Xiaomi Mi 9T Pro not turning on - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

I recently (just over a month ago) bought a Xiaomi Mi 9T Pro and have had no issues with the phone until now. I had a couple of pop up notifications saying something about my phone being too low of a temperature. I thought I'd just reboot the phone to see if that fixes it. However, now it won't turn back on with only the MI logo appearing for a brief moment (probably less than a second) before turning back off. I was wondering if anyone else had this issue and if there was some sort of way I could fix it myself without voiding the manufacturer warranty (ideally). I've already emailed the manufacturer and the retailer I bought the phone off of and am awaiting a reply from them. Thanks in advance.

Thanks for the quick response. However, when I tried that, the same thing happens as it would when I try to turn it on normally (the MI logo appears for a split second to only fade away or disappear instantaneously).

can't you just reflash the stock?

It doesn't pop up on my computer whenever I plug it in, so I don't think I can do that.

I have and the MI logo just flashes on and off the screen.

What it looks like

This is basically what happens when I hold the power button down or hold the power button down with the volume up button (flashing on and off once when just trying to turn it on normally).

May be group members of telegram can help you .. there are many people out there in telegram, install that telegram app on PC and discuss about your problem..

You don't understand! You have to hold Volume down with power button!

Then you totally ****ed up your phone. You need to reflash it via EDL. if it won't work maybe some component is ****ed up.

Try to connect the charger and after power on.
Or maybe the temperature sensor from inside of battery is damage ( it's reading show verry low temperature ) Try to warm little your phone and after power on.

i dont man i think shes screwed
It is tough to understand what exactly happened but to me it sounds like he downloaded an older firmware rev and then took an OTA, which generally leads to the exact problem, a brick.

[Q] [HELP] My MotoG died today, for no reason. No boot or any notifications.

Hi everyone!!
Today, I woke up, and noticed that my Moto G 2nd Gen is died.
Honestly.. i don't understood what happened exactly. My phone was absolutely clean, no rom, no hacks, no strange apps, NOTHING!
Absolutely genuine and with just a few (famous) apps, like Tapatalk, Skype, Facebook etc..
Someone maybe knows what problem is it? Hope to receive help..
THANK YOU.
If it was completely clean I would send it back to Motorola for repair. It is the safest and best solution

Actually I can't do it. At the end of March I'll moving to another country.. so I'd like to try any solution to try to fix it now. As the last solution I'll try to repair it in that country.. but for now, you know, i'd like to try other options! I'm not sure yet that the phone is totally ****ed up! So my hope is still alive! ^^'

You could try another cord and/or charger if you have any laying about. That would be on the assumption that it ran down overnight. BTW, if it is completely dead, it may take a little before you get any indication of charging.
have seen it happen several times.
This fixes most of the time
In the unlikely event that your device becomes unresponsive, frozen, blank or black screen, or will not respond to the power button, you can perform a force restart or reboot on the device by following the steps below.
Press and hold the Power button for 7 - 10 seconds, the device will restart and go through the boot-up sequence.
Notes:
The forced restart or reboot will not delete any Data on your phone.
If completing the 7-10 second Reset does not recover normal functionality of the device, then press and hold the Power Button for a full 120 seconds while connected to a charger.

Yep!!! My Pc installed some drivers with success, but I can't see the storage in "My PC" section of Windows. (the led turns on also in this case for 10/20 secs).
But I tried to press the power button, also in combination with VOL DOWN, and it still doesn't make any effect.

[Q] Unlocking bootloader hard bricked my moto x

So....
I think I hard bricked my 1st gen moto x. I was in the process of unlocking the bootloader using motorolla's guide and everything was going fine. i had the "unlock..." (or "unlocked..." i forget what it actually said) showing on my screen and just out of habit, i hit the power button as i put the phone down.
now, nothing.
nothing at all. no recovery mode, no nothing. does anyone have any suggestions? i've tried holding down power and vol down for 5 min. i've tried pushing random buttons. i've tried praying to the motorolla gods.
Is your phone the developer edition?

Press and hold the volume down button simultaneously with the power button for about 5 seconds then release. Can you get into bootloader mode?

