mi 9t pro not responding - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

Hi guys,
Im very new to forums and i really need your help.
I had problem with my mi 9t pro before, he was restarting from time to time, showing some errors (applications stoped working)
Usually restart fix it and hes working again for 1-2 days and so on.
Today when i woke up phone stayed in black screen. Tried to power button doesnt respond, also tried to power button + volume down button for hard reset it also doesnt respond. Then i thought mb its the battery bug, ive put him to charge for few hours, but still nothing, phone doesnt even show battery charging light.
Do you have any advice on what i can do? I would gladly follow any of ur guides.
Thanks for ur responses and sorry for bad english.

i had very similiar problem to that, although someday when i woke up and grabbed my phone it did respond however touchscreen was not(i never dropped my phone or anything). Its a hardware problem and u have to rely on a service

what did you do *before* your diamond stopped turning on?? unless you had a completely unpredicted system meltdown of your diamond for injecting it with super high voltage. it is rare for it to not power off unless you did something ... so please elaborate so we can assist better.
Ok, yesterday i use the phone like anothe normal day, in the night i turn off the phone, and in the morning, when i tried to turn on, i have this problem, for example, when a tried to do a soft, hard reset, the screen is in black, when a conect the phone to the usb the screen is black, is, i left the phone alone, in 3 minutes the black screen again, i don´t know why.
any LED activity when plugged into USB?
I think it is a major manufacture problem
I had the same problem, taking out the battery waiting a while and inserting it back, will solve the problem for some time but it will happen again.
Finally I sent it to the HTC support center.
I don't understand why HTC didn't recall.
If you'll search this forum you'll see the same problem in different stages, some times it's a blank screen but the phone will ring and some are just freeze.
Hi, I've had my Diamond for about a month soon and it started earlier this week by not wanting to come on at all. Been taking out the battery for a few days but eventually got fed up and did a hardware reset tonight. Not long after that it just suddenly turned itself off and I couldn't get it back on again. I thought I'd pack it back into the box it came in and send it back tomorrow and took out the sim card. After that it came to life again.
Happened to get a call after that and that call was suddenly disconnected without any reason.
So I am not very happy with this phone at the moment. Would appreciate any advice or if you know for sure it can't be sorted maybe I should send it back and ask for another one?

Nothing, but one time the pc detect the phone, but later nothing.
No Led activity either on mine when it went dead.
When the Phone goes dead, try cooling the phone down as much as possible, and try starting it up again.....
There is a problem with the HTC Diamond in that it can cook itself (excessive heat), due to the auto over temp function crashing and not switching off the phone..... (That's what I have been told at least...)
I know over around 5 Diamonds so far that have had this issue, where the symptoms slowly get worse...
Have a look at this thread....

PLEASE P.M. me if you have any of the symptoms described in the thread...
I have been TRYING to get my Diamond fixed under warranty now for 2 months with little success... And I kinda need to know how wide spread this problem is to proceed any further.
could not turn on after blank screen ...
Hello,
I've had the same issue as rmorera, and after I hard reseted the phone all went o.k.. BUT after I reinstalled part of the small apps I use, the phone started to go off again. So, the problem seems to be in the software ...
I believe the cause might be the SRS WOW which I use. I installed the .cab, then the .reg file provided (ufortunatelly I don't remember from which thread I got the files ...). And shortly after, the phone stopped working. I uninstalled the software, and now it works! Could it be that the SRS WoW did this?
I tried to reinstall the SRS WoW and I found that if enabled for "Internal (Stereo)" instead of "Headphones" it gets my phone shut when the WM blanks the screen. If I select the "Headphones" options the issue seems to disappear.
Still, the SRS WoW damages the volume buttons action, but I think this issue is on another thread ...

HTC Touch Diamond won't turn on

Hello, I know there are many posts about dead Diamonds but I think my situation is different. I went to sleep one night and left my HTC to charge from my PC's USB. It was charging correctly because I noticed the light around the center button. All good. When I woke up, the charging light was still present and I unplugged the phone from the USB and the light was still surrounding the center button. The screen wouldn't turn on so I had to remove the battery. After I removed the battery and place it again in my HTC, it didn't want to turn on... I have tried to recharge it but the light doesn't flash anymore.. Not on my 220 socket, not on USB... I have a ROM found on this forum and been using it for 8 months with no problem... I just found my HTC froze at the charging step and removed the battery. After that it just won't start... I have managed two times to power on the device by it's normal power button but when it gets to the home screen, it freezes and I have to remove the battery again. It's been 7 days now and I can't power on once... Do you have any idea what happened ?
Thank you
If it keeps freezing at the home screen you are going to have to do a hard
re-set to unlock it. My Diamond froze at the home screen once when it was
new. I did a hard reset and it was fine after that. You will lose your data.

