Help my phone won't turn on - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

Hi,
This morning I woke up, my phone was locked on the screensaver, nothing was happening at all. So I har shut it down by keeping the power button pressed.
Since then, I can't turn it on anymore and it does basically nothing. I tried a hard reboot with power button and volume down (and tried also with volume up or both at the same time).
I also tried to plug it in the charger or in the computer but nothing happen at all.
I don't understand, it was working perfectly fine, I have no idea about what to do.
Thanks for any help.

Does it load the miui logo or it doesn't even light up at all?
If it doesn't turn on at all, then that has got to be a hardware issue and you gotta go for repair, if it does load the miui logo, then I can try and help you

My moto g (2014) wont power on.

I was checking my whatsapp today and all of a sudden the screen went blank. The power and volume button didnt respond. I then tried a soft reset by holding the power and volume up keys together. I did get upto the motorola logo during power on, then the screen turns off and then turns on again with the moto logo. This happened time and again. I then tried a hard reset using the recovery by pressing the power and volume down. I then pressed factory thinking a factory reset would help, again the screen turned off and i got a blinking led for a few minutes. Now i am a working professional and dont find time to take it to the service centre. Was wondering if any of you could be of help. Thanks.

Hello there,
MOstly your battery must have drain so just recharge ur battery and try powering it on. If this didnt help please elaborate your problem by telling did u tried doing something such as trying to root or trying to install a custom room.

[Q] Xperia Z c6603 not booting

Hey guys,
Havent been here in a long time... Well let me start from the beggining, i hope it wont be too long. I unlocked and rooted a phone a while ago (i think its irellevant), and had been using it since the without messing with anything but usual root stuff(lucky patcher, busybox, auto clicker and such). Today, i dropped it and after that it shut off, coudnt turn it on... I think it had a live vertically once that i was trying to boot it today, but it was sunlight so i am not sure.... When i try to turn it on it vibrates once. When i connect it to the charger it doesn't charge or light up the led. The screen is black all the time so no signs there. When i hold vol up+power it vibrates once and when i hold it for more time it vibrates three times, as it should but nothing comes up. But when i connect the charger, and hold vol up + power it vibrates and lights up red led. Then it stays on even when i disconnect the phone from charger.
I connected the phone to Sony Emma, and flashed KitKat build 10.5.1.A.0.292 but once again after it flashed nothing happened.
And i have also opened the phone back and checked the connections to the board, and they all seem to be fine ...
Should i bury it or is there something else i can do?
Anyone has any ideas ? i somehow managed to get to fastboot and flash mode and tried to flash recovery, custom rom, stock rom (with flashtool)... Nothing seems to work ...

Xperia Z... freeze and brick?

Hey there,
So today I was using my Xperia Z aaaand bam, phone "died".
Battery was at that time 70%, phone was a little bit hot, but in scale of 1 to 10 it was like 6. I had not problems previously with it (besides broken screen that got replaced 3 weeks ago). I was playing a game then suddenly it got closed and my screen got shifted. Like Animation of horizontal menu stucked while going to vertical. I pressed power button many times, I've keept holding it for a short time, long time... nothing. Phone did not respond at all. After 10 minutes it went black. No idea if it went "sleep" or so since power button do not work again.
I tried to reset it with Power + Volume down, Power + Volume up and again, nothing.
I've tried factory reset with Sony Companion but no luck either. Phone is NOT detected by that program.
However, when I plug the phone to PC I hear sound that some device has been found. Phone is presented now as QHSUSB_DLOAD in device manager. I've heard that not a good sign...
When I plug it to PC or Charger nothing happens so I have no idea if phone is getting charged or not.
What even more confusing, when I press power button - nothing, phone is COLD. But when I press Power + Volume down after a while it starts to get warm, after a long time of repeating this really warm.
Any ideas what could I do?
Thanks!

You phone has locked or unlocked bootloader? If unlocked, give a try to enter Fastboot mode and flash any custom ROM

Can you phone enter flashmode ? Does any LED indicator shows up when holding Volume +/- whilst connecting cable in PC (USB)?

Randomly will not work. Black screen after boot, phone really hot.

Phone is completely stock. Haven't messed with it at all. My phone died around 5% battery left so I went to put it on charger. Charged it up for like 20 minutes while I watched a movie, and i went to turn it on and it was really hot. It booted up still but whenever it was done booting, the screen just went black. Nothing would work. If i hold power button down, the power down option appears and it works to shut it off. If i shake it, the camera comes up but I cannot take a picture or do anything. Any idea? I also tried to reboot into recovery and couldn't . I dont know if im not pressing the correct buttons so if you know the correct way please let me know.

To get into fastboot mode you have to turn the phone off. Hold the power and volume down buttons for about 10 seconds then release just the power button.
As far as a solution, this issue has happened before. Everybody says that it happens when their battery dies. I am sorry to say that the only solution that works is a factory reset which erases the data partition on the phone.

Phone stuck on boot loop and won't turn on

Phone got frozen while in Messenger, suddenly turned off and now it's stuck on boot loop. Holding volume down and power button does nothing, keeps it on boot loop. When I put it on charging, it heats up, but the charging logo does not show.
Anyone got any clue what might be the problem or how to solve it?
did you receive any pictures via messenger ? that used to be a thing that messed up phones because of one colour outside most phones RGB range.
a bootloop is a cycle, catch it at the right time and you can boot into recovery to clear cache and dalvik.
remember recovery and download mode need the cable plugged into a USB device to nowadays.
the instant the screen goes off hold volume up and power and then plug the cable into the phone (the other end already being in the PC).
if you did receive a file before your problem that'll still be there and the problem might persist. you might need to boot up into safe mode and delete something.
The phone got frozen at the main screen of Messenger, haven't received any messages or pics.
The thing I haven't mentioned but dk if it means anything, sometimes it gets to the Samsung logo, but then it goes off and turns back on.
Tried to hold volume up and power button couple of times, sometimes it would do a strong vibration and then do nothing, but I'll keep on trying.
Thanks for ur help

don't forget the USB cable, you can't manually boot recovery without it.

if you don't mind losing messages next time you could try clearing data on the messages app. you'd need to be pretty quick by the sound of it.
