Xiaomi Mi 9t completely dead(?) - Redmi K20 / Xiaomi Mi 9T Questions & Answers

Last night I've put my Mi 9t to charge and went to sleep. When I woke up, the phone was turned off.
I've tried to restart it and also pressed the volume + power button combinations to force the recovery mode - unsuccessfully.
No blinking lights, no MIUI entry, no vibration, zero response from the phone. (Is it bricked?)
I've started to research and since my computer can't find the Mi 9t (running Windows 10) the only solution seems that to disassemble it and do the EDL Mode Test Point, to acess the recovery mode and try to flash the phone.
Do you have other sugestions to try?

This is weird. Maybe it's not charged? Did you try another charger and/or cable? How can the phone get bricked overnight by doing nothing? Never heard of it.

I've tried today during all day with a different charger, no response.
It's the first time a thing like this happened to me as well. I've never flashed it before or did any major modifications. I was running MIUI 11 still.
If the battery runned out how can I revive it?
On another forum a user told me it could be the integrated circuit broken or a battery problem.

Then I really don't know. Like I've said, never encountered this before. You could try going to a repair service.

you could open backcover and charge battery directly to see if thats usb problem

You can make an EDL cable. is very easy to do and you have a lot of videos and pictures about it.
Dont worry if you have to open the phone is really really easy. With a hot air gun or a hair dryer you can do it in 2 minutes. You are going to need also a piece of radiography to separate the cover
Then the test point is really easy to do it, check some pictures in google, also you can check the usb port if it is damaged or not once the phone is opened, but of course if the phone stoped working from day to night is weird a usb faulty port

Pls don't open anything or try an trick. Just take it to a repair service so u don't make things worse

I've tried the test point and didn't work, as well
So I took it to a repair shop that accepts xiaomi. They are going to order a new battery and a battery connector (2-3 Weeks).
I'll post when I'll get more updates.

I had a lg g3 that did the same thing. Charged it over night and it didn't work the next morning, could be power surge. Ever since then I never charge my phone over night

So, I've picked it from the repair shop and they couldn't fix it. They changed the battery, the battery connector and the display. They said they don't have a solution for the phone.
My next step is to contact gearbest to see if they have a solution for me.

Powered OFF unlocked nexus 6p with custom rom -> hardbricked?

Hello everybody,
I have a nexus 6p with unlocked bootloader, twrp, rooted and running the latest resurrection remix rom with a few xposed modules on it (amplify, boot manager, greenify donation ).
It was running like a boss, great performance, great battery life and so on.
Yesterday insted of putting it offline for charging overnight I decided to turning it off, and then I plugged the usb cable and I saw that it detected the charging while it was turning off.
This morning when I went to turn it on, nothing, nada, 0, no sign of life at all. Plug-and unplug the charging cable, no luck, change charging cable, plug it to the pc, nothing.
Tried to push the power button for 10, 15, 30 seconds, no luck, tried to boot to recovery with power button plus volume down, no luck again.
Very sad day got any advice for me?
Thank you!

Sounds hard bricked. Probably an internal malfunction. If you have it plugged in and holding power and volume does nothing, then there is nothing you can do. Very unlucky, sorry. Did you get insurance?

no, i'm not sure what huawei will have to say about my warranty, given the fact that the phone is modded.
I noticed that if I charge it for a very long period of time the top left portion under the screen gets mildly warm... not too sure why but I think that something hardware was faulty.

If you have to deal with Huawei then you are probably SOL. They won't fix anything under warranty. I would just take it to a local repair shop and have them look at it and see if it's something not too spend to fix. You could contact Google though and see if they will help you. Google actually cares about its customers. Huawei does not. If it wont boot they won't notice the mods probably. I got an HTC replaced that I bricked some time ago and they never noticed. If it turns on they might, but that doesn't sound like the case here.

