile now and i still get nothing, i cant get into cwm either.. the phone is unlocked and rooted and im running the base rom. Any help would be greatly appreciated.
Happened to me... leave it on the charger at least 3 hours and check it. The battery completely drains when you unplug the charger if you charged with the phone off. gl
Edit: If it still won't work, turn phone on and plug in charger.

This happened to me too. I completely drained the battery and it kept going into a loop (black screen, LG logo, battery screen). I left it plugged in and off and let it boot up.
FYI
This has happened to several people. I have confirmed through testing, even exchanging my phone 2 days ago that this is an issue created when unlocking the bootloader. Rooting does not cause it. Once the bootloader is unlocked, you can not get around this by re-locking the bootloader.
The workaround is simple. Either leave your phone on while it is charging or if you charge with phone off, unplug your charger and hit the power button- you will still see the charge animation running- this is what causes the battery to drain. All you have to do is power up the phone at least to boot then it is ok to turn off. You can confirm it worked by touching the power button again and not see the charge animation. Hope this helps.
Wow thanks so much for the reply and help! I've got it working now and I guess I'll just avoid it by not letting it die lol

well...
If you let it die all the way, its not a big deal. Plug it in, hold down the volume down button and the power button for 15 seconds, then it will work fine.
Threads like this makes this forum so great. Another potential problem to be avoided when using the phone.

I could use some help guys, if this thread isn't too old. I've searched high and low to the answer here and nothing is working. I've tried download mode, fastboot, recovery, reset, holding power down, plugging it in and unplugging it. I've pulled the plate off of the battery, tried LGNPST, drivers, etc. No go on anything.
The phone is still dead, and will not turn on. The best I've gotten is a solid red light after holding the power button for 15-20 seconds. Then after about 3-5 seconds it resumes flashing (alternating between the red light and the key buttons). If I continue holding the power button down it will repeat this, showing solid red and then reverting to flashing.
I can not get the screen to display anything, not even the charging animation, and none of my computers will even recognize the device. I've been messing with it all day and I'm stuck. If anyone can help me, at all, please do. I hate going to Sprint. Anything but that, please.

Help! Can I turn on my HTC One Max without using the power button?

My One max's power button isnt working and my phone died. is there anyway to get it to turn on? I had the bootloader unlocked, cyanogenmod 13 and root.
Backstory: A while back, my volume keys were acting up and my phone would constantly go to low volume like if i was pressing and holding down the volume down button. Next thing you know, the power button isnt responsive and I cant wake my phone. The only way to get it to wake up was by getting a phone call. Sure enough I failed to keep my phone's battery charged and the phone died. I charged it and the battery is at 100% but i cant seem to turn it on. any ideas? thanks, I truely appreciate it. I know im going to have to get a replacement flex cable, but I dont want to wait for shipping to get it turned back on.
From one Moe to another...
My One max has behaved exactly like you described this summer and the last summer. Happens every time I answer a phone call with sweat going down my ears, it gets downright humid here! Usually fixes itself after a few minutes in front of a fan in an airconditioned room. By the end of last summer, I had to get the button strip replaced. Hope I am more careful this summer in order to keep it all in order this time around.
Last summer when I realized the power button was on its way out, I used Sense Toolbox (an Xposed mod) to set my device to wake from volume buttons. Of course that doesn't help if the phone dies from low battery like in your case.
(Edit: I also have a custom setting, I think also applied by Sense Toolbox, that wakes the screen when plugging in the charge cable. But this, too, only works when the device is fully booted and running.)
Maybe someone else can help with an obscure key combination. I dunno, maybe something like holding down the volume down button while plugging the charge cable in?!? Cuz my device (s-off, rooted, twrp, lollipop stock) starts charging in power down state, and I can see the splashscreen transition into the TWRP screen briefly flashing several times as it eventually gets into the charging screen (big green battery with percentage on the screen).
Cheers from Pakistan and Eid Mubarak!

Question Realme GT 5G just turned off - now in bootloop

Hi,
Just few minutes ago my brand new phone just broke on me. I was holding it in my hand, locked screen, like minute later I tried to unlock it to no avail, screen just stayed black. There was a sound when I touched it by the fingerprint sensor, but no light up from behind the screen. I tried holding down power, then power+volume up, phone only vibrated, no reaction on the screen. I've connected it to the charger, and now it seems to be in bootloop - screen is turned off, and every few seconds phone vibrates. I've managed to somehow turn it back on once, phone booted to system, everytthing worked just fine, then I locked screen and it just stayed black, now I can't reproduce that, can't even turn it off, it's just vibrating every so often. Did it really brick in my hand? Software of Hardware? Everything worked just fine, maybe battery was draining a little bit too much for my taste, (15-20%/hour with screen on+lte/wifi) but 120Hz refresh rate+bright setting and AOD turned on 9am-9pm could do that. Do you guys have any suggestions, or I'm expecting trip to the service?
Sorry, but i cannot guess any reason. I am stumped as this bootlooping shouldn't beb happening... Very strange. May be its better to show it to service center guys.
Btw, i had tried this on my previous android phone to shut it down, like a hard shutdown. I had pressed power + volume down + volume up keys together to shut it down completely. Basically by pressing all the 3 keys. If you want to try, you can try it. I have not tried it on my GT, but had used it on Oneplue 2 and Honor View 10.
Hope your issue gets resolved asap...
Okay, I've contacted support via livechat, they told me it's definetly just software glitch, and to resolve this I have to wipe dialer cache (?) and all system settings - I did it, everything worked just fine, but today, again, same thing happened. First time phone just died in my hand, second time it was while listening to music via Pulsar, today I was just sharing wifi as a hotspot, phone randomly broke connection and would not unlock, but still I could tell it was on, because of vibrations and sounds. Not a software glitch after all? If I manage to unlock it I'll just recover it to factory settings, we'll see if that helps, but I don't like the sound of that.
What apps are -you- installing?
Launchers and power management apps are prime suspects...
Otherwise, mobo failure. It may be firmware but how far do you want to take it?
It should run fine out of the box.
Last time I played with launchers was with good old SGS about 5 years ago, only app out of ordinary was AccuBattery to check that SoT drain, but could it make such a damage without root privilages?
