so as you may noticed catlog /logcat/ alogcat and such are not working properly or at all.
that is because google added a new permission request from apps which they don't usually request.

but alas, there is fix, if you're working with one of the latest versions of JB (quarx or epsylon3 it doesn't matter) you can fix it by simply by following the next steps:
1. make sure your'e phone is rooted and has superuser or any other permission manager app (superuser zip flashable can be downloaded here)

2. enter the app drawer and enter the "terminal emulator"

3. gain root permissions by typing :

wait for the notification about permission allow/deny, and allow it.

4. now you give permission to the program you want by writing the following line:
pm grant [programs name] android.permission.READ_LOGS

(the upper case /lower case is important)

I.E for catlog you should type:
pm grant com.nolanlawson.logcat android.permission.READ_LOGS

now your logging app should work fine, enjoy!

Here's a way to make all log reader apps work instead of going one by one:

su: "chmod 04755 /system/bin/logcat"

or open root explorer, navigate /system/bin/logcat, long press logcat and select "permissions", then check the box "Set UID".

Both ways require a reboot after!

Hope this helps, thanks to ChainsDD for this!

Thumbs up
Thanks, really thanks.

I use aLogcat and the code that I used was
pm grant org.jtb.alogcat android.permission.READ_LOGS
You can find your logger program accessing with any root explorer the folder "data>data" and look for the name of the folder that contains the name of your app within. I looked for it because I'm not using the same app that you used, so I opened the "Root Explorer>Search" and searched for "logcat". So I found the folder "Data>data" and tried using the name of the folder that was "org.jtb.alogcat" and worked.

Thanks very much, nice job.
