I try to update my Q24PL001 (legacy modem) firmware with 657h00_full_q24pl001.dwl, of course I upgrade bootloader first. Modem setting setting 115200, 8N1, Hardware.
Bootloader was upgraded succesfully, but firmware upgrade failed (error message like if we click cancel button while hyperterminal downloading firmware to modem).
After that my module not response AT Command at all, led indicator always ON and blink quickly every 15 or 16 seconds, hyperterminal show +WIND: 13 continously after led blink.
From AT_Command_Interface_Guide.pdf i read that +WIND: 13 indicator define as The rack has been detected as Closed.
What can I do to fix this error?
