Weird brick(?), phone not fully responding - data recovery before hard reset

Hi,
I have stock Marshmallow on my LG G4 and it somehow just stopped responding. At the startup there is an "android.com.phone stopped working" popup. After clicking OK, it dissapears and the phone doesn't respond for any unlocking attempts. After triple tap, the "magnifying lense" works and thats basically it. Before performing a factory reset I would like to get my data(photos, videos, possibly messages) backed up. But after connecting USB cable it is connected with "Loading only" option. I can't change it to mass storage or MTP. The phone works in background, I can see once in a while new notifications about updating apps etc. I tried using Safety Mode, same things happen.
Is there a way to change USB option remotely or perform a reset without losing all data? Since I never used USB debugging on this phone, I assume it is disabled.
Thanks for any help.

Broken screen and digitizer, enable cast to chromecast with USB keyboard

Hi guys,
I'm in trouble with my OP3T and would really appreciate your help here.
I dropped the phone to the ground and broke the screen and digitizer
I would like to cast the screen to my chromecast to recover my files and maybe later repurpose the phone as a media player through a displaylink adapter.
I have connected a USB keyboard and mouse and can interact with the phone.
Can someone guide me through the steps (keypresses) to enable the cast to my chromecast?

Just login into your One+ account , demand an RMA, follow the instructions and for around 120 euro you will be all good within 2 weeks with a fully functional phone.

Yeah sure I thought about that but I've been a fool and bought the phone on gearbest, hoping to save a little bit at that time...
As the phone was not bought on the oneplus website, it's a bit tricky for the warranty.
Furthermore, I wasn't aware that it was a model made for the Chinese market so the 4G reception has always been horrible here in Europe.
The local repair shops are asking 160€ or more to replace the screen, it's not worth it especially knowing about the non-existent 4G.

Ok I managed to cast another phone to my chromecast using only the usb keyboard/mouse... but I guess the menu structure is not the same on the OP3T as that doesn't work.
Here is what I have thus far:
- Unlock the phone with fingerprint
- Open the app panel with the mouse (move to the bottom of the screen then drag it up)
- Type "param" > this will filter the list, only the parameters app will remain
- Press TAB twice to highlight the parameters app
- Press ENTER
The next part is tricky but doable:
- Move the cursor at the top right of the screen
- Move the cursor slightly down and left and click on the search icon (you have to fish for it a little bit, but you can hear a "click" once you've succeeded)
- Type "cast"
- Press TAB
- Press ENTER (that brings you to the display menu)
- Go at the bottom (Press the down arrow until you stop hearing click sounds)
- Press ENTER to select the cast menu
- Press TAB to select the chromecast device (only one in my case)
- Press ENTER to start casting
I would be very grateful if someone could try on his OP3T and tell me what differs and what key sequence I should press :good:

Hi bronderb,
Yes stock rom (rooted).
Unlocked bootloader and TWRP if that matters.

If your version of TWRP has USB-OTG enabled, then you can boot into recovery and use your mouse to take a full backup.
TWRP also enables MTP and you can retrieve the backup to your laptop.

Except I can't really use the mouse to create a backup in TWRP as I don't see the screen :laugh:
I did recover some files with using ADB while in recovery mode, but I didn't manage to do a full backup.
And that won't help me in re-purposing the phone to play prime video and local media files through a displaylink adapter

For a full backup, you can create an openrecoveryscript which is recognized by TWRP and upon boot into recovery, TWRP will automatically make a backup as specified in the script and you can pull that over MTP.

It's cheaper than that. To be more precise it costs 88 EUR. Just sent mine last week

I still would like to reuse the phone as a media center.
If someone can guide me to enable chrome cast or setup a display link adapter without replacing the screen...

USB debugging mode issue with several apps

Sorry for my English.
There are a few apps where you are not allowed to use USB debugging mode while working with them (Fate/Grand Order, Fortnite, some banking apps, etc).
Two days ago I've run into a problem with Fate/Grand Order. I turned on the debug mode and after that turned it off. However, the app still throws an error about USB debugging. The support team said that I should contact my manufacturer. I've found a theme on Xiaomi forum (can't post a link because of anti-spam) about this problem. Some users with POCO F1 have this problem too.
The only solution is factory reset.
Does anyone have the same problem?

