Click on the lightning bolt icon in the top left corner. Select "Flashmode" from the pop-up window. Choose the firmware version from the list. On the right-hand side, under the "Wipe" section, check "USERDATA" and "CACHE" if you want a clean install. Step 3: Connection flashtool-v5.0.1

FlashTool v5.0.1 is a robust, professional-grade flashing utility suitable for embedded system developers, repair technicians, and advanced hobbyists. Its v5.0.1 release corrects major stability bugs from the initial v5 release while adding modern flash storage support. The move to CLI-only may inconvenience casual users but improves automation. Users requiring GUI should stay with v4.x or use third-party wrappers.
