Black screen: blind OTG keyboard guide? - Xiaomi Mi Mix 3 Questions & Answers

My Mix 3 has a completely black screen after I dropped it... . I'd like to recover some data from it. If someone has some time to write a "blind" guide for an OTG keyboard to enable debug usb it would be nice. I lost a lot of whatsapp messages and stupid me I was so sure to have the backup enabled.... :crying:
Hope someone will help me. Thanks.
Or can someone tell me how to unlock it with a keyboard if I'm using the pattern lock? Never noticed what you can do if you cannot use the pattern method.

Nope. Only solution was to repair the screen. Likely I paid about 130€ directly from Xiaomi official repair service.

Get the program 'scrcpy' off its GitHub, connect your phone to your PC with a USB cable, open a console in the scrcpy directory and connect to the phone with adb, then run scrcpy (from the console too). scrcpy will mirror the framebuffer to your PC and let you send inputs.
Of course, this only works if USB debugging is already turned on on the device.

The other option would be to boot into recovery and use ADB from there, this is fairly easy if you already have twrp installed. If your bootloader is unlocked, you can flash twrp and go from there.
By default iirc twrp won't mount the data partitions, so you will need to do that by issuing ADB shell commands, once done you can pull data out of whatever partition you want.

Edit:
oh sorry I didnt realize it was locked nvm

Try qtadb to extract files. You need to setup adb on PC to make it work (of course if debugging is on).

Sorry for late response..ive been having difficulties with my pc xd
It didnt work for me..I gues debugging is off
Is there anything else I can try? Im trying to find usb host adapter or female to female cable, but they are not selling it in my country xd
I think there is no way left for You. Only usb-otg or touch screen replacement may help.
Are you able to see your pad's screen when you plug it into HDMI of your tv/monitor?
Edit: sorry, nvm, didn't see that u can't input at all

I'm just trying to help by throwing around some ideas. If you have a keyboard dock (or know someone who would lend you theirs), you could use the touch pad or plug in a USB mouse and unlock it that way. The mouse pointer registers on the device, and you can use it like your finger to unlock it. I've used this method to unlock my tablet when the sometime the touch screen did not respond well.
Hope I helped!

[Q] Need Debug on, but screen and power button broken, device still on and working

Hi guys!
I brooke the screen and touch of my razr hd, as well its power button.
I'm trying to acess its screen trough the pc using a tool from the forum. BUT I need to have the usb debbuging enabled, wich I don't have.
So, I need to enable it from de pc somehow.
The device is working properly, the pc recognizes it and allows me to deal with its files, the device is turned on and is rooted already.
Someone have any idea of how to enable the usb debugging with the touch and without entering in recovery or fastbootmode?
The only two things I know I can do with it for now is to reset or turn it off trough a command in cerberus.

There's a lot of info out there on this. Various way to recover. Maybe try this:

All the info in this 2 tutorials and in other I've found, in some how, ask me to use the buttons to acess fastboot mode or recovery mode, but as I said, they are broken.
I was hoping to find some comand lines via pc and with the device still on to put it to recovery or fastboot mode, cause then I can use adb or fastboot to enable usb debugging.... But, I still don't know how...

Broken Screen, how to get to my files? Need an android expert!

Hello everybody,
I know there are many threads with broken screens and so on, but I've been searching the internet the whole day & night and tried nearly every solution.
My Smartphone fell on the ground two days ago, I can see everything, but touch isn't working anymore.
Usually I'm rooting my phones but i didn't root my XZ5 so far (big mistake!), so I don't have a custom recovery.
I have USB Debugging activated, but I haven't connected my phone since it updated to the new firmware, so I'm getting RSA Fingerprint Message which I can't allow.
After my Z5 fell on the ground, the fingerprint didn't work so I had to restart my phone - now I'm forced to enter the key to unlock the system.
At first, I tried "Android Control" with adb, but when I connect my phone, adb says "unauthorized" - no remote control possible.
After that, I bought a OTG Cable and plugged in a mouse. This isn't working, because I have to search for a plugged-in USB device first in the settings (the phone doesn't recognize the USB device itself).
Fastboot & Flash Mode are still working.
Is there a possibility to skip RSA Fingerprint with USB debugging or deleting my lock screen? I thought of unlocking my bl and installing TWRP, but then the mobilephone would be wiped as far as I know.
Maybe someone of you knows a "temporary recovery" which can be booted from SD-Card or another way to get to my internal data..
It would be awesome, if someone could help me with this!
Many thanks in advance!
Only way i can think of are to downgrade to lollipop with flashtool without wipe.
Then the usb mouse should start to work directly if im not mistaken.
Atleast i think it was this they before mm upgrade.
Did you try to boot the phone with the mouse connected?

yes, unlocking would completely wipe your phone, including internal memory so it's not a solution.
Rsa key request means you cannot run any adb command right, included adb shell right?
Did you try to do an extensive google search with "broken screen rsa"?
Particularly, http://stackoverflow.com/questions/...b-rsa-key-with-broken-touch-screen-on-android
talks about rebooting in "recovery mode", so you could try to use adb commands in fastboot mode (or download mode)

So I recovered my password from the dust and figured this is my chance to help..
Better be working..
I dropped my z3c while I was holding my newborn baby, it contained all the pictures from birth, ****ing fool I am for not backing up..
Get that short '.. to usb' - thing from the box. Use that to connect your Bluetooth mouse and tada that should work. Use it to unlock your phone and do you what you want to do.
It worked for me, hope I can help you.

Broken Screen

Hello guys, my phone dropped today and half of the screen is not working anymore. Also the touch does not seem to work. The problem is I just want to copy my photos to my computer but i cant because of the phone is locked and it needs a pattern password to unlock. Is there anyway without replacing the screen to copy my photos or unlock the phone. Thank you.
Hi,
You can plug an OTG cable and plug in a mouse to work around the touch screen issue. Other possibility is trying to boot in recovery mode to manage the files via USB, though I'm not sure if it would allow you to access internal data using adb or not.

Hey i do have the USB OTG and i plugged in a mouse to try to enable the adb debugging but the problem is that i can't see the screen so i am working blindly and trying to 'guess' where i should click.
The thing is i can unlock my phone with the fingerprint, but when i connect it to the computer the files do not show, i believe there is a button i have to click to enable MTP ?
I really can't believe its that hard to copy some files from my phone just because the screen is black
Hi,
Yes there is a button to enable MTP and it is in fact hard to enable it without looking at the screen. Have you tried booting in Recovery to access your files?
All the best,

LEO-BX9 No USB Debug option ... Help?

#1- I have the LEO-BX9 and can not get it to connect to a computer via USB regardless what I try. The computer does not even acknowledge anything is connected when I plug in the charger with the watch. I have tested the charging cable and every connection is working fine (no broken wire or issues detected). I've tried on multiple computers with multiple OS and nothing.
#2- There is no option in Developer Options for "Debug by usb" it only has Debug by wifi or bluetooth.
I have been able to connect adb via wifi, and can send commands, but when i reboot into bootloader, it obviously loses wifi connectivity and I cant send any fastboot commands, and can not communicate at all with the watch. As such, I can not unlock or do anything.
I appreciate any help you can offer and thank you in advance for your awesomenes!
I guess my ultimate question is, How do I get a custom ROM on this watch without being able to connect while in stock bootload? Can I push a file over with ADB and use it somehow to install the custom ROM as a fake update or recovery. Can i unlock somehow. Anything? I beg help from you oh wise and kind xda'ers
