Question Save data with broken display (black screen) - Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40

Hallo,
the display of my POCO F3 is broken, meaning black screen. The device itself starts normally. How can I save my data? USB debugging is disabled and I can't activate it because the broken display of course.
Could anyone help me to save my data?
Thanks in advance!

Your data is safe. However you may need to wait awhile to access it.
Your best bet is to get your screen replaced.
Call around to local cell phone repair buisnesses and see if they any replacement screens in stock for the poco f3. If you have a xiaomi repair center near, even better. If no one had one in stock, your best to order one yourself. (this is where you may have to wait a bit as it may have to be shipped from china) if you're comfortable replacing your screen yourself, do that. But having the broken device in hand, with its replacement screen, and taking those into any cell phone repair store, they should be able to fix you up pretty quickly and shouldnt be too much money since you did the leg work of retrieving the screen.
That's the route I would go, or at least get the ball rolling in a new display coming in the mail. Because trying to retrieve that data without usb debugging on, may be a bit of a rabit hole.

Hi,
To save your data, did you try this (with a PC of course)
https://github.com/Genymobile/scrcpy
Maybe you still have access to the phone despite the broken screen.
Let me know if it worked.

Not well read, "USB debugging is disabled", so it will not work....Sorry

Thanks for the suggestion, but honestly I don't think it's worth it. I have already received offers and they are from 190 € upwards. And I do not trust myself to exchange the display. In this case, wouldn't it make more sense to request a data backup from a company? I don't know how expensive that is though.
Isn't there any way to backup the date in recovery mode? I know that pressing the start and volume up button will get me into recovery mode. I've read somewhere that from there I can back up my data via the MI PC Suite, by pressing the down button twice. Is that correct? Regardless of that, I haven't yet managed to get into recovery mode with the broken display.

You can get a display and just connect it (don't remove the old display, just connect the new one).
It's silly that "ro.adb.secure" only means that it has to handshake and popup to allow ADB.
There really should be a mode where you say, "Only the 3 computers that I've already connected are acceptable and allow no further new ADB clients".
Then *everybody* could leave ADB on all the time.

Could you explain to me, how to do this or provide a link to a tutorial for example?

You'd just open the back of your device. The screen hooks in with an orange flex cable. You just disconnect the old one and plug in the new one out the back, just flopping around. You won't have touch, but you can hook up a USB mouse.
I don't know your model. I can't get more specific.
It's just that a new screen by itself out of China can't be too expensive?
And if you like, after you get your data you can try to actually replace the screen yourself.

I have got access to my daughters P30, with broken display, over MHL display. The difficulty is just to find the right place on the display to allow MHL display.

Thanks, perhaps I will try this!
By the way, it's a POCO F3 as mentioned above

But won't I need to enter my pin first to allow the MHL display?

If the touch is still working you may be able to enter your PIN.
Get a similar size device, go to the PIN screen, mark the position using clear wrap and a marker. Transfer the positions onto your screen.
Or use a scrap of plexiglas, mark it, then drill small holes and use that to mark your phone.

Or use an usb-keyboard.

[Q] Conundrum, take phone apart or is there another method?

My brother recently broke his GS3 (dropped it and cracked the screen and digitizer). I have been looking for a project phone to turn into a remote cell switch to turn on a heater and some other electronics at a storage place not near my house (hence it will be warm when I get there).
The problem is that he didn't have the debugging turned on. After some searching on the forum, I don't think I will be able to root it and restore it since the screen is completely blank. I also own a GS3 that works. I tried connecting the HDMI connector to the broken phone to see if I could get it to display on a television. This did not work.
My question is... is it possible to root his phone and get it going? I am not worried at all about preserving any data on the phone. Or is this impossible because the screen is cracked? Is it easy to disassemble the GS3 and use the working touch screen on my phone to boot his and start the rooting process? I would prefer not to do this since my phone functions properly, but would be willing to try. I watched a couple tear down videos and it doesn't seem overly complicated, I just hate to destroy a working phone.
Let me know your thoughts...

1) First, as it goes goes online.
2) What you propose (switching the boards and hooking up the screen and the other necessary parts is entirely doable.
If you were to do that, you'd need to find a way to eventually replace the phone's broken parts so you don't have to switch boards just to use it as this test device you propose.

