[Q] SOLVED!!! HELP! Screen completely black - Nexus 5 Q&A, Help & Troubleshooting

Hello,
I own a Nexus 5 (rooted, CyanogenMod11-M10, ClockWork recovery).
I had found a boot animation that I liked. I tested it but the images where smaller (768x1280), they had a black border around them which I did not like, so I decided to resize them to 1080x1920 also taking care to modify desc.txt with the new size.
But, upon reboot the screen went first crazy for a split second and then went completely black...
I cannot do anything now, I tried to access the phone with ADB but it tells me that I have to answer the onscreen question... I cannot even see the screen anymore
Is there anything I can do short of popping the back and disconnecting the battery?
Thanks
M
--- EDIT UPDATE
I tried Volume up (OR Volume down) + Power to reboot, it did reboot but the same problem appeared, then I tried Vol up AND Vol down + Power and it looked like the phone powered down (I could not see anymore the faint backlit screen)... Then I tried Vol up AND Vol down + Power to reboot in recovery but it does NOTHING... only the Power button alone works but it boots again normally and then again the same problem appears.
--- EDIT UPDATE SOLVED!!!!!!!
It just needed to rest apparently...
As I said I've powered it off by holding down volup, voldown and power... nothing was working: I could not boot into reveory and even the battery icon was not showing up, but after 15 minutes I've tried to reconnect the USB cable and this time the battery icon showed up... At this point I knew could reboot into recovery, so I did :laugh: then I have mounted /system and with ADB I've opened a shell so that I could delete the damned bootanimation.zip file... after that the phone rebooted OK (minus that glorious boot animation)
Yet, if someone has any idea why it had to wait off few minutes, please, add to this conversation.

[Q] Phone continues to reboot, need help

Alright so here's the issue. I was about to flash the latest CM using ClockworkMod, before it restarted it asked for superuser permissions which I had already granted before which seemed odd to me. I set down my phone after this to let it do its thing after this and when I picked it back up it was off and wouldn't come back to life. It's bricked.
When I try to power it on, it shows the Samsung logo and then goes black and then nothing. If I hold down the vol+, power and home to get to recovery it will show the Samsung Galaxy S3 logo then goes black, then shows the samsung logo again, then goes black and stays there. If I do vol-, power and home, it asks to press vol+ or vol-, so I press vol+ to get to Odin. It shows the Odin screen for about 5 seconds and then it goes black and stays black.
So basically, I can't boot, get to recovery, or get to odin long enough to actually use it. Any help is appreciated, thanks.
Sounds like it is time for a replacement. I had a Thunderbolt that did the same thing and couldn't fix it because the phone will not stay on long enough to do anything.

[Q] After System Restore - TF101 Keeps Booting Over and Over Again

Hello All!
My brother gave me his Asus Transformer TF101 to sell but it was heavily modified so I set about putting it back into factory state.
He had TWRP installed so I booted into that (recovery mode, volume down + power, etc.) and proceeded to do a restore. I selected the restore point and clicked "go." Everything seemed to work but now my TF never gets beyond the boot screen (the screen that says "ASUS, Inspiring Innovation..." and has the spinning circle). Obviously something went wrong with the restore and I can deal with that, however, I have a BIGGER PROBLEM now.
I cannot power down my TF. When I press and hold the power button it shuts down (the screen goes black) but then it starts right back up again. I have tried to hold the power button down for 3 seconds, 5 seconds, 10 seconds, 30 seconds, etc. but it always reboots.
Can someone please let me know how I can stop my TF from rebooting over and over again?
Thank you,
Jan
P.S. The main reason why I am needing to power down is I am trying to boot into APX mode so that I can use Easy Flasher.
try vol - and power more than 15secondes. Until you get 2 icons (1 for reset 1 for boot android)

Click to expand...
Click to collapse
When the tf turns itself off just start holding volume-up, eventually the screen will stay blank and you are in APX mode, I've had this issue a few times, just hold volume up and it will eventually boot into apx.
Also try volup and power to hard reset then it will turn on again automatically, be sure to keep holding volume up, apx will eventually come on.

