Screen died - phone still works - is there a way to fix? - Xiaomi Mi Mix 3 Questions & Answers

Hey guys.
So today my screen just randomly died. Didn't drop the thing. Used it the one second, the other second it was just dead. Phone still works. vibration, touch, sound etc still works, but the screen will not display anything, not even booting to recovery or fastboot.
Recently installed the global ROM. I got the phone in the original Chinese ROM. This poses a problem. Ordinarily, I would have sent this thing off to Xiaomi, but I am fearing that I may have voided my warranty by unlocking the phone and also installing the global ROM. So, I would greatly appreciate input on the following 3 points
1) What troubleshooting measures can I take to try and get the screen live again?
2) I have heard that I can flash the original ROM and this might help my case for a warranty claim. Problem is - 1) I cannot use the phone's interface, this might make it difficult to navigate TWRP. Unless I can control TWRP through the PC command line? 2) I never enabled USB debugging on the flashed ROM. However, i flashed something recently through TRWP (the Global ROM region fix), so I am hoping I can still flash things through TWRP.
3) If I cannot achieve the previous two points, is it worth sending this phone back to Xiaomi. I bought the phone through Gearbest and I live in South Africa, so I imagine safe shipping will set me back anything from 50USD to 150USD.

UPDATE: I managed to boot to TWRP - using the "adb devices" command brings up my device ID. Maybe there is hope for flashing the chinese ROM if I can simply navigate TWRP through the command line.

Is there not a fastboot image of the ROM you can flash? I'd send it back in anyway, chances are they'll just replace the screen and flash it back to stick.

Yes I believe there is. But I hope I can flash the original via MiFlash.
On another note - ive been doing some reading and apparently black screening on Xiaomi phones is actually quite common. I am beggining to think my black screen might be a software problem with having moved over to the global.
If anyone has some spare time - I would appreciate a step by step guide on how to revert to the chinese ROM (i am busy downloading it). I am hoping this might fix my black screen, and if not, then atleast I can send the phone back to xiaomi with stock ROM and make a warranty repair/refund
Thanks.

mi mix 3 very fragile
black screen, same happened to me, new phone, fell down and black screen. not broken , phone still vibrate, and ringing at a call . nothing shows up, useless . I had 3 xiaomi phones before, I broke the screen but they still work.
I destroyed a note4 screen after a car pass over it ( feel from my pocket driving my motorcycle,).and still work. I Have also a note5a prime with broken screen totaly working. Then I loved MI phones.
this mix3 is a ****, a little fall down,(whit gorilla protection in the screen and with
it the cover on it , and become garbage). I will not reapair it , will repair my note5a prime.
Lisent this : if you go fishing and your are not taking well care of your phone do not buy xiaomi mi mix3
it is slippery .
If you know any solution whitout replacing the display module, will appreciate. Regards. Martin

I had the same problem, do you have any solution without replacing the display?
Regards Andreas

my screen was replaced.. had same problems.

I broke my screen. Went to xiaomi hk and they fixed it. 860 hkd which I thought was fair.

