Screen has stopped working - help! - Xiaomi Mi MIX Questions & Answers

Hello all,
I have a Xiaomi Mi Mix (256gb) and I haven't changed anything since it came out of the box in March.
This morning, after working fine in the car, the screen stopped working. There are several grey lines at the top of the screen and the notification area is flickering, and I now can’t even unlock the screen. Nothing else will work. I’ve turned it off and on and rebooted multiple times, but this hasn’t done anything. It has never been dropped or thrown about.
Any ideas? I’d like to avoid doing a factory reset, but I’m sure that’ll be my next step (although I’ve no idea how I’ll do that!). I’m a complete novice when it comes to doing anything complicated with phones, so I’m in dire need of help. I’m not desperate to send it back to China!
I really hope someone can help…..

Seems like hardware problem.
But to check if its a software problem you have no other choice than factory reset.

Thanks. I suspect it is too, but hopefully a factory reset will help.
I tried to follow these instructions at Hardreset .info - but rather than the recovery screen I just get a screen telling me to plug the USB in and to go to pcsuite.mi.com. Fine for backing up, but not resetting! Any suggestions?

Was wondering how you would do that with no touch screen. Tried mi flash tool? Or fastboot? Not sure how far I would go if having to return to vendor. Is it possible the cable wasn't connected properly from new and just totally came off. If you're brave could take battery cover off and take a peek. Don't know what the answer is unfortunately.

Hard Reset not working?

Today I got my Kaiser back from repairs. I got my mainboard replaced because of connection issues. It came back with it's original 'software'.
After installing Hard-Spl (white screen edit) I successfully flashed "Dutty's Official WM6.1 5.2.19209 Release" to my Kaiser.
I wanted to Hard Reset my device using the soft-buttons and soft-reset method, but it seems to be broken (?). I managed it in the past (before flashing and repairs) but for some reason it doesn't work anymore. Soft-resets and Bootloader mode still work.
Anyone got an idea?
Thanks in advance
P.S.: In the meantime I hard-resetted my device by going to Settings => System => Clear Storage

Few Tricks, Make sure you are not plugged in USB. Make sure you are not "fat fingering it." Some people use chopsticks to be sure. And Hold it for long after the Screen goes Black.
Believe me, I've already tried the things you said.
Although I successfully mananged in the past to hard reset my phone, I checked the threads and the following vid:
How To Hard Reset Kaiser:
http://www.youtube.com/watch?v=fZPzT_L2FZQ
Usually I am the problem, but this time I can't figure out what I'm doing wrong.
Just wondering:
Which part of the Phone (ROM) is in control of the Hard Reset part? (e.g.: Bootloader, Radio Rom, Regular Rom,...)
Use "Clear Storage". It does the same thing.
Also, JM is most likely correct. It is most likely an issue of how you are pushing the buttons. Make sure you hold only ythe soft keys first, using your fingernails, then push the reset tab on the bottom & hold it. Don't just push the reset & release, but keep it held down.
Based on your previous message about your phone being haunted - mine is too btw, I think it's because the soft buttons aren't being acknowledged by the OS - which implies some REAL big problems.
I took mine back to the T-Mobile store today where I got told that it needs to be sent back to their workshops to fix it... and then got told that "mostly they just send out a new phone".
My phone is exhibiting the following symptoms.
1) Green and Red phone buttons do not work.
2) Soft buttons do not work.
3) D-Pad and wheel work intermittently.
4) (and most strange) the back-space key on the slide out keyboard does nothing, and on the virtual keyboard it flashes (to suggest that the key is being pressed) but still does nothing.
I've tried to access the bootloader, and perform a hard reset. I'm now looking for the original T-Mobile ROM to install (which was why I went into the shop), as the issue around the backspace key implies to me that the issue is in the OS not in the hardware.

