The Mobicel Rainbow is a budget dual-SIM smartphone from 2016, equipped with the MediaTek MT6580 processor. Originally released with Android 5.1 Lollipop and later receiving an update to 6.0 Marshmallow, its low-end hardware makes it vulnerable to significant software problems. Users often report critical issues such as the phone getting stuck in a bootloop, persistent malware that survives a factory reset, and network connectivity problems with the dual-SIM function. For these advanced issues, a complete reinstallation of the stock firmware is the most effective solution.
This guide provides the official scatter firmware files for the Mobicel Rainbow. The flashing process requires the SP Flash Tool on a Windows PC.

Why Flash This Specific Firmware?
Based on common issues for this MediaTek device, flashing the stock ROM is the definitive solution for these Mobicel Rainbow problems:
- Fix Bootloop and Unbrick Device: If the phone is stuck on the Mobicel logo or is completely dead (hard bricked) from a software error, flashing one of these firmwares is the standard repair procedure.
- Resolve Dual-SIM and Network Errors: Software corruption can lead to issues where one or both SIM cards are not detected, or you experience frequent “No Service” errors. A clean flash restores the correct modem and radio files.
- Remove Stubborn Malware: If your phone is showing pop-up ads or has suspicious apps, a full firmware reinstallation is the only guaranteed way to remove malware that has embedded itself into the system partition.
- Solve System UI and App Crashes: Persistent “Unfortunately, System UI has stopped” errors are a clear sign of a corrupt OS that only a clean flash can properly fix.
- Prepare for FRP Lock Bypass: Flashing the stock ROM is an essential first step if you are locked out by Google’s Factory Reset Protection (FRP), creating a clean system before you attempt a bypass.