i9023 - Replacement screen touch input not working

Hi,
I recently dropped my i9023 and smashed the glass.
Bought a new screen with digitizer from global direct parts (www globaldirectparts com/Samsung-GT-I9023-LCD-and-Digitizer-Assembly-p/smsng6102150.htm)
Having put the new screen in it boots up fine and displays perfectly but the touch screen is not working at all and I can't do anything. If I put my smashed screen back in touch input works fine.
I've flashed back to stock I9023XXKB3 and I9023XXKB1 firmware, but nothing seems to help.
The ribbon to the screen doesn't appear to be damaged and because global direct parts had a minimum purchase of 2 I have 2 new ones and they are both unresponsive.
Anyone have any ideas?
My first idea would be to have the manufacturer fix it.
Sorry you are having trouble getting the touch screen to respond. I too have cracked my screen and would be very interested in your strip down and replacement steps as I am going to be doing the same. If you get time, could you write down your steps. There is a pretty good teardown at
http://www.ifixit.com/Teardown/Nexus-S-Teardown/4365/1
but I am not confident of the last bit of using a heat gun to separate the screen from the frame. Did yours come off easy ?
Yes I could have sent it to an authorized repairer but I would of been without the phone for a a while and it would cost twice as much. Plus I like pulling things apart.
markread544 - I pretty much followed the ifixit guide. however when pulling out the motherboard make sure the front and rear cameras and speaker are loose as well otherwise it wont come out.
I didn't use a heat gun, I just applied pressure until it started to lift, it would of definitely been easier if it had been warmed up but I didn't want to use a heat gun either. You would want to use an adjustable heat one on low if you did, I think a hair dryer would work as well.
I pulled mine a bit further apart then they did, the grey part in the attached pic comes off as well which makes it easier to get the screen out of the front bezel which it is also glued to.
Phone is back together at the moment with the cracked screen but I'll take some photos if I pull it apart again.
same problem here.
i bought an lcd on ebay for i9023 (slcd)
display OK , but no tactil response.
i had MP the OP but still no answer.
if you have any suggestion
thanks
how much for the screen? seems that 9023 is cheaper than 9020
80 euros for the less expensive , about 120-150 for the others
I ended up returning the screens from global direct parts and after about a month they gave me a refund.
After being quoted AU $250to get the screen replaced by an authorized repairer I decided to try again and bought a replacement screen on eBay from a seller called stream_beautiful for $86.
Got it today, installed and it works perfectly. No idea why the original screens from global direct didn't work.
I'm sorry to bump such an old thread, but I was wondering if there was any more information on this issue... I ordered an i9023 screen to repair a friend's phone about 2 months ago and had the same issue as the OP with it; touch input didn't work. I then contacted the seller (forceviewer on aliexpress) and he told me he'd replace it. After sending it back I then had to contact him again and send him pictures of the back of the old screen (with which touch input still works) because according to him there are 2 versions. Now I received the second screen a week ago and lo and behold, it exhibited the same problems. I noticed a number on the back of the screen is different, and the atmel IC (which I assume handles the digitizer input) has a different number on it too, however the seller has now adopted the position that it is definitely the correct display (quote: "If the pictures is right
The item will be right
I just send you the one same with your picturs
There are only two version.
Thanks")
Can anyone shed some light on what causes this? I know the guy's company tests their displays before sending them out, so that's probably not the problem, and receiving 2 faulty units in a row would be a bit weird, so I guess there's actually multiple versions (with a different digitizer controller IC?) which aren't compatible with each other... How do I make sure I'm getting the right one for my friend's phone? And, optionally, how would I go about convincing the seller to take this one back too and send me one that really works?
I'm having exactly the same issue...two replacement screens and touch input non responsive, re-install original and hey presto no problem...what I have noticed is that the part number on what I assume is the digitizer is different...
original -> KJ00423-101228-P00-7F-1
replacement -> KJ00423-101228-P00-5F-1
Yeah, my replacement says 6F-1 at the end, I can't check the original right now because my friend has his phone, but I'm willing to bet it doesn't say the same. Maybe I can make my case with this with the vendor, I'd really hate to have to buy another one of these displays for nothing
Guys,
It's the third SLCD screen that one of my fried is replacing to my I9023 Nexus S, and none of them is working. Yesterday he told me that when he bough the third one, the seller told him to "reprogram" the phone, because the drivers for new SLCD will be installed only then.
To be honest I didn't quite understood him, so, I though that the seller means to flash with a ROM. I did that, I installed CyanogenMod 9, everything went fine, but the touch still not working .
Does anyone knows how the phone could be completely wiped. Meaning everything what is in it to be reinstalled from the beginning....
I don't know what else to do, besides to buy a new phone
Hi All,
Just want to ask if anyone came to the solution yet ...?
Cheers,
no touch
Hello
i have the same problem:
1. The display works
2. But no touch reaction
i had bought a new screen for my I 9023 .
thanks for solutions
Yep, I have the same problem.
Original: KJ00423-101216-P00-1F-1
Replacement: (Not responding to touch): KJ00423-110207-P00-1F1
eBay Seller: mike410512
Bump - anyone sort this issue out?
I know this is an old thread, but since I have a shattered SLCD screen and i'm willing to replace it, i'd like to know what to do in case there's no touch response...
To get touch input again
Hi all,
I have smashed my phone screen twice on my S3 i9300. The first time I had the issue with the touch screen not detecting input but displaying correctly, I had taken it to an authorised repair centre and initially they did not know what was wrong.
There is only one way to "fix" this situation. You must remove the custom recovery and then reflash your phone with the stock samsung rom. Flashing the stock rom with stock recovery should pose no problem as it will be "official" and thus not blocked by stock recovery.
After reflashing, you must do a factory wipe + data reset. This is where you change your screen, making sure not to boot the phone for "the first time". If it does not work, repeat the reflash + factory wipe and try again.
The samsung rom will register the new hardware profile, and touch input will work. Why it works this way is beyond me, but taking these steps when changing the screen on a custom rom will ensure that the touch input works. Perhaps custom roms "borrow" drivers left over from stock rom? I don't know.
You can back up your current rom and restore after messing around with the samsung stock rom and you have gotten your touch screen working properly.
I have tried a whole heap of different "solutions" with this problem and this is the only one that works, and if you are taking it to a repair centre, make them aware that you have a custom rom installed.

