Lenovo B8000-f Android Update ^hot^ Site
Note to the reader: This device was released in 2013. It did not receive official updates past Android 4.4 KitKat. This post focuses on how to get modern apps running via custom firmware (LineageOS).
Post-Update Tweaks
Once you boot into Android 7.1:
- Disable animations in Developer Options (Set Windows/Transition/Animator scale to .5x).
- Use "Lite" apps: YouTube Go, Chrome Beta, or Via Browser work better than full-fat apps.
- CPU Governor: Set to "OnDemand" to stop the Tegra 4 from overheating.
Steps (high-level)

6. What Lenovo Should Have Done (But Didn’t)
At the time, Lenovo could have:
- Released kernel sources to allow community developers to build stable KitKat.
- Provided a stripped-down Android 4.4 update without Lenovo apps to save RAM.
- Been transparent about the EOL (end-of-life) date.
Instead, owners were left with a tablet that worked fine for 18 months and then slowly became obsolete.
What you lose (The Trade-offs):
- Camera: The rear camera often crashes in third-party apps (the front works fine for Zoom/Meet).
- SELinux: It runs in "Permissive" mode (fine for a home media tablet, not for corporate data).
- Battery drain: You might lose ~1 hour of screen time compared to KitKat.
