Mobicel R4 LTE Firmware Flash File Download [Stock Rom]

The Mobicel R4 LTE is a budget Android device running on the MediaTek MT6739 platform with Android 8.1.0, LTE/4G, and dual SIM support. User reports and service centers often cite serious faults: bootloops, stuck Mobicel or Android logo, persistent lag, failed update, bad custom ROM, unresponsive touchscreen, or FRP/lock issues. These failures are reliably fixed by flashing the official scatter-format firmware with SP Flash Tool—other tools are incompatible for MTK chipsets.
