Contacts and Phone have disappeared - Galaxy S7

It didn't move on from that stage, I aborted it. Risky I know but phone still ok.
I'll kick it off again.
 
My S10 says it is BTU. It is unlocked. Could he need to use the BTU code instead? Just asking. Even when I had my giffgaff sim in the phone it said the firmware was BTU.
 
Worth a go I guess?

Thanks

Just trying to download BTU but may have exceeded the number of DL's I can have in 1 day for a free account :(
Use the samfirm tool for firmware i showed in my guide earlier , download and extract
Put model number
Region BTU
 
Tried with BTU file but same thing :(

Will leave it running overnight but don't think it will progress.
 
Also we need to know before you abort what error message odin will say , disable any firewall on computer also so it doesn't interfere

As expected leaving overnight didn't progress but tried this morning with Odin 3.14.4 and the BTU image and it worked! :)
