My Samsung A30 has a broken screen, I’m attempting to transfer all my files unfortunately the phone does not have the file transfer mode enabled so when I plug it in to my PC it’s recognised as a modem.
I’ve attempted to use https://github.com/Genymobile/scrcpy to display my phone so I can perform transfer operations unfortunately it requires USB debugging enabled which I don’t have.
I’ve also attempted connecting my phone to my TV via a USB hub though the phone model does not support HDMI output.
The phone is running as it is receiving calls with it vibrating.
Any thoughts on anything else I can attempt? I’ve already bought a new phone so not too keen on getting the screen replaced especially given there could be other issues.

If the screen is broken and you did not have USB debugging enabled before it was broken, there is nothing you can do to retrieve your data except repair the screen or find a tech shop that has the tools and the knowledge to pull your data directly from the hardware chip itself.
You will not solve this yourself using only software.
Use a USB Type C to HDMI cable to your TV.
The Samsung A30 apparently supports it.
HDMI Alt Mode doesn't go through a hub.
Enable ADB and download.
@Droidriven thanks, fair enough, I've ordered a screen and will attempt to replace it myself.
@Renate To enable ADB I need to enable USB debugging. Also doesn't seem like Samsung A30 supports HDMI output https://www.samsung.com/au/support/mobile-devices/connect-samsung-device-to-tv-via-hdmi/
Oh, sorry, my bad. The internet will give you an answer to any question, usually wrong.
Is there any chance that you can find the hardware serial console on internal test points?
Then you just need to:
Code:
# settings put global adb_enabled 1
If your ADB was previously enabled, then you won't have to deal with the invisible acceptance screen.
If not you'll have to echo the public key into /data/misc/adb/adb_keys
(I just did this on my B&N Glow '21 when it factory reset and it blocked me with a mandatory OOBE setup.)

For one, your solution is not a software solution, which is what I said, that they would not solve this with software alone. That is true and that is all I was saying.
Second, this solution is a hardware approach that the typical user has no experience with, which is why I didn't present them with an option that I am certain they are not comfortable with or experienced enough to attempt, as demonstrated by their attempts with software and unsupported HDMI and then stopping there to ask for help. An answer that more than likely seems more like a risk to them than a solution, isn't really helpful to them. I've helped with users dealing with this issue for years, I've learned that the vast majority of them are not comfortable with resorting to solutions that people like you and I would. With most of them, you may as well be telling them that they can solve their issue by biting a tiger on his ear, they are afraid of the solution. But, I understand, you have a proven, working solution, so you posted it, that is actually good, thank you.
That is why I said to repair the screen or take the device to a tech shop that has the experience and the tools(which requires opening the device to implement a hardware solution, as your posted solution also requires opening the device to implement a hardware solution) to retrieve the data for them(if repairing the screen is not their preferred solution, which obviously isn't). Also, Samsung isn't as simple as B&N hardware, Samsung has some tricky stuff when it comes to hardware, especially their Qcom versions, such as Qfuse(on some nodeld)and other tricky hardware designed to make tampering a real pain or even kill the device with built in components intended to kill the device if triggered. Their bootloader is pretty hard to get past without breaking into the hardware itself also.
Yeah, I know about Samsung, which is why I don't buy it.
In any case, if it's booted to Android, then Android generic solutions will work.
I don't have any idea if a serial port is accessible, but if it were, that would be an easy option.
thanks for the advice guys, @Renate your solution is probably probably beyond my expertise though thanks for your comment, hopefully I can understand it better in future. I'm hoping to use this screen replacement as an entry point into mobile phone repair.

