Hi Jooolr,
First, I'd test the battery voltage; it should be at least 12.5 volts (minimum 12.3 volts under load).
Secondly, you need to check the battery terminal connections, making sure the bolts are tightened correctly (poor tightening will cause the BMS relay to trip, blocking the starting current).
I don't know what procedure you used to replace the battery. If you also disconnected the fuse box wiring, make sure it's also tightened properly.
Third, if that doesn't work, try resetting the BMS again.

everything is connected probably. I don’t think the problem is regarding the 12v battery. It’s brand new and the voltage is accurate
I think your issue may be the 48 v battery. You cannot charge this 48 v battery. The vehicle has an internal 12V-to-48V boosting function meant to recover a low hybrid battery, but it requires the Land Rover Pathfinder diagnostic software to force-initiate the "MHEV Battery Wake-up" or "Energy Force Charge" procedure. I recommend you take it to a specialized Land Rover tech or your Land Rover dealership.

I called the dealership already. They need the car to be towed and I won’t do that! I will take just the battery somewhere to be charged but really don’t know where should I go! Do you know somewhere can charge the 48v battery? I am in Orange County, California
