A busted BIOS update locked countless ASUS users out of their own drives, and a fresh patch is finally here to clean up the mess.

ASUS AM5 motherboard BitLocker drama
[LIST]
[*]ASUS released Beta BIOS Version 2102 for 600 and 800-series AM5 motherboards.
[*]Beta BIOS 2101 was the culprit, triggering BitLocker on every single boot.
[*]Corruption of Secure Boot logs is what kept the problem alive after downgrading.
[*]Even wiping the TPM didn't get rid of the recovery screen for many users.
[/LIST]
What the new BIOS update actually fixes
[LIST]
[*]Version 2102 ships with an AGESA microcode bump to 1.3.0.0a.
[*]BitLocker got stuck demanding a 48-digit key just to access the drive.
[*]ASUS officially acknowledged the bug before dropping this targeted fix.
[*]Disabling BitLocker pre-flash didn't stop the recovery screen from showing up.

How BitLocker behaves when it gets spooked
[LIST]
[*]Microsoft's full-disk encryption feature is baked right into Windows.
[*]Any detected shift in TPM or Secure Boot settings trips the recovery screen.
[*]A full CMOS clear, reflashing older firmware, and deleting Secure Boot keys all failed.
[*]Hardware-change detection isn't an ASUS-exclusive trigger, but user complaints piled up fast.
