N00blet in need - try to unlock a k550i on orange

Hi, I've got this k550i on orange and have been trying to follow the tutorials to try and unlock it with SETool2 Lite, when i try to get the GDFS number I keep getting this message -

welcome to setool2 lite,DB2010/DB2012 CID49 edition v 1.01
Loaded 51 flash descriptors
Will backup GDFS now.
ChipID:9900,EMP protocol:0301
PHONE IS RED RETAIL PRODUCT
FLASH CID detected:52
skipping empty loader...
phone pre-boot failed,possible RECOVERY needed.

Is there something wrong and if so is there anyway around this problem so i can unlock my phone. Thank you in advance.
