I’m using an RV50 with the firmware 4.9.3
While testing a procedure from our Engineering department, I used Putty (serial connection) with the following AT command : AT*USBBYPASS=1
According to the procedure, a new modem was supposed to be installed on my computer, but never happened and now, after a reboot, the RV50 isn’T connecting to the service provider anymore. Also, i can’t connect to the serial interface anymore.
When I boot the RV50, the signal and network LED are always flashing RED and the POWER is a solid green.
I tried to upgrade the firmware to release 18.104.22.168, but I never get the message to upgrade the radio module. After rebooting, I can’t acces the modem using the web interface (192.168.13.31:9191). The only way to get the access back is to boot in recovery mode and downgrade the firmware to 4.9.3
According to the log, there is a problem with the radio module but I can’t find a way to fix it.
P.S Sorry for my bad english/mistake, I hope you all can understand my problem and provide me with some help
