Hi fellow Xiaomi entusiasts,
The moment I set foot in another country my Mi 9 started to randomly shutdown, that was annoying however I could just start it again and it was all good.
One week later and I can't start it at all. Last time was yesterday for about 10 minutes (and I could do the banking stuff I had to do).
Up to yesterday I had the impression it was something with the battery as letting it for several hours on the charger allowed me to turn it on again even though the percentage indicator never got less than 50%. Today after keeping it for the whole night on the charger it isn't turning on.
It's rooted with xiaomi.eu and magisk. Recovery mode also doesn't boot. When letting it on the charger no light or vibration happens.
Any ideas on how can I debug it without turning it on? Also, if I manage to get lucky and turn it on, what should I look for?
Thanks.
Have you tried plugging it into a computer? If you have what happened when you did?
I haven't yet, what should I expect?
Currently the phone has been charging for 3 days and when I press the power button the notification light blinks, nothing else happens.

Do you know the button press combination to get the fastboot mode and TWRP?
Rooted? Which firmware?
Yes, tried both power button + volume up and power button + volume down for 30 seconds.
It's rooted, I don't remember the exact firmware, I installed xiaomi.eu in the begging of August. I'll have more information on Friday once I get home.
Fast forward two months and the phone is dead. There is no Xiaomi assistance in Brazil, so I tried a general assistance and they said the main board is defective.
I found one other Mi 9 owner with the same problem. I'll have to sell it for the parts.

I have a brand new Nexus One bought on last year April. For some reason it wasn't to be used. Yesterday, I got it out of the package and charged it for ready to be powered on. Unfortunately, it reacted nothing as I pressed the power button! I took out the battery and put it into other Nexus One, it showed the battery was 100% charged.
I took back the battery and repacked it to this new Nexus One. I tried to press the power button more and more with data cable connected pc. Nothing happened. Just one time, the sceen lighted on and the "X" in four colors appeared! I didn't know why it was powered on. Maybe I pressed the trackball or volume up/down buttons, God know it.
The X sceen lasted almost for ten minutes and then sceen was off! Yes. It shutdown! I can't power it on anymore!
It seemed the hardware was OK. It may be the locked by the outdate android system. The android prestored in this phone is version 2.1.
Any advice is welcome. Thanks.
Can u you go in fastboot? Press power button+trackball..if so then you can recover your phone by unlocking bootloader and falshing custom recovery.
Sadly, It can't be power on and go in fastboot by pressing trackball+power button.
Any more advice?
Check the battery terminals just to make sure they're not dirty.. Sadly, you MUST be able to at least be able to boot something (hboot/fastboot) in order to troubleshoot anything software related. Sounds like you've got a hardware issue that could be one of (literally) a million things.
Sell it on EBay for parts. You can probably get $50-$60
you could try pressing pwr/vol-/trackball all at same time, hold down for around 30 seconds to make sure
commonly known as 3 finger salute
try power on without sdcard by manual methods and plugging in and plugging in with no battery
I have seen a video on YouTube on how to fix the power button which is known for messing up and how to turn it on. Search YouTube

