Data recovery on a phone without screen - Redmi K20 / Xiaomi Mi 9T Questions & Answers

Hello!
So, my Mi 9T suffered water damage recently and the screen completely stopped working. I took it to the repair shop but a new screen for it would be way too expensive to be worth repairing.
I have the device with me, and i really want to recover my data on it, it is rooted with magisk, bootloader is unlocked and TWRP recovery installed. Is there any way that i can access the data through USB debugging or something like that?
I tried intalling vysor through ADB install today but it gave the error "error: device unauthorized". It's probably asking me to allow USB debugging again but there is no way i can do that without a screen/touch working as far as i know.
I saw a youtube video telling me to use the shell command to try unlocking it and there was the error.
I also tried going to C:/User/.android and deleting adbkey and adbkey.pub, didn't solve the problem.

The only thing i want is to be able to use it through my computer so i can recover data and maybe use WhatsApp while my new phone is on the way.
Any help is deeply appreciated, thank you!

TWRP supports Media Transfer Protocol - access Imternal memory just like in Amdroid.
However, if you set a PIN/pass/pattern, TWRP would ask you to type in when booting to TWRP (but you can't if screen not working)

[Q] Webtop without dock

Hi I am new to this forum and I'm not an expert, I really would like to use the webtop without a dock,i tried following the instructions posted here but nothing happens, I don't know what am I missing. Am I supposed to run the install file on my computer or on my phone? When I run it on my computer a black screen appears and some command and then I says to press any key and that my phone will reboot, but nothing happens. Am I supposed to do something to my phone?
I'm on att gingerbread, not rooted, I enabled debugging mode.
Thank you
You need to root and probably deodex
sent from my Atrix via XDA premium
You are probably right, but why then on Fenny's post it says no root or deodex needed??

oh well look at that,
you run the script from your computer but your phone has to be connected and have all the right drivers on your computer

Can you please be a little more specific, I have the drivers for motorola media link and the phone portal, also for usb connection.
do you know what ADB is and how to use it?
No. I don't know... I just enabled the debugging mode on my phone

ok connect your phone to hyhour computer and make sure the computer knows it is connected
then run the script
good advice
If I were you I'd be VERY CAREFUL and investigate and learn all you can BEFORE doing any mods on your phone. Too many phones have been bricked (rendered useless) by running things you know little about.
I did that but the doesn't do anything, it doesn't reboot like it says on the script. I know it's connected because when I enable debugging I see the pop up screen for the internal memory and the sd card
Thanks for your concern I really appreciate it.what I like about this is that doesn't require root
Root
Hi
I also had exactly the same problem.
I wanted webtop, without really rooting my device.
It didnt work out. Also ran the script no reboot etc.
I then rooted my device, Fenny assisted me to create 2 files for the stock 2.2.2 atrix 4g (The older version of the os)
I copied them manually using root explorer, rebooted, and walla, i had the webtop working.
I still have those files.....
If you need them, PM me, its worth a try...

[Q] Help! Screen broke with PIN lock, need help mounting file system with CWM.

So I had the magical luck of having my S4 fall out of my pocket while closing my car door, shattered to pieces, no touch response from the glass.
The problem is, I had the device locked with a pattern & pin, so I can't just plug in and backup all my photos and stuff that were saved with local device storage. I also can't get adb to connect to the device (with developer options enabled), I always get a "device offline" error (I've updated ADB to the current 4.2.2 version, but I cant whitelist it because I can't allow it from the phone without touch)
Now, I still have root, and I was able to blindly install CWM (the OUDHS-Recovery-jfltespr-1.0.3.3.tar) version with Odin. I'm assuming it went well because I heard the sprint chime on restart.
WHAT I NEED: Is someone to either give me some screenshots (or number of button presses) to enable internal storage to be accessible by usb in cwm (also how to get into it too). I figure if I'm able to use volume presses and the home button I can get to my internal files. Other than this option I'm at a loss before I return it. If anyone can help I would be so damn grateful.
I'll draw you a picture too.
EDIT 1: I have a picture of the main CWM screen from a youtube video here:

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Now all i need is the mount and storage menu
So nobody can help? I didn't think a cwm menu was that hard to come by with an S4.

Were you able to connect with adb before? Was usb debugging checked in settings before the drop?
If you could get adb to connect, you could use a program like android screencast to view your phones screen on your computer.

