One stuck on, wont soft reboot- home and return flashing - One (M7) Q&A, Help & Troubleshooting

I think I was holding down the power while it was locked. it didnt reboot bus is now instead stuck with a black backlit display panel. home and return is on permanently and the charge light is also lit, despite not being plugged in.
holding down te power button for any length of time just makes the home and return flash for a minute and then back to solid.
no combination of power and volume up/down makes any difference. just flashing home and return lights.
HELP
do I just have to wait for the battery to run out?

Wait I'm a bit confused ...what current state is your phone in? Is it booted up if it is just adb that *****

it was booted up. now it's just a dark screen with backlight, home and return buttons and charge light lit
plugging in USB and runningg adb reboot just says device not found

actually- when I plug it into USB it appears as in device manager for a few seconds
adb reboot during that period gives 'device offline' rather than device not found...

[Q]HOW TO RECOVER A HARD Bricked Sony XZC6002?

This is a HARD Bricked phone that first started going berserk after a partial install of a SONY software update. The phone would flash the home screen and continually vibrate. I forced it down with power off. Did not know what I was doing and believe I converted a soft brick to a hard brick. The soft brick at first responded to power button and volume up button to reboot. After that point it became more and more unresponsive to complete death.
It is not recognized by PC (even in the device manager) when plugged into USB port on PC. NO LED or any lights on the phone at all! No red charging LED with charger plugged in, No Sony screen icon, no vibration with power button pushed hard for >10 seconds (with and without pushing up/down volume). The ONLY response I get is an audible windows sound coming from my PC as long as I hold the power and volume up button down.
I have left the phone off a charger for >48 hours and then placed it on the charger for 6-7 hours. Still no red LED while on the phone was on the charger. Reason for me doing this was my reading notes that Sony had a battery error issue that could only be solved by removing the battery or draining it completely. Recharging the battery was suppose to be a fix. A recent poster did this (removed the battery) which is a job and was able to get a red LED but nothing else. There was no reply.
My readings also indicated that there are a number of people with this problem (hard bricked phone) involved with download or install of their software Sony reportedly has a fix to install to correct it. I am a day late and a dollar short.
BTW, the Sony PC companion works up until I connect the phone to the PC and then an error message appears to make sure battery is charged to 80% before proceeding. Ignoring that brings up a troubleshooting screen prompting holding the power button and volume up button for 10 seconds. This is where I get an audible windows connect/disconnect sound coming from my PC that will keep sounding as long ass I hold the buttons down and stops after I remove them. Could this possibly be just a battery issue? Any help is greatly appreciated.

Firstly, you've made one major mistake when you've turned off your phone by using force. It can completely brick your phone forever.
Secondly, if you can hear any sound when connect your phone to USB, then thats mean, that your phone is still in minimal functionality. However, you can give a try to buy a new battery and see, how it goes.
It's better to buy extra battery, than change the whole phone, am I right?
And try to leave your phone without touching it for couple days I think. Maybe your battery somehow has got any fault or it has been faulted when you've force-shutted the phone.
Just give a try and that's all. You can't do anything else, except if you know and you're ready for phone disassembly. If none of my suggested methods will work, then try some other tutorials, you can search for them in XZ category's. I've forgotten how that thread is named, but you can search by some key-words, like : ultimate recovery, back to life, unbrick and etc.,
I hope my information is all correct and helpful, if not, then sorry for disturbation for nothing

My gut tells me that the battery is OK but needs to be recharged. Apparently there is something that will not allow the battery to recharge unless it is removed or drained to zero. I thought I drained it to zero but perhaps not. The other case where the battery was removed and was then able to show a red LED apparently allowed the battery to recycle. That's as far as he got.
In the mean time I'm taking your advise and just letting the phone sit until someone makes a suggestion or I get tired of looking at it.
Thank you for your time and suggestions.
Can you enter the "fastboot" mode (unlocked bootloader) /"flash mode" (locked bootloader) ?
Hold "volume down" button and connect with USB cable to the pc.
So first hold "volume down" button and then connect with USB cable to the pc while holding the "volume down" button. Let go the "volume down" when a green led on your phone appears.
You can still enter the "flash mode" if the green led appears.
Hold "volume up" button and connect with USB cable to the pc.
So first hold "volume up" button and then connect with USB cable to the pc while holding the "volume up" button. Let go the "volume up" when a blue led on your phone appears.
If the blue led appears on your phone you can still enter the "fastboot mode".
There is still hope if the green/blue leds appear on your phone (meaning you can still enter "flash mode" / "fastboot mode".

It is HARD Bricked. Unresponsive to all of the above w/o any LED response.
Has your phone an unlocked bootloader?
The phone was purchased from Sony and was factory unlocked. It was running fine until the new update from Sony was installed. I believe the update was related to the OS which is 4.4.4.

Screen won't turn on - Bricked?

