There was a thread about this in development, but it's gone silent.
I powered off my device, then held Volume Up and Power buttons for a few seconds. The phone vibrated a couple times and the amber LED started blinking on and off. The screen stays black, and it doesn't seem like any of the physical buttons do anything in this state. I tried every button on the phone, tried holding Power, and tried holding various button combinations -- nothing.
If I then plug it into USB, the computer recognizes a "Qualcomm CDMA Technologies MSM" device, but the drivers do not install successfully.
So, what exactly is this? My Google searches haven't turned up any clear info about what it is, what it does, or if it's useful to us in some way.

Hello everyone
I have a serious problem here, was about to give up on the phone but there seems to be some hope out of this mess.
Okay, I was doing a task 29 through HSPL4.exe when it stuck up at 24% and gave Rom update error, (details read something like there has been a communication error etc.). The phone screen showed the Rom update failure screen , when I reset the phone it doesn't power up at all. No bootloader, no vibrations or LEDs, nothing.
Only, when I press the red (end call/ power) button and then press volume up for some time, the phone vibrates twice and the green LED lights up, thats it, the screen remains blank.. When I connect it to USB, my PC detects it, but asks for a driver that I don't seem to have, although I do have Activesync installed (i'm using XP).
Please somebody, get me out of this mess, I'd be so grateful.. Thank you.
Did you try booting into that one screen, forgot its name
....the rainbow screen
do u have hd2 toolkit? btw...if you can get into your bootloader there is definitly hope. long live hd2!!!!!!
I am having the same issue however mine came about when my hd2 got wet after that all it does is vibrate once and nothing happens the LED comes up for like a sec and nothing else happens...
Yeah, it doesn't go to the bootloader when I press the vol down button. But it is detected by my computer when I connect it to USB, isn't there a way it could be recovered thru there somehow?
okay so i left my phone sitting for a while and now it vibrates the bottom buttons turn on when i touch them and the led is in orange and my computer recognizes it too but no display at all....
Hello all,
My mother got an a500 about seven months ago and the other day she put it to charge and the next day it wouldn't turn on at all, just a black screen. When the charger is plugged in, the power button glows white. Take it off charge and the light goes out and that's all it will do.
I have tried searching through multiple forums and I have tried all the solutions I have found. I tried pressing the reset button near the usb plug, I tried a hard reset by holding the power and volume + buttons multiple ways, i.e. I held them both for thirty seconds, held the vol button and pressed power for three seconds and about every other iteration I could find. Nothing happened not even a vibration like from what I've read it is supposed to do. I downloaded the update.acer.zip file and put it on an sd card and tried flashing it by holding the power and vol - buttons, still nothing.
The tab has not been moded in any way, however, God only knows what apps my mother way have downloaded to it...
I am at my wits end and I don't know if I'm doing something wrong or what. Any help would be greatly appreciated. I am a noob so it wouldn't surprise me if I am not doing the flashing right or if I have the wrong files, all the links I found on the forums were non functional and I had to download it from filecorp.com.
Thanks in advance!

The white light when plugged to the charger just indicates it's fully charged.
Test 1. Press and hold the PWR button for 7 seconds, release, wait a couple seconds to see if it responds, then press and hold for another 7 seconds. See if it responds.This is to check if the tab is in Sleep of Death (SOD)
Test 2. Using a paper clip, press and hold the pinhole reset (near USB) and then press and hold PWR. After 4 seconds release PWR, 1 second later release pinhole. See if is vibrates and goes into APX mode, (tab should vibrate once with a black screen and white PWR button) if it does, press and hold PWR only for a few seconds. Wait a couple seconds, then PWR on tab by holding PWR about 6 or 7 seconds.
Test 2 is just to see if the tab responds to anything,
If you can't get any response from the above, then it's best to turn it in for repair.

@Moscow Desire: he pressed the reset button already so it is probably not SoD. Unless SoD makes reset button unresponsive too.
My tab does not vibrate when entering APX mode at all. Only the white power button LED turns on and the screen stays off.
@Core645: try this at first
- disconnect charger so the LED turns off
- hold power button for about 5 seconds
If the power button LED turns white and nothing else is happening then your tab is stuck in APX mode. You can confirm this by connecting micro USB cable from your PC. If you have windows it'll ask for drivers for Nvidia Download Mode or something like that.
Then check what Moscow Desire suggests with the reset button. I only ask you do my check at first because by holding reset you would achieve the same result and you wouldn't know if it is stuck in APX or you just forced it to APX by holding reset button.
My N4 won't power on, at all. I've tried doing the fix where you hold power and volume down and plug it in, and it'll go to recovery, the Google sign, then it'll power off and flash a single red light before going dead again. When I plug it in, without touching any buttons, one red light flashes then nothing else happens. Oh, and I've kept it charging for 2 hours and nothing different has happened. What's up with it? Did I brick my advice?
[GUIDE] How to make your "bricked" device show up as Qualcomm 9008 instead of 900E
Now, some people who have tried the official recovery tool have experienced that the MsmDownloadTool didn't work for them, because their device actually didn't show up as a Qualcomm 9008, but rather a 900E.
To fix this, instead of holding power button for 20 seconds, and holding the volume up for 10 seconds and then connecting, do this:
1. Hold down power button for 20+ seconds like you're used to.
2. Connect the phone to your PC
3. When connected, press and hold volume up, volume down, and power button at the same time
4. The device will after some time show up as 9008 in Windows device manager (To know when to stop holding the buttons, look at device manager while holding them down)
I hope I helped some of you that think your device is completely broken
I honestly though my Oneplus 9 Pro was done for. Thank you, the steps worked perfectly.
Hello. My phone does not boot. I did no modification to the software and i was using it just as a daily driver. When i press the power button the notification led lights up red-green-green and loops 3 times. When i connect it to my pc i see "㌲㔴㜶㤸" in the device manager. Key combinations like power on+ volume up or down does nothing. I already checked out this thread but did not help (https://forum.xda-developers.com/p8lite/help/huawei-p8-blinks-red-green-green-red-t3546038). I only need to get my data out of the phone. I don't care if it works again or not. How can i access my data? Thank you.
