In this blog post, you’ll find the download link to Nusantara Project Android 11 ROM for Tecno Pouvoir 3 Plus LB8A, how to install the ROM on your Tecno Pouvoir 3 Plus LB8A device and how to root the ROM.
The Tecno Pouvoir 3 Plus comes with a 6.35-inch waterdrop notch AMOLED display with 64GB/4GB memory and runs the HiOS based Android 9 OS out of the box. While the device will continue to receive security updates for a year or two, it will not be getting an OS upgrade.
Although Tecno devices are great, not having OS upgrades is why many of the Tecno and Infinix fans have moved to brands like Xiaomi, Oppo, Samsung etc. I’d say the company really care for its fans. Tecno doesn’t push its latest HiOS skin to older devices, this would have been great since the company fails to provide OS upgrade, instead, it focuses on producing new devices and add it latest HiOS skin and features to it.
Tecno users, however, are not completely left in the dust, you can still upgrade your device to the latest Android OS and add several features with the help of custom ROMs. Thanks to Google’s project treble, all Android 8 devices and newer can install new the latest Android OS version even if the manufacturer is not providing it.
