Hi,
I've tried to flash my K750i with W800 firmware at first, but it wouldn't boot, so I'm trying to put K750i back on. When I power up the fone, I get:

Configuration error. Please contact your network operator or service centre.
I'm using the following 2 files:

K750_R1CA021_MAIN_EU_1_CL_RED49.mbn

K750_R1CA021_FS_EMEA_4_RED49.fbn

Are these correct? Here's what SETool2 Lite said when I clicked 'identify' before I cocked it up (when it was working fine)

By the way, I'd still like to get the W800 firmware working if possible. I'd like to know the exact files to use.

Please try to explain in laymans terms, I'm new to phone flashing :)