Thanks already for all the input.
I've been trying all weekend in every different possible way to perform a hard reset. Fat fingering is really no possibility anymore. I've used every possible tool I had (needle-nose pliers, chopsticks, pens,...) to eliminate fat fingering.
But nothing helped. Jon (a nice guy) might have given a possibly correct diagnosis for my problem. But it wouldn't explain why I still can get into the bootloader.
Problems since receiving my phone from repairs:
Backlight changed out of itself => performed Hard Reset
Phone pad pops up and seems to start dialing => flashed new ROM
Wakes up constantly after a few seconds from standby => performed Hard Throw against the wall
As you can see, my latest problem is that the phone automatically wakes up from standby after a few seconds. The weird thing: it only does this when I put it in standby, but it doesn't wake up if it enters standby by itself.
=> NOTE: This may support the 'fat finger'-theory: the Kaiser gets some sort of keyboard input due to faulty hardware. Therefore I cannot Hard Reset my device, because of the additional faulty input.
I've used the "Clear Storage" method to perform one of my hard resets, but this has to be solved. I will be sending the phone back for yet another repair.
Thanks again for your input everyone.
Problem found?
I think I found the problem:
I just noticed that the camera button is already pushed in halfway (like when you focus the camera before you take a picture). If I push the button gently, it immediately takes a picture without focussing (it does automatically focus before taking the shot, but not on my command).
Also, when I enter the camera app, it sometimes instantly focuses. Other times I cannot focus at all.
Hard reset is still no go.
Yet another thanks for your useful help.
Maybe found the solution?
Hi Guys...
I found that by tapping the base of the phone, it "unlocks" itself, thereby making it work. It's become *S*L*O*W* as hell, and I'm really tempted to ask them to take a look at it, but right now I need all the functions, so I'm holding off.
But, give that a try and see what happens!
Jon
Thanks for still answering my question. Go community!

Last week I finally received a fully functional and working Kaiser (have been waiting for that since december...). I couldn't accept a disfunctional Kaiser coming back from repairs.
The problem did indeed seem to be the camare button that was stuck. I tried really hard to get it to unblock, but I didn't work. I must say, I didn't try your method (didn't think of it).
Still thanks a lot.
I am experiencing exact same issues on my Kaiser (Tilt), it randomly starts to type stuff in the phone application on its own and I can't do anything to stop it, I have replaced ROMs, SPLs, Radios, now using a shipped rom with shipped radio but still that problem comes up after a few days of usage and doesn't go away until I hard reset, anyone knows what I can do to fix it? it's probably out of warranty. I checked the camera button and it seems fine.

Touchscreen not working??? HELP

All my hardbuttons work but nothing works on the screen no matter how long i press down or hard or soft. The touchscreen just isnt working. I just woke up this morning and it stoped working.
Does anyone have any thoughts?
Please help I dont understand why its doing this I cant turn my volume up or anything
Well,
You still have to provide a few more information if you really want someone finding out the cause of your problem!
What have you done last on your device before it happened? Are you still running on the factory installed ROM? Have you tried SOFT RESET and HARD RESET yet? And so on ...
Hmmm,
people always seem to forget that we have no clue about the actual condition of their devices! We further can't possible know what they have tried already to solve the problem. In addition, it is important to remember what had been done last on the device before the problem occured (such as installing / removing software, screwing with the device's registry, reflashing, giving it a bath and so on ...)
Well the last thing I installed on my phone was slide to unlock and that was like a month ago. I have soft and hard reset and I'm stuck in the set up after the Hard Reset were it has you touch to continue. I am on factory rom. The only software on it was TomTom 7, spb shell, slide to unlock. Everything worked fine on it and then I touched my screen one day and noticed it wasnt responding to my touch and it really just came out of the blue like I have not dropped it or got it wet or anything no problems until now.
Any other information you need let me know?
Thanks

Touchscreen broke, way to bypass welcome screen?

