Lenovo TBX704F (Tab 4 10) Android Update 2021: The Complete Breakdown

Published: March 15, 2021 | Updated: December 2021

If you own a Lenovo TBX704F, you are likely holding the Wi-Fi-only version of the Lenovo Tab 4 10 (model number TB-X704F). Released in 2017 with Android 7.1.1 Nougat, many users have been anxiously waiting—and often confused—about the device’s software future. This article covers everything you need to know about the Lenovo TBX704F Android update in 2021, including official releases, security patches, custom ROM alternatives, and what to expect going forward.

8. Should You Keep Using the TBX704F in Late 2021?

Yes, for basic tasks:

• Web browsing (Firefox, Chrome)
• YouTube (app version 2.18.xx or older)
• E-books (Kindle, Libby)
• Offline media (VLC, MX Player)

No, if you need:

• Modern banking apps (many require Android 9+)
• High-end gaming (Genshin Impact, COD Mobile)
• Biometric security patches

Recommendation: If you are on the July 2021 security patch, the device is safe for daily use until mid-2022. After that, consider upgrading or flashing a custom ROM. lenovo tbx704f android update 2021

9. Conclusion

In 2021 the Lenovo TB-X704F received limited and uneven Android updates: security patches appeared sporadically while major Android version upgrades depended on SKU and region. Enthusiast communities provided pathways to newer Android versions, but those involved technical risk and potential functional compromises. Owners should first seek official OTAs, resort to manual methods only with careful preparation, and consider device replacement when long-term updates are needed.

Notable 2021 Security Patch Dates for TB-X704F:

• January 2021 Patch: Addressed critical Bluetooth and Wi-Fi vulnerabilities. Delivered via OTA as build S001037.
• March 2021 Patch: Fixed a Qualcomm DSP vulnerability (CVE-2020-11201) affecting audio processing.
• May 2021 Patch: Minor system stability improvements and Google Play System Updates.
• August 2021 Patch: Addressed Stagefright media framework bugs and kernel privilege escalation issues.
• November 2021 Patch: Final significant security update of the year; focused on Android Runtime (ART) improvements.

Important Note: Not all regions received updates simultaneously. ROW (international) devices generally received updates before carrier-specific or retail-demo units. If your tablet is from a provider like Verizon or AT&T (rare for this model), updates may be delayed or absent. Lenovo TBX704F (Tab 4 10) Android Update 2021:

5. How to Check for the Last Official Update

If you are still on an older version and want the last official firmware from 2021:

1. Go to Settings > System > System Update.
2. If no updates appear, you can check your current "Baseband version" and "Build number."
   • The last major build usually ends in something like S000830_200XXX (ROW version).
3. Important Note: Do not rely on "Lenovo Smart Assistant" PC software, as Lenovo discontinued support for it for this tablet model years ago.
