you can use any little pretty pony you like.

my advice:
download and use the global variant pr1.3.

thats these two files:
DFL61_HARMATTAN_40.2012.13-7.NOMAPS_EMMC_NOMAPS.bin
DFL61_HARMATTAN_40.2012.21-3_PR_LEGACY_001-OEM1-958_ARM.bin


it might fail and say the version youre trying to flash doesnt work. if that happens, then try the variant for your phone.