Hey all, I've been looking around the past few days and didn't see anything on this particular issue.
Basically, I washed my G1 and had to get a new one. The one that got washed has been starting up (slowly, and not always), but the touchscreen no longer works. I reflashed the software to hopefully alleviate any of the problems when it was starting up. My initial thought was to use fastboot to flash the backup I made on my new phone with nandroid, but the bootloader isn't working properly (I'll try a reflash of that too).
So, do any of you guys know of any other ways to bypass the startup welcome touchscreen?
Try placing your finger on the Android, press the trackball, then lift the finger and press the trackball again

Flash the ADP1 software.
Edit: You'd still need touch for that, sorry.
The driver was all wonky, uninstalled, reinstalled, fastboot works now Flashed over to my new G1's state, but forgot to take off the lock screen... Flashing yet again. Everything should be good from here.
Edit: Alright, washing the G1 makes it wacky. The touchscreen works now after restoring it to the new G1's state. Weeeirrrdd.
Edit 2: Anddd now the touchscreen doesn't work :S
well.. when my touchscreen broke i used remote control software to control my ppc from pc .. thats one way to bypass welcome screen, but won't get you much further. I used it for making a backup from my phone.
just leave it off for a while and keep it someplace dry and warm so it can dry out.
You may try to modify build.prop in the rom you flash
ro.setupwizard.mode=DISABLED
I think it will skip the setup
Sorry can't help myself. In the laundry?
I guess I'm wondering what exactly you did. I'm assuming it didn't make it into the dryer....
If you need the data off it, you might be able to ADB pull what you want to keep. If I'm not mistaken, ADB is as close as we have to remote controlling for Android at the moment.
There may be some places around, like PPC Techs, that can do hardware repair. I'm guessing what will happen is you'll occaisionally get it to work for brief stints after reflashing or whatever, but it'll keep conking out until the hardware issue goes away/gets fixed. Hardware issues do that, printers, routers, sometimes PCs.
Not to be a naysayer, but I don't think changing out the software is going to help.
I washed my G1 (was in pocket of jeans under the water for about 90 seconds), and after that I disassembled it to let it dry. It was running fine up to the day I SPL bricked it.
Hey.. i split water on my phone.. it couldnt have been that much but the touch screen wasnt working.. thought if i factory reset it, it may started working..
I dont actually understand all the lingo you guys use.. but any ideas on how i can fix it?
J x
oh the main issue is i cant get past the touch android to continue set up... please i just want my android to work!!! J x
I'm having a similar issue... My phone randomly stopped loading android.process.acore and it's messing with my heart. The touch screen doesn't respond but I can use the trackball to navigate, and every acore process force closes instantly upon activation, such as dialer, contacts, music, etc. The wonderfully helpful people at T-Mobile instructed me to do a factory reset on my G1, and it should fix the problem.
New problem: I can't get past the "Touch me, I'm an Android logo" screen. When I click Emergency Dial, it force closes because the acore processes are still messing up. The intention today was to reload the Cupcake SPL and Radios onto the phone. The issue there is that I can't touch the screen to start the USB connection with my computer.
Anyone have any suggestions aside from paying another $130 bucks??
This will do the trick
google androidscreencast it will allow you to contol your G1 via your PC
...let me know if you have resolved android.process.acore im on the same boat and a wipe and flash has yet to solve it...
same boat for me too! wow, this is three, maybe 4 of us currently experiencing same problem!
I love screen cast. Droid explorer is great too, basically a GUI for adb, and has a plugin for screen cast. Too bad you have to be online though, I'd love to use screencast offline!
I'll update if I figure out the error problem!
Well it looks like a complete wipe and a flash back to non root status is whats gonna take to fix the android.process.acore issue. BUT now w/o root, I cant access the G1 via android screen cast...so im totally stuck on the "Touch Android to begin" screen... sucks to be me lol
I think I'm in the same boat. I didn't know about the screencast application before I did a complete wipe to stock. So I'm stuck at the "touch android" as well. This phones pretty much junk to me right now.
I wonder if any of you have tried restoring your latest back up?
Yes, no help, either on the touchscreen, or the incessant errors. I think there must be some code that checks whether the touchscreen works, and sends back an error if it doesn't. I've tried almost every combination of radios and spls mixed with several different cyanogen roms going back to 4.1, both fresh installs and nand restores.
Currently I'm running the latest cyanogen, radio and hard spl. I get errors often, and can't use the phone / dialer at all without force closing. For now texts and google voice work so I have at least some communication. Ironically, I can't even unroot because none of the spls will flash dreaimg.nbh, but that probelm is in my unresponsive bootloader thread.
Sorry to hear about your predicaments allthrottle and r1ch. Strangely you are right where I'm trying to get, I have warranty coverage to fall back on.