Yeah, I have been doing research for awhile now to see if I could do it without taking my good phone apart. However, most of the guides that I found required using ADB and having a phone with debugging turned on. I was trying to find a last ditch effort before I decided to take the phone apart.
I should only have to swap the board once, right? Once the device is rooted, I should be able to connected it to a computer and control it that way?
For a better understanding of the project. I have built a test board with some transistors that accepts a standard headphone jack. Using my phone, I have been able to get a square wave to trip on a standard Christmas light timer that will run for 2/4/6/8 hours before automatically turning off. My plan was to set the phone to silent, and use the configurable ringtones to allow me to create a whitelist of friends that can remotely warm up the garage. I found a BYOD provider (ting) that is a pay as you go service that uses old sprint phones. Since the screen is cracked and cannot be answered, it is a perfect device to sit on a shelf. Thoughts?
Okay. So, I took the phone apart and managed to Frankenstein the two devices together so that I could get a working touchscreen.
I have rooted the phone into cyanogen mod 10.2. Using a tasker function, I am able to get it to activate the media player and trip the activation sound and turn on the pre heater.
I have two more current problems....
1.) I couldn't get the tasker (condi previously MiniTasker) to play the sound based on incoming calls. What is happening is a call from the "whitelist" will cause the phone to reboot. On the reboot, the tasker will cause the media player to open and play the file. Is there another way to do this? The current problem is anything the causes the device to "reboot" will turn the heater on. Again not a big deal since it is on a 2 hour timer.
2.) I couldn't get a screen share program to work. When I was on the stock samsung rom, I was able to get screen share but not screen control. I tried using several different applications (screencast / [email protected]) Does anyone know one that will work well with our phone? Changing the custom rom to a different one is fine (cant see it anyway because the screen is broken/blank). It would be great to see the screen every now and then as a diagnostic tool.
Thanks for the info!
Why not just buy a bad enough from eBay. Then you would have all the parts you need.

Do you mean buy a phone that has a working screen?
I don't want to spend a ton of money on this project and once it is complete it is going to spend most of its life plugged into a charger next to the wall.

[Q] Is there a way to test all of the device's hardware without the screen?

I broke the screen on my Note 3. I am considering replacing the screen/digitizer myself, however I am afraid there could be other hardware damage. I don't want to gamble on the screen being the only thing broken working, I'm thinking it might be better to take it into a shop and ask them to fix whatever is broken. Maybe I could replace the screen and then do that, I don't know... I'm sure there have been a million threads about poor saps breaking their phones and looking for solutions, sorry.
Anyway, is there any software available that would let me hook the phone up to my computer and run some general hardware diagnostics? I know the vibration, LEDs, and physical buttons work. I can't think of any way to test the other hardware though. The phone is rooted if it makes any difference.
I'm also just considering selling the thing on ebay and purchasing a new one, with insurance this time.
Give this a try... https://code.google.com/p/androidscreencast/
sent from my ??????? note 3?
Also you could mirror the screen, but in both cases the same problem comes up: how to install the program or change settings in menu without seeing the screen, assuming the touch pad works. Now, do you remember if there was a beep or some type of sound when opening programs before the damage? I think it's a factory setting, but I'm not sure. I would start the phone and see if there is any sound feedback when pressing screen, taking out the pen and walking away etc, anything to confirm the phone is actually booting up and responding. How about hooking up USB to computer and see if you can access it's internal storage?
I think T-mobile can run the sort of diagnostic you're looking for. My first Note 3 had a defective power button. When I brought it in for replacement, they took it into the back and hooked it up to some sort of diagnostic system to confirm the problem. Dunno if it will work without a screen, but when at another store, I watched them hook up and diag an iPhone with what I presume was the same system. They seemed to be working via the PC, not the phone, so it might work for you. Can't hurt to drop in and ask.

Thanks for the replies.
I think I'll use the screencast to test as much as possible. Not sure if T-mobile would do that for me, considering I don't have their insurance plan and they wouldn't be replacing it. Not a bad idea though.
Ended up purchasing a new screen/digitizer, so that'll be replaced. Just got to see if anything else needs fixing.

[Q] No Screen Image After Being Dropped

Hi all,
I just dropped my HTC One X (on the floor), and unfortunately there is now no image on screen.
I may have to take it to the service centre, but first, I would like to try (hoping) and see if its just some simple issue (cable connection came loose or something). I would want to open up the casing and see if I can do some quick fix.
Any advice?
Thanks!

well, i think it's quite difficult that a drop disconnected a cable, more likely the display got broken... anyway, you can always try to open it, but pay atterntion not to break anything, otherwise you will have to pay more to get it working again hope i'm wrong and that a cable connection is faulty and you can fix it by yourself :fingers-crossed: look for the battery replacement tutorials to learn how to open it, some are very good and exhaustive
Thanks, yup, I got the back casing open and at that point, can't see that any cable got dislodged, so you may be right that the screen got damaged. In any case, I'm not really willing to go any further than that.
Next question is, before I send in for repair, I hope to, firstly, retrieve my data on the phone, and secondly, wipe them.
The problem is that without a screen, I can't seem to be able to do that. Connecting to PC via USB doesn't give me access to the phone storage and I suspect that it is because it is in lockscreen (pattern lock), and, I suspect the input (touch) part of the screen is also not working (i.e. not just output / display, because my pattern lock normally would give me tactile feedback).
Hope to get some advice on how I can get some access to the phone storage via USB
FYI, I have
CM 10.1
CWM 5.8.4.0
Titanium Backup (just listing here for the heck of it - pretty sure it's useless in this case)
Anyone, please?

