Chapter 2. Flash Image

This chapter introduces the detailed steps to flash flatbuild/metabuild/fastboot images with the help of Turbox Easy Flash.

Step 1. Unzip the image package to a definite folder.

Step 2. Click Browse… and navigate to the unzipped file folder as Download Package, and the tool will automatically detect the download type (flatBuild, metabuild, or fastboot). If the image package version is too old, the tool makes intelligent speculations based on the content of the package, and the Download Select dialog box (refer to Figure 2-2) will pop up for users to double check the selection result.

NOTE: You can select “Auto Backup Restore” to backup factory data before download and restore factory data after download automatically. It is often used to avoid factory data lost when downloading, especially you select “Erase All Before Download“, but it will cost more time in downloading process.

Step 3. Select the target device port (e.g., “Qualcomm HS USB QDLoader 9008”) for the Port if the download package type is flatbuild or metabuild, or device serial number for the Port if download package type is fastboot.

Step 4. Click Download button to flash device images.

NOTE: If you failed to flash device with flatbuild or metabuild image or the device cannot boot normally, please make device go into EDL (Emergency Download) mode and retry. Please see FAQ chapter on how to make device go into EDL mode.