I was in the middle of installing drivers for my device and was getting from ADB type errors using the supertool.
I didn't get far, and after getting the error i unplugged and turned off my screen and now it won't turn back on.
When i plug it into my computer it won't detect the device.
I had it for less than 30 minutes! Any advice here?
:sadly i've rooted and flashed many a phone, not sure what i did wrong here:
Hold vol down and power until it vibrates, then let go of power and hold vol down till fastboot. If you can't get to that, you're probably pretty bricked.
Note, there does not appear to be a vibrate motor in the Fire7. So no vibrate feedback.

N6 power button stopped working, now I can't turn phone on

My power button stopped working a couple days ago but I was still able to wake device with volume buttons. I was worried that if my phone were to shut off I wouldn't be able to turn it back on so I booted into bootloader and was going to try and flash "oem off-mode-charge 0" (which should then make the phone power on when plugged into charger).
At the time I couldn't detect the device using fastboot and as I was searching around on my computer the screen on the phone turned off (was in bootloader at the time). I'm not sure at this point if my phone was on and that both the power and volume buttons were not waking device or if the phone turned itself off.
I have tried the hold the volume down and plug the charger in trick to try and get back into bootloader but nothing happens. When I plug phone into my computer it takes about 20 seconds but I get the little windows ding that something has been connected but phone is still not responsive. I'm starting to think I'm a little screwed here but welcome any input.
You just looking to get the screen to light up so you can implement a way to use the device without the power button? You could try gravity screen or something but first things first...
If its not lighting up on plugin have you tried connecting to a computer and opening ADB and issuing the command adb devices followed with adb reboot. If you wanna go back to bootloader just adb reboot-bootloader. That will restart device so screen is back on and I would turn on the Ambient Display mode so when you pick it up the screen comes on or get a volume power button app or gravity screen app that turns on when you take it out of pocket. Thats all I can suggest and hope any of this helps.
With phone plugged into computer, nothing shows up when I check adb devices or fastboot devices. I guess I'm unsure on what state my phone is in. None of the buttons do anything and nothing happens when I plug my phone into my wall charger (no charge light or screen on). The only response I can get is when I plug the phone into my computer windows makes a noise.
Anyone know what happens when a powered off phone gets plugged into the computer? Does windows make the little noise indicating a device has been plugged in even with it off?
It does not make a noise if its off.. That much I know. Interesting though. Are you sure you have the correct drivers installed for your nexus phone if you are on windows. Go into hardware manager by right clicking on my computer and make sure that its reading it correctly in usb devices without a yellow triangle next to it.
I should have the correct drivers. I just went ahead and reinstalled them through the nexus toolkit. In device manager it says: unknown USB device (device descriptor request failed).
I checked adb devices before all this happened and it displayed correctly. I then rebooted into the bootloader but the fastboot devices command did not show anything. It was shortly after that that the screen turned off. Will the screen normally time out when in the bootloader? I'm wondering if my phone is still in the bootloader with the screen off and both power and volume buttons non functional.
Only thing I can think of is to wait for it to die, then volume down + plug in to pc and when bootloader screen appears issue command fastboot continue and it should boot up. Then get something to remap key or an app. If this all fails after it dies and you restart it assuming debugging wasnt on or its just reading phone as media device of sorts not allowing adb then you may have to get the power button assembly possibly and install it yourself or open the back case and hit the power contact under the button and see if you can get it on. Thats all the ideas I have.
I'd also suggest that after you reinstalled drivers make sure you did a reboot and then plug in the device and also try using a different USB port and or USB cord also as odd as that sounds Ive seen it work before. Im pretty tapped on ideas tho. Do you know if you had usb debugging enabled?

Ok, cool. I'll take a look.
Managed to get it back into the bootloader this morning. So I guess this is a PSA, if your screen times out while in the bootloader, the volume keys will not wake device so since my power button is broken I couldn't wake it. At that point, the phone is in a state where it cannot receive any fastboot commands, even though it is in bootloader with the screen off. What I had to do was wait overnight for the battery to drain and have the phone power itself off. At this point the volume down plus plug in charger trick worked to get it back into the bootloader with screen on. At that point I was able to 'fastboot reboot' back into system.
Thanks for the insight people

Driver issue.
Remove/uninstall the drivers from your PC when the phone is connected.
After that reinstall the adb/fastboot drivers.
N6 - Power mapped to VOL DOWN; turned off and can't get it back on
Hi all, I had to remap my power button - I mapped it to VOLUME DOWN. The other day I voluntarily powered down my N6 at a test center.....and haven't been able to get it to respond since. I do have a Pixel 2 XL on the way - but not that sure I'll want to keep it. The N6 is so sweet.
I've tried holding the volume buttons (POWER and VOLUME UP) for like a minute, but nothing. When I charge it, I see the battery symbol (full) but only for about 5 seconds.
ADB does not see any connected devices. Wug's NRT does not see any connected devices. I'm at a loss and afraid that I've lost my N6 and will have to use the Pixel 2 XL regardless what I think about it.
Any other ideas?