I think that you can count on google support only if you got it through the play store which is not my case.
I took it to official Huawei repair center here in Milan, in approx 7 to 10 days they'll fix it. But I'm afraid they will eventually turn it on and find out all the naughty things that I did to it and **** my warranty
I'll let you know how it goes, thanks for your support.
the problem was 100% hardware, but now I am happy to report that the italian shop where I bought my phone have it replaced but only after 2 months. They said they fixed it but they lied because it is now graphite instead of silver LOL

Unable to boot up, Red light when charging issue

I have been unable to boot up my letv 1s device, I have tried everything listed on this forum and other forum to boot up my letv device. Including removing the battery and reconnect them back again.
Recently, I tried to repair it to local phone repair shop, they told me it needs a battery replacement. I bought the battery from aliexpress and replaced them, but it still doesnt boot up.
The repair shop gave up and gave me back the phone and told me the EMMC is weak (I'm not sure about this).
I disassembly the phones and try to figure out the problem, I am guessing the problem might be with the charging board, I am posting the video here hoping someone pro could help me solve the problem. I'm guessing its the charging board because everytime I connect the device to the PC, it kept reconnecting when I tried to FLash a new ROM.
Here are the video of the board kept reconnecting when I tried to connect them to PC
youtube(dot)com/watch?v=N8PMQej9BQc
youtube(dot)com/watch?v=GfLOrslXYRE
Here is the picture of the charging module board
ae01.alicdn(dot)com/kf/UT810zNXElXXXagOFbXw/Letv-X500-USB-Module-Plug-Charge-Board-Microphone-Module-Flex-Cable-Dock-Connector-For-Letv-1S.jpg_640x640.jpg
I really hope someone with more experience could give me more insight about this, thanks.
PS: Please dont ask me to charge the phone again with original adapter and cable, because thats the first thing I tried and I charge it for more than 24 hours already (I even tried to buy a new adapter and usb type-c cable). Oh and I tried connecting to PC with the battery connected also, and it kept reconnecting.
Hi, I also have same problem, but still no solution.
Hi @casper2201 , @softkans and any one with the same issue,
I too had the same issue. It started with the charging rate becoming too slow (1% increment in 25 minutes of charging). I switched off the phone and left to charge for around 35 hours straight and came to find it 79% charged. Then I tried flashing the LOS14 after LOS13 ROMs but in vain. I also fiddled with the Kernel Adiutor, still no help. The charge won't increase when the phone is on so I left it to discharge until it switched off. Then the main issue showed up with red light always on when charging and blank screen.
I also posted about it here, but no one replied. Then I took a leap of faith and went to a local repair shop. He confirmed that it was a hardware problem and the charging module needs to be replaced. Just now I am coming from the shop itself after picking up my phone. Its working fine till now *fingers crossed*. He charged me ₹1300 ($20) which is a little high for the service but it doesn't matter as he was the only one ready to open it as there was the risk of cracking the screen.
So, summing it up, if you have the same problem as that of mine then you need to replace your charging module and I think it will be fine.
Charging module replaced.
Current condition of phone.
The rubber bands will help the adhesive strengthen.
Thanks,
Abhishek

Yesterday when I was done with setting up my phone, I put it to charge and the same issue has come again. Its not charging and the "Red light of Death" is back. Today I'm going to the repair shop again and see what he can do now.
I think this is the end and there is no point throwing away more money on the device anymore.

Sir same thing happened with me....phone is not charging red light alert and display blank...please suggest me what can I do
I want my data back from that and its not starting my data is really very important I can't loose that
Help me and tell me what can i do so that my data will not loose and my phone starts
Remove display and disconnect battery. If it won't be alive again that's probably power management unit problem and you won't fix that way.

[HELP]Phone Dead

Last night I left my phone charging overnight.Today morning when I woke up phone was working.I opened snapchat and phone got stuck.I gave it some time but the screen turned off after a while and now the phone is dead.No charging animations,no recovery mode,no flashing LEDs,NOTHING !! I have bought phone from 3rd party seller(Flipkart - Google's official sales partner here) coz Google rarely had the phone in stock. Also my 1 year warranty is also over.

Do you mean it won't power on at all? If so, hold the power button only down for 2-3 minutes or until it boots, or not.
If you meant it starts but gets stuck at the Google (no startup animation) and you cannot access recovery mode, that is totally different.
Connect it to a PC and see how it is detected in Device Manager.

I tried holding power button for several minutes. Nothing .
It does not show any signs of life, and its definitely not stuck in a bootloop.
Also got nothing in device manager too , not even EDL 9008 Mode.

Seems like after charging all night, the battery would be full. Never heard of a 6P dying on the spot with a full battery. Were you using a stock charger or aftermarket? Wall charger or something else? I'd put it on a *different* wall charger overnight and try the long power button press again. At least 2 minutes.

