Ok so I got the original issues fixed but I need to update this XDK to a newer FLASH but upon trying 21256.12 it tells me it's no longer supported and I get this lovely message. Any idea how to get a newer flash? I need to test some beta's and have no other XDK hardware. I've dumped the flash which is 66MB inline with XeDK NAND sizes. EDIT: Ok so remote recovery XDKRecoveryXenon4929.exe is the only one a pre-release hardware system will accept. It came up saying support would be removed in the february 2007 update. Missed taking a pic of the feb 2007 screen but I managed to grab these for those interested. Went from Flash: 4532.0 XDK: 4802.0 to Flash: 4548.0 XDK: 4929.0 doubt it could go any higher without hacking/modding. =============== OriginaI Post Below ============== Spoiler recently obtained an XDK from a shut down game company within the UK, The console is a prerelease Xenon and sadly the sidecar was broken and caused the system to not boot. I removed the Sidecar and the HDD works a charm but it has data on I can't risk losing as it was deleted so I tried to install a new HDD. I can't seem to get this drive to work, I've formatted it within the 360 dash but whenever I try to write files with FATXplorer I get Access Denied yet the original drives fine. So I thought about trying to install FTP but for the life of me I cannot work out how to install FTP. I've got the 360 SDK installed etc and the right files needed. (I think) I should point out I don't normally touch anything newer then the original xbox or PS2 so not great with 360's lol. Pic of the dash below. Any help would be appreciated. It would mean getting better videos and screenshots of an alpha build of crackdown which for some reason is named CarWars. I know the data I recovered works also but trying the files via DVD is being a pain and causes the system to take a lifetime to load. Any help would mean alot I'm useless when it comes to newer stuff.
