Regarding currupt security patch of july2020

[Ashudprfct]

Once after update of july security patch my Samsung Galaxy Note 8 became a wifi only brick

No support to mobile networks 

Not able to login Samsung accaunt 

No IMEI number is displaying 

Now the question is will they fix this problem 

If they will, how..?

Because the device is not registered anymore

And software update section is not functional 

I was really thinking to stick with this brand in future but after this, I completely lost my trust with samsung
