6P unresponsive after enabling power saving mode - Nexus 6P Q&A, Help & Troubleshooting

Had the phone at 2% battery and enabled power saving mode until I could get it to a charger
The only issue is it immediately became unresponsive, finger print scanner didn't work and I could not wake the device to unlock
The low battery LED was still blinking but has since stopped, I've tried holding down the power and power+volume down as well as all three to no avail
I'm unable to also use any adb commands as connecting it to a usb cable will not charge it or allow it to be seen by my computer
Any ideas on what to possibly do?
EDIT: Taped all three buttons down and took a shower, came back and it was on. Really weird

[Q] POWER RESET or UNKNOWN UPLOAD MODE

Anyone having boot problems?
Waiting the case, i have put my tab in his box moving from a place to another, when i took it i saw a green andoid image with the message "POWER RESET or UNKNOWN UPLOAD MODE".
Now it is blocked in this message state. Can't turn off, reboot ...use it...
Anyone know the way to reboot (key combination)? if galaxy tab has a recovery system? or something in order to resolve this problem?
Just to know, no root attempts, only some application normal installed from the market...
hi, i think if you press the power button and leave it pressed, it will reboot.
after the battery charge finished and the recharged all work fine...
i think the "block state" has been caused from the home+volume keys that probably were were pressed in the box..
it would be usefull to know these key-press effects
They are standard android combos. Google is your friend.
I stumbled across this screen while my Samsung SGH-I897 (Captivate) was powered down, hooked up to my PC using the USB cable and the battery was half way charged. I held down both the power and volume up buttons for a few seconds and got to this screen before the unit attempted to boot. It remained there until I held down the same key sequence for about 5-7 seconds. It's now back to a powered off state, still hooked up to my PC via the USB cable, and the display has the standard large battery icon showing it at about 50% charged. Leaving the Captivate idle will continue to charge my phone via USB (abeit slower than having it attached to the power adapter) and the screen shuts itself off. It practically looks like it's fully off or fully dead like this, but it's not.

[Q] My Aquos Crystal appears to be bricked after complete discharge

Hey everyone,
I don't know what happened wrong with my interaction with AQUOS, but the phone appears to be bricked.
Here's what happened.
Bought my phone from Boost, successfully switched carrier to Ting
Have been using the phone for more than a month without any problems at all
Yesterday, I left the phone without charging and it fully discharged
I plugged it to charge and came back to turn it on after a few hours later. This is when I noticed it wouldn't turn on.
I tried a couple things: holding the power button for a long time, and a hard reset (volume down button + power button). But the results were the same.
The screen doesn't turn on. While holding the power button or power + volume button, the only feedback from the phone is a series of prolonged vibrations (~10 seconds) separated by a brief pause (~1 second).
Have anyone experienced this problem?
Any advice/insight into this problem would be greatly appreciated.
I've had similiar issues with tablets where it completely drained and wouldn't charge via USB. At most it'd just give off a single vibrate and then die before even flicking on the screen. Try this, plug a USB cable in for a full 24hours before you hit the power button. Then give it a try. If it pops on to the screen where its charging after that let it get a full charge before fully powering on. Hope this helps and also hope its not due to the switch to ting.
Best of luck
PHONE OFF
This could be due to a bad usb connection. some usb when broke will actually discharge your phone or tablet so try to use a different usb. PLZ POST BACK IF THAT DIDNT WORK I HAVE MORE SOLUTIONS

[Q] nexus 7 completely dead?

Hi,
I have a nexus 7 2012 and it worked fine and runs CM 12. The other day I powered it off by pressing the power button then clicking the power off option in the power menu. When I turned it back on it didn't boot up and I ended up having to hold the power button for ages. Powered if off again the next day (only use it occasionally) and when I went to turn it back on it didn't boot again. This time though no matter how long I hold the button for or leave it on charge nothing happens.
I've tried everything from trying different charging cables, plugs, plugged it into laptop, pressing power + volume down and even pressing all 3 buttons. I've popped the back off and unplugged then plugged back in the battery. Nothing works there's no sign of life at all, no screen flickers no nothing I'm stumped. Think when I powered it off it was at 15% battery if that makes a difference?
Only conclusion I can come too is that the charging port is broke or the circuit. Sadly I don't have anything I can use to try and charge it using the four pin connector at the side to test it. Only thing I haven't tried is to "jump-start" the battery. Just take out battery and strip a usb cable and plug the power wires directly into the battery for half hour but not to sure whether to do that or not and wanna make sure I have exhausted all other options before trying that.
Any ideas?

