Firmware version differences

Now I use xs++ 3.1 . When I trie to connect while pressing C, nothing happens.
I found something about pressing buttons 2 and 5 to connect.
What's the difference?
When I do it with those buttons, it does connect, but I get this log file:

00:15:09| Hold 'C' button on phone and connect phone NOW.

clean your fastport, install SEMC usb driver and try again

Have a nice day

I tried it again on another pc and this time it worked.
Here's the xs++ log:

Use this files:

MAIN: W580_R8BE001_MAIN_GENERIC_LA_RED52
FS: W580_R8BE001_FS_EUROPE_3_RED52 and
CUSTPACK: HB1-06_Gen_CDA102568_12_R8A_GENERIC_EUROPE_3

And do you think this is the easiest way to add a language or is it more easy to add only the language files?
I suppose text messages etc. will be removed when I flash the phone?

Do I need to add the Custpack files one by one using FSX or can I upload it all together?

I still don't have access to the downloads, so I have to wait.

How to get access to Download Area?

Have a nice day

I've requested access some days ago, but didn't get any confirmation yet.
