Question phone wont turn on, need help - Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40

i was playing a mobile game that has high graphics, when my phone started to showing network private dns not being found error message. also started having a bit of wifi issues, had to reboot to fix it
5min later screen freezes during gameplay and turns black. couldn't do anything. i had to reboot it, but the same thing kept happening over and over again for while. until the last reboot, above the poco logo boot-screen a thick static line showed up and instead of going into the homescreen it stayed black.
can't seem to charge it either, when i connect a usb i don't hear any sounds. what happened? why is this happening
P.S. battery was still high if this needs to be known info, was wired to my pc. also didn't do any updates either.
edit: there are times i hear the boot up jingle when pressing powerbutton, but thats it
edit 2: can connect with usb (hear jingle), but screen is still black

but can you reboot to recovery or bootloader, by holding the right buttons when rebooting. (recovery power + volume up. release power when screen on. bootloader same story but volume down).
The usb port and the display cable are really close to each other. maybe because you kept the usb plugged in while gaming, you created some sort of movement and partly disconnected the display cable.

maybe just maybe your screen going bad because over heat try to call your phone if you could hear the sound yep sounds like your get bad screen and need replacement

Means hardware issue - take it to service center obviously.
I'm almost 100% sure it isnot software

i heard that the f3 has overheating issues, is this true?
i still have my warranty, can i use it to fix this issue for free

It does - phone is garbage imo. Unless u lucked out and got unlocked version of GPU ( Search konabess 870 ) I'd probably sell it / swap it for some 865 device.
Something like mi 10t pro can do 20hours screen on time with right tweaks
First take it for repair - this is hardware issue that they need to fix under Warranty - then figure out what you wanna do with it

it happen to me when trying some pixel oriented roms. the phone itself can charge but the screen always dark, you might be able to feel slight warn on the back. yes its hardware and I change the whole motherboard freely on xiaomi service center

if it doesnt turn on anymore that could be becuz of overheating were you using performance mode? if you hear a sound and/or if you can go into recovery its likely the screen has been damaged or its the display port or ribbon

well it doesn't turn on anymore, very rarely i feel it vibrate so i guess hardware issue?
i was playing on normal mode, didn't switch anything.
also if the motherboard is fried, does that mean my data is losted

if you feel it vibrate then its probably the screen better take it to a repair shop if you have warranty but dont let them give you a new phone or you'll lose your data
tell them to keep your data

what if its hardware? is my data gone?

depends on the part of the phone if its the motherboard your data is likely to not be restored by the average repair shop

[Q] s4 shuts down seconds after powering on

I left my perfectly fine i-9505 s4 to charge overnight to find out it did not respond to anything, holding down the power button or power+voldown+home did not result in any sound image or vibration.
Removing the battery and re-inserting it makes the s4 respond to the power button, but the phone shuts down seconds after powering on. This also happens when I try to enter recovery, download mode or insert the charger.
It even happens when I use my usb JIG, the downloading screen appears for a second, after that the screen blacks out again. Tried removing the SD / SIM cards.
The only way I can connect it to Odin for a second (at least as far as I know), is by:
1) removing battery,
2) inserting Jtag
3) inserting battery
4) remove JIG (very quickly)
5) insert USB to PC (very quickly)
Yay! Windows makes the "USB connection" sound, before making the "USB connection lost" sound a second later and the screen blacking out..
What could cause this? Is it my battery? Connector? Software (jamals 4.4v6, faux123, mj5 modem)?
Have you tried directly plugging it into the charger or your computer without the battery?

Thanks for your reply.
Yes, I did try that, the screen does not turn on if I plug my charger / USB cable from PC into my S4 when the battery is removed.
What could cause shutdowns after 2 seconds from booting? I hope this is fixable!
It sounds like there is a physical defect in the device. If it was software related (this can be caused by a borked up ROM or Kernel) you wouldn't see the same behaivor in Download mode and that doesnt' use either the ROM or Kernel.
You could have something physically broken inside the unit that is causing an electrical short once something common to the system and download mode is activated, which would cause the reboot. That could be the USB port that both the system and Download mode will constantly poll the USB port looking for a connection, but only after a second or two. It won't look at the USB port immediately when teh GALAXY S4 splash screen pops up so that's why you get a second of it working. There are 100 other things internally that it could be too.
I'd say make sure the charing port is cleared of any debris. If that doesn't work, I'd say it's broken and needs to be repaired. Without knowing exactly what is causing the issue I wouldn't suggest trying to fix it because you'll cancel the warrenty by doign so and might not find the problem. It could even be a faulty memory chip on teh circuit board that wouldn't look broken to the eye.
Since you can use Download mode for more than a second, you obviously can't try to restore to stock, which is the prefered go to method to fix things like this.

