After following the procedure to flash the GNSS_RTK_SDK firmware, both Yellow and Green LEDs do not flash. Right now I cannot get back to the original one with both Yellow and Green LEDs flash after the power is on (Red LED near the USB port is on).
In my first report shown at the top, I have already reported "The 2nd iusse: I tried to upgrade the module RTK_INS firmware Ver.1.2.2. It did say "Upgrade operation is finished. your device is updated". However, after restarting the device, the firmware version is still Ver.0.1.1 (see Figure 1.4(b) in the attached PDF). What did I miss for this issue?".