is it that the power button is not working? that would be weird for a new phone though.
have you tried to turn it on using the "jump start" method?
connect the cable. led the charging led come on. remove the battery, wait for the led to go off (while cable is still connected) then pop the battery back in.
see if you can get it to start that way
When you plug charger cable in your Nexus, does the orange or green LED go on?
If one of them does and stays (green for full battery, orange otherwise) - then your problem is most likely the power button. It may not be the only problem, but at least the one that's stopping you from turning on your phone. You can try "jumpstarting" it by inserting battery while charger is connected.
If you don't see LEDs when plugged in - your phone is done.
If you see blinking LEDs - battery terminals might need cleaning/fixing, it usually happens when the battery is out of the phone.
Good evening everyone, I have a Nexus 7 8gb, but the thing is, I cannot turn it on now.
It happened as follows:
I was using it every now and then, mostly to read and play.
I was using the charger to charge my cellphone too (XTC Explorer) as it was a lot faster, being 2amp/h.
I updated the cell to 4.1 and at the same week noted the battery wasn't running that long, but blamed it to the rom.
The cellphone also took a lot longer to charge with the nexus charger, yet again I blamed the rom.
I noticed the Nex was at 8% while reading so decided to charge it, but I guess I forgotten.
The next time I wanted to use it it wouldn't turn on. I figure it had no battery.
I plugged the nexus charger to the nexus a whole night and in the morning it still wouldn't turn on.
I figured something must be wrong with the charger, so I tried with the cellphone and nook color charger, but both are .5 amps/hour.
It wouldn't charge, neither connected to the pc (also .5a/h via usb) so I tried a psp go charger, as it is rated at 1.5 amp/hour, much closer.
I connected it at night and saw the charging icon (white on black battery with the ray) and left it overnight.
The next morning it wouldn't turn on either.
I've bought it almost two months ago and I really enjoy it =) but now I'm desperate.
I cannot call google play for the warrant because I'm in Argentina, and I don't believe they will ship me a replacement, nor anything. This one my brother bought from them, but he went back to US a few days ago, and I didn't think of giving it to him to RMA.
I tried keeping the on button, for 5 secs, 30 sec, 90 secs, 120 secs, and no dice. Also tried holding the Up Volume key to restart it, but no chance.
Please help!
Had a similar issue to this over the weekend after not charging for 2 days and the battery going dead. I let it sit on the original charger overnight and for some reason it did not charge. It kept booting and shutting down once it booted due to a low battery warning. It eventually got to the point where the screen would go to fuzzy lines and light but no boot.
To finally get it working I did a combination of a few things but don't actually know what got it going.
Put it on a different (kindle) charger and let it sit for an hour or 2, did several hard resets holding both just the power and also the up/down volume and power all at the same time for up to 60 plus seconds. I switched back to the stock charger and did an additional hard boot by holding just the power for 30+ seconds and it started booting and charging.
I did however put it on the charge again last night and noticed this morning it was still at half battery and didn't get a charge. I ended up putting it on a mifi charger this morning and it's charging again so don't know what is up with the stock charger. Also, have all the latest updates to 4.2 as far as I know as there have been charging issues reported with earlier versions...

Try this, it just saved my device:

try holding down the volume DOWN and the power key for 10 seconds, then release the power key and keep the volume down key pressed, and it will force the unit to restart into the bootloader from any stage, its effectively like pushing the restart button on the front of a computer and constantly pressing the delete key to get into the bios.

Has anyone else had problems with this particular combination not turning back on? I flashed it several weeks ago, and every time the battery has died (its primary user is a toddler), it's been a hassle to get it to start back up: lots of fiddling with the power cord, power button, N button, leaving it alone, and trying again before it finally turns on. And that's after it'd be plugged in for the whole night.
Last night, I couldn't get it to turn on (even though I was messing with it for half the run time of Guardians of the Galaxy), so I left it plugged in. Usually, it acknowledges a button press by showing the dead battery or charging icon before blacking out again, but now the only thing that happens is the light turns green when I plug it in. No icons, no reaction to button presses.
Anyone know anything?
Did you tried turning it off by holding down the power button for >30sec?

Sorry this response is so late: I never got an email notification that someone had responded to my thread.
But yes, I've tried a ridiculous number of things. And before this, booting up the Nook from a dead battery was a real hassle. It took a solid 10 minutes of trying different power button/N button/boot screen button presses. Even before the battery died, it's been a bizarre, and immensely frustrating, quirk of having CM 12 on my Nook. And the internet seems to be largely resource-free on anything remotely related to this topic.
Hi, near-total novice here, but I've just put CM12 on my Nook HD+ and everything is great except I have the same power down problem. Both Reboot and Power Off result in my Nook rebooting.
Stuck on "please lock bootloader" screen when plugging in after depleting the battery
No button inputs work. The only solution seems to be waiting until the battery fully runs out and plugging it in again, after which it sometimes boots up. At least I got it to the first time, it failed just now. Maybe I need to hold some button combination while doing so?
How do I fix this properly? And what's a sure way to get it to boot from this? I'm already wasting half and hour on a minute's charge, God forbid I ever forget about it plugged in for longer. Would have to throw it in the drawer for a couple days and probably end up with some permanent burn-in too.
I haven't seen the screen in ages but doesn't it tell you to press the power button to acknowledge the unlocked bootloader? Also from memory it tells you it will automatically continue but it never does.
What seems to have done the trick is holding power&volume+ (probably just power is enough), so it loops through the 'empty battery' splash screen at least once. I think that's how I did it the first time too.

