Data Recovery From Locked Device - Device Repair

Phone: LG G2 AT&T version (D800), unrooted, stock (no custom recovery), wifi off (but phone will automatically connect to home network if wifi can be turned on), not sure if usb debugging is on
What exactly I'm trying to do: get files and data from my phone to my PC (e.g. photos, contacts, notes, music) for later transfer to a new phone.
Details of the problem:
- The phone is pattern locked.
- The screen is cracked and totally unresponsive to touch.
- Upon pressing the power button or USB connection, the screen displays the lock screen. However, only about the top third of the lock screen is visible on the lower part of the screen; only the top row of the lock pattern grid is shown.
- Upon USB connection to mouse via USB OTG cable, the screen displays only the first frame. That is, it will display where the cursor was when the display was turned on, but not any subsequent movement of the cursor.
- Upon USB connection to PC, the phone enters MTP mode. However, when attempting to access the phone's files from the
PC, nothing is displayed, because the lock screen has not been bypassed.
I'd very much rather not let go of the data on my phone, so I hope someone can help. Any thoughts?

Get a micro USB to OTG cable and connect a wired mouse. You can then use the mouse to draw your pattern and unlock the device. Then connect to PC and recover your data.

Thank you for your reply, but I've already tried that.

At this point, the only other thing I can think of is those 5-in-1 OTG adapters that allow simultaneous mouse input and HDMI output, so I can see where my cursor is pointing via TV. The thing is they're hard to come by around here. They're not exactly cheap, either.

Depending on the method required for your model number, you can try rooting and/or flashing custom recovery, use the custom recovery to create a nandroid backup and extract the data from the backup(backups made in TWRP recovery are almost impossible to extract valid data from), or while in recovery you can try using adb to pull the data you want or even do an adb backup then extract the data from the adb backup using something that can extract .tar/.rar files. You could even use adb with root to delete/modify the data stored for lockscreen then you can probably connect to PC normally and transfer whatever you're after.

Ways to enable USB Debugging mode

Is there any (by all possible means ANY) way to enable USB debugging ON other than turning it on from menu.
This is situation, I got my self a SGS I9000 (had it earlier, now I am proud owner of Galaxy Note) for a bargain (30 €), thing is it is broken. It has fallen on the floor and now there is no image on the screen (touch is not active and sensitive, but soft buttons are sensitive to touch). I know one thing for sure, the phone can be turned on and can use sim card (someone can call me on the phone and I hear the ringing, so I know that phone works only I can't see anything on the screen or interact with it). The corning gorilla glass is not broken, but yet there is no light on the S-AMOLED. I have also opened the phone and all connectors are on the place (please don't tell me it will void my warranty, I wouldn't want it any other way). I figured it to be only a screen replacement fix, but until I have the money for new screen I want to do next thing:
1. Somehow to enable USB Debugging mode
2. To install things through ADB (but I need Debugging mode for that)
3. To put some application (there are many) to stream (screen streaming) what ever is on my phone to pc, so I can control it over pc (ubuntu linux).
Does someone know of some method for enabling USB Debugging in this situation?
I thought of some solutions but I don't know are they applicable at all:
1. Some script that can enable usb debugging when put on SD card
2. Somehow to turn it on with adb or over usb cable
I think the only way to turn USB deb- mode on/off is via menu. There seems no widget like f. E. For 2g/3g.

Need to recover my data from malfunctioning phone

My screen has been shattered but still functional for months now, but the phone finally gave up on me. The phone currently does the following
I took the battery out and put back in. I try starting the phone and the at&t tune plays as usual, as well as the notification LED fading from light blue to dark blue over and over and the two touch keys light up but the screen never comes on or lights anything at all. Also, the blue notification LED continues to fade in and out and the touch keys stay lit up as if the phone is constantly trying to boot.
I plug it into my laptop but it does not appear in the device and drive folder. One thing I did discover is that when I open up Computer Management (Windows 8) and go to the Device Manager tab, and then the Portable Devices tab and it does appear as "samsung mobile mtp device". So I know the phone is making connection with the computer and vice versa but I need help trying to copy all the data to my laptop. Any help will be greatly appreciated.
In my case i attach Samsung to hdmi adapter to check - what messages are displayed on the screen if any. Also try to boot in recovery, if it present and make backup from there - not sure if hdmi signal will work in such case. Also you can re-flash firmware, that does not wipe user data - but still risky.

