error:To flash the bootloader, you have to supply the X-Loader image
 

Hello

I'm trying to get 1.2 firmware to n900.

I successfully installed 1.1 version (RX-51_2009SE_2.2009.51-1.203.2_PR_F5_203_ARM.bin), but then i try to install newer versions I get these errors: "To flash the bootloader, you have to supply the X-Loader image" (placed in image below)
