I had change of heart, the guys over at 360mods prevailed on me to release this for free.
So for all to see , here is how you fix the update failed error in all cases:
The error seems to happen when the 360 is unable to read from the update source during the update. The only time I have actually seen it occur was when updating from a backup, which is a common cause Ive read about. The other common cause is an onset of RROD during the update. Im not sure what causes the hard drive error. Either way, the solution is simply to supply the 360 with the correct update file either on a CD or a USB stick. Now here's the rub, it has to be the exact same update file as the one that failed. Not a problem since I've made a nice torrent file with all of the updates to date here:
GoogleThe version number is shown at the bottom of the error screen. PV is for previous version and CV for current version. Just put the file matching the current version (the one you are updating to) on a USB stick, (i.e. E:/$SystemUpdate) put it in your 360, and power up. If you have the right one it will finish updating and boot to the dashboard. Voila.
This has worked for me on 7 consoles so far. 3 of them said they couldn't detect the hard drive and the other four the update disc, so this seems to work in all cases. I hope this can help some people out.
Found this forum last night and wanted to share my experiences with the community. First off I tracked down the update package on TPB (The pirate bay) under the account of "soulslinger" -Just search for the package, or search for the user and you should find it. (Im not going to post the link as im not sure about the forum rules here regarding links to torrents)
Second, I discovered a few "quirks" in making this work correctly. My first attempt was done using a portable hard drive and I realized after about 7 attempts the console will not read the update off a portable (at least my portable anyways) so I did some checking on the MS site and discovered you have to use a usb flash drive and it has to be formatted to FAT32.
Furthermore I realized (again after several attempts) that you need to copy not only the files inside the $systemupdate folder, but the folder itself.
After I got everything just the way the xbox liked it I started trying updates and voila!! After 4 attempts the machine posted to "would you like to update your console" instead of the Purple screen.
-So, it does work and big thanks to SoulSlinger for putting the package together and posting the info.
Just to recap, heres the instructions in point form:
1. Download update package (torrent) from TPB under user account "SoulSlinger"
2. Unpack said package, you'll see several folders starting with 2.0.xxxx.xx
3. Format your USB stick to FAT32
4. One by one open up the 2.0.xxxx.xx folders and copy the $systemupdate folder and its contents onto your usb drive.
5. Plug your USB into the back of the xbox and power the machine up. If you get the wrong update it goes to the purple screen. Plug your USB back into your computer and try the next update.
6. Once you get the correct one, it will (in my case) as you to update. Say yes.
7. Play COD5