Phone won't power on after removing usbc cable from desktop

Last night I had my phone connected to my computer to charger it per my normal routine before going to bed. I removed the USBC cable and the phone's screen instantly went black. Would not power on with holding the power button, power button and Volume + button together. None of the tricks I knew to try would work.
I laid down for the night and plugged it into the original charger and cable from OP, and the phone vibrated, showed the bootloader unlocked message, then back to black screen, never showed the boot animation. Intrigued, I then was able to get into the fast boot screen, I got excited and thought maybe by some chance there was a software/kernel issue and I could push the image from my desktop. So I unplugged the power cable and as soon as I did the phone instantly powered off.
Now prior to connecting the phone to the computer, the phone was at roughly 35% battery, so there was no way at any point that the battery was dead.
I left the phone connected to the oem charger and cable overnight, and upon waking up today the phone will still not turn on. I tried holding power and volume + for at least a minute and no signs of life.
I'm really at a loss here, I've had the phone less than 3 weeks, it's never been dropped or exposed to water.
I opened up a ticket for repair from OP but now I'm concerned that the phone is rooted and has TWRP, if they'll deny repair, even if it appears to be a hardware issue not software?
Are there any other tricks I can try?
Well as an update, I now know why I've seen many people say OP has horrible customer support. It took longer than it should have, but the repair facility says that replacing the mainboard fixed the problem. And sure enough my phone is charging and working as expected. Already updated, bootloader unlocked, twrp installed and magisk. Life is good. ?

[SOLVED] Stuck in boot loop: No image, short vibration every ~5s after battery drain

SOLVED: had display repalced.
Hey there!
I've had this Zenfone 3 Zoom ZE553KL for almost 2,5 years now and this is the first real issue I had with it.
One night I went to bed with ~30% battery remaining. When I woke up the phone was dead and holding the power button only made a short vibration. No image on screen.
Here's the things I tried:
Plugging it in: THe charging LED lights up and the phone vibrates quickly every 5 seconds or so
Leaving the battery to drain for 24h: The phone still starts vibrating when I press (or hold) the power button
Holding PWR and VOL+: The phone starts this vibrating cycle agian
Connecting to a PC via ADB: adb devices shows nothing. fastboot devices shows nothing. The phone had USB debugging enabled.
I did those things with and without the SIM card.
Any ideas how to troubleshoot from here?
Cheers!

Not much you can do. Try opening the phone and disconnect the battery for few minutes.

Disconnected for 5 min. After reconnecting, same behavior.
Will try leaving for 1h, although I doubt it would make any difference. After 5 min all caps should be discharged...

The storage is encrypted. The only way to recover the data is booting the current firmware, right? The last backup is a few weeks old...

Yea, it's encrypted by default. No way to recover it really if you don't boot the device into the os.
Also if the battery disconnection doesn't help, try disconnecting different parts that can be disconnected, like the screen, changing port, cameras etc. One at a time.
As a last resort will be to try to bypass the battery or change it.
I had something similar. I plugged it in and left it for several hours (I think about four or five) and then it turned on.
Mine did NOT vibrate every few seconds though like yours but maybe worth a shot.
Good luck and hope you get it working!
It was the display. Had it replaced and now the phone is working fine.
Thanks, guys!

I accidentally dropped my ROG 3. The screen had no scratches or any cracks at all, but the screen had no display. It's totally black. I can hear the sound and the vibration when I hold the power button. No charging LED lights. PC could not detect the phone. Thanks for this post. I need to replace the screen, and it's really expensive.
