[Q] Backup a broken screen GS2

The screen got cracked and screen and touch doesn't work. The phone boots and works fine as I can see the OS when connected to a TV via MHL to HDMI adapter.
The phone was rooted and has CWM 4.x. I can probably boot to CWM by doing the steps blindly. But once I get into CWM, how do I back up all the data off the internal sdcard?
I read somewhat about using adb command to back it up but unsure about the exact steps to do so. Is it possible to backup everything and restore it to a new phone? Please help, thank you.

I figured it out and did a "adb pull /sdcard" to backup all the data.
Now I need to wipe all the data, but unable to do so. I managed to get the phone in recovery mode (well I think its in recovery), then I did:
adb shell
format DATA:
I get permission denied. I also tried:
adb shell
su
again, cursor blinks a few seconds, then it says permission denied.
please help.

So you can see the OS through MHL but not see recovery through it? If that's the case you could go to settings> privacy> then factory data reset

Thanks, I can see the OS with the screencast, but mouse and keyboard doesn't work. I also have a lockscreen pattern, and I can't get pass it without mouse control.

Probably should check in the screencast thread.
I'm sure they can help you figure it out.

oh, forgot about that..
You could probably Odin to stock blindly since the com port on Odin doesn't come on unless you're in download mode. Just hold the two volume buttons and plug in a USB cable and you should be in download mode.

Help me recover OP3 data

Hi all!
I recently dropped my OP3 and now i have a black screen and touch screen doesn't work. The phone is still on and operating (i tried calling it from another phone and it works). I want to recover data but apparently i have usb debug off and i tried connecting a keyboard with an OTG but apparently i had to activate OTG from phone, otherwise it doesn't recognizes it.
Do you know any method to recover data?
My last chances are repairing the screen myself to avoid the assistence erase all the data, or transfer my motherboard to another OP3, but do you know any other method before these two above?
Thank you

Most likely the connector has become loose (since you have not said anything about the screen being broken) and you can try to reconnect it by yourself.
Another alternative is to see if adb is working and your PC is authorised. If so, you can use the 'adb pull /sdcard' command to copy your data to the PC.
Alternately, search with Google since I remember reading about a method to mirror your screen and then using the mouse to enable whatever you want.

I'll check the connector but the screen has some cracks (tho i've seen screens in worse condition then mine work).
And i can't use the mouse because OTG is not on, on other phones you don't need to give permission to use OTG but on mine you have to,

What about adb? That is the easiest.
I am not talking about connecting the mouse to the phone through OTG. I am talking about using the PC's mouse to manipulate the cursor to the point where you want it on your PC's screen where your mobile screen is mirrored.

I think you are referring to Vysor, but i can't use it with debugg off again. Edit: I see that there are other apps like that but for most of them you have to install them on the phone, i'll search a bit more tho.
As for ADB i tried before with another phone with debug off and adb doesn't see the phone, i'll try with my broken phone but i don't think it will be different.

Just now, I switched off USB debugging in my OP3 and connected it to the Laptop. While the command 'adb devices' does not find the phone, as soon as it is connected, it shows up as a storage device and I can open it and copy data. I think that for this to work, you should have enabled MTP option for file transfer.
Check this on your phone.
EDIT: Check THIS as there seems to be a way though I am not sure that it works on current Android versions since the file locations may be different. Read till the end.

My phone goes in charging mode when connected to pc, and pc doesn't see it.
Did you do that through recovery mode?

No. Tried it while booted.
Now I tried on recovery mode. Still I get it as a storage device and I can copy data.
So most probably your phone is stuck on charging and not on MTP.

I believe so, every time I connected it to pc i had to switch manually from charging to recovery.
I guess my best solution is to buy a screen replacement and repair it myself

Have you tried fastboot flash twrp recovery and then fastboot reboot to recovery

You can try usb c to hdmi adapter , connect to a monitor or tv.
I am not sure but worth trying!!!

From what i can remember, the recovery mode, accessible from the fastboot menu, has a usb access mode.
If worst comes to worst though, i personally have replaced the screen on my OP3, and its not as difficult as it seems or is made out to be. Took me max 4 hrs.

A70 broken and black screen

Hi,
i have a SM-A705FN/DS bumped in a corner with screen broken and black (doesnt turn on). I need to recover data from it but it doesnt have developer options enabled. My problem isnt black screen of death... its broken at all!
I had spent the entire day searching for posts to enable debbuging options through adb commands but... nothing. Also i tried with odin and one clockmodwork recovery but ever fails.
I can enter the recovery mode and i think that entering the second option (bootloader) i will do something, because my laptop is detecting a "Samsung usb modem" but adb command "adb devices" doesnt show anything.
What can I do?
Thanks in advance. Best regards.

