4. Rescue XBlast

In the unlikely event that the XBlast Lite does not power ON due to an interrupted OS update or general flash corruption, there is a failsafe mechanism in place that will allow you to rescue your XBlast. On the XBlast Lite modchip, there is an unpopulated port with "SW1" and "SW2" labels next to it.

This port enables you to manually select a flash bank to boot from, bypassing XBlast OS initial boot up (Even if you enable Quick boot feature, XBlast OS still boots for a very short time, selects the appropriate user flash bank and boots it. You just don't see it). So if you have a user flash bank containing a valid Xbox BIOS, you can boot from that BIOS and then launch the XBE version of XBlast OS to reflash your OS on the XBlast Lite. Linking SW1 pin to ground (center pin of the port) will boots 512KB flash bank. Linking SW2 pin to ground (center pin of the port) will boots 256KB flash bank.

Here is the procedure to rescue your XBlast Lite:

1- Partially disassemble your Xbox. Exposing the motherboard and the XBlast Lite modchip.

2- Remove XBlast Lite modchip. Don't forget to unsolder all the wires soldered to it (D0, L1, etc...)

3- Solder a piece of jumper wire between SW1 and center pin (ground) of the port to enable booting from 512KB flash bank or SW2 to center pin to enable booting from 256KB flash bank. Soldering both SW1 and SW2 will do the same thing as soldering only SW1.

4- Insert back the XBlast Lite on the LPC port of the Xbox motherboard. Solder back all the wires your previously unsoldered from it(D0, L1, etc...).

5- Partially reassemble your Xbox. At least your Hard Disk Drive must be connected to boot to your Dashboard.

6- Launch XBlast OS.xbe from your dashboard. It can be on your Hard Disk Drive or burned DVD-R/CD-RW.

7- Follow the procedure to update XBlast OS as described in the manual.

8- Once the update procedure is successful, unplug your Xbox.

9- Remove the jumper on the Rescue port. Remove the XBlast Lite from the LPC port if necessary. Neither SW1 or SW2 must be connected to ground (center pin of the port).

10- Reassemble your Xbox.

11- Boot your console and XBlast OS should load correctly.

If the above procedure is not working for you, please seek help on the Internet. You can try to contact "bennydiamond" and/or "pysko_chewbacca" on various Xbox-oriented forums or on https://xblastmod.wordpress.com/
