Hi guys,
I have a Nexus 7 2012 which has become almost completely unresponsive.
Possible cause:
Last thing I remember is that I had it in my pocket and when I looked at it later - it was in bootloader mode. I pressed the power button and since then I have not been able to wake it up.
The device does not charge because I cannot feel the battery to be warm after a whole night of charging. I cannot turn it on no matter how long I keep the power button presses. I have tries two minutes on the clock. I cannot enter into bootloader by pressing power and volume down, even though I keep pressing them for two minutes also on the clock.
So I removed the back cover and pulled out the battery connector. Reconnected but there has been no change in condition.
The device shows the following signs of life.
When the battery plug is pulled out I connect it to my Windows 8 PC via the USB cable and I push on the Power button for about 10 seconds, I get in the Windows Device Manager in Other Devices a new(unrecognized) device named APX. When I pull out the USB cable the I hear the windows usb disconnect sound and the device disappears.
When I connect the battery, I connect the USB to my PC. I don't push any buttons and after 15 or so seconds I get a message USB device not recognized in the USB controllers section of the Windows Device Manager. When I press and hold the Power button (or Power and volume down buttons), after 10 sec The unrecognized device is moved to the Other Devices section and again is called APX.
I cannot turn it on. I cannon boot into bootloader. I have tried almost any approached listed here an on Google (about 10 different step by step guides) and I remain in this position.
Please help me bring it back to life. Hope it's possible. What should I try. I am fairly technical and can understand most instructions.
Had same problem,the only solution found charging via dock station.My 5 years old child broke usb port trying insert cable.
Hello,
Today my sister charged her Asus Zenfone 5 and rebooted it, it simply didn't turn on. I tried turning it on, pressing the power button for 30sec, pressing it with volume up or down or both.
The device isn't charging and doesn't respond to charging or respond to anything in particular.
But when connecting it to my computer it updated the device manager as an "unknown device"
What should I do? Contact Asus support center? Anything else? If you have any idea please suggest it here, I'll try..
NO MODIFICATIONS WERE DONE TO THE DEVICE IT IS STOCK UNMODIFIED! (so it's not a faulty flash. Mod or anything)
So last night I forgot to charge my phone and when I wake up it's died.
I tried to charge it, but the led is blinking and then it booting up to Mi Logo (not androidone logo, before that, where there is "Unlocked" bootloader word) and it just stuck there.
I can't turn it off, nor restart. I don't know is it software faulty or my power button is not working well.
I've tried pressing power button for minutes, + vol down, +vol up&down, nothing work.
Is there is another way to restart/go to fastboot from adb maybe? (because when I tried to connect my phone to PC, the PC detected it), or if you have any other suggestion, thanks before.
Open the phone and disconnect the battery for a minute and try again
Same happened with me still phone is dead
I think you have to open the phone and disconnect the battery
Hello guys. So I was using my POCO M3 when the battery ran out and it went off. I thought everything was normal until I went home and tried to charge it. Its been hours of trying different chargers but to no avail. The device won't power on, it won't charge... It's just dead. Please help me fix this.... I really need my device back
POCO M3 Was Not Powering On....
But it HAS powered on finally, and here's how I resolved it:
1. I triggered a FastBoot by pressing down the lower volume rocker and the power button for some seconds. The "FastBoot" screen stayed on for sometime ( I dunno how long) and then went off again. Then I waited for some minutes before turning the POCO M3 on, and it works.
Okay, weird problem here. I'd like to unlock the bootloader on the Samsung Galaxy Tab A 8.0 2019, but can't seem to recreate the blue screen asking if I'd like to enter download mode or unlock the bootloader. I've read that I should press both volume keys and plug in the device while holding the keys until that blue screen appears. However, for me this doesn't do anything except "boot" the charging thing (where you see the current battery percentage), I held the keys for about 30 seconds but didn't get anything different. When I press Power + Volume up I get that Android Recovery screen, but can't seem to unlock the bootloader from there either. I tried rebooting to bootloader, but that just gave me the download mode instantly (on a black screen with my tablet logo) - this way I also had no choice to unlock the bootloader. Anyone know what I should do here? I'm kind of stuck
Edit: fastboot oem unlock just tells me it's waiting for device, however adb can find my device (OEM unlocking and USB debugging is on)

With the tablet off, plug the cable into a PC only. (not a charger) Then, while holding down both vol up and down, plug the cable into the tablet. After a couple of second, the screen should appear with the unlock option instructions.

I am doing that, but the tablet just shows the charging animation that appears when the device is off. By the way, the device is on Android 11, is that maybe the problem somehow?

It has nothing to do with what version of Android you are on. It should enter the download mode before Android even starts to load. Have you tried using another USB cable? They can be very touchy about detecting the data connection rather than just power. As I said, I don't have a 290, but on my 500 it helps to connect to the PC via a USB 2.0 hub rather than directly to the PC.

I now tried 3 or 4 different cables with no luck. I'm still assuming that it has something to do with the software, and I noticed today that the tablet actually runs OneUI Core, whatever that means.
