How to get into the data folder without root and bootloader?

Question

Android

So a program has been created. It encountered an error while running. This error is written to the db file. Now I need this file .
To get root , you need to unlock the bootloader - which leads to data loss .
Tried to get the file in different ways. One such option was the Helium program . Having made a backup of the data of this application in it, saved them on the disk. But when I opened it, I realized that it wasn't.

Answer 1

Turn on USB debugging - and pull it out with a debugger. The debugger can run as root. In general, all program errors are written to logcat, which is available without root rights. Perhaps internal errors are also duplicated in logcat.

Answer 2

We turn on debugging (Many where it is enabled by default)
from the PC, open ADB,
see if the device has determined the command adb devices
if there is then this:
and to get the file we writeadb pull /полная_путь/имя_файла.db D:/hawk798

Answer 3

Excuse me, but this must be done from the command line, right?
