[Q] Phone is ON and stuck at blank (black) screen - Android Q&A, Help & Troubleshooting

Hello guys.
Today I decided to flash a custom ROM on my HTC One M8, I've installed TWRP recovery, and wanted to wipe my phone before I install the ROM. I was dumb enough to delete the ROM .zip file itself, and then I decided to push it with ADB and my PC USB Cable through "push myrom.zip /sdcard" command. Everything went ok, file was successfully pushed, but after that TWRP Recovery got stuck at black screen (LED is ON), phone power off button didn't work, nor power off+volume down did not.
Then I tried to "adb reboot recovery" but the black screen didn't go, instead of that I now have "adb devices" telling me the "device is offline". :crying:
So I am stuck at working black colored screen with LED on, I can't power off the phone, and ADB says that usb is offline now.
Any help please? How do I power down my phone to reboot it? If I will wait my phone battery to die itself to charge it and turn on my phone, it will take ages?
P.S. Forgot to mention, the phone has been in this blank screen condition for about 2 hours so far, and the battery (or proccessor?) seem to be working pretty hard, because phone's back panel is hot just like when I am playing a heavy graphics-intense 3D game on it. So phone is doing something, but not responding to buttons. I hope the battery will drain faster this way, so the phone will power off and I will be able to charge it and reboot at last?

The problem has been resolved!
The problem has been resolved! :victory:
At last, after being in that "rather dead than alive" condition for 6+ hours, my HTC One M8 battery got fully drained and the phone powered down.
I plugged it in to charge and it's alive again! :good:
P.S. If someone else will have this trouble in the future: on another forum people suggested me to press&hold all the buttons simultaneously on the phone (there are 3 of them: power button, volume up and volume down) - the phone should reboot after that.
P.S.S. Guys, if someone has a tech-related blog or a website, you could do an article about this problem and it's solution, because I haven't found anything about this on the Web, and figured out to wait for battery to drain just with my own logic. Anyway, such an article would be helpful for the Android community.

[Q] Dead battery = boot to recovery with no video

This is something odd I haven't experienced with any Android device until now.
Whenever my Rezound battery is depleted to the point where the phone shuts down, I cannot get the device to boot back up again without ADB.
While it's powered off in this state and plugged into charger, it exhibits no charge LED or any other type of activity.
After pressing the power button, it appears to do nothing whatsoever.
If plugged into my laptop USB, the OS detects the device and loads the Debug mode drivers. ADB DEVICES shows the device as being in Recovery, and the device is still completely dark, no video, no backlight, no button lights.
At this point I can ADB SHELL and issue commands, but it can take up to a dozen REBOOT commands (although sometimes on the first or second try) to get the device to do anything other than reboot directly back to dark-screen recovery. I just keep running REBOOT until finally the white/green HTC image appears and the phone boots normally as if nothing was wrong.
Once booted, it behaves perfectly for as long as the battery doesn't die. I can reboot, HBOOT, power off and on, do a Clockwork backup... But, if i let the battery die, I have to ADB REBOOT until it decides to come back to life.
What do you think. Hardware or software issue? Try RUU?
Thanks!
there's definietley a huge problem wtih this phone. i had a guy bring in a phone that died overnight and the same thing happend...he'd plug it into the wall, for 5 seconds it would show orange charging LED, then just shut off..phone wouldn't power on, either. he had it plugged in charging for 3 hours though, and the phone was still dead.
when i switched batteries, teh phone would not go past the white HTC screen. it was just dead. we had to get him a replacement. i'm seriously afraid to shut off my phone now or even let it die. sigh.
Oh yea, mine does the not booting past white HTC screen occasionally between REBOOTs as well. I am disappointed with HTC now, my original AMOLED Incredible was totally rock solid for the 2 years I carried it along 40+ airplane rides to 11 different states. This Rezound craps the bed if you give it a dirty look
Everyone should take a look at this thread in the Vivid forum. People were havin problems with their phone booting into CWM when the battery was dead, me included. Our CWM was updated to support charging and now all is fine. Might be worth looking into.

Weird, just let my battery die before reading this thread, didn't experience this..
but def not going to let it die again!