Can't get any data out of my phone after screen problem. Please Help

Please. Please help me out to get my files from my damaged screen P20 Pro
To be honest I'm starting to hate those HUAWEIS... It have done the same thing twice in a row, this time I was more prepared when last time but still same thing happening, I cannot connect it to PC or even TV thats means I can't get anything out of it :crying:
This time I am 100% sure I had USB Debugging enabled, also HiSuite is also was installed on my phone I just didn't use it. Now when I really need it connect it to my PC it doesn't work! No matter what I do... That is super annoying as they made very simple thing, super complicated and annoying...
- HiSuite doesn't find my phone and keeps popping messages that I need to enable USB Debugging even when its already enabled.. It also gives me message sometimes that I need to install HiSuite on my phone as well but its already installed.. I had checked it trough my PC via Google Play and it says its already installed. Totally useless app if you having screen problems.. I also tried “dr.phone” which cannot find my phone too and few other cant remember the names but unsuccessfully too
The worst thing is that before damaging my screen it was able to access files I was also able to use my Type C HDMI adapter without any problems on TV and Projector but now it doesn't work too... What the hell? WTF is wrong with that thing? The only reason I can think of is that before connecting it to PC or TV I have to unlock my phone first for some stupid Huawei safety reasons and now when I cannot do it because of my screen problem it doesn't connect to anything? If I am right, is there is any way go around that, take off the screen lock without resetting whole device??
On top of all this super annoying bull**** I have found on another Android device which Im using now that all the contacts I saved with my P20 Pro wasn't actually saved into my google contacts at all and all my new contacts for over half year are gone too on all other devices, for some stupid reason it didn't saved them to my google acc even when I am always saving it that way. I never had such a problems with any other devices in the past and I am android user over 7 years.. This phone can get really annoying in some situations, it does what it wants
Can anyone help me out on this one? That would be Amazing :good:
Use a kB to type your pin unless the screen works..
Then copy out..
If you can't turn on usb / hdmi then you'll never guess it..
kB over usb c is your best bet mate..
End of..
Hard times man.
OR....
You get the repair guy to do it whilst you're there lol..job done.
which part of your screen is damaged? the touch or the display or both? Not able to do something you really want might be really frustrating. If I were you, I'd do this way.
I'd plug-in a USB-C hub ( with USB ports for keyboard/ mouse combo, another USB port for storage device, and a HDMI output). Plug-in my flash drive, mouse/ kb, and the monitor (or TV).
the phone will instantly switch to the desktop mode and you will be able to use the keyboard/ mouse and able to copy the files to the flash drive you plugged in.
Maybe you'll need one of those USB-C adapter with power pass-through.

Hey! I have a similar condition with OP. Thing is, I have a USB-C to HDMI connector, and I tried connected it to my monitor. But it's not automatically switch to Desktop mode, instead my phone screen is displayed in my monitor. The thing is, I have enabled password requirement after reboot, and I can't type the password even with a keyboard or a mouse (I was guessing the numpad pattern hundred times, and just click the areas).
So here's the review:
1. Screen cracked
2. No display
3. Touchscreen not working
4. ROM EMUI 8.1
5. Bootloader LOCK (No root, no custom recovery)
6. USB Debugging disabled
7. Password authentication after restart is enabled
8. Can display the screen on my monitor via USB-C to HDMI
9. Mouse and keyboard seems to responding, but not work when typing my password, the screen just freeze when I tried to do that and nothing happen
10. HiSuite acknowledge my device but can't do anything because I haven't allow USB debugging connections.
11. Data not sync to Huawei Cloud
I will not repair the screen because it's $250 exc. labor cost in my country, I preferred save my money to bought another phone. I want to access my data on the phone, Any suggestion?

