not to put a bucket of water on peoples hopes..but two of my friends got E 71 errors (one has ms25 and the other ms 28) and theyre both cryinf coz they dont know how to fix this.. are you saying there is a solution .. if so could you tell me
thanks
There is a solution, you just reflash the drive using XBOXSAM 0.5, like the guy above you posted. The reason this happens now is that MS has integrated some new features into the kernel, these are DVDVERSION check and DVDMODEL check (correct if im wrong there). The 360 checks these against your ORIGINAL stock firmware and if your hacked firmware is a lower version or the drive is a different model then you get an error. Its fine if the hacked firmware is a higher version because MS allow for ugrades to firmware, just not downgrades now.
So if you have an MS28 and youve flashed with xtreme 3.3 then youll have problems because the version will be lower than your original drive firmware (as 3.3 was based on ms25).
So either reflash with a higher firmware or reflash using the XBOXSAM 0.5 method (which copies the dvd version and model sections from original firmware now i think... correct me if im wrong though).
Have your friends tried to reflash the drives? if so what firmware do they have on there atm (hacked/ unhacked, version etc...)? if you post more details about what they used and are trying to do then you can get more help from people on here.
