[Galaxy S6 Q&A, Help & Troubleshooting] VinzzB:
Hello,

I have a Samsung S6 with android 7.0 running on it. (latest stock firmware) The screen got cracked this week and the digitizer and OLED are not working anymore.

I've got some 2 FA keys in google authenticator that i did not backup. Now i know that i have to keep the QR code safely... but that is too late in this case. I don't want to buy a new screen...

I did manage to get a full backup of my phone by attaching a keyboard with an OTG cable. but this will not recover the 2FA keys in Google Authenticator.

How you can unlock your phone with a keyboard:

1. attach a keyboard with an OTG cable.

2. press the 'esc' button' and 'backspace' button

3. insert your password and press enter. You should hear the unlock sound. (you can unlock with the fingerpint from now on, if it was set)

I did activate developer options before but i disabled it when i'm not using it. So i have to activate it again.

I think i can enable Developer mode blindly by following these steps. The phone needs to be unlocked.

1. typ one letter. This will bring up google search. press backspace and delete (just to be sure it is blank). Now type 'Settings'

2. Press the down key once

3. Press enter

4. press the down key for 10 seconds (this should focus the item on the last option in the list, which is 'developer mode' )

5. press enter

6. press up once

7. press right once

8. enter

developer options should now be enabled.not sure how i can check this tho. I checked if my computer can find my phone. I can access the internal memory because the phone is unlocked.

i asume developer options is enabled... The next step is re-activating debugging mode in order to mirror the screen. But 'adb devices' does not show any device yet. This means 'debugging mode' is still deactivated.

So i'm trying to enable 'Debugging mode' within the 'developer options'.

I searched on youtube to see how the menu looks like in Android 7 on a S6 so i can figure out how many keys i need to press in order to re-activate USB debugging. But i seem to be stuck on this step.

My question: can somebody make screenshots or a video from a samsung S6 (with android 7.0) device with a keyboard attached that shows how many key presses are needed to activate USB debugging?

When i'm in the developer options menu i think i have to press 9 times down, hit enter, then press the right key once and then hit enter again.

Can someone confirm that this is correct?

The RSA keys for my pc were already accepted previously. so that should not be an issue. unless i hit the 'revoke keys' options by accident... (i hope not!)

if anyone knows an other way to activate USB debugging without erasing the whole phone, please tell me. I need access to my 2FA keys. :crying:

edit:

i'm not sure if the steps to enable Developer mode are working. I'm reproducing the steps on an old S5 phone. I now realize that there are internet suggestions when typing "Settings' on the S5 model. I need to press 4x down then enter. hmmm... These suggestions only pops up when wifi is enabled. I can ping my S6 phone. So WiFi is enabled on my broken s6.

---

It would be awesome if someone can record a video that shows me (and potentially others) how to install and run 'SideSync' through keystrokes. on an S6 with android 7.0. SideSync can then mirror and control the screen on a pc..

I'm going to try this blindly for now... fingers crossed

edit2: it seems that SideSync needs a code that is shown on the S6 screen. damn it. Searching for other solutions... :P

Kind Regards,

Vincent