[Q] htc one won't turn on

so i had this phone for almost a year now, yesterday when the battery is about 30%, it freeze while i was opening a word document and gallery in the background. I pressed the home button a while and it still freeze, then i pressed the power button and the screen goes off.. sadly until now.
i have tried so many combinations of power+volume(up down and both) for more than a minute, but nothing works. it even didnt recognize the hard reset combination damnn, and the trick about light sensor also didnt help. I've tried to charge it, with two different cable on a few socket but the led didnt even work. Im so desperate, if i hit the service center it'll be repaired well but i cant imagine all my data would be erased again (about 2 months earlier i fixed the pink tint issue and lost everything). Should i just wait for a few days and keep trying ?? someone having the same kind of problem ?? help me please...

sound like an hardware issue to me (phone freeze then can't be turned on again)

Probably time to send it for repair, looks like you already have tried everything we are suggesting to do normally.

So you did not learn anything from your last experience? Always backup your data on a regular basis! When something goes wrong, its to late to do a backup. Backing-up once a week is a good practice and in case of a failure of your device, data lost should be minimal.

Power Button stopped working properly

Hello, my power button stopped functioning properly after my device lost connection with my phone several times. Since then my power button doesn't react when pressed. However, long press works 50% of the time, so I can turn it on/off, but I can't double press the button to open an app or turn off the screen for instance. It's really strange. I haven't dropped or physically damaged the watch. I tried hard resetting it 3 times, but that didn't fix the issue. Everything on the watch works apart from the power button. The phone charges perfectly. Any ideas? Do you think this could be caused by a software or mechanical thing?
Any suggestion would be appreciated.
Same here
I got the exact same problem , I'm running on the last version of the Null_ Rom and my phone is a GalaxyS3 LTE (4G) with a custom official rom of 4.4.4 ( working with gear manager ).
I don't understand pls help
Hey, Has I said few weeks ago, I had the same problem has you, so I tried to change the motherboard, so I bought a new one one IFixIt and I just get it this morning, but when I tried to change the MB I get a little surprise, in fact the screen or the mother board have been flowed on the other one, I don't really understand what the hell happened in this watch but Screen and MB was sticky as fu**, so I'm just gonna try to change the screen, I let you know if it's work again for me in a week or two ( I'm living in France so It would be about 1 or 2 weeks shipping as the MB )
Hey, so today I just changed my screen and the Gear is working now !
So it seem that was a screen problem :silly:

[HELP] Black screen randomly, have to hold power button to restart

Hi
So my phone has randomly started to die about once every other day. Screen goes black (i have always on screen) and no response from any of the buttons (power button, twice volume down button for camera). I have to hold the power button until it restarts/starts (don't know if it is dead or not). Anyone else has this issue? Only wierd apps that i havent hade before is blockada.

Troubleshoot it.
Delete the app and see if it still happens. If it does, flash a raw firmware and completely wipe your device. if it still continues, its a hardware issue and you should exchange the device.

You're in custom or stock rom?
Im on stock with no modifications.
Phone auto shuts down
Did you find any solution same thing started to happen with me twice in 2 days
The way I fixed it... go to settings, Security & Lock Screen, click on the gear icon next to screen lock, then choose the first option Automatically lock, choose "Immediately" any thing other than that causes the screen to go black. I hope it works!
@Ahmed_x this didnt work for me.
So today i was about to miss my international flight because of this stupid phone deciding to die on me while on charging so no alarm went off.
Wtf is wrong with Asus? How could this have gotten worst with the new update. Are their developers ret**ded?
This phone is being returned unfortunately. Awesome phone but if u cant trust it to give a simple thing as alarm whats the point.
It happened to me twice in three months. The smartphone got stuck/freeze in standby mode: no response from the physical buttons or touch. I use the official android 9 rom.
I managed to restart it with the power button and volume up pressed for 15 seconds.
I hope that with android 10 this will never happen again.
Happened to me today, had to hold volume-down + power for about 10-15s to get it back.
very strange using latest firmware too (WW_Phone-17.0230.2004.60)
[HELP] My ROG Phone always turn off suddenly when charge
Please HELP My ROG Phone 2.
It's been more than a month if the charge will turn off unexpectedly. This situation is experienced until today. So that every time I charge, phone must be in the dead state. I've been very frustrated. Already doing factory data reset, only lasts for one week and back like that again.
Worse, in certain circumstances the handphone suddenly dead and hard to be turned on again. When charging the battery, sometimes the phone likes to not fill. I had to unplug and re-plug the charging cable to return it to normal. Its sucks. I bought this phone in a new condition with the official warranty on January. I already did update to Android 10 when available by the system. This issue occurs after the update.
I had thought the charger that I got from the factory was problematic, until I decided to buy a new charger with the original quality with 30watt power. But it turns out the same.
Same here my phone will turn off while charging. And it will keep rebooting. Sometimes my rog will not charge
My ASUS ROG2 is starting ti piss me iff noe.. Everything I play BR in CODM alwaiz black out..every single game black out. This is not good...Is this normal? Every game has to black out?...