Backstory:
My buddy bought 3 ASUS tf300t tablets online with broken screens. Unbeknownst to us they have this weird firmware issue because ASUS is lame and doesn't care about backwards compatibility. I've been trying to fix these tablets for a few weeks now and I'm just spinning myself in circles and getting frustrated. 1 of them is rooted with CWM recovery so that's the one I'm working on.
The issue:
According to http://forum.xda-developers.com/showthread.php?t=2091233&page=11 I can simply adb into the device copy the proper firmware to it's set directory, delete the old firmware, run the firmware update command and touch will be restored.
So how does one use adb without usb debugging enabled?
I tried through CWM, adb worked, but I can't get superuser to work, nor could I get the touch_firmware_update command to work.
So I downloaded the http://forum.xda-developers.com/showthread.php?t=1893714&highlight=root stock rom with usb debugging enabled. I flashed that rom and my computer brings up the normal TF300t drivers for MTP.
ADB doesn't see any devices...
I tried manually replacing those drivers with the ADB drivers from google because I'm a touch retarded and I thought it would work. My mom says that I'm super smart and really handsome, but I feel like she lies to me.
There's just so many new terms and I've spent so many hours on it that frankly, if search did bring up the answer, I would miss it.
I'd appreciate any help, and if you help me fix it, I'll make a youtube video thanking you in the creepiest way possible.
-Thanks

Short of investing 60 bucks on a docking keyboard, your best bet would be to get a usb dongle that allows you to plug in a keyboard so you can be sure debugging is ticked. Otherwise, if it's enabled and you've installed the proper drivers, Windows should see your device. From there, it's a breeze, if the hardware is good. You don't have to do Youtube. Just stop crying, Gives me the creeps.

Yep, your only for sure way would be a USB OTG adapter or a dock. Heres the adapter in the US for 10 bucks shipped on eBay. This will let you use any regular USB mouse instead of the touch screen
http://www.ebay.com/itm/USB-to-OTG-...ablet_eReader_Accessories&hash=item41700957d7
Heres another for 4 more bucks that gives you Two USB ports :
http://www.ebay.com/itm/Dual-40-Pin...ablet_eReader_Accessories&hash=item3cce7dd4c8
Also you can try giving this a shot ....http://code.google.com/p/androidscreencast/
Its an app that pushes your phones screen to your desktop so you can use a keyboard and mouse on it. Not sure if it will work for you since im sure it needs debugging on, but also worth a shot. I use MyMobiler on mine but it needs to be set up on the device itself first. This looks plug and play but says it has slow refresh rates.
As far as the ADB drivers, Im using the universal drivers found here : http://forum.xda-developers.com/showthread.php?t=2139767 and everything works as it should . Try those out
Oh and one more thing.. You might be able to use fastboot to push a touchpanel firmware zip. This is a different device, but you could try it :

I gave up, but, I appreciate it. I even ended up buying the adapter, ended up bricking the tablets.
morning geeks
you have a phone, which is not able to :
show the display
use the touchscreen
but the hardware is still able of these features :
usb mtp device, as a usb key
wifi network
cell network
and so on..
so you are here, somebody gave you a smartphone, running android, locked, but you can't neither see display or use touchscreen;
but its starting anyway, you can hear the ringer if you call on it;
how would you do, without usb debugging enabled, to use this electronic technology as a specific usage, like a wifi AP or a usb key?
in an other words, what is the method to restore it and to take the control of it?
you just have a usb mouse can be connected on it. but no display.
[this is mainly destinated to avoid throwing several android hardware to bin, cause it can still poweron.]
I have a device that's evidently called an Edge Mini tablet purchased from the prison system while I was incarcerated. Known issues are battery explosions as mine did. All I have is a circuit board in which Device Manager on pc recognizes something briefly and disappears.
I spent nearly $2k on music and would like to find help on retrieving it somehow.
All I know is that it has a custom Android build and and i cannot view the device on its screen, however thr computer reads it.
Much help needed!

