The Elephone Trunk was a budget 4G smartphone from 2015 that stood out by being one of the few Elephone devices to use a Qualcomm processor. It featured a reliable Snapdragon 410 (MSM8916) chipset, a 5.0-inch HD display, 2GB of RAM, and ran on Android 5.1 Lollipop. The use of a Snapdragon chip was a key selling point, often associated with better stability and custom ROM support compared to its MediaTek counterparts. However, like any budget device, it could suffer from performance degradation and software bugs over time. For owners of the Elephone Trunk, reinstalling the official stock firmware is the best way to restore the device to its original, clean state.
Crucial Safety Warning: This firmware is ONLY for the Elephone Trunk. It uses the QFIL flashing tool due to its Qualcomm chipset. Do not attempt to use SP Flash Tool, as it is only for MediaTek devices.