Phone reboots constantly with blank screen and No touch capability

I recently bought an MTK6573 S820 (T9199+) Android phone.
I was following instructions to update ROM in order to improve 3G service. However after ROM applied and phone rebooted the screen was blank. only back light comes on.
The phone constantly reboots and I cannot get to so anything on it.
Is there anyway I can flash the phone with the original ROM or something? I am desperate as the phone was pretty nice and I really liked it.
Please Help.
Can you get into the bootloader menu? I have never heard about your phone, but should be holding the volume button while turning on the phone.
I don't remember the version of the bootloader version of the few times that I went into recovery mode before I am seeing nothing on the screen.
It loads up as if everything were ok then it restarts after a few seconds. That process loops.
I am able to use adb tools and confirm that the phone comes up in recovery mode.
If I were able to remotely run the update.zip remotely I may be able to restore the phone. I am also unable to flash the various ROMS using SP Flash Tool. I am hoping you guys can help me.
I have the same phone and also noticed that the 3G is not 100% where did you get the new ROM from as I have been in contact with supplier an none available?
I have been having a problem with a noise coming from my phone to the other party but not on every call it also fades in and out, they can hear a buzzing sound or like a helicopter noise but i can hear the other party ok , so just stripped the phone down and cleaned all contacts also moved a piece of mesh tape covering part of the Mic and so far no problem , but being at work will test that out tomorrow
it would be nice to be able to turn the Mic Volume up a bit (any help ??)
I rooted this phone about a month ago with super one click and put link2sd and freed up internal storage this extra partition on sdcard which works just fine

Apparently that was my problem. There seems to be a number of phones that have the same model number. I pulled a ROM from the site that I got from a document that came on the mini-disc that came in the package. Apparently it was the wrong ROM which threw my phone off. Even though the model number and specifications were the same.
I have sent my phone back to my re-seller for repairs in China. I await feedback from them soon.
I recommend not installing any update for the phone as I am not sure. There is a guy Bruno that does custom ROMs for android phones and he had done a ROM for the phone I imagine but stopped development due to no funding. I am not sure if the ROM he had was for the same phone.
I wanted the update to assist with the 3G service as the guys were promoting that that was a part of their upgrade.

How about your s820? Did you get it back?

