Amazon Fire TV low storage fix

Since last week or so, my 1st gen AFTV always pop up a message for low storage. Turned out it was the Amazon launcher cache that took up all the storage.

Here is a dirty and easy fix, root required:

adb connect 192.168.1.101 (change it to your IP)
adb shell
su
cd /data/data/com.amazon.tv.launcher/databases
rm mbcache.db*
touch mbcache.db
touch mbcache.db-shm
touch mbcache.db-wal
chmod 0 mbcache.db*

Now, ls -all and it should look like this:

      Does your ftv has root?

      Yes, it's rooted. I can use the SU to get to the root@android:/data/data/com.amazon.tv.launcher/databaases , I just don't see any response after I input rm/touch/chmod command. nothing happened and i can see the screen as you posted.

      Did you run su first? Use this command to find large files:

      du -a | sort -n -r | head -n 5

      If your screen looks like above photo, then all done and fine.

      Your database/cache files might be in a different location. cd /data and du -a | sort -n -r | head -n 5 to find out the folder. cd into that folder and du -a ... until you find the large files.

      Yes a reboot clears the cache, but it'll become full again.

    How do you undo the chmod 0 command if I want to use the amazon launcher again?
