Do you know if there is a program that can flash the whole firmware?
All of my photos and music is on the hdd, and i don't want to lose them.

You got data on the HDD that you want to save and you are messing with the firmware?
It's time since I last used the hddhackr but I remember taking a firmware backup of every HDD. Did you take a backup before flashing?
Maybe some one with the same HDD model has a backup.
