XBee Pro SX fail to work.

Recently I found a problem when testing XBee pro SX. Please help check if it can be solved.
Questions are as follows,
The original firmware version of XBee pro SX is v9004. It can work normally after modifying the firmware in two ways (1. Write XTC Hoping v2004; 2. Upgrade to XBee pro SX v9007) without any problem. However, if XBee pro SX v9007 firmware is written directly from XTC Hoping v2004, the XBee module will not be able to read and write data through X-CTU. Is there a solution to restore factory settings ? Otherwise, xbeepro sx will become a brick and cannot be used. Thank you
