Rooting Samsung Galaxy Tab
Z4root is the application that needed to be side-loaded. Was no longer available in Android Market. AT&T does not allow side-loading (installing applications from directories). But to change that, you need root… Here’s what I did:
- Download z4root.apk.
- Download Android SDK
- Connect the tablet, and run ‘adb install z4root.apk’
- On tablet, run the new app.
- Now, in principle, all applications could be installed like this, but that requires a computer every time. So to fix that, I followed the instructions here to reset the permissions permanently. Couple of things:
- I needed root access for ADB to get to the right directory. This involved opening up on the Tab the “Superuser” application, then in a ADB shell, run ‘su’. Click the permission window on the Tab itself.
- I copied the settings.db to /mnt/sdcard, then used ‘adb pull /mnt/sdcard/settings.db settings-orig.db’ to pull it from the phone
- I copied it into settings-mod.db
- I used SQLite Manager to modify the file, then copied it back to the /mnt/sdcard location, then used the ADB shell to copy it back.
- In the ADB shell, ‘reboot’, and it worked.