N7 screen went black

Yes, like it turned itself off but it did not go off as I was still getting audible email notifications. Tried everything speaking with Google support and then even Asus support who told me to go to their website and fill in an RMA form. This unit is 13 months old-out of warranty. There is nothing on the form relevant to the nexus to fill in so you cannot continue with it. So I am stuck right now and do not know what to do if anything. Any help would be appreciated.

Normally, 3 things can go wrong:
1. The cable is not connected properly. This could be caused by any impact. You take off the back cover and reseat it. It's the amber cable that runs the length of the battery. Be sure to check both ends. The one on the motherboard's end is in plain sight. The other end is hidden beneath the daughter board at the bottom of the tab, so you need to remove it to inspect the connection.
2. The backlight which illuminates the display went out. You can check this by turning the tab on and taking the tab to a dark room and shine a flashlight on the screen. If you can see the icons or the boot page, the back light is bad. The bad news is that you'd have to remove the lcd/touchscreen unit to replace the backlight. 10 times out of 10, when you do this on an original tab, you will break the touchscreen. Since it's glued to the lcd with LOCA (liquid optically clear adhesive), you will have to separate them, fix the backlight, buy a new touchscreen, then reassemble the whole thing. Most people would find it simpler to just buy a new lcd/touchscreen combo. If you're game though, I can give you an lcd back with a working backlight strip.
3. The video circuit on the motherboard went belly up. To test this, you need a micro usb to HDMI adapter like the one here , and a newer lcd TV. If nothing shows on your TV, the GPU is probably dead, in which case the only practical solution is to replace the motherboard since it's impossible to replace the GPU at home.
Good luck.

Did anyone else read this response and want to hit the edit button, and then type in huge letters "Time to buy a new Nexus!"
Thank you for your detailed reply. I checked the cable from the MB at both ends. Seems OK on the connections. I am unable to turn on the tab to check the backlight. That's about as far as I can go with it at this point. I am thinking that this tab is toast and to make matters worse, the abominably bad Asus customer service. I am considering replacing this with a Samsung and be done with it.

Hey, don't lose hope! Samsung is not any better specs or quality-wise (especially the display). If you're gonna butcher the thing anyway, might as well find out. I was gonna suggest to lend you a used lcd for you to test, but I realize people for some reason are extremely wary of gratuitous offers so I won't. But if you value it, try to get a screen with a good lcd but broken digitizer on Ebay. They wouldn't cost more than 15 bucks. Once you can determine it's not the motherboard, we can go from there. I can guide you on the replacement part if you want. I'm just a hobbyist, but I have messed around with this thing enough to tell.
Graph, you are kind to offer. I also have noticed that the glass has a few cracks in it as well. At this point, I can't turn it on. It seems like when I punch the on button in there is extremely little movement if at all. So I don't know if it is still on which I don't this it is or it shut itself off. When it was black screen and on, I was getting my email notifications audibly but since yesterday-none. I am not looking to spend big bucks on these things as essentially all I do mostly is use for reading. I do want to stick with android if I replace this. I know samsung does not have as good resolution but seems to get good reviews from users.

Recover data from a Oneplus 3 with broken screen

Yesterday my device fell and the touch screen broke. The touch commands only work in the upper part of the screen and the display is becoming darker as time passes. How can I recover my data from the device? I've usb debug activated. By connecting the device to a pc I cant transfer files since I cant switch to the right mode. Moreover the device rebooted so I'd need to enter the password but I cant right know becauseof the broken touchscreen.
Try connecting a mouse via bluetooth or usb to navigate your phone. I succeded a while back in the same situation .

Depending how badly you want to recover your data: https://www.ebay.com/itm/LCD-For-On...var=532360137925&_trksid=p2057872.m2749.l2649
My personal honest comment - OnePlus 3 is incredibly easy to repair yourself. I've disassembled many phones from different brands (Samsung, LG for example) and OnePlus 3 is literally the easiest phone I've ever dealt with. Go for it - buy that LCD with frame from ebay and swap components yourself (just make sure disassembly tools are included or buy separately). I've ordered this LCD with frame about a week ago since my GF's OP3 felt on concrete and got LCD damaged to the point that nothing is visible on the screen
Keep it in mind - always do backups of your important data. Automated synchronisation is what you should be looking for. For photos - Google photos. For contacts - Google account. etc.