[SOLVED] black screen, flashing red light

So hey guys, I was just playing a game this afternoon when my phone suddenly went black (while being in the charger).
Now the red notification light is flashing and the keys at the bottom are also lighted. The keys do give a vibrating feedback, but my screen keeps black.
Holding power-button results in flashing keys, but when i release the power button nothing is changed to the previous described situation..
Any idea's what to do..?
------------------------------------------------
Update:
It rebooted again! After lots of tries and wondering if i should take it back to the dealer i found the solution!
What i did was:
- Press and hold volume down button, add and hold the power button.
- Wait till the capacitive keys start flashing and then release the volume down button, but keep holding the volume button!
- Now my phone boots normally.
Not sure if this normally makes you boot into recovery, but it made me able to power my device back on!
are you completely on stock or did u flash any rom/kernel?
there are two things i can think about:
you maybe flashed a oced kernel, set it to performance (locked it at 1700ghz quad maybe) and put it on the charger while gaming. if you did that i can imagine that your device just overheated but you should have realized that by holding it in your hands while gaming.
another option is that it's just stuck.
do you have debugging mode enabled? then try if adb can find your device and maybe even kill processes or reboot
other thougt: as long as you don't have twrp as recovery let the battery run down and just plug it on the cherger over night as long as the hardware is allright it should turn on again

Sorry, but what is a oced kernel..? It is possible that it overheated, but i have put it down for 3/4 hours now and still nothing changed..
I have it enabled, but my computer doesn't find my phone anymore so i cant use adb..
And 3rd i do have twrp as recovery, but I don't really get your poin on that. I have to run the battery down, but still put in on the charger over night?
edit: It just went out of battery because the red light stop flashing. Then i put it on a charger and it started flashing again..
now what..
Re: [Q] black screen, flashing red light
On my last HTC device. Flashing red light meant you killed your battery.

You shouldn't have let your battery die when you have TWRP because the recovery doesn't allow you to charge your phone when its dead and that is a known error. Might be time for you to get a batter replacement my friend.
Re: [Q] black screen, flashing red light
something similar happened to me last night only i wasn't gaming and my battery was dead. i plugged it in and turned it on and my system ui stopped. so I reboot to fix but screen went black and lights went off (except for red led) but didn't come back on. tried to turn on with power button but nothing happened. i held power but for longer and got flashing buttons and red led went out. tried again and same but led started flashing.. another try and just got flashing buttons.. gave it a couple minutes and tried again and it came on. battery was @ 0 after boot. i also have twrp

[Q] [HELP] HTC Desire X won't turn on, but will charge

Guys I really need help with this,
Last night (03/06/2013) my HTC Desire X was connected to my laptop (Lenovo Ideapad Z570) and was connected to HTC Sync Manager, and I was trying to sync my contacts, because I didn't want to loose them. I had previously backed up my photos and music, and just before I went to the Contacts tab, the phone screen and touch buttons went off, but the little red LED at the top stayed on, and didn't flash, and I think the phone turned off, but it showed no screen with HTC on it, it just went straight off. It wasn't the battery loosing charge because it was plugged in, was charging at the time and was over 50% charged before I plugged it in. When I plug it into either AC power or USB charger, the little red LED comes on, but nothing else happens. So I tried to take out the battery for around 5 mins and then put it back in and leave it for about 5 mins, but still nothing. I then tried to hold down the Power button for around 30 secs and it didn't work. Then I tried to hold down Vol- and Power for around 6-10 secs, and still nothing. I then tried to leave it on charge over night and see what that would do, but it did nothing. When I leave it on charge over night it charges fully, and the red LED turns green, but when I plugged it in, it just went red and stayed red. I got the phone around January, February, so it's new enough. I got it from the Carphone Warehouse. It was new when I got it. I haven't rooted it at all, haven't loaded any ROMs onto it or anything. I haven't tried rooting it or anything, and haven't tried any ADB stuff.I haven't downloaded anything from a website I can't trust. I was going to root my device, and that's why I was backing up, but I had already backed up my music and photos from before, but I wanted to make sure so I did it again. I don't know if it's bricked or not, but I've a feeling it is, and I don't know what it is that I did to brick it. I really need the contacts off it though, and I have ADB set up from before when I was just about to root it after I backed everything up. I now have the SIM and SD out of the phone in case it damages them, and I have the phone connected to the laptop with the battery out. I heard that you can take data from a phone using ADB, so when I set up everything, everything was ready and the red light was on on the phone, but the ADB couldn't find any devices. I am running ADB from cmd, and run cmd in administrator mode. I want to try to take all the data from my phone, and then hard reset it using ADB, because the hardware buttons won't come on on the phone.
Thank you very much,
Robbie
If there is not anything on the screen and you can't to go to recovery! Remove your battery for 1-5 minutes then shove in, then press volume- and power buttons! If there is nothing on the screen go to service, because you have or bricked phone or die lcd!