I have never heard of the device that you are using, after doing a quick google search it seems that you should probably contact a business called the keefe group. They are the distributors and provide support for that proprietary device.
https://www.keefegroup.com/home/contact-us-105
Here is the User manual: https://fccid.io/2AHUC-EDGEMINI-AA/User-Manual/User-manual-3073167
If all you have is the circuit board , then most likely your chances are recovering encrypted data are not good at all.
Ideally, you would need to boot into the system and enter developer options, turn on USB debugging, allow an external device MTC connection etc., which allows you to connect to your PC.
On the other hand, its an older Operating system, with less secure software. Perhaps, for a technicians easy access the steps I listed above have already been setup. If so, try downloading the USB driver for that device, and then reboot your PC. If the issue is a driver issue, you should now have access to the internal storage and will be able to copy over your files, by connecting the board to your desktop, using the usb power cable. If the PC reads the device, you should be able to see the internal storage by going to this PC, and it would be under device and drives.
Are you sure that your files are not backed up to a server that you can remotely access? Worst case, I would look into that option.
Good luck.
I have a OnePlus Nord N100 that I dropped off a ladder... I ordered a new phone (screen replacement seemed to not be worth the hastle on such a cheap phone when replacement kit was 60$) but would like to re-purpose the device for something as I am very against e-waste.
I would like to make it a security camera. If I can get ADB shell access it should be possible to install termux and run some linux command line utilities for this (i.e. motion and rclone to upload).
Problem is that without screen I cant login and turn on usb debugging. This phone uses usb 2.0 so I cannot use an hdmi display and mouse.
Is their any way I can get usb debugging enabled? I would prefer to be able to get my files off the device but most of it was backed up. Resetting is fine. I would even be down to try to re flash it with a serial programmer or something. Would their perhaps be any serial programming pads I could solder onto?

If you did not have USB debugging enabled in system settings, there is no external way to enable it. Fix the screen, otherwise, the device won't be any good for an secondary uses other than using it as a paperweight or a doorstop.
Hello everyone, I have been reading and respecting you for a long time.
They gave me a Mediacom tablet with Android to repair or throw away as a favor, I'm not asking for money and I'm not a professional, just self-taught. It basically had half the screen where the touch screen didn't work, so in addition to trying with the "pizoelectric" lighter as seen on youtube and various apps, I decided to try replacing the touch screen as well. Once done, the problem remained as it was. I tried to do the factory reset and now I'm stuck in the installation because I can't click on the buttons to finish the installation. I used to at least rotate the screen and run it on the good half. But now I'm stuck in the installation. I also tried to take a usb dongle to attach a mouse to it, but it doesn't see it, also tried on the smartphone, but it doesn't see it anyway. 1. Confirmed that it is not damage to the touch screen. Can I finish installation via adb shell? What do you think is the problem? is it software? Any advice is greatly appreciated.
Thank you
It's hard to advise anything without writing the model name of the device. Adb host will not work when it is not enabled in the device.

The model is smarpad iyo 10, but I doubt it serves as information, since it is probably an Android 9 problem. I thought it was possible at boot to enable a shell and complete the installation or maybe rotate the screen.
Thank you for answering.
The Rockchip A55 RK3566 processor in the Mediacom IYO 10, supports USB OTG, so a mouse connected to an OTG adapter should work.
Which adapter did you use?
The touch screen for the Mediacom IYO 10 is not outstandingly complicated and has no chipset in it. So the touch is controlled by the mother or daughter board electronics, which you probably did not replace when you replaced the screen.

The Otg adapter is from Tek-one to-g-15, it may be that it doesn't work, in fact it doesn't work on the mobile either, I try to change it.
As you said, the touch had no chip, just a connector to the motherboard.
An information that I have omitted may be useful, at the beginning the tablet also had another problem, in some circumstances that I have not explored, the screen or the resolution was resized in half, presumably in the working half. Almost immediately the scaling issue was fixed by randomly activating a gui option in hidden developer mode.
Now, excluding the Otg that I'm going to change, do I have any possibility of continuing the installation via shell?
Thanks for the precious information.
You probably don't have TWRP so you won't do anything with the build.prop file.
The lack of a shell is the result of not enabling debugging in the developer options, available only after starting android.
Look for a working OTG adapter.
Maybe this thread will help you.
