Has anyone experienced the (Internal error: 1) after using the beta image on the MR600 router? If yes, what is the fix for it?

Hi Team, I have an MR600 router (V3 model). I'm facing the exact same issue — no internet access when using a Jio SIM card that previously worked in a 5G phone and is now being used in the MR600...

Could you please fix this. I purchased a new one v3 Mr600 router and career agreegation not working here. It's waste of money. I tried jio 3+5 not working. Jio 3+40 not working 40+40 sometime coming...