Sounds very much like a hardware malfunction. Without having the device on hand, I can be of no help, unfortunately. If it's under warranty, I suggest you try to get a replacement.
Thanks for the replies. You have convinced me that this is a hardware issue. I have no clue as to what might have caused this defect.
I will soon try a different battery, and if that fails I will contact Samsung.
Unfortunately though, my firmware is custom and this may void warranty, which would suck since the cause of the issue is probably not related to the software.
A day later, the problem appears to have solved itself. I'll keep you updated.
My S4 was working for some time, but the problem returned, the phone shuts down seconds after booting (normal boot / recovery / download mode / USB-Jig induced download mode..)
HOWEVER:
Sometimes, when I connect my S4 to a charger, it turns itself on (first displaying the charging icon) and then starts booting, showing the Google boot animation (since I'm running GPE). This animation keeps going for minutes, and then the phone shuts down again (black screen, does not respond to anything.

You're just delaying the (possibly inevitable) death of your phone. Use your warranty while you still have it. At least I would in your situation.

The symptoms that you have described are those of a bad power button. This happens quite often.

I think you are right! It would explain the inconsistency and the fact that my phone sometimes turned on by itself.

I had to send my S4 back to Samsung THREE TIMES before they realised it was a hardware error. The first two times, all I got was a factory reset.. Which of course, didn't help.
I'm pretty sure you were right, it was a bad power button.

[Q] Screen wont turn on

I have the new Galaxy Note 2014 edition tablet, as does my son. My son came home today with his tablet and told me the screen no longer turns on. He said he was playing a game with a friend when the screen flickered and then went dark. Nothing seems to bring it back online.
Tried to press the power button and volume up button for a forced reboot. Most times does not but it did reboot once and stayed black.
Also tried pressing the power button down while pressing a finger on the screen, apparently a solution to sleep of death or something. I can't tell if that does anything - if anything it seems to turn it off or something because it has become unresponsive after doing that.
Any thoughts on what to do next?

I seem to be able to get it into two states right now, but neither is like it was - powered on and "working" but no screen. If I hold the power button for a while it seems ot go into a deep state of sleep or off, but I do not quite think it is off. If I hold it again for 30 seconds nothing happens at all. If I hold it again for 4 seconds, the back and menu soft keys will light up again. And then I can get them to light by hitting the home button or a quick touch of the power button.
Press and hold power in either state while holding volume up no longer seems to take me to a reboot - I no longer hear the power up music.
No idea what state it really is in or how to get it out of this.
ok - I think when it is able to light the buttons - it actually is still on. I just heard the vibration notification of an incoming alert (email, twitter or something).

Use the function to chat with the amazon support.
just google "Amazon Support". You will find the option on the right side on the amazon page
They will know what to do and from my experience amazon will offer you that you can send your tablet either to amazon or directly to samsung and they wil pay the shipping costs good luck !

If you are within your refund stage then get it exchanged for a brand new device if not then yeah you will be covered under warrenty.
Its a problem with your tablet. I know of a few other people in other threads who have also experienced this. My experience was different though because mine didn't turn on out of the box. I think there's a problem with Samsung's display connector. Your best bet is to just get it replaced at this point.

Yeah - it looks like that. I was hoping for a service option because my son has a lot of homework on it that would be nice to retrieve and of course he is bummed that he might lose all his game stats. I tried ot hook the device up to the pc to see if I could copy some files but although the device shows, its internal drives do not show up.
I really do not know what state the device is in right now. The soft buttons light up and if i pull the smart pen out it vibrates as it acknowledges it has been taken out, and I can hear the occasional vibration notification as an email, twitter update, or some other notification comes in. So - it "seems" like it is on. But I can not get it to do a forced boot and a few other things seem not quite right.
Anyway - Thanks for the help everyone!

That's strange that you can't see the drives when connected to the computer. If you look really closely though it could just be the backlight not turning on when the actual lcd is turning on. If you really need to see whats on the screen and try to find a way to send the files to yourself or upload them somewhere you can try taking a screenshot while the tablet is connected to the computer and check the screenshots folder to see what is on the screen at a certain time. I know it could take a while, but if what's on the tablet is really important it could work. Best of luck.

I tried to see if there was anything vaguely showing but the screen is totally black as far as I can see. I have a service ticket open with Samsung and will send it back for repairs. I would prefer repair over replacement as I would hate to lose all the stuff installed. I generally trust repairs as my philosophy is that they tend to pay better attention on the repair than the assembly line.
Thanks for all the help everyone!
You should definitely try getting it repaired or see if it's possible to copy the data to an external storage prior to getting a new one.
As a general rule I always have Google Drive take automatic backups and store what I can on my external SD to prevent any loss of important work.