Wow - just got my N6 to boot using this little tip I found on Reddit - https://www.reddit.com/r/AndroidQue...ny_way_to_turn_on_phone_without_power_button/
I was holding down the Vol Up and Power buttons (which are both the Volume bar since I remapped my power to Vol Down), but I hit 'enter' on the 'fastboot continue' text in the CMD prompt just after I plugged in the USB and the battery icon came up. It booted into bootloader mode briefly first, then went into system reboot. Whew!
I think your button assembly is broken and I would replace it. You could try the work around in Broken power button, any way to boot? by altarity, post #3.

LOS13 MM [titan] misbehave

Hello,
This device had been flashed with LOS 13. It was working and functional, but some configuration(?) lead it to dead(?) screen! The Power, Volume +/- buttons aren't able to bring it back, neither touch screen. LED light keeps blinking.
I can't say for sure, but the option 'Do not turn screen on when pluging microUSB power charger/AC outlet.' was toggled to TRUE and some other tweaks I did at same time. So device suspended, then connected power cabble, next pressed power button. Frustration time, device went off, no signal of display viewability/working/etc.
I started trying to debug what happened: attached to Computer USB, from where it'd flashed, terminal prompt, ./adb devices and ./fastboot devices has no listing of it. Again, the white LED light keeps blinking.
What else can I do? Please help!? I have no working device atm and all ears to follow instructions/troubleshoot attempts/etc!

[SM-T510/T515] 2019 Galaxy Tab A 10.1 Hard Resets

Here's a quick reference for how to reboot and reset your 2019 Galaxy Tab A 10.1 (SM-T510/T515) using the hardware buttons:
Force restart:
- If your device is frozen and unresponsive, press and hold the Volume Down + Power keys simultaneously for more than 7 seconds to restart it.
Boot to Recovery Mode:
- Power off the device
- Press and hold the Volume Up + Power keys at the same time.
- Release both keys when you see Recovery Mode.
Boot to Download Mode:
- Disconnect the USB cable
- Power off the device
- Press and hold the Volume Down + Volume Up keys
- Insert the USB cable
Boot to Safe Mode:
- Power off the device
- Press and hold the Power key.
- When the boot logo appears, release the Power key and then press and hold the Volume Down key.
- Continue to hold the Volume Down key until the device finishes restarting.
- Safe Mode will display in the bottom left corner of the screen.
Since there is no Bixby button, these combinations are different than the Galaxy S10. If you know of additional combinations, please contribute to the discussion below and I'll consolidate here.
If there’s no response on your device or you're stuck in a boot loop, then you might need to wait for the battery to drain. The 2019 Galaxy Tab A 10.1 has a non-removable battery pack, so disconnecting that isn't an option. Hopefully, the system reverts to its normal function with a cold boot. This can take time if the battery has high charge left at time of failure. Depending on how fast your battery drains, this can mean waiting for a few hours to several days.
UPDATE: With the right timing, you can break out of a boot loop into Download Mode...but it's tricky:
Insert USB Type C cable connected to your PC
Press and hold the Power and Volume Down keys for exactly 7 seconds (hard reset)
Release the Power key and press and hold both Volume Up & Down keys (enter Download Mode)
If you don't see the blue bootloader unlock warning screen, keep repeating the above two steps
The trick here is that you're trying to time your switch to the Download Mode keys for the exact moment the hard reset takes effect. If you see the boot logo while still holding the first key combination, it's too late. If you switch too early, you won't trigger the hard reset.

Thanks, that was an error in my initial post. I was figuring these out by trial and error, but it turns out that our hard resets are basically the same as for the Galaxy M30, which also uses the Exynos 7904 SoC and has no Bixby key.

Yes, I did the same way
US version
1. Enable OEM Unlock
2. Turn the tablet off and unplug the cable
3. Press and hold both volume up and volume down buttons and plug USB cable to host computer
4. You will get wipe screen. Long press volume up to unlock the bootloader.
Now I have to find matching ROM and patch the boot.img and flash.
I believe you have to disable Vault Keeper to keep root intact.
Brand new out the box 11am this morning.
Opened the parcel cool no damage. Powered up fine, had a mess with it, no problems check the speakers were fine and no issues plugged it on charge to 100% took it off and left it for an hour or so, went back to it and physically used it to use Facebook and play candy crush cool no problems. Took a few photos and no problems again. Put it on the side still on near 90% and went back to it 30 minutes later completely off and won’t turn back on, tried charging it nothing no sign of life, tried rebooting it and still nothing. Please tell me that this is not the end and I need to get a replacement... ?*

I’ve not even been able to get it back on, I’ve attemp a reboot countless of times and still nothing rectifys it. I spoke with Samsung they feel it’s a major fault with the tablet and have told me to request a replacement from my provider or even a refund.