[Q] Motorola Razr XT910 Stuck on M logo, does not have access to factory cable

Here's the story: I'll try to make it as short as possible (I'll also put on a TL;DR at the end)
My phone is rooted, flashed to Cyanogenmod 11 nightly build, no problems when I flashed these guys.
I installed Lucky Patcher to patch an app, put some files on my SD card (bunch of PSX games)
just put it out there if that changed anything
My battery was low at that time and I did not expect that if I let it shut down by itself, I could still open it just like I do in the past.
Phone totally has no charge on my battery 0%. I plugged in my charger, the phone opens up but it only opens the M logo with Dual core technology (not the pulsing M). Tried to charge it overnight, still stuck on dual core screen, tried resetting using Power + Volume Down, and also going through where AP fastboot, BP Tools was, If I choose any of them (except for fastboot) it would redirect me again to the dual core logo.
sometimes I get lucky if I choose BP tools and goes to TWRP recovery (safestrap installed), tried to boot there and still no luck.
also tried unplugging charger while on the selection of AP fastboot and just shutdowns my phone. also one time it redirects me to one with a battery icon and a question mark.
I also don't have access to factory cable, can't buy one because it's not available in here in the Philippines, tried making one but I reaally suck at soldering, also when I opened up the wires, it only shows up 3 wires, red, green, and white, the other one I opened was only red and black.
TL;DR : Phone battery is dead, when plugged in charger, Motorola Razr Stuck on M logo (with Dual core technology). I also don't have access to factory cable, can't buy one because it's not available in here in the Philippines. Also there's no more Motorola stores that I can get a fix (I think they got bankrupt :silly
I really love this phone and I would really appreciate if I could get a quick fix
Sad, it seems that the questions here seldomly get answered, hope the experts go online soon

It's OK don't worry. Just charge the phone for about two hours, unplug the carger and faster reset the phone wiht power + volume up + volume down. This way you can boot to safestrap. You will see that battery is on 0%, so plug the phone in the charger and wait. Until you are in safestrap the phone will charge. The battery needs at least 5% to boot the OS, I myself prefer to reach 20 even 30 percent. Then on safestrap's homescreen press reboot, then system and after the phone reboots wait or press search when safestrap's splash screen shows and the OS will load.

It Worked! Thank you so much for your help. The only problem I have now is that everytime I get my battery low, it doesn't go on charge mode when turned off. is there a fix in that? But overall, the trick that you thought me worked, and I'm using that trick when my battery gets low.
It seems hard to get a fix for this issue, so I used the app "Tablet Auto Power Off ★ root" and set the auto shut down when the battery reach 5%. It gives me enough power to restart the phone when I'm ready to charge it.

Old Z2 Tablet SGP512 Given All It's Got?

As the title suggests I have an old Z2 tablet that has been an absolute work horse for many years. I was using it one night and the Android OS prompted me that the device hadn't been rebooted in 28 days. So after I was done using it for the night I rebooted it. Only, it didn't reboot it just stayed off. I tinkered with it for a while and got it to show the Sony logo but then it just went dark again. The device is rooted and I have TWRP on it. So when I got it to turn on again I booted it into the TWRP recovery. I proceeded to clear the cache and also attempted to make a current backup. However, the backup would fail after running for several minutes. I decided to try backing up to an external OTG USB drive but the device needed to be rebooted to detect that the OTG USB drive was attached. So from TWRP I selected "reboot recovery".
Unfortunately that was the last time it worked. The screen will not come at all. When I hold volume+ and power it vibrates 3 times but still doesn't boot. I plugged it into the charger even though the battery charge last showed at 85%, but with the cable connected the charge light doesn't even come on. I tried plugging it into my computer but it doesn't detect the device has been connects and adb devices doesn't show anything in the list.
I read on a forum to try drying it out with a hair dryer and while the device hasn't ever gotten wet it has been humid here so I figured what the heck. Unfortunately that also hasn't resolved the issue.
Pretty much everything I've tried hasn't worked. Even the red reset button under the top panel just causes it to vibrate 3 times.
The device has been in this state for a week now. I was hoping maybe the battery would die and then I could recharge it, but since it still vibrates 3 times I'm guessing the battery still has a charge.
One thought I had is that maybe the internal storage is either dead or corrupted.
At this point I'm wondering if the device is a lost cause and I should just let it rest in peace or if there's any other solution. Even if there was a way to factory reset it from it's current state that would be better than having it be a paper weight.
Any suggestions beyond what I've already tried would be greatly appreciated. And, yes, I may look into seeing if I can get it serviced however there's definitely no warranty and I don't really want to poor money into it since it's probably time for an upgrade anyway.
Why is my phone vibrating 3 times and won't turn on? - Sony Xperia Z5
When I try to turn my phone on it just vibrates 3 times and does nothing after that, just wondering what the problem could be?? - Sony Xperia Z5

The device vibrated 3 times, that's good, then it is off.
"Sony writes: This is how you force the device to turn off:
Press and hold the power button and the volume (+) button simultaneously until the device vibrates three times."
Did you try to put the device into flash mode after that? I think only a complete flash will bring the device back to life.
