I assume it was flashed but can't yet try to run backup. I don't have the original key So the problem is I don't understand what is the point of all these dashboard updates ? And what is iXtreme? I don't know what was done to the console before me.
Now, the DVD drive inside is DG16D4S Liteon with a MXIC chip. I was able to connect a USB stick to use it as a storage device. However, after reboot it launched anyways and now works on the 6.0 dashboard. So it asked to insert one during the update. I installed it, but the console had no hard drive. Following the code, I learned that it wanted dashboard version 6.0. I acquired an old xbox 360 that had the 'update failed' message.