I've tried this but nothing helped. I flashed 10.0.3.0 ROM and now everything works perfectly even after enabling/disabling USB debugging mode.
My friend also has Mi A2 Lite so I asked him to check this bug. He installed the game (he was using ROM 10.0.3.0) and after turning on and off debug mode everything worked fine. Then I asked him to install new 10.0.4.0 firmware and check this bug again. He got USB debug error even after disabling USB debugging.
So new February patch makes unable to play some games (such as Fate/Grand Order, Fortnite and so on) where it's not allowed to use USB debugging.

You need to disable developer options for fortnite to work!I'm pretty sure that the other apps also require you to disable developer options

I know, as I said earlier, it doesn't work. If you try to enable and disable USB debug for the first time on 10.0.4.0 you will get an error about USB debug.
On 10.0.3.0 everything works fine. Seems USB debugging in 10.0.4.0 firmware is kinda broken. All applications detect it as turned on.

You can unable it in Dev options.
Btw you can't run Fortnite on Mi A2 Lite, check sys requirements for the game.

If I disable it nothing will change. There is a bug in 10.0.4.0 firmware. USB debugging doesn't turn off completely. I'm sorry, but did you even read my message?

Ok, I know 3 people who have the same problem. Does anyone here have the same problem with 10.0.4.0?

broken screen

Hello,
My screen is damaged and is just black but the phone itself still works. I can still use android auto until I fix the screen.
Is there a way I can retrieve texts from the phone to the computer?
Many of the programs I looked at require confirmation from the phone and I have no way of clicking allow. Is there any way to get the messages?
Thanks

Is your usb debugging enabled?
Also does the touch works?

If you are interested in messages, contacts and call history only, a simple solution is to check your Google account. Obviously you should have the account on the phone and should have selected to back up to that account.

adb might help
-> moved into new thread, sorry for hijacking this one

It was enabled before this happened.
The fingerprint button works, not sure about touch since I can't see anything to check if it works.

I know I can get my contacts but how can I get messages? I only see messages for web, but you need the phone to scan the QR code.

If debugging is enabled and you have allowed your pc for adb debugging on your phone, you can use this software,
https://github.com/Genymobile/scrcpy/releases/download/v1.12.1/scrcpy-win32-v1.12.1.zip
The official github repo link: https://github.com/Genymobile/scrcpy
Download and extract the zip, open command prompt in the extracted folder, connect your phone to your pc (debugging must be enabled, and pc must be allowed) and type scrcpy on cmd.
P.s you can check if the touch works by touching the screen and checking the response. You know how to turn on the flash. Try turning it on. This can help if your pc isnt allowed debugging on your phone. You get a prompt message on your phone to allow this pc. You can guess where the OK button is on the screen and try pressing it.
Sorry for long reply, but this is what i did.

Xiaomi 5A (MDG6) - How to unlock without losing data. USB debugging off

Hello everyone.
I've been digging through forum to find a solution to my problem. I have forgotten lock screen pattern to Xiaomi 5A, I would keep on going and try to enter and remember which combination I used, but every attempt is followed by 4min lock up. I've stored there a password in a notepad which I must retrieve.
I have an access to MI account. USB debugging mode is off.
I've tried few things already.
Method 1#:
https://forum.xda-developers.com/t/...ing-android-password-pattern-face-pi.2620456/ - Doesn't work, as USB debugging mode is off.
To enable usb debugging I found one method. Using MI unlock software LINK to enable fast boot and then follow with the steps from above. However on MI UNLOCK I'm showing "After you unlock the device, it will become less secure. Your personal data may be leaked or lost.". Could any one confirm that this process won't wipe the data?
Method 2#:
Secret codes - none of them work.
*#*#6484#*#*
*#*#3646633#*#*
*#*#4636#*#*
Your help will be greatly appreciated and the right solution rewarded. Please let me know if you have any ideas how to access the phone.
Thanks!
