Openwrt for Ha5420 modem

The problem of locking the SIM card of the ha5420 modem

 I have a ha5420 SIM card modem. I mistakenly activated the SIM lock feature in the modem's network settings. It does not recognize the SIM card at all and has no antenna! Even after disabling that feature and factory reset!

 Did any of your friends send the firmware for this modem? Or does anyone know how to solve this story?!
