Introduction
The Unblock Tech Gen 2 TV Box was once a popular device for streaming movies, dramas, and live TV channels. Out of the box, it came with Android 4.4.2, which at the time was reliable and smooth. However, as technology moved forward, users began asking the same question: Is it possible to upgrade Unblock Tech Gen 2 Android 4.4.2 to 5.1.1?
This guide provides a clear explanation of the upgrade process, the challenges, and realistic alternatives if an official upgrade isn’t possible. You will also learn how to restore your device, optimize its performance, and make the most of it in today’s environment.
Understanding Your Device
Before discussing upgrades, it is important to understand what you actually own. The Unblock Tech Gen 2 (UBOX Gen II) is an older model that came with limited hardware specifications. Typically, it features:
- Processor: Allwinner H3 or similar ARM Cortex chipset
- RAM: 1 GB
- Storage: 8 GB or 16 GB
- OS: Android 4.4.2
Knowing your hardware is key because it determines whether upgrading from Android 4.4.2 to 5.1.1 is even possible.
Assessing Upgrade Feasibility
Here is the honest truth: there is no official Android 5.1.1 upgrade for Unblock Tech Gen 2. The company stopped supporting this model, and the hardware limitations make it difficult to run newer Android versions smoothly.
The main reasons include:
- Hardware Constraints: With only 1 GB of RAM, running Android 5.1.1 would be unstable.
- Driver Compatibility: Updated firmware requires hardware drivers that Gen 2 doesn’t support.
- Lack of Vendor Support: Unblock Tech has focused on newer generations like Gen 4, Gen 8, and Gen 9, leaving Gen 2 without updates.
Common Upgrade Attempts and Pitfalls
Many users have tried to force an upgrade from Unblock Tech Gen 2 Android 4.4.2 to 5.1.1 by using firmware from newer models. Unfortunately, this often leads to serious issues:
- Soft Brick: The box gets stuck on the logo and won’t boot.
- Hard Brick: The device doesn’t power on at all.
- App Instability: Even if forced upgrades succeed, apps crash frequently.
This is why it is strongly advised to stick to Gen 2 compatible firmware only.
When Re-Flashing Android 4.4.2 Makes Sense
If your device is freezing, showing errors, or refusing to boot, the best solution is not to upgrade but to re-flash Android 4.4.2. This restores the box to its factory condition and makes it usable again.
Re-flashing is also helpful when:
- Your UBOX is stuck on the boot screen.
- Apps keep crashing.
- You accidentally installed corrupt firmware.
Step-by-Step Guide: Restoring Android 4.4.2
Here’s how you can safely restore your Unblock Tech Gen 2 Android 4.4.2 system:
What You Need
- A microSD card (4–16 GB, formatted FAT32).
- A PC with card reader.
- The official Gen 2 firmware file.
The Process
- Download the correct Gen 2 firmware (do not use Gen 3 or Gen 4 firmware).
- Extract the zip file and place the contents in the root directory of your SD card.
- Power off your device and insert the SD card.
- Locate the reset button (usually inside the AV port, press with a toothpick).
- While holding reset, connect the power cable.
- Release after 10–15 seconds when the update screen appears.
- Wait 3–5 minutes for flashing to complete. The device will reboot automatically.
This will bring your Unblock Tech Gen 2 back to life on Android 4.4.2.
Risks and Safety Measures
Re-flashing or upgrading always carries some risk. Here’s what to watch out for:
- Using the wrong firmware may brick the device permanently.
- Interrupting the process may leave the box unusable.
- Power failures during flashing can corrupt the installation.
Safety Tips:
- Always double-check the firmware version before flashing.
- Keep the device connected to stable power.
- Use only trusted sources for firmware downloads.
Alternatives if Android 5.1.1 Is Not Possible
Since upgrading Unblock Tech Gen 2 Android 4.4.2 to 5.1.1 is not officially supported, here are your best alternatives:
Option 1: Keep Using Android 4.4.2
- Install older APK versions of apps like YouTube, Kodi, or Netflix.
- Use lighter apps that require less memory.
- Stream via browser if certain apps don’t work.
Option 2: Upgrade to a Newer Unblock Tech Model
Unblock Tech now offers models like Gen 9 Pro that run Android 10 or higher, supporting modern apps and smoother performance.

Conclusion
