Well, I know your feeling incredibly bad right now. How should I know? Because I did the same thing about three months ago. I was playing around with that cursed XBMP and changed the aspect ratio... then bOOm, good bye xbox. Like yourself, I soft modded my xbox with the SC game save modification. Like yourself, I too have a Ver-1.6 or had, I should say, hehe. Here is what went wrong & and a few other tidbits : Trust me on this.
1. The Version 1.6 eeprom was corrupted. As soon as you changed the aspect ratio, your xbox rebooted, only for you too see about half of your screen filled with seemingly multicolored lines ( at the top of the screen )
2. It has nothing to do with the Xbox HD, so forget about it. Save your self the stress and time and totally forget about the stock xbox hard-drive for the moment.
Two options are available to you
A. Purchase a new xbox
B. Mod your xbox with a mod chip.
Here, I'll go into option B in detail
-If you modded your xbox with a mod chip, you'll be able to use a standard ISO9660 CD ROM containing a program called "Enigmah's Video Selector" This nifty little program allows you to change the video settings stored within' the EEPROM ( which is the root of your problem )to either PAL or NTSC, by the press of a button.
-exception " Why can't I do this now? " or " Is there anyway to do this without hard modding my box? "
-Your booting process consist's of this
Xbox logo and animation ( flubber )Cool, all is well with that.
Directly following the animation, your greeted with the odd looking lines at the
top of the screen. PROBLEM.
Well, you see, That's why a "hard" modded xbox is required in this instance. The said method of repairing your xbox requires that you have a "hard" modded xbox, so that your mod chip will recognize the ISO9660 CD-ROM and boot it, thus giving you a chance to REPAIR YOUR EEPROM BACK TO YOUR ORIGINAL STATE. All you have to do is press a button ( A for ntsc or B for Pal, I may be wrong in regards to which button does what, but you can find that information in the readme or .nfo )
I posted some screen shots on the boards here a few months ago regarding this topic. In these screen shots, one could see exactly what you've described here. Also, about a nice 5th of the post's in that thread suggested that my xbox suffered from EEPROM curruption.
My fate is as bad as yours, my friend. However, I think mines is worse, for I was planning a mmorpg project for the xbox and my last dime went toward purchasing that damned piece of equipment.
closing remarks:
I'm glad to see you backed up your data, though. Very smart move. This was something I did not do, but wish I had. For if I did, I could be using and or have access to the contents of my hard drive ( *cries* Halo and the entire street fighter series, damn )
If you have any questions regarding your problem or if I stated something that was not so clear, please PM, I'd be more than willing to help you.
Also, a quick edit here:
FTP'ing to your xbox's hard-drive to execute Enigmah's manually.
Various people on boards has had this method work for them, however, this is only possible if you hard-modded your xbox.
