MediaTek Helio G81 stock firmware

13 devices in our catalog built on the MediaTek Helio G81 chipset — 55 files in total, every one a free direct download. Because they share the same MediaTek SoC, they all flash the same way: with SP Flash Tool (the MediaTek flashing app). See the stock firmware flashing guide for the full steps.

Grouped from each device's verified chipset. A device is listed only when its chipset was confirmed — not guessed.

Flashing a MediaTek Helio G81 device

Every phone on this page uses the MediaTek MediaTek Helio G81, so the flashing procedure is the same across all of them — only the firmware file differs per model. Download the build for your exact model code, then follow the stock firmware flashing guide. Flashing another model's firmware, even on the same chipset, can brick the device — always match the exact model code.

Also pick the build made for your region. Browse firmware by country or by Android version to narrow it down.