Don't you have to unlock the device for the drives to show up on the PC? It's probably waiting for the lock screen to be cleared.

This is what I am thinking - that it is sitting at the lock screen. I tried to see if I could unlock it by touching the screen in the right places but I guess when the screen is dark its not just dark but not functional. I figured as much but thought I would try anyway.

Well - its going back this morning for either repair or replacement. I would prefer repair to save the apps and data and work. Nothing irreplaceable but its a royal pain to reset all this up and my son had significant game experience on the device that might be nice to save.
Either way - it will just be nice to get it working.
Just wanted to follow up with the results. Got notification from Samsung yesterday that they repaired my device and it is on its way back. They replaced the LCD screen and the battery. All free and in warranty and coming back 2 day air.
Not sure why they replaced the battery. I wonder if the battery takes a beating because of 1 game that we play - Bloons TD5. It tends to drain the battery from full to empty in about 30 - 45 minutes. Any other game or function we do the battery last many hours. I wonder if that damages the battery long term?

Is my 1+3 dead!?

Hi everyone,
I'm experiencing pretty silly situation with my phone.
So the story begins here:
I was surfing the web while listening to music in the bus when suddenly my oneplus3 randomly turned off and I couldn't turn it back on. (I was on something around 15% on battery so it's not a low battery problem) I tried to turn it on several times and after holding the power button for like 10secs it turned on, and after pressing the power button again (because I needed to get past unlocked bootloader screen and dm-verity) I saw a boot screen. The capacitive button leds turned on and after 3 secs it turned off again, so I started worrying... After a while I tried to access the recovery, but no luck at all. It powers it self off after bootscreen. So I started to research. Tried to flash the entire OS, partritions with msmdownload tool. After several unsuccessful flashes (firehosewritedata failed sometimes while writing userimg or system.img or boot.img) I did get the download complete green text message, and after successful flash, the white LED turned on, even the phone was not plugged in USB or charger and turned off. The screen is completely black and the white led just flashes constantly without blinking or anything. I could only turn the led off by pressing the power button for another 10 secs. And after turning the phone off, problem still remains. After oneplus logo phone shuts down...
I can access bootloader.
And after flashing everything should be on stock, because now I only got screen only about bootloader, no dm-verity..
And of course - I still cannot access the recovery.
p.s. I tried to do the power cycle (as the tech support told me) but still no luck at all.
did u tried the full msmdownload tool (1gb) or the 55mb version ?

Follow method 2 from the Hard Brick guide by Naman Bhalla and try two or three times.
Sometimes it takes more than once for restoration.
Since you opened the phone, i think your warranty is gone now.
If the msmdownloadtool didnt help you, there is nothing you can do i think.
try to flash again, and if it still maybe something short inside.
if you have disassembly your phone, try disconnecting various flex cable like camera, sim slot etc that connect to the mainboard, that doesn't prevent device from powered on, then try to turning it on.
if it still, check your mainboard, if you don't know how, send it back.

Is ir really gone? There is a still warranty void sticker on the screw there, but of course it's possible to see by eye that the phone has been opened.
I have an appointment with Level2 tech support @oneplus, they are going to remotely flash the entire OS, but do you think they are using pretty similar technique as the msmdownloadtool?

What about battery? Charged?

Yes battery is charged of course. It's just doint the same thing. Turns on, after a while when bootscreen comes it just turns off and white notification led appears, after that nothing.
I tried to flash it with tool using method 2 for like 15 times with "download complete" messages, but still no luck at all. Tried to erase partritions with fastboot, flashing just only recovery, modded recovery etc. but I still cannot access the recovery nor system. I just don't get it why the phone does not boot into recovery if I flash it or boot it straight away, It just only turns off and that's it. nothing more. Only black screen and white led lighting all the time (after a while the phone turns warm).
I have read all the MsmDownloadTool thread in "Mega Unbrick thread" and saw that few people have experienced the very same situation as me, so I was wondering if there is any fix for this? It's so strange that I was just surfing the Web and it just turned off by it self with like static image for miliseconds and after that just black screen.
There should be any fix. I guess that it's just a partition error...
Ok, not good news. I had a little remote session before a while. They says it's already a hardware problem.

