Look at this tutorial Read Full Firmwares - Top Sony Forums
You find there how to full backup the firmware of your phone.

i know this tut, but its not for cid 49.

i got a second k750 from a friend with exactly the same settings:

ChipID:8040,EMP protocol:0301
PHONE IS RED RETAIL PRODUCT
FLASH CID detected:49
Speed:921600
Flash ID check:200D
Flash props sent ok
OTP LOCKED:1 CID:49 PAF:1 IMEI:xxxxxxxxxxxx CERT:RED
FLASH CID:49 COLOR:RED
 
MAPP CXC article: R1CA021     prgCXC1250035_EU_2_CL
MAPP CXC version: R1CA021
Language Package:VFE_2
CDA article: CDA102338/30
CDA version: R18A
Default article: cxc125953
Default version: R1CA021
 
Network LOCKED

USERCODE:0000 

k750, red, R1CA021, cid49

i tried the .vkp-patch from the "Remove SIM-lock patch generator " also at this phone and guess - it DOESNT work.

on applying i got this message again:

I choose "YES".

Any ideas? I use the included USB-cable.
