install unintalled system app with adb - Android Q&A, Help & Troubleshooting

Hello friends
I uninstalled the com.android.documentsui package with adb a few days ago
And I really got into trouble
How can I reinstall it?
I have to say that I found the apk file on the Internet, but when I use
Code:
pm install --user 0 android.documentsui-7.0.apk
, I get this error:
Code:
Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package com.android.documentsui signatures do not match the previously installed version; ignoring!]
Can anyone help me? Or say goodbye to document?

I'm not an expert so I don't know if this will help, but Occam's Razor says that you can switch OUT of adb to install & uninstall, and then, after you get out of this locked-up situation, you can try adb again later.
You didn't mention so I need to ask a basic debugging question:
QUESTION:
Did you try to uninstall directly from the phone (without using adb) and then try to install directly on the phone (again, without adb)?
If so, do you get any errors and if so, are they the same or different than what you get using adb?

In answer to your question:
Document software is a system software and can not be deleted or disabled by the user. I deleted it with adb.
In response to your second question:
I could not install it normally and with the phone and encountered this error:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Since I completely deleted this program from the device, I do not understand the reason for this error!

When you uninstall any sys app from adb, still apk will be there.
I guess you may have use adb command like
Code:
pm uninstall --user 0 package.name
In that case simply do this
Code:
pm install --user 0 package.name
replace package name with one you want.
In case you have used command hide instead of uninstall, use
Code:
pm unhide --user 0 package.name

Thanks, I will try this
Make your solution look right
But I think in order for the apk file to remain, I have to use -k (keep data), which I did not use. It is true?

I tested your code and wrote:
Code:
pm install --user 0 com.android.documentsui
And I got this error:
Code:
Error: failed to write; com.android.documentsui (No such file or directory)
I can not understand what is the problem!
Do you know how to solve it?