Thank you for you answer mate. I ordered adapter and the keyboard but some reason it still didn't do the trick. But it does work on other devices straight away. Strange... maybe again some stupid huawei security thing.. I will try dock option, its my last chance :crying:

Thanks for your respond :good: Im not sure about touch screen, I dont thing its working but I can't fully check that at the moment, as for screen its completely dark. You think so? I just ordered type c dock, hope it will do the trick, as keyboard alone with adapter doesn't do the trick :crying: so dock is probably my last chance. Thanks for the advice, I hope it will work

You may need to select something on screen to allow it. Does video come up? Or do any peripherals work?
Are you powering the hub?
Wired or wireless KBM
My wireless one in work, didn't work for me, whereas my wired ones did.
Are you on emui or a custom ROM?
Tbh custom ROMs would probably have more luck from experience.
Did you alter the default usb mode from charging to anything else?
That may also be causing an issue..
Does any input work at all on the phone ? Could you try by measuring input on an identical device then touch the exact part of the screen to unlock it??
I've been here before, but it is starting to look like a lost cause pal.

It looks like this phone does everything he can to keep my data locked :laugh: I connected it successfully via Type C Hub (Good recommendation btw :good::good For some reason my old type c hdmi adapter just doesn't work after screen crash
So finally I have got my hdmi signal back, I can see my lock screen now which is a very good sign, mouse and keyboard works too but now I got another super silly problem which now makes me look like this peace of **** is laughing out of me
I tried connecting my phone to TV and Projector, I can see my lock screen fine but once I push Space on my keyboard or scroll the screen with my mouse to unlock the screen I lose my screen connection straight away...
I tried entering my code on blank screen, pushing enter etc... but nothing happens or if it does my screen is completely dark and I can see nothing, I push on/off button twice and I get back my screen connection back with my lock screen again asking for same code Seriously wtf?
It looks like that moment which lets you type the password in can't be transmitter on my tv/projector for lets say some resolution issues... just guessing but my code entering on blank screen doesn't look like is doing anything either
I have an official Rom without any tweaks

Disconnect either the mouse or the kB. Might be too much power. Are you powering it?? Change cable. Change TV.
No it doesn't have external power source. My current type c hub, doesn't have this option. Only Hdmi, 2x Usb 3 and sd & micro usd slots. Is there is anyway to add it now externally?
I have tried it already with single kb or mouse. Even connecting my wireless kb just with usb type c adapter with no luck. Once I come back home today I will give a try with only Wired Keyboard connected. Haven't tried that yet

it's better to use USB-C hub with power delivery (i.e, u can plug in your charger to the hub).
I also tried your scenario at home last night. I plug-in my keyboard, mouse and HDMI cable to the hub, then i plug-in the hub to my phone while the phone is locked. first, there is nothing. No signal.
Then i press power button on the phone, I then saw the mirror of phone display on the monitor.
When swipe the mouse to reveal the unlock screen, yes, the monitor suddenly lost the signal, but just continue typing in the password correctly. The phone will be unlocked and u will get back the HDMI signal on the monitor.
then pull down the notification panel and activate the EMUI desktop mode. That's it.

Thank for your respond. It's sounds simple and obvious but for some reason I can't get through that bit for some reason, I even started thinking if google could changed my password but thats very unlikely but its acting as it is, as I don't know how can I type my password so many times and it still wont pick it up
I will give another good try today once I get back home, it does look like I tried that already but will give another try. The thing that you lose signal at code bit as well tells me that it not just happening for me and that my kb and mouse should be still working at that time as i though I could be getting full disconnection at that time.
Do you need to click Enter to confirm typed code in? O does it unlocks straight away after correct code is entered? Tried both still
Hi did you manage to get this sorted? I'm experiencing exactly the same now. Tia

Did you manage to get anywhere? In the same boat. Can get lock screen up using HDMI adapter, but when I unlock, the screen goes black and the monitor says no longer receiving signal and goes into standby mode.
I have the same problem - even with a active USB-C hub...

