Looking to install the firmware on the Lenovo A806? This guide walks through flashing the official firmware. The A806 shipped on Android 4.4.2 KitKat and runs on a MediaTek MT6592 processor, so it flashes with SP Flash Tool (the Smartphone Flash Tool).
Rooting, flashing custom ROMs or kernels, and other mods can go wrong and leave a phone bricked, especially if the steps are not followed carefully. If that has happened, this guide shows how to restore or unbrick the Lenovo A806 and get it back to working condition.
Why flash the stock ROM
- Unbrick the Lenovo A806
- Fix a boot loop
- Upgrade or downgrade the phone
- Unroot the phone and clear bugs from earlier mods
- Fix lag and stutter
- Fix other software problems
- Return to stock to restore the warranty (where it still applies)
