Hello everyone!I am new in this forum and please forgive me if I make a mistake.I decided to hack my Arcade xbox 360's dvd drive-LiteOn DG-16G2S using this guide : http://www.game-tuts.com/community/f36/tut-flashs-liteon-without-ck3-93029/ because I havent had CK3 and CK3-probe and the tool for powering the drive.My PC's sata is onboard nvidia nforce.Everything went OK.Xbox readed the dvd drive.I burnt 2 discs just in case...Xbox showed Play ...(game's name) when I put the discs.But when I press Play it goes black screen and says Disc is unreadable or disc is Unsupported.I thought that it's because my discs werent burnt properly.I tried them on my friend's hacked xbox and they worked both.I decided to change my DVD drive's firmware using xbox as power source(used it before as power source) and it stuck on erasing.Then I tried to stop and start the dvd many times and now my xbox's J1D1 port isnt working but the dvd is flashed after many trys and its working fine(tested it on other xbox).On my Xbox,start button's led is always flashing green and it powers up the drive but sends wrong commands to it(like when i press the dvd button it shows opening in dashboard but its closed and laser blinks and after that tray opens again and dashboard is showing always Opening) and led is always blinking when DVD is attached and when it isnt.ANd as result everything works but J1D1 port dont.Can i fix it without soldering?Or how can i fix it at all?