Kudos To OnePlus Support

I had an issue with my phone last week that required an RMA. After Tier 2 did there thing, It was still unable to boot. I could get to Fastboot but without the phone booting, no way to set the options for OEM unlock or to boot to TWRP. There is a special tool that is only meant to be used by OnePlus techs but it does a low level reinstall. I used it and my bootloader locked again but still would not complete it's boot. After OnePlus tech had their crack it at I was given an RMA. I thought it was pretty crappy that I had to send my brand phone to Texas. Since the phone was a paperweight, and there were no other options, I shipped it back on Monday. To my surprise, my phone was returned today and fully functional again. It needed a new mainboard. Believe it or not, that phone was waiting on my porch when I got home. They replaced the main board but I can see no probelm with the phone fit an finish. I know it's my phone as the IMEI's are the same and it came back with my screen saver on.
They told me 7-10 days,. I sent on Monday and received back today,
Everyone with a OnePlus 6 should find the MSM tool that Oneplus uses. There is a site with the version that does not require OnePlus to log in. Most hard/soft bricks can be reset back to new. Even if the screen is dead. The only qualification is you must be able to turn your phone off. If the phone will not turn off, this tool will not work.
My issue was hardware so no tool was going to fix it. The above will work for anyone who can turn their phones off and are having OS issues. I don't want to post the link but just search for "Free Oneplus recovery tool"
I was VERY impressed with the service center (ACER, in Texas) for quick turnaround,. Think I'll by a Square Deal warranty now.
I think you got a new phone and they just transfered everything to the new emmc card includeing efs partition. I am guessing OP6 is soc (system on a chip) and would require extensive machines to desolder and solder chips to new board. I think I really like this OnePlus though. It was so easy to unlock my bootloader.

White vertical lines showing up when i start my oppo a39.

My phone's screen was broken. So, i went to a shop and the repairer installed a new one. The phone was working fine. I updated it to Marshmallow but it has some brightness issues. So, i decided to downgrade it. I flashed my phone and after flashing, when i restarted it, my device is showing white thick vertical lines and then my device turns off. I tried re-flashing but still i have same issue. I cannot buy a new one as i am a uni student. I need help. it has almost been more than a week and i am without any smartphone lol. Kindly help me. Thanks! I have OPPO A39.

Probably because the replacement screen wasn't the exact same model as your original screen, meaning that the repair shop probably had to flash a different kernel or a modified kernel to make the different screen work with your stock software and when you updated to Marshmallow it probably flashed your stock kernel(the kernel that would have worked with the original screen but not exactly right for the new screen). If that is what they did, you might need to flash a different or modified kernel to fix this.

Mi Mix 3 Bootloop after screen replacement

Hi, I'm new to the forum and to mobile operating system troubleshooting in general. I'm hoping to gain some insight into an issue I'm having.
I broke the screen on my mi mix 3 and after waiting for 2 months it finally arrived from Shenzhen. Yesterday I disassembled the phone, connected the new screen, turned it on, and it just went into a bootloop. I've never changed any part of the operating system on the phone before so I just assumed something was making a poor connection. I unplugged all the leads and plugged them back in again, checked that everything was firmly in place, and ended with the same result.
Fastboot will run sometimes for 10+ minutes and then the phone will just shut off, normal booting it will switch from "Mi" to "MIX" and the animation at the bottom of the screen will freeze after a couple clicks and it will loop back to restarting (but twice it has just ended with an all white screen). Rebooting from Mi Recovery mode results in the same.
From what I've seen I'll just need to follow this and flash the phone : https ://c.mi .com/thread-2504118-1-1.html?t=1590725045909
But my question, is there any possible way to try to fix this issue without loosing all my data and without using a back door method that may just brick the phone?
Thanks for any help, btw I still have the back glass off (I've tried with the fingerprint scanner plugged in, nothing) just in case it could somehow be a hardware issue.
So I've given up on trying to save my data, I don't really care much about that to be honest. I just really like this phone and would like to use it. I tried to flash the phone using Miui's official instructions but I can't unlock the bootloader because I can't download the app Miui's flash tool is requiring me to download on the phone to authorize it.
I guess I'll keep looking for a work around.

I changed my display too and it's bootlooping. Did you solve this problem?
I changed my Display too...everything worked fine when I tested it. I unplugged it again to clean the phone and to bring on the glue..when I had the Screen on I restarted and had a black screen...so tried to remove the screen which then just broke...so I ordered a new one and a new display flex cable - I didn't glue the screen yet because I either experience black screens when the screen gets pushed against the backplate or the phone ends in a bootloop -> for the bootloop thingy I just waited for about 10 minutes and then it started normally so there must be something with replacement screens...I don't know whats going on -.-
Hi
Has anyone managed to get this fixed?
The screen works initially but after a while it goes blank, reboot I get the Mix logo not mix 5G. The replacement is a LCD.
Looks like it is stuck in bootloop as inserting sim does phone does not ring when I call it nor front face camera clunk when I slide it
