[SOLVED] - Manually enable adb debugging from recovery

[workdowg]

First off, this may seem a noob question, but I am definitely not.

I have an Iconia A200 that now has a broken lcd screen. No display, no touch. I am able to get into the tablet from TWRP via adb, but not from Android (Jelly Bean). It seems I never enabled usb debugging when I installed the custom rooted rom.... I can access the file system and modify anything... Which files need to be modified to enable debugging in Android? Here is what I tried:

Added to default.prop and /system/build.prop

persist.service.adb.enable=1                                                    
persist.service.debuggable=1
persist.sys.usb.config=mtp,adb

Edit: Must have had typos... It now works.

First, find the folder that contains the adb.exe file.
Then, right click the folder and choose "copy as path".

Then,

You can open system properties,
Click on environment variables,
On the System Variables window, click on the path variable, then click Edit,
On the menu that opens, click new,
And paste the clipboard and click "Ok".
Close all the variable windows.

You should now be able to open a cmd window anywhere and ADB and Fast Boot should work.

I hope that I explained this well enough.
Enjoy,

Hi,
Can you maybe help? Because I have nearly the same problem. I have a Huawei P20 with a broken screen, the touch does not work and I have a password and therefore I cannot unlock it, I would like to be able to get all the data back from the phone and I have tried in many ways how to do it without being able to use it and the only solution is do it through a computer, I have already tried to activate usb debugging with a program, only it shows me the notification but I can not approve, I checked if there was active ADB but it says it is unauthorized and now I wonder if I should send the phone in recovery mode or fastboot mode so that I can control it from a pc or somehow receive the data, the question is how can I do? Is it possibile to enable adb in recovery mode? I have no idea how fastboot or recovery mode can be and whether it will make me lose everything or not so I would like to make sure by asking an expert, I would be very grateful if you could help me.