phone stuck on white HTC screen, cannot load to OS

Hi all,
I was wondering if anyone is able to help me out with my HTC one M7. My phone has been out of commission since Monday night and I'm all out of options on what to do, I've even tried doing a factory reset as a last resort but that didn't seem to work as it looked like the process just stalled.
Here's a bit of background of what happened: Monday night I charged my phone through the wall outlet and went to have dinner, I came back to check on the phone and it was off. I thought that was odd so when I tried turning it back on I would only ever be able to get to the white HTC logo screen. I'm able to get into fastboot and recovery but after googling solutions and trying the options people have mentioned, it still isn't working. I'm not very tech oriented so I wouldn't know how to flash ROMs or anything like that...soooo, I'm hoping someone is able to explain steps in I'm able to understandr. I don't even know flashing ROMs is possible at this point since whenever I plug it into my PC, the drivers aren't recognized by Windows and says 'failed to install drivers'.
Any help is very much appreciated!! (I signed up to the forum in order to write this and seek help lol)
I haven't done ANY customization to the phone everything is all stock from my service provider so I'm really baffled at how this sudden fail could have happened. There was no OTA update either.

Unfortunately it's not, I've had the phone for a little over 2 years now. Seriously contemplating just using a loaner phone in the meantime while I wait for the new Nexus ...

Did you try factory reset from bootloader?

Yes, I did. It flashed to the screen with 2 green arrows in a circle and 1 downward green arrow with a progress bar at the bottom but nothing happens during this period. I left the phone like that for about 30 mins just to see if anything would happen and nothing did.

Trying to save files while stuck in soft brick

First, I will say that i'm not a developer. I am familiar with backups, rooting and custom roms. I'm just at a total loss with a total loss phone :/
So here's the rundown of my issue/s with my Moto Turbo (XT1254)
The phone is completely "unmolested." My phone is stuck in boot loop, currently. I did bust my screen a few weeks back but it had been working just fine. I picked up my phone to check texts, and I saw the "updating 24 of .... apps." Once finished, it's been stuck in a boot loop since. (Odd thing, my screen now shows split Moto image when trying to boot. Ex: a slot machine with only 2 roller wheels that wont match up)
I have tried to clear the cache several times with no luck of it booting up correctly. I do have files that I was trying to recover since they are not linked to a cloud account, and was trying to avoid a full on reset. I did, however, get frustrated and even tried to reset it back to full factory settings. That did not work either. So, all this being said, I'm back to trying to recover my files (my daughter's first year of life, family stuff, etc), since I cannot get it to even preform a factory reset. Does anyone have some guidance or same issue on this matter? Again, I am trying to salvage my files now while stuck in soft brick / boot loop status.
Thanks any and all who can help me with this!
******* Solved********
I have better diagnosed and fixed my own issue. I'm sorry I don't have pictures or video to better document what I did, but in short, it was as simple as replacing my damaged screen/digitizer, with a new one.
My theory was that during the update, the phone checked over it's systems and found that the digitizer was non-responsive in a few very small areas (this I already knew from using it a couple weeks with the screen damaged) and it somehow caused it to go into a boot-loop. My experience with fixing Playstations 3's, helped shed some light on this for me. I had a PS3 i thought was in good working order, updated firmware to it, and it bricked the system. Come to find out, the blu-ray laser head was no good. Upon the firmware doing system checks, it found that was bad and ended up bricked.
I did replicate the problem by switching the broken screen and new screen back and forth 2 more times after the initial fix. Upon disassembly, (youtube for teardown vidoes) you disconnect the battery from the logic board anyways, so when you boot the phone up, it does a app check and system check again. Every time the damaged screen was connected to the logic board and then powered on, it would end up in boot loop. The new, undamaged screen, would do the required checks, then boot up like normal.
I will do my best to borrow/rent a camera soon, so I can make a short video to show this works.
I'm not going to promise this will work for everyone but with replicated results, hopefully it's a fix for someone!
I hope
