A flash file, or stock firmware, is the official operating system (OS) created by the manufacturer. For the Kechaoda K115, this is typically the Symbian v9.1 OS. Flashing reinstalls this software, essentially restoring your device to its factory state. The main Kechaoda K115 stock firmware file is often identified by a filename like Kechaoda_K115_MT6261_051218_MIRA.zip .
The phone gets stuck on the Kechaoda logo during startup.