Pfffft you think manufacturers notice when you take apart phones? Hell I took apart my Xperia Z2 because it was having problems and then glued it back together with cyanoacrylate hahahaha (worst thing to do but wtv) and no one noticed though it was seemless and everything looked perfect
Guys, I've got something for you! Not really the same thing as Naman.
p.s. not saying its original hehehehe keep safe
man i got a very similiar problem but my op3 has a black screen i was also on low battery around 5-15% when my phone went off after i was in twrp
Actually I was on twrp too! Also I have recently noticed that recovery loading speed was far too long than normal one. I'm talking for something about 5-7 minutes after reboot into twrp. So, who knows what did happen. Just made an RMA request. Will see how it goes.
Anyway, I was on stock 7.1.1 and it's just rooted with custom recovery and that's it! Nothing more! Is that just a factory failure or maybe it's caused by drops i have had? Nothing serious for a 4-5 times for a half year. Of course I have used it even in winter when the snowflakes are coming down from the sky and little rain. Btw, these liquid indicators are white, so all safe. ::laugh:

My S4 mini won't turn on, doesn't vibrate, can't launch recovery or download

So a few hours back I picked up my phone, but it didn't respond. A few minutes earlier it worked fine, and now it just seems dead. I cannot launch recovery mode or download mode. The phone does not respond to me holding the power button or something, there is no vibration and no visuals on the screen. Removing the battery and plugging it back in does not work. Leaving it charge for a while does not work. (assuming that it even charges). When I plug in the phone into my PC via cable I hear a sound that something is connected, but it doesn't show up on 'My PC'.
What do I do?
The same happened to my sister! Nothing worked, probably the motherboard died. Used it at leaset for spare parts for my other s4 mini. Especially the LED panel is so precious, it's cost is like half the price of the phone.

Yeah, likely. I ain't a geek or sth, but the same happened to my sister. Was looking for a solution for hours, but it's probably some random variation in voltage or sth that burns some part on it and then it dies. You don't have to crack the phone etc., it can happen randomly.

Wouldn't a broken motherboard make my PC unable to make a sound when it's connected? Also, when it's connected to the PC and i hold the power button for ~15 seconds, it disconnects. This would mean that the power button still functions

Then it's deffinitely NOT completely broken. A dead MB would definitely NOT identify the phone in the PC.
Did u try entering Download mode & connecting to ODIN, trying to load FW again?

I cannot enter any mode. Pressing volume up or down + home + power doesnt do anything. How do I connect to Odin, and whats an FW?

FW = Firm Ware i.e. software that is flashed onto chips. aka ROM.
But if you can't go to download mode you can't flash stock ROM again. So Yes sounds likely some component has failed or maybe just a bad solder joint, a short, etc) which is not allowing power up,( either way you need someone to fix hardware & install stock using jtag for you, probably not worth the cost on our old phones in most countries. but if you can buy a used phone with eg a damaged screen or other problem you may be able to get 1 working phone by swapping parts eg power board ...
The same happened to me last august... I posted here, but no one ever helped me https://forum.xda-developers.com/galaxy-s4-mini/help/weird-bricked-gt-i9195-stuck-black-t3619023 i just think that it's some kind of programmed obsolescence, my phone was 4 years old and it just shut off and never light up again after closing a simple call... F*** Sammy and their timers!
Just happened my nephews phone. Was intermittently responding to buttons and now not at all. PC detects it and shows as "HS-USB Diagnostics 9008" in Device Manager.
There are a couple of guides online for using applications on the PC to interact with the phone using this device ID, but it seems to be mainly focused on LG phones. Anyone know if there's anything that can be done for Samsung devices?
The exact thing happend to my S4, it suddenly turnd of while im using it, did anyone find a solution?

Replaced battery, phone charges but won't react to buttons

My phone's battery was almost dead, so I bought a replacement battery and installed it. Nothing weird happened during the "procedure", and the battery charges fine, but the phone won't boot. The screen lights up to show the % when I connect it, but after it's off, it won't light up again when I press the power button.
I'm guessing something happened to the cable that connects the buttons to the MB. Or could it be something else?

Impossible to know what has happened as we didn't see the repair.
Will the device boot to any partition ?
Recovery ? Download mode ?
I've seen several devices lose the OS if the battery goes completely dead....and pulling the battery would do the same thing on a susceptible device I would think.
Unless you can get into DL mode or recovery....it doesn't look good for restoring the device....g

No, because it won't respond to any button press, so I can't boot it. Is it possible to access adb or something when the device is off? It does show and is identified on my PC when it's connected, so I don't think it's the case that its drives have been wiped.

So the PC is seeing the device but you have no screen activity....
Is there a chance that your display is not connected ?
I'm reaching here....but with all of the connections inside of the device....you may have missed something ?

The screen turn on fine when I first connect it and it starts charging, but I can't turn it on. I send to a repair shop and they diagnosed that the power button is not getting any juice, so I ordered a replacement for it, I just hope the issue on the cable and not on the connector in the MB.
