Download Hello K80 Stock Firmware (Official .pac File)

The Hello K80 is an ultra-budget smartphone from 2020 powered by a Spreadtrum SP7731CEB processor. It runs on Android 6.0 Marshmallow and, like most devices in its class, features extremely limited hardware, likely 1GB of RAM and a small amount of internal storage. A critical distinction for this phone is its Spreadtrum chipset, which requires a different flashing tool and firmware type compared to MediaTek devices. For owners of this phone, performing a clean firmware flash is the only effective way to combat severe performance degradation and restore the device to a usable state.

Crucial Safety Warning: This firmware is for a Spreadtrum (SPD) device. It is a .pac file and must be flashed using the SPD Upgrade Tool or Research Download Tool. Do NOT attempt to use SP Flash Tool, as it is incompatible and will brick your device.

Hello K80 Firmware Details

Below are the key specifications for the Hello K80. Note the Spreadtrum chipset and the corresponding .pac file type, which require a specific flashing procedure.

Why Flash the Stock Firmware on Your Hello K80?

Due to its very limited hardware, flashing the stock firmware is essential for addressing the critical performance issues that make this device nearly unusable over time:

• Fix Extreme Performance Lag: This is the primary reason to flash. A clean OS install is the only way to handle the severe system-wide lag that makes even basic navigation a slow and frustrating experience.
• Resolve “Insufficient Storage” Errors: Wipes the device clean, freeing up the very limited internal storage to allow essential system functions and a few apps to run correctly.
• Stop Constant App Crashes: Solves persistent “force close” errors caused by the device running out of its minimal RAM when trying to run modern applications.
• Remove Viruses and Malware: Older, unpatched devices are highly vulnerable. A full firmware flash is the only way to guarantee the complete removal of any malware.
• Fix Bootloop Errors: The definitive solution for a phone that is stuck on the Hello startup logo and will not boot.
• Unbrick Your Device: Can revive a phone that has become completely unresponsive due to a software error.

⚠️ Important Prerequisites
