Nexus 5 will not recover - Nexus 5 Q&A, Help & Troubleshooting

Earlier today my phone (nexus 5) stopped working on me. My phone is not rooted or anything. I was able to get into the recovery screen by pressing the power button and volume key down and have been trying to restart the phone this way but it is taking forever. It's been hours and nothing has happened. The 4 colored circles have been going on forever. I didn't have USB debugging on. My laptop recognizes that a nexus 5 is connected but it says the drivers are not installed. I installed the usb drivers from google but it has not helped. I'm a noob and don't know what to do please help

[Q] Phone works but screen is black?

So today, I was making a long checklist using the Google Keep app on my Nexus 5 when the screen suddenly went black. Nothing I did could make it go back to normal. Holding the power button brought up the "Power off" option, but even after I pressed it and rebooted, the problem persisted. I later tried to start the phone in recovery mode and clear the cache, but neither was able to solve the problem. I know the phone itself is working functionally because I got an LED notification light. Does anyone know how I can fix this?

Black Screen, Green Power LED, APX with USB connect to PC?

So, I am in new territory here. My tf300t suddenly stopped working. I had previous unlocked the tablet (years back) but never installed a custom rom. It was working fine for a few years and I factory wiped along the way a couple times. So a couple months ago I did a factory reset again and it seemed fine for a few weeks. Yesterday I picked it up and I can't get it to turn on. Here are the symptoms:
It will charge and shows a green LED
Can only get a Black screen and will not boot, no ASUS screen or anything
I tried holding power for 30 seconds
I tried holding power and volume down for 30 seconds
I tried the tiny reset hole with a paper clip and the same with power button
When I connect to my computer with a USB it shows up as APX on Windows 10
Is it just dead now? Bricked? Thanks for any insight! Seems strange but maybe it decided to die.

I have no idea what happened to your tablet. If I were in your boots, I would install "Minimal ADB & Fastboot" from here: http://freeandroidroot.com/download-minimal-adb-and-fastboot-all-versions/. Then please check whether the USB driver are installed or not. If not get them here: https://androidmtk.com/download-asus-usb-drivers.
Connect your tablet via USB with your PC. The devise manager should show "Android Phone" => ASUS Composite ADB Interface and "Portable Devices" => TF300
After that seen you have access via ADB to your tablet. Then please flash the latest Asus firmware update to get your tablet on a clean stock rom. For assistance please search the forum. Good luck!

Sony Xperia X10 Mini Pro (SK17i) stuck in Boot Loop, can't connect to PC

Hi,
I hope this is the right place for my help request.
I don't have any experience with rooting, unlocking or any of that stuff, but I have a bit of background in Android app development.
So I have been using this Sony Xperia X10 Mini Pro (SK17i) for years, because it is small and has a hardware keyboard.
It has Android 4 installed with no modifications whatsoever.
A few days ago the battery went completly dry (0%) and the phone turned itself off. If I remember correctly I was using it to play music via bluetooth when it turned off.
After that (and a bit of charging plugged into the wall) I tried to turn it on again, but ever since it is stuck in this boot loop where it turns on, shows the basic white on black Sony logo for a few seconds, shows the animated Xperia logo for maybe a minute or so and then reboots!
I have no idea what actually caused this or how to fix it. I didn't use the phone for any modding/flashing/unlocking or stuff like that ever.
I can't even properly connect it to my PC (Windows 7 64-bit) anymore. The timeframe where it is turned on (during the Xperia logo) doesn't seem to be long enough for the drivers or PC Companion software to detect it.
Taking out the battery or SD card didn't change anything about the rebooting behavior.
The only thing I could do (after some research, I really have no idea about this stuff) was put it into this "fastboot" mode by holding volume+ down while plugging into the PC. Then front LED went blue and I could see the device listed after executing "fastboot devices".
But I don't seem to be able to do anything else with fastboot (like flashing a CWM recovery image, which I have no knowledge of either...) because the device is not rooted.
I have the Android SDK / Android Studio installed if that helps.
So any ideas about this situation?
I really want to keep using this phone, and I also have some important personal data on it that I don't want to lose.
Any help would be greatly apreciated!
Thank you.
Sorry for the double post!
Ok, so I have just read about this "recovery mode" thing, but I am unable to enter it!
According to most guides (like this: http://www.hardreset.info/devices/sony-ericsson/sony-ericsson-xperia-mini-pro-sk17i/recovery-mode/ ) I should turn the phone completly off, then hold volume down (-) and power on simultaneously until the device enters recovery mode. But it doesn't! It just keeps booting normally!
What should I do?
Thanks.

a few years later but I had to bring back to life my old Mini Pro.
To boot in Recovery Mode I've had to remove the SD card and it worked with Volume Down+Power key. With the card inserted it didn't work.
I LOVE this little keyboard!
Regards.

[SM-G925F] Hard Bricked, not turning on.

Hello guys,
My Samsung Galaxy S6 Edge (SM-G925F) has been sitting in the corner for a while. I've flashing it so Custom ROM (don't remember to which) and it got bricked. I've tried all possible ways to turn it on (Volume DOWN + Home + Power), but nothing helps. I can't turn on the Recovery Mode and Download Mode. I connected it to my PC, it recognizes it but instantly disconnects from it. When I hold POWER button, computer it recognizes it, when releasing the POWER button, it disconnects. When I open Device Manager on computer, it recognizes it as a Exynos7240. I tried to install various drivers but no-one seems to be working. The phone can't be detected by Odin, Multidownloader, Smart Switch and other apps.
If anyone knows the solution how to fix it, that might be really helpful.
Computer is using Windows 10 (64-bit).

Tablet appears to be dead

Hi
I had this tablet for about two years, ran amazon Fire toolbox on it and everything was fine.
Couple of days ago it turned off, I think the battery level was around 15%. I was not able to turn it back on.
I decided to charge it overnight. Next morning I tried to turn it on but it stuck on Amazon logo.
I tried to do Power + Volume and was able to see the menu, attempted to do restart, then factory reset - and had this bunch of errors. Then I did the power down from the menu, and after that it doesn't turn on even to recovery any more, the screen is black, no logo, no backlight.
When I connect it to computer (the same I ran amazon fire toolbox on) there is an unknown device, but that's it, adb and fastboot don't see any devices.
Update: another windows machine recognized it as a Mediatek USB port and was able to install drivers.
When connected, it appears to be in a loop - Mediatek USB port device appears and in several seconds dissappears, in cycle.
Any help will be highly appreciated!
Thank you!

Your eMMC probably died (notice the input-output errors), try to use amonet. If the script reports "read error" then nothing can be done.