[Q] Moto G xt1033

Sorry, i am really new to this site, and never had a problem like this with a previous phone.
I get home from the grocery store and my phone is off, so it seems, plugged in it, got the M to pop up do the little world thing, then the screen goes to black,
i leave it to charge a little while, come back, and everthing on my phone is working , except for the actual display{now i know its not the display or screen because when i boot it there are no problems with the boot/restart} and if i touch around the screen it lightly vibrates, weird,
i put it to boot menu and my first time trying a normal restart nothing, so i go to motorolas website to get an application to back up my data or something get the motorola device manager and its useless, all it does is tell me my drivers are up to date, look around some more for an easy backup program can't find any except one that won't connect because i can't see where to press ok on the screen
just ended up copy pasting over all 5 gigs of hardrive space
i try to do factory reset, but if i click factory on the boot menu it just restarts it, if i go into recovery it pops up the picture of the opened android robot, and says no command, i have tried pressing volume up for 15 seconds, and then taping the power button to no avail,
interestingly enough once i managed to get the screen on for the phone then it faded to black like a screen saver never to come back.
Anyone know what i can do to unbrick the phone?a program that i can go in and restore it back to factory settings?
i recently updated to 5.0 maybe on friday, haven't had problems, or dropped phone since then
just extremely frustrating,
Recovery key combination was changed after lollipop. Press and hold power button for few seconds and then tap vol up (when you see android robot and no command)
Sent from my XT1033 using XDA Free mobile app
U can flash stock firmware also from your pc..press vol down + power button for fastbootmod then press vol down and then vol up and power button for recovery mod

S7 won't boot, blue LED always on.

Just some minutes ago my S7 froze because of Focus Gallery App. I don't exactly know what it did but the phone did not respond any more.
So pressing the power button did not bring back the phone either. After searching for a bit I found a way to simulate a bettery disconnect by pressing Volume Down + Power Button.
The Phone came back up and displayed the initial boot logo. Also the blue LED is on. But nothing happens from here on. I do not come to the "Samsung" boot animation and the phone simply
does nothing. Retriying Volume Down + Power Button doesn't seem to help too. I tryed all button combinations but nothing brings the phone back.
I also cannot enter the recovery menu. So no chance to reset to default settings.
I am running a stock Android on the phone. Nothing was done by me. No custom ROM, no root, just plain Samsung Android.
Is there sill something I can do?
Edit: I just got into whats seems to be ODIN Mode??? Can I do something from here?
Oddly this happened to me last night although I may have inadvertently done it. But the only way I was able to get my phone functioning again was reflashing the OS to the phone.
How did you manage to get the phone into Odin mode? I'm having the same issue with the phone being totally unresponsive but the blue LED on.
if you can reboot your phone with the VOL Down/Power, when the screen goes black, quickly press and hold VOL Up, Home and Power. it should enter recovery. or hold Vol down, Home and Power to enter the download screen.
I have the S7 Edge (rooted, custom ROM) and it's running fine. My girlfriend's regular S7 is having the same issue though.
When she plugged it in to charge last night, she checked it a few minutes later at which point the phone had (started to) reboot. The blue notification LED was on and the screen had frozen at the 'SA' from the 'SAMSUNG' startup logo. Forced a reboot with down+power, resulting in just the blue LED (no logo this time). Phone was unresponsive (couldn't force a reboot again) so left the battery to drain overnight. The phone is completely dead today even after charging - no LED, no boot, no anything.
I'm not sure if she had the phone scheduled to perform an update overnight and it froze halfway through, but that would be my first guess. So far, no fix.

Honor 8 boot loop - no fastboot no erecovery no dload - is it dead?

I think my phone has gone forever, but I'd like to check here if someone can save it.
I've been using this phone for 3 years, no changes besides OTA updates. Suddenly, screen froze and I held POWER button until it turned off. Then it rebooted and showed honor powered by android in blue background. It shows only that screen for a minute or so and then reboot again. If I hold POWER button, it'll reboot again (it won't turn off). The only combination of keys that produces different result is combo of VOL UP + VOL DOWN + POWER, which will turn screen black, then vibrate and then turn off (if I release keys before it vibrates, it'll start over).
I tried to put dload\UPDATE.APP in sdcard and nothing happened. I also tried all combinations described in a post I found in modaco forum (www[dot]modaco[dot]com/forums/topic/377629-honor-8-button-combinations-clarified/) and I don't get any other result besides what I described before.
Is there any way to fix it??
Did you try to press power and vol- ? When it boot, release power and keep your finger on vol- while connecting to a computer using USB. Normally, you should access to fastboot
EDIT: Oh sorry, in hurry I have not pay attention to the website you quote :'(
