Did your Vivo iQoo Z1 touchscreen stop responding after flashing the stock firmware? This issue is more common than you think, especially when flashing using SP Flash Tool without the correct DA file or missing firmware components.
Root Cause of Touchscreen Failure After Flash
- Incorrect or generic DA (Download Agent) file used
- Missing or corrupted touch firmware in the scatter ROM
- Incompatible firmware version (wrong build number)
- Incomplete flash due to connection errors or power failure
Solution: Restore Touch Functionality on iQoo Z1
Follow the instructions below to reflash the correct firmware with a verified DA file. This method is tested and resolves touch-related issues caused after flashing.
Required Files and Tools
- Vivo iQoo Z1 Stock Firmware
- Modified SP Flash Tool v5.2044
- MediaTek USB Drivers
Step-by-Step Flashing Instructions
- Extract the firmware ZIP file using WinRAR or 7-Zip.
- Install MTK USB Drivers on your PC and restart your system.
- Launch the SP Flash Tool and load the
MTXXXX_Android_scatter.txtfile from the extracted firmware. - In the Download Agent field, select the custom DA file included in the firmware folder.
- Click “Download” and connect your powered-off phone while pressing both volume buttons.
- Flashing will begin; wait until you see a green check mark confirming success.
Important:
Make sure to choose “Download Only” mode unless you know what you're doing with “Format + Download,” which may erase calibration data, including touchscreen drivers.
Still No Touch Response?
- Try flashing an older or newer version of the stock ROM.
- Use the Format All + Download mode as a last resort (may fix persistent touchscreen bugs).
- Check LCD and touchscreen flex cable connection if issue persists after multiple flashes.
