I was on the latest MIUI (9.something), boot-loader unlocked, redwolf recovery (v27), last seen battery was ~50% charged (before going off).
And, I was using my phone. Suddenly screen goes off and nothing comes up. I tried to restart, it doesn't work.
Finally I googled the problem and tried these things:
1) Press power button 5 times, then try to start the phone by long pressing power button.
Result: Screen open up, that initial screen with MIUI logo, I keep the button pressed, screen goes off and instantly starts again with booting started. Now, as soon as boot finishes, that *low-power* sound comes and it switches off.
2) Press power button 5 times, then try to start the phone by long pressing power button. This time when the screen comes up first time, I press (vol-up + power) to boot to recovery.
Result: As expected. That screen goes off and instantly another screen comes up with the recovery splash screen. Recovery comes up. There on the top, it shows two weird stats: (CPU temp 105 deg C, battery 0%).
3) Press power button 5 times, then try to start the phone by long pressing power button. This time don't press anything on the first screen.
Result: The screen goes off and that's it.
Some weird symptoms worth knowing:
1) Whenever I plug the charging cable (either with charger or, laptop) it just do not boot, neither to system nor to recovery.
2) The micro-USB port is damaged I guess. Last time (a day before all this), I tried to connect phone to my laptop but the socked seemed lose. It was just not connecting, rather fluctuating a bit.
3) Whenever I plug the charging/data cable (either with charger or, laptop) while booting or, while in recovery it suddenly switches off.
either your battery got badly damaged, or your device got fried.
First, I'd agree on the first commenter and support you taking the device to any android service center to check whether your battery or phone got fried. If it's done and proved nothing is wrong with my battery/phone I'd buy an EDL deep flash cable (I bought one for dirt cheap, 5 dollars) and try to solve my problem via deep flash, edl emergency download mode. There are tons of how to do tutorials on the official Xiaomi forums. Good luck with that, my friend!
I've updated something. Please see it.
How would I use edl if port is not working properly? See the original ques. again. I've updated it.

My 5.0 is hard bricked. Black screen, won't charge, won't turn on. When plugged into outlet or computer, still black screen.
I rooted it back in December with no problems until today. Decided to plug it into an outlet to charge it since battery was around 50%. After about 30 minutes, used it to check weather, etc., then I did a quick push of the on/off switch to turn off the screen. About 2 minutes later, went to turn it on and got the black screen. I decided to leave it plugged into an outlet for about 1 hour and still nothing.
Looking at other, similar, bricked posts for the 5.0, doesn't seem applicable to this completely dead device (wasn't installing a rom or doing anything unusual).
Any help is greatly appreciated.

I was able to fix the problem, without losing any data, by going into recovery. For others who may run into similar issues, I did the following:
Pressed the power and volume up key simultaneously for about 10 seconds until the SAMSUNG logo appeared.
Selected 'reboot system now' and pressed the home button.
Hi there,
I have an issue with my Samsung Galaxy S3; had it for a few years on O2 network in the UK. Recently, I left my phone to charge over night after the battery ran out of charge. I woke up to find no charge LED on the phone, and I couldn't turn it on.
I have tried the following things to power it up:
- booting it up in recovery mode (Home button, power button and Volume DOWN simultaneously).
- taking out the battery, pressing the power button a few times, then starting the phone up again with the battery in the phone.
- taking out the battery, pressing the power button and holding it for 10 seconds, and doing both normal power up, and recovery mode.
Now, a week later, after my phone completely died (and having to do with a Nokia Lumia 610 replacement), I came across a YouTube video in which someone recommends to plug it via USB into the computer, taking out SD Card and booting it up through recovery mode. Voila! I was amazed to see that it booted up; I had my menu and everything.
So I charged it to about 10% via the PC, and decharged it back down to zero. Plugged it back into the socket, and again, not a single sign of life from the phone.
To summarize, the phone only turns on via PC with USB connection, and fails to charge through the socket. I'm on Stock, non-rooted phone; with Android 4.3 and Kernel 3.0.31-2168382. When I try to do a software update, it tells me that I have the latest one. eMMC check app also tells me that I have an insane chip.
Where do I begin looking for a fix? I would be forever grateful for your help!
Hello,
First, sorry for my english
So, I had a S2 for a while, and one day, when trying to get another ROM etc, I unplugged the phone at a wrong moment, and I think the motherboard was dead. I bought a new motherboard on Internet, but the power button was broken (and I don't have tools to repair tiny things)
And when I try to boot him (the tricky thing to plug usb, remove battery and get her back quickly), it boot up normally, and the screen become unresponsive after 10 sec. I think all other buttons works, I have the vibration. And after 10 other seconds, it restart.
Another strange thing : if I plug a mouse with OTG, I can move the mouse, but after these 10 sec I can't click anywhere, but still move. And it restart.
(It's not 10 sec perfectly, it's less)
Like it's a new motherboard (occasional, so it's the configuration of the man who sell me the motherboard) the usb debugging is off, and I don't have the time to set it on.
So I can't use ODIN, I can't get to recovery or dowload mode.
Any advice ? Thanks
Hi,
I got hold of one of these tablets that appeared dead, left it charging overnight and it started without issue, the battery was at 67% at this point.
I then shut it down and held the Home + VolUp + Power to enter download mode as I wanted to install TWRP.
Nothing happened, but not only that, the tablet failed to boot again whatsoever. I took the back off and unplugged the battery, held the power button down for 30-40 seconds, reattached battery, still nothing, so I decided to leave it on charge for a bit more and try to figure it out later.
Later came along, and I picked up the tablet and for some reason pushed the home button 3 times and it displayed the battery icon, showing 100%, great!
It still won't boot though and I haven;t been able to reproduce whatever I did to get it to show the battery icon again.
I've tried every combination of holding down Home/VolUp/VolDown and Power that I can think of for different amounts of time and still nothing.
Had it plugged into the computer too and monitored dmesg for any signs of life and still nothing.
I'm thinking (but hoping not) that it might be a physical problem with the power button, but it feels fine when pressed.
Is there some magic trick that I don't know about that could help here?
Many thanks.,
g
EDIT: I have left it plugged in for a few hours and periodically the battery icon appears for a while (now at 99%), then disappears. Tried to switch it on with the power button while the icon is on the screen but no go, same with different button combos.
Hello,
I was playing a game on my Black Shark 3 Pro and it just shutoff. Now, if I press and hold the power button, nothing happens. If I plug the charger in, it doesn't charge. The phone seems to be completely dead.
Has anyone else experienced anything like this before and what ended up happening? Is this something that can even be diagnosed if I take it to a repair place? I'm assuming they'll have to take it apart and if they can't fix it, I'll get charged anyway for the work of taking it apart. Is there any hope?
Thanks,
Ben
While this is not normal behavior, here are some things you can try. First, power-cycle the device by holding the power button for 20 seconds, 5 times. Attempt to start the phone by holding down the power button and the volume-down button at the same time. This will start recovery mode where you can perform a factory reset. If this does not solve your problem, please follow these steps:
1) Let your phone rest for 12 hours (do not charge);
2) Charge with the official charger and cable for 6 hours;
3) After 6 hours, disconnect then reconnect your phone to the charger. A low battery screen should appear;
4) Do not attempt to boot. Allow it charge for 1 more hour;
5) After 1 hour, your device should be ready to boot and power-on.
if those methods don't work,give your phone to phone repair place
