1. Keep both copies of eeprom.bin safe on your PC.
2. I'll label working softmod xbox "S" and non-working xbox with the hdd unlocked "T" for ease of identification.
3. If you have another brand of dvd drive on T other than Thomson, you could swap that over to S. Remember to set hdd jumper of T's hdd (target to be locked) to slave as well. See if that dvd drive has any luck booting LUD successfully.
If step 3 still fails, the last option I can think of is to edit the hdd key of S to match that of T. Ref this thread:
http://forums.xbox-s...howtopic=683310. We'll use a variant of this method but instead of zeroizing, we will edit the hdd key to match T's key. Copy down on paper or print out the hdd key displayed for T's eeprom.bin as shown in LiveInfo on your PC. Next do this:
QUOTE
1. For softmods, disable virtual eeprom.
2. In ConfigMagic, press Start button and select unlock hdd.
3. Edit on the fly eeprom in ConfigMagic.
4. Edit hdd key to match T's key
5. Select Update xbox eeprom option.
6. Load eeprom option in ConfigMagic.
7. Lock hdd option in ConfigMagic
If you are uncertain over any of the steps, report back here. If you are unsure how to disable virtual eeprom, you'll need Frosty's rescue disc. We will prepare a special edition of Frosty's disc using a variant of this thread:
http://forums.xbox-s...howtopic=6544671. Get UnleashX from the usual place. You won't need Kingroach's.
2. Extract Frosty's iso to a folder. I name it lxhdm.
3. Delete root.xbe from lxhdm folder.
4. Copy unleashX.xbe to the folder and rename as root.xbe
5. Delete away DVD2xbox folder in Applications.
6. Create a ConfigMagic folder in Applications and copy the relevant files there.
7. Create the xiso with qwix.
8. Burn to a DVD-R at 2x. (or whatever media works for your xbox's dvd drive - TDK).
If any of the steps are unclear, report back here.
Cold-booting with this disc will disable virtual eeprom. The final procedure is to perform error 5 hotswapping with lxhdm disc to lock T's hdd using S to boot lxhdm disc. Prior to this, S's eeprom hdd key should already match T's key. Error 5 hotswapping steps:
QUOTE
1. Eject dvd tray and insert lxhdm dvd. Power off.
2. Connect hdd IDE cable to T's hdd in S's. Supply power to T's hdd.
3. Power on xbox. You will get an error 5 which is expected.
4. Unplug hdd IDE cable but keep external power to T's hdd (in S's)
5. power off xbox and connect hdd IDE cable back to S's hdd.
6. power on and lxhdm dvd will load.
7. when unleashX is loaded, unplug hdd IDE cable from S's hdd and plug it to T's hdd.
8. Use UnleashX file manager , navigate to D drive and launch default.xbe.
9. When UnleashX is relaunched, use file manager again and navigate to ConfigMagic on D:\Applications\ConfigMagic\default.xbe and launch that.
10. Verify hdd details match those of T's in ConfigMagic.
11. Lock T's hdd in S with ConfigMagic.
