The Mobicel Rave is an entry-level smartphone running Android 8.1 Oreo. While designed for basic use, users often encounter software locks and connectivity problems that render the device unusable. The most common issues are being locked out of the device due to a forgotten pattern, PIN, or Google account (FRP lock), and experiencing SIM card not being detected or having no network signal. These problems are typically caused by software corruption or user error. Flashing the official stock firmware is the most effective method to bypass these locks and restore full network functionality.
This guide provides the official stock ROM package for the Mobicel Rave. As a Spreadtrum (UNISOC) device, it must be flashed using the SPD Upgrade Tool.

Why Flash This Specific Firmware?
Flashing this specific MDD_Unlocked_Data_220621 build is the recommended solution for the most common and critical issues faced by Mobicel Rave owners, as discussed on various support forums:
- Bypass Forgotten Pattern, PIN, or Password Lock: If you are completely locked out of your device, this firmware will format the userdata partition, removing the security lock and allowing you to set up the phone again.
- Remove Google FRP (Factory Reset Protection) Lock: After a factory reset, if the original Google account is not provided, the device becomes locked by FRP. This firmware flash clears the authentication, successfully bypassing the FRP lock on Android 8.1.
- Fix “No Service” and SIM Card Detection Issues: A corrupted NVRAM partition can cause the Mobicel Rave to lose its IMEI number, resulting in no network signal. This firmware restore rewrites the NVRAM, reinstating the correct IMEI and modem configuration.
- Resolve a Soft Brick or Bootloop: If the phone is stuck on the Mobicel logo or in a continuous restart cycle due to a failed update or software corruption, this process reinstalls the entire operating system, allowing the device to boot normally.