Stock charger. The charger works fine as i have checked it with other phones.
Either your charging port is bad in the phone has no juice and died. Or the battery is bad and come morning it died because of the charging all night. Or possibly the power button connection is bad internally maybe broken and can't turn on. I had a bad power button

How did you know it was a bad power button?
I have a similar problem as the OP. If I shut my phone off I can't usually get it started for about a day or 2. I'm starting to think I may have a bad power button as well.
*Edit*
It can't be a bad power button on my unit cause it works flawlessly with the phone on. I'm stumped.

I guess the battery has been dead coz I have faced similar situation with my HTC ONE X+ using it for just a year and the battery got swollen and it's completely dead. I went out to a repair shop nearby and after opening the mobile, the battery was completely swollen and the technician just replaced a new battery and it did boot up and worked fine. So from my experience I guess it's the battery that got damaged completely (dead) and you need to replace the battery. Hope this information is helpful

You couldn't tell the battery was swollen before the phone was opened up? I wasn't aware until recently that this was a potential problem with the 6P but since other people have reported the same I guess it can be added to the list.

My job involves troubleshooting electronics with circuit boards all the way up to 3 phase hv. It's probably likely a power issue which is either the battery, screen, board, switch, or connection. But the most likely are the forementioned.

HELP !!! S7 Edge doesn't turn on (neither on download mode, nor on recovery mode)

So my phone was OK, when suddenly having 42% of battery it turned off and didn't turn on again. I can't access to download or recovery modes to flash it and change the ROM. The phone doesn't react even on charging (0 V, 0 A on the USB cable). Don't know what to do.
Did anybody have this problem too ? I really need to bring back this phone

No, there is nothing. Just bricked phone without any sign of life.
Unfortunately, if that is the case, this may be a hardware problem related to the motherboard which needs to be replaced. Make sure to leave it for a few days then try to charge it to see if it would respond, otherwise, make also sure that this is not a display problem by checking if the device is working ( try phonecalls or so ... )

It is definitely the case. The battery itself gives 3.6 V but the phone is not getting it. I've seen a topic where a guy was advising to perform a JTAG flashing (can be a bootloader error) connecting the phone immediately to a power source (without battery). But not sure if I can perform it too. Any ideas ?
Bootloader errors are mainly due to motherboard malfunctions on the galaxy S7 edge, this is a very common issue where the only fix is to completely replace the motherboard, some cases can be repaired due to a reset or a stock rom flash ( which cannot be your cases because you cannot access to download more nor recovery) while others are fixed with a custom flash. Some very rare cases are also fixed with that JTAG flashing you heard of, this forces the battery to work and deliver its power to the rest of the parts, but this is a very risky operation which can damage your entire phone. If you wanna try it, I advice you to get some professional help as you can hurt yourself too in this process ! Good luck
It looks like you a main board issue. You might need to have that part replaced.

Thanks for the info. Is it possible to replace it with another board from another used phone ? Won't it cause any conflicts with other phone parts ?

Yeah, you just have to make sure that it is completely working. But my experience shows that it doesnt end up really well, because the phone will just suffer from other malfunctions due to imcompatibility and all. So I dont recommend you doing it, if you really want to repair it, send it to the customer services !
Good luck

I had the same issue. As suggested that the phone may switch on once the battery is completely drained, I waited till last night and plugged it in and it started charging.
It was fine till this morning. I inserted the SIM cards and then connected to the laptop. I thought I would backup the data using smart switch before doing a factory reset. The backup went fine till 75% and then boom again turned off. This time there's a lot of battery left, and I might have to wait 4-5 days before it can be drained completely. But I'm now hopeful that it'll eventually turn on and when it does I'll immediately do a factory reset before doing anything else. I'm suspecting that a rogue app might be causing it. This time it might have happened while that app is being backed up. The LED is constant Red this time indicating the state it was connected to the laptop at the time of incident.
Is there anyway to drain battery quickly at this stage?
It turned on again last night when I connected the charger. It was showing the charging symbol. After 5-6 minutes of charge I tried to hold Vol - + Power buttons briefly to reset the device and it went off again. It's lying like a brick currently.