This sounds like a hardware failure, maybe a battery failure or a charging port failure. Like someone else suggested, try a different charger and see what happens.
Is it still under warranty?

His warranty is void unless it's a dev edition

Depends on the state - in many states in the US, a manufacturer cannot void a warranty if the product failure/defect has nothing to do with why the manufacturer wants to void the warranty.
Since unlocking a bootloader has nothing to do with a battery failure, in those states where the law is as I stated above, Motorola cannot void the warranty. Now the average Joe may not know this and may not know how to sue Motorola if they won't honor the warranty, but if you do know this and do know how to file a small claims case against Motorola, then you would win in those states.
So it is not across the board true that you void your warranty if you unlock your bootloader and don't have a dev ed. It depends on the state and what is wrong with your phone.
Happened once to my Galaxy Nexus, solved with Odin. I don't know if there's such thing for Motorola devices :/
Odin can reconize the phone when powered off, that's why it worked.

Keep it plugged in, if it is totally drained, it will not turn on for a while until it gets charged to a safe level. Then after awhile on the charger, try to get into bootloader mode.

Good point. I have the old gnex. I just always used fastboot. Never read about anyone using Odin the whole time I used it. Always learn something new!
Same thing just happened to me. It was displaying blue "unlock..." then just froze. Absolutely nothing, just a black screen. Can't get into any bootloader or recovery. I really hope this phone is not totally screwed now. Any of you guys have any luck?

Phone bricked - Black screen

Hello everyone, I have a problem with my Mi5.
The device don't respond and the screen is always black, also in fastboot and edl mode (I can recognize the device through cmd). I managed to boot it into both fastboot and EDL mode, MiFlash can recognize it and I flashed from both fastboot and EDL both China and Global firmware 7.5.4 succesfully but the device still won't boot.
The led does not lights up when I charge the phone and the screen is still always black.
The bootloader is unlocked, I tried to flash TWRP and it did it without problem. Then I tried "fastboot boot twrp.img" and it gave me no errors but the screen was still black.
What can I do? Any suggestion is apprecciated and also a paid solution would be ok if there's no other way, I would also be glad to donate to anyone can help me restore the device .
pretty much like my phone last week, stuck in EDL mode. I fixed it by attaching to charger then held power button for one minute
I just tried to hold power button for more than one minute while charging with original charger but nothing happened :c

it seems you are experiencing a "sudden death"...
its pretty famous for xiaomi mi5 and a lot of people have had it on different roms and firmwares... noone knows why it happens...

first link is for the thread that is dealing with this problem...
2nd link is for a person who had this issue and fixed it...
Well, I tried to flash various firmware. China one, Global dev and Global stable but none worked. This night I left it charging and this morning it has a green led blinking. I tried to boot it with power button but it didn't work, the green led become less bright then the stopped blinking.
Now it's still the same as before.
The exact same thing is happening to mine. 3 days ago it turned off with no warning. It's strange that it's all happening at once.
Discharging and recharging doesn't help. I tried that first. i've managed to get my pc to recognise the phone finally by using the test point method to put it into EDL, but like you, i just keep getting errors when i try and flash

Try Combinations
I'm trying different combinations to turn on the phone it works every time but its totally harassing.
Force Xiaomi Mi 5 to reboot
If the display screen stays black, the trouble often resolves with a forced reboot . To get this done, you will need to press several keys simultaneously. You need to remain at least 10 seconds for the forced reboot to run. The key combination depends upon the versions but had to be one of the subsequent:
low volume + power button
low volume + power button + cough Home
high volume + power button
volume top + touch power + cough Home
touch power + cough Home

Razer phone 2

Hello everyone, guys have the opportunity to restore the brick? I have RP2 devices.
Are you able to get into fastboot mode, by holding volume down button while switching the phone on?
nothing happens, where it doesn’t enter and the screen does not light up does not even charge. (((
Are you sure, it itsn't freezing in android? Check: Hold Vol+ and Power for 10 seconds.
Yes, I already tried to hold for 10 seconds, and even 5 minutes does not help the phone as if nothing had died.
what else should I do please tell me there are still options to restore?
If you've tried both method above, then there's pretty much nothing else you can do to revive this phone.
It does look nice as a paper weight though. /s
