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>
