⚠️ Warning for 5Star Z-22 Users
Important: This device was released under different board configurations, and not every “Z-22” ROM fits all units. Flashing the wrong preloader or using the wrong chipset ROM may permanently brick your device or cause it to fail detection on PC. Always confirm your hardware platform first — MediaTek (MT6572) or Spreadtrum (SPD). If unsure, open the phone’s back cover and check the printed motherboard label before proceeding.

How to Flash the Firmware
Five Quick Steps to Flash the Stock ROM
- Identify the chipset: Confirm if your device is MediaTek MT6572 or Spreadtrum SPD. This determines which tool and drivers you’ll use.
- Extract the firmware: Unzip the downloaded ROM on your PC. MediaTek firmware should include a scatter file (
MT6572_Android_scatter.txt), while SPD firmware contains a.pacfile. - Install drivers: – For MediaTek: Install VCOM USB Drivers.
– For Spreadtrum: Install SPD/Unisoc Drivers. - Load the flashing tool: – MediaTek users → use SP Flash Tool and load the scatter file.
– Spreadtrum users → use SPD Upgrade Tool (ResearchDownload) and load the .pac file. - Start flashing: Power off the phone, connect via USB, and start the flashing process. Wait for the success message before disconnecting the device.