I had the same issue. As suggested that the phone may switch on once the battery is completely drained, I waited till last night and plugged it in and it started charging.
It was fine till this morning. I inserted the SIM cards and then connected to the laptop. I thought I would backup the data using smart switch before doing a factory reset.

had the same thing happen to me.
Initially crashed.
could be turned on after draining the battery(phone was still warm at times with screen off/phone off)
charged and could turn on again.
But the time it could stay on would decrease and decrease.
It then just bootlooped and with that would only accept charge turned off.
In the end I couldnt turn it on at all and it wouldnt charge.
Looking to replace my mainboard now. seems that the Flashmemory damaged itself.

Mi A1 dead, LED blinks on charger, how to revive?

Hi! Similar problems have been posted on the forum before, but none of the solutions worked for me.
Stock Mi A1 with vanilla Oreo (latest official patch), everything stock & vanilla, no hacking, no rooting, no modifications etc whatsoever. All apps installed through google store, nothing fancy.
In short: put my phone into airplane mode about a week ago (battery at 90%), then a few hours into the flight the phone blacked out. Won't react to power button, power+volume up, power+volume down, all buttons, no buttons, any combination of buttons for any length of time. Phone was in my pocket, no physical impact or anything, just "died".
There are 2 signs of life:
- If i plug it to charge the notification LED blinks about 1 / sec
- If I connect it to a computer, it recognizes it as Qualcomm 9008 blabla device.
What I have tried so far and didn't work:
- All imaginable button combinations: no reaction
- Fully charging phone: doesn't help
- Letting battery deplete: doesn't help
- Disassembled the phone, disconnected the battery, put it in charger, reconnected the battery: this fixed the issue for some, didn't work for me.
I GUESS that since the computer recognizes it I could try to "flash" it or whatever, although 1) there are a lot of negative posts about it 2) I have no idea how to do it (which exact ROM, using which exact tool, etc).
I wouldn't mind not losing the data on the phone though, if that is an option: I was about to back up my photos on the flight, but it died before I could have done it.
There is no official Xiaomi support / service where I live, bought the phone while visiting a country which sold it.
Any suggestions?
Small update.
- adb doesn't see the device.
- Miflash sees the device, but dies at "ping via firehose" stage.
-A1 low level backup tool doesn't see the device.
After 2 weeks of googling I have found around 50 forum threads around The Internet with similar issues, but no solution as of yet. Sounds promising!
I had this problem 2 hours ago and fixed with the Disconnect battery, connect charger, reconnect battery (while charger is still connected just to clarify). you tried this fix like this? reconnecting battery while charger is still connected?
Maybe try getting a different battery and connect it, and/or maybe let the battery discharge itself.

Thanks for the replies fellas. I have tried this before. Now I have tried this again just to be sure. Did it multiple times. Disconnect battery, connect charger, reconnect battery. It doesn't alter the phone's state in any way. Doesn't react to buttons, flashes led on charger, shows up as qualcomm 9008 device on PC, but doesn't let me flash anything. Sad.
Qualcomm 9008 is sigh of faulty emmc chip. Bad soldering i guess. Take the device to the service center. My 1 cent op. Regards
Its very simple the solution. The problem is the cable. Try to change the cable, charging the phone and turn it on. I my case works

Have you had any progress? I'm having similar issues with my mi mix 2s.
The answer is to replace the battery. I have two dead batteries for my Mi A1. Both batteries were left in the drawer for several months and upon connecting them to my Mi A1 they showed the dreaded blinking light. After trying to fix this for a day I gave up. I disconnected the battery, the phone booted up right away. Bought a new battery and everything is working again. Hope this helps!
I too had numerous kind of hard bricks with my previous smartphones.
Here are the links that will save your life:

Try the ones that you think fit the most.
I had the same issue just today
removed the battery connector and connected it back without touch any other component
phones working fine now
its bricked and get into edl mode just try to flash with MiFlash tool i have faced this problem some time ago when i flashed an ota with twrp recovery then my phone went dead and when i connect it to pc led blinks and phone recognise in ports as "diagnostic port 9008d" something like that then i install the drivers and flash stock pie rom with MiFlash tool but after successful flashing phone wont boot but after pressing power button for 10 to 15 second phone starts. i have unlocked bootloader so it works for me but i'm not sure it works on locked device try it or use QFIL flash tool from QPST
This happened to me but all i did was charge the phone the whole time.
My Xiaomi A1 had the same issue, I think I have tried all available solution but unfortunately mine still dead, and when I connect the charger it blink.
I guess the ultimate solution is to throw it to a recycle bin.
