Hello 👋  
How do I get the android 16 update on my s25 because it keeps on bringing this error when I try:

Couldn't download update

Unable to update the software. A
network or server error occurred. Try
again later.

You have to change the CSC (carrier sequence code) of your device. Note that samsung devices are regional based.

Possibly your phone came with a CSC which is not compartible with your region.

You have to change the csc to one that is compartible with your region. Ask Google the preferred csc for your region.

Once you change you will begin to receive updates.
