Describe what LB actually does now The Capacity Unlock page still described raising the partition lengths in memory, which was removed after hardware showed it cannot reach the goal - the console formats to the signed sector count regardless - and destroys data while it lasts. Rewritten around removing the flash signature, with the measurements behind it: the extra space on a flashed drive is real (no HPA, writes at 150 GiB read back), the signature offset is a load-immediate so it is identical on every drive, and clearing the content volume header alongside is what stops the console reaching E71.

Document original Xbox compatibility, the capacity unlock and the two builds Compatibility is the headline: SystemPartition turns out to be the backward compatibility partition, so mounting it on an unsigned drive is all that was ever needed to run original Xbox games. Confirmed on hardware. Corrects two things this wiki got wrong. The capacity/avatars trade-off is gone - LB reaches the hidden capacity of a flashed drive without writing to it. And the claim that avatars are simply unreachable now carries the case where they do work: a console with 4 GB of internal flash, with the update installed there. The on-console format page stays as a pointer, since the formatter is debug only now. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Correct the avatar and capacity claims, and document the three format modes The power-on explanation for avatars was wrong: the updater rescans when a device appears, shown by the update menu coming up on USB insertion from inside the dashboard. The actual cause is the disk key slot 0x1001, which is write-once per boot - replaying a valid sector returns 0xC8000002 even on the drive that had just authenticated with it. The capacity-versus-avatars trade-off is also gone for a flashed drive: LT+RT+LB keeps the signature and marks the content partition, and system content lives in SystemExtPartition, which the resize never touches. Verified at 218 GiB with avatars working. On-Console Format now documents all three modes rather than LT alone, and the partition list matches what the code writes.
