Module stopped working

Suddenly wizfi250 module stopped working. It seems like internal firmware problem. After power up it is not responding through uart, sets CTS to low, not responding on FUNCTION pin. Meanwhile bootloader using BOOT pin starts fine, firmware(all) using WIZSmartScript flashing ok, factory recover procedure working. I’ve tried several firmware versions. Still no result.
Any opinions?

Hi

If you saw the BOOT mode (boot pin enables), I think It is firmware independent problem.
Please try factory default using the Function key(push the button 3 times)
Do you have another Evaluation Board of WizFi250? if you have that. Please test the module with another Evaluation Board of WizFi250.