That was my first move actually.
Problem is, even though debugging was enabled, I can't whitelist my PC from my phone. This is a new 4.2.2 feature to prevent data theft ironically.
All of these options will just return an "adb: device offline" error when it's connected. Trust me, I wish it was that easy.
You can't connect while in recovery either?
It would be kind of a pain, but you could pull multiple files that way.

Forgot pattern and cannot recover- nexus 4 with android 5+ lollipop

Hello.
I've repaired a nexus 4 screen and digitizer but I got it back because my friend can't recover access from a forgotten pattern lock.
He is running stock android 5 lollipop and he doesn't get the email recovery option when he inputs wrong pattern. I've searched even in google support but I didn't find a solution to recover his photos.
My main concern is to recover files and photos!!! There isn't a reason to suggest a factory reset....
--Phone Status---
Boot loader seems unlocked "Locked state is marked as unlocked in bootloder in red letters" while secure boot is enabled in green letters
USB debugging seems OFF: There is no android device listed in device manager. I only get a music player in disk drives which is empty.
adb devices command in bootloader recognises it
When entering to recovery I get the message "no command" along with the icon of an android under repair.
No dropbox no google+ photos backup
---What I've tried---
UPDATE: Managed to flash TWRP 2.7.1.0 I can see the files but since usb flash drive doesn't work I can't copy the files...
Android Device manager: Returns error that the phone is already locked and there is no need to apply new password.
Tried about 30 wrong patterns and it didn't came up the google mail recovery option.
Tried during a phone call to see the files but I only managed to turn on WiFi.

When you say the USB flash drive doesn't work, do you mean the USB port in the phone?
MTP doesn't always work in TWRP, meaning it won't show up as a normal usb drive on a pc. ADB will still work though, you have to set up ADB on your computer, boot into twrp on the phone and use 'adb pull' to copy the files to the computer. On windows you will need to download adb and the drivers, I use http://www.koushikdutta.com/post/universal-adb-driver
I'm trying to install the drivers for adb but I cannot find the right one.
Edit: Also it cannot be detected from boot loader now. I'll try in a pc that already has been connected and worked.
I have adb and fastboot installed already and worked with this and my own phones.
Edit: It seems to be a lost cause the phone fell down many times. Don't bother maybe I'll solder a usb port first... if it is possible with my less than basic equipment.
There are many methods on the following page,
http://forum.xda-developers.com/showthread.php?t=2620456
The way I did it was an alternative version of method 5 while in twrp.
Method 5 - alternatively, Mount system in twrp and delete the file /data/system/gesture.key
If it asks for a pattern on boot just try any random pattern it should let you in. I did this when a version before lollipop was installed but there is no reason it shouldn't work on lollipop as the same file is saved in the same location, just checked.
Using adb
adb shell rm /data/system/gesture.key

SM-A510F : Forgotten lock pattern

Hey guys,
I'm posting here as a last resort before a factory reset.
By the way, let me first say that I'm sorry to post this here, as I know it's SO stupid, what's happening.
I had the same lock pattern for 2 years now, never had a problem.
Last week, it just fell out my mind completely. I've been trying for 4 days straight to remember it.
It's quite a complicated one, with the pattern tracing deactivated so I can't remember the shape and my thumb tried with its motor memory but to no avail :x
The thing is, I extensively use the notepad stock app (Samsung Notes ? Android Notes ?) and I have a **** TON of info I REALLY don't want to lose. And it's not on the SD card, ofc.
I don't care much about the rest, to be honest.
Fun fact, I only synced contacts via the android sync function.
So how can I either remove the lock pattern or access my phone files with an explorer on my computer (I guess I can find a memory file for the notepad somewhere), knowing that :
- Not rooted
- USB debugging not activated
- Not registered with Samsung account
- Android version is the latest available in France for an SM-A510F as I do all updates
I can provide as much as I can to prove my ownership of the phone if needed.
Thank you for reading and maybe for helping.
You have absolutely every right to laugh to my (dumb) face.
EDIT :
Just tried something else. Booted in recovery to try an ADB command.
Since Windows didn't recognize the phone in recovery mode, I selected the option "Load package with ADB" or something like that.
Now the phone was listed in devices on ADB and I tried this : adb shell rm /data/system/gesture.key
Result : error.
Great.
So since the phone was unresponsive to any button, I waited and there was a timeout on the package load.
BUT NOW...
I have a blue screen that says "Error!" and it's completely unresponsive.
GREAT.
I'm off to work, read you soon.
XOXO