It never seemed to make any difference whether I pressed the power button or not, in fact it always booted up automatically after some time, this scenario excluded.
I suppose my problem might lie in the fact that buttons aren't working on that screen for whatever reason? Rather than it not going away automatically after battery depletion.
It is a bug in the bootloader. You can get out of the screen by disconnecting (!) the cable, and then holding all three buttons for multiple minutes until the device forcefully shuts down.
Before you do that, leave the phone plugged in for 10 minutes or so, so it can charge the battery to some extend. Then start the phone without (!) the cable plugged in, and wait until it boots into Android. When it is booted, you can safely plug in the cable and let it charge to 100%.
Just make sure you leave it for some minutes so it has enough charge to boot through the bootloader and start Android.

i had a similar problem after a failed attempt to boot into recovery.
for me the following did do the trick and booted my phone back into system:
- deplete battery completely
- plug in charger and keep power button pressed until phone is charged enough to attempt boot
- keep the power button pressed until nokia logo appears

How long is "multiple minutes"? I tried holding all three buttons at first, but gave up after probably a minute of nothing happening. I'll keep that in mind though.
Is there any hope for this to be fixed in the future?

Well, multiple definitly isn't one I haven't stopped the time yet, but expect waiting and pressing them for around 2 to 3 minutes, maybe even 5. It might sound stupid, but it will work.
About fixing it, I don't know. It might be a bug in the reference bootloader that Qualcomm provides for Snapdragon 835 chipsets, and I doubt that FIH / HMD have the resources to debug and fix that.
I get this same screen while the phone's powered off + charging and it's annoying.
I was going to start a thread to ask whether it's possible to charge this phone while it's turned off (without the screen being kept on) after unlocking the bootloader. I guess based on the posts in this thread, that's not possible? [emoji2357]

No, I guess it isn't. I've tried to plug it in while it's off and turn off as it's charging and in either case it resulted in the phone hanging up on that screen. I can confirm though that holding all three buttons for a while does turn it off and allow me to boot normally which is cool.
But is that possible with a locked bootloader anyway? Or does it always power on? I can't tell if I ever needed it to charge like that.
I see this "warning" message only on android pie builds, it doesn't seem on oreo builds. I think problem seems that kernel dependent (oreo is on 4.4.78 and pie is on 4.4.153). There is one way to get rid of that message, as @THMSP said, holding all 3 buttons pressed during 2-3 minutes and let it to be shuted down. Then, let the device to boot normally and plug in. Finally you shouldn't connect to charger when it's turned off on any pie build.
Hello all. My rog 2 phone went completely dead and not able to turn on in any mode. Any help in this will be highly appreciated

Yup.. I hv tried all the above...and also tried connecting to laptop thru USB cable.. but absolutely nothing happening.. it's dead as a Brick
What did you do before
Nothing actually.. went to bed in the night and kept the phone aside.. morning it was off thought battery empty and kept for charging. But even after an hour I noticed it wasnt charging and I cudnt turn it on either..
maybe open back cover and see What happened?
replace battery or What?
or replace Screen?
have you done any system updates or opened auto update?
There was an ott update that day which got auto updated..
Mostly is that OTA hard bricked your device. Your device ran out of battery while installing it.
The mobile had enough battery and the update got fully installed over wifi. After that I hv used the phone too. In the night I went to sleep keeping the phone aside and morning this happened.
Maybe Another OTA came and bricked your device.
My Y9 Prime had recieved 2 updates in a row so I can confirm it is possible.
if that is the case I cannot help you but if it is battery bug（like Note 8 battery drained overnight and battery failed）you can try reconnect the battery or replace it but I am a noob of doing that
Do you have spare phones?
What happens when plugged to computer?
Ohh. 2 OTA updates....
No sound or anything Wen plugged to comp. It's still dead.. tried all combination.
then mostly 2ota bug or battery bug
if screen bug you will hear vibration
Ohh ok.. any solution for this...???
