Thank God I've solved my problem! I've downloaded the latest version of mtkflash and I read that it worked best if the drive to be flashed is connected to secondary slave IDE, I did that and it worked like a charm! Still can't understand why the flasher provided by btc doesn't work anymore, now it brings up the blue screen of death showing a kernel stack error or something. But I'm still glad I brought the btc back from the dead!