OK. This is how I got my P20 Pro to work.
- I used a generic USB-C to HDMI Adapter. Mine was the Baseus UCN3277.
- Screen Broke completely
- Touch not working
- Fingerprint not working
I just used a wired cheap HP USB Keyboard connected to the USB-Adapter. Using a wired Mouse made it not work for me. I think this draws to much power.
Connecting power to the USB-Adapter also made it not work. (This might be just for this Adapter)
Remove all Sim cards! I had one in the second slot. This made it not work.
This is how it works for me:
1. Connect the USB-Adapter to the Phone and the TV
2. Press the Power button on the phone -> Screen appears on the Monitor
3. Press Space -> Monitor goes black (seems to be some security feature from huawei)
4. Despite the black monitor, type the Password on the Keyboard (I did not use the numpad)
5. If the Password is correct, your in at this point
I used teamviewer to control the phone, so that I could confirm the RSA Fingerprint message, when I want to use adb on the PC.
Hope this helps for people with the same problem.
I am having unfortunatly the same problem here. I did managed to get my phone's screen on my monitor for only seconds (sometimes scretched all the way to 16:9 aspect ratio), but often just black screen or a grey screen with the time and a unlock icon beneath it.
Strange enough it all works right away on my newer Samsung. I tried different mouses and HDMI cables. Going to try a different monitor or TV aswell. Anyone other suggestions?

i have usb hub with hdmi and power delivery + extra usb ports for mouse/keyboard...
can't get pass the gray lockscreen with clock and lock icon - when i press space on the keyboard, talkback says it requres a pattern code which i have to guess where to draw (or so i think)...
can pattern be entered via keyboard's numpad? (like a phone numpad where 1 is a top left corner and 9 in bottom right corner)
Whoa, thanks for this thread. Same problem here, but with my P30.
I only used my mouse before, but with my Sidewinder keyboard it worked. I had to touch my phone, then put in my password and now i have acess to my old phone and safe all the photos. THANK YOU!!!
I used this hub and connected it to a normal usb c power supply https://www.amazon.de/gp/product/B07RQLF6M8/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

were you able to put in the password with your keyboard or did you use your phone. My screen is broken and unusable so I'd have to guess the password?
I have the same problem with my Mate 20X. the phone feed to the monitor freezes or just goes blank as soon I swipe/unlock the phone to put in my password. I tried different combinations with my USB-C hub (powered, not powered, only mouse, only keyboard, both) but it still doesn't work.

Boot powered off device directly into Fastboot mode

Hello,
I'm attempting to use hardware key combinations in order to boot into Fastboot mode, e.g.. Power + volume up & power + volume down.
The phone is unresponsive. But the phone boots normally when only pressing the power button.
I've read the tutorial about launching Fastboot through a PC connection here: https://forum.xda-developers.com/rog-phone-2/help/howv-to-phone-fastboot-mode-screenshots-t3966727
But in this case, that wont be an option since my display doesn't work, hence there's no way to accept ABD-permissions when prompted on the phones' screen.
I was initially trying to pull all the data from the phone through ADB. When I realized I hadn't accepted my PC's ADB permissions on my ROG Phone, I had to rethink..
So I thought I could plant my PC's RSA-key (for accepting ADB) in my ROG Phones storage through Fastboot, just pushing the file.
I was dumbfounded when I discovered my ROG Phone 2 to be the only android device I've owned, which seemingly doesn't allow for a raw manual boot into Fastboot? CAN THIS REALLY BE THE CASE?
Any input would be highly appreciated
EDIT: I've ordered an USB-c hub for inputting kb+m & HDMI, which should allow me to accept the permissions. Although some of the data I'm trying to reach are time sensitive, any second rescued would be of value!
Similar problem
Hello,
I have a similar problem. My display is broken but the phone seems to still work. I bought an USB-C hub, but when I connect the phone to the TV (via the side USB port) it only shows a white "Asus rog" logo for a few seconds and then vanishes. When I click the mouse the logo reappears again for a few seconds.
Did it work with the hub you got? Do you have an other idea? I need the data that ist sadly still on the phone.
Thank you for your help.

I did work with the usb-c hub. Never saw any white ASUS ROG logo, I'm not sure what's going on with your phone. Also I later replaced the screen third-party, since ASUS charges a lot of money and insists on factory reseting the phone. So you could always do the latter if nothing else works. Send me a PM if you want the display I got.

Broken Screen, No display, How to mirror on monitor using USB-C?

i got my phone screen broken. using screen mirror i was able to use factory reset, as touch was working. Now phone is at some initializing screen. how to mirror phone at this stage. as i cannot access settings at the moment. neither i can enable 'developer options'. because phone is not ready to use. earlier i was able to connect phone to monitor using USB-C. and used phone's blank screen as touchpad. at this point 'adb devices' is not detecting phone.
