ok so for starters, im using the ck3 po rev d and my desktop computer.

so basically i accidentally erased my firmware off my drive. using the ck3 pro i managed to get the drive into vendor mode. i load my dummy.bin as the source(making sure i say no to auto load), and the ofw.bin as the target.then i click spoof to target. i click lite-on erase, then write. i get an error saying unknown flash type. any ideas what im doing wrong? will post jungle flasher log also.

incase this matters, i have to send my drive into vendor mode before i click lite-on erase because if i try to power cycle into vendor mode, it freezes my pc