Hi,
my house insurance will repair the screen and they told me that it will be erase. At the moment, I just replaced screen for older mobiles (iphones 4, sony, ...) and never, NEVER, got files lost. But now...
I am trying to find a rom with "usb debugging" enabled in order to connect the phone to my computer with adb commands. I had tried to connect with otg hdmi but nothing is showing up on my tv (my P20Pro is showing perfectly).
What can i do?
Thanks in advance.

Thats a very wiers situation but i have an idea
Have you ever used or setted the link to windows option up?
Cause with that you can start sharing the screen to pc and it just works when u already used that before ur screen broke
Otherwise i have no advice for the adb as i never needed to use adb for recovering my data
Good Luck

Hello, I have the same problem. My screen is blank but hearing notifications on my phone. As phone is under warranty, they might replace the unit and I would want to recover my data.
Also searching on how to enable usb debugging via ADB, but not sure if below (Option 2) will work. Still gonna try it on weekend on my freetime.

i have samsung A70 and for months experiencing black screen of death on and off , rebooting etc, found solution today. removed phone from the magnetic phone case i purchased 10 months ago and phone is working perfect,

I drowned my 5T. Touchscreen doesn't work. I need the files!

I accidentally drowned my phone. It powers up to the point I need to give my password to unlock it. Unfortunately the touch screen is dead. I have ADB installed to my laptop but I don't know how to get access to my files. Any help is so welcome right now, I don't even have a replacement phone.

You could try using your phone with computer mouse and OTG cable.

Your screen works but it doesn't recognize touch, right? If so, you can just enable MTP on your phone with mouse and then connect it to your laptop and access the files from there.
And no, I don't think any mouse require software to work if used with OTG cable.
E: https://www.androidcentral.com/10-basic-terminal-commands-you-should-know
You can try adb push/pull method though. Haven't done it myself so I can't be much help with that.

Well it used to work, not right now. It vibrates sometimes when I press the power button, so it's not 100% dead yet. So as soon as I connect it via OTG I will have the option to access it? Interesting...

If your phone boots up and you can see your screen working normally except for the touch part, then yes. But if you don't have OTG cable or mouse now and you have to order them, you might want to try those adb commands in link I edited to my previous comment.

I'll try to use the ADB as I don't have an OTG cable. I'll try it now, thank you.
Edit: It won't communicate with the device with 'adb devices'. I guess I'm in trouble...

Oh, that is actually a bad sign. I was wondering if you had your phone decrypted by any chance so you could've just booted into TWRP and copied internal storage to your laptop from there.

I'll just let it dry in rice for a couple of days and will try several stuff again. Ill get back as soon as I have news. Thanks mate.

I do not know how high your geek-level is, but I would recommend booting twrp, decrypt the data partiton with adb and pull the complete data partition to the PC:
1. Get a bootable twrp e.g. fastboot boot twrp-XX.img
2. adb shell twrp decrypt <Password>
3. adb pull /dev/block/dm-0 ./decrypted-data.img
(Credits go to stackoverflow)
If this does not work I would attach an USB Hub after booting into twrp and attach a mouse and a storage device to the hub. (And a keyboard)

Question Display damaged - how to rescue pictures with adb?

the son of a friend crashed the display and it is now black and cannot be used. How to save the pictures stored on the phone? Does ist work without root with ADB?

Connecting your phone to a pc should enable you to see all the files in the phone, however, you may need to change a setting or so first, and if your screen is black, that's going to be a harder thing. You can try unlocking the phone (if your touch works at least, even if you are blinded by the black screen) and connect it to your pc, hopefully it will connect, if not, search for a guide on yt about how to connect the phone to your computer via adb and try to memorize how the UI looks and where to touch, also you can try to memorize how to access to screen cast, that will make things easier, if your touch does not work, you'll need a mouse or so via otg to do that, let me know how it goes

thank you for replay. I thought that there is an adb command like adb connect copy the picture folder but this is very difficult if he dont enable adb debugging.

yeah, will have to see how the ui looks and try to make the same, it should be accepting a prompt on the center of the screen (as seen on yt videos) or slide down notifications to enable usb transfer (as seen on yt videos too), for now I don't know anything else to do, let me know if he has a usb mouse and the otg adapter for futher help, I could record the steps to enabling that using the mouse on a black screen.
