Your tablet: Android 4.2.2 (original firmware) — a great candidate for upgrading straight to TWRP + LineageOS 14.1, no need to root the stock ROM first.
Progress0/26
This is 2013 hardware (Intel Atom, 1GB RAM). Even on Android 7.1.2, expect much better speed and app compatibility than 4.2.2 — but don't expect modern-tablet performance. Take it one step at a time so you don't risk bricking the device.
1. Download What You Need
2. Prep Your PC & Tablet
3. Flash TWRP
4. Install LineageOS (from TWRP)
