How To Install Stock ROM on ECHO Java (Firmware/Unbrick/Unroot)

The ECHO Java is powered by a Spreadtrum CPU. The firmware is for SC7731 versions. The firmware size is around 721 MB so we recommend having stable wifi while downloading the firmware. This ROM can be flashed using SPD Flash Tool. The Official stock firmware file name is Echo_Java_SC7731_20170427_6.0_SPD.zip. The Firmware is based on Google’s Android 6.0 Marshmallow OS.

There are two types of Firmware in the Android Ecosystem. 1) Stock Firmware 2) Custom Firmware/ ROM. Stock ROM is the firmware which comes pre-installed on the device and that is specially developed for the device hence provides better stability and performance. But as stock firmware has very limited features users usually root and install third-party ROMs to get new features and performance boost. But sometimes in that process, users brick their devices.

There are many reasons why a user wants to install the stock firmware. The main reason is to fix a bricked device. Sometimes users brick their devices in the process of rooting and the only way to fix that is flashing back the stock firmware. The other reason is to fix a sluggish or laggy device. With time android devices slow down and by flashing the stock firmware can fix the problem.
