Hello, I just upgraded my module to RM500QAEAAR13A03M4G_01.201.01.201 and I’m from version RM500QAEAAR11A03M4G_01.200.01.200, and after upgrading the disconnection bug worsen, and I want to get back to RM500QAEAAR11A03M4G_01.200.01.200, then I downgraded my module to it, and now I can’t use the module (the router can’t connect to the module it’s logs says "Get profile Modem 1 is can’t open device /dev/ttyUS Can’t open device /dev/ttyUS)

Can someone help me, my RM500Q-AE still responds to module upgrades pls help em

From Release Notes:

The new firmware version cannot be downgraded to previous versions, otherwise the module
will not be able to work normally.

I suggest to re-flash the latest then test the modem with PC, not a router.
