I'm trying to update my Samsung Galaxy Tab 3 (SM-T210) to Android 4.4.2.
Right now, it haves Android 4.1.2.
If I try updating using FOTA, it reboots, starts counting, but aborts the proccess in about 25%.
Now I'm trying to use ADB on Ubuntu, got a firmware file (T20XXBNI1_T201ZTOBNI1_ZTO.zip), and tried to "adb sideload <update.zip>", but it gets stuck on 92%.

Does anyone knows if this is expected? It's the first time I try such things.
