If you are looking for stock Android 4.1.2 Samsung Galaxy Tab Plus firmware but want it deodexed, going for this firmware makes sense. It is based on latest official firmware and comes in ODIN friendly TAR format. After installation, you can re install root, busy box and Xposed if that is what you are into.
Installation instructions:
1. Flash "MF1 STOCK" with Odin
2. Install CWM or TWRP recovery with Odin (files must be unzipped first)
3. Flash "MF1 DEODEXED" in recovery
4. Root or re-root with framaroot app (open app, click "Aragorn", reboot, & you’re done).
