Yes, that worked fine for him already, I think. The only piece missing is the device specific information. And I don't see why anyone should light-heartedly present their own data for this - agreedly - noble cause.

term1nat0r: What you would need to do now is:
- dump the part of the flash that holds the device specific information
- restore sensible values with a hex editor
- write the changed data back to flash.

You need to dump 0x400 Bytes (1kByte), starting at position 0x00040c00.

The first 16 bytes are the serial number (ASCII encoded), 12 Bytes starting at offset 88 (decimal) represent the MAC address (ASCII-encoded again, here it's the Wifi-MAC, I don't have a 3G unit to test).

Note that serial number and MAC are stored in a special section of the Flash which is _not_ part of any partition. No need to dump the whole device, though. See the exact offset/length I cited above in this post.
