RE: Latitude 5175 Bitlocker issue after update BIOS 1.0.20 -> 1.0.24
A BIOS flash without suspending the bitlocker would always prompt for recovery as the boot configurations is essentially being rewritten and it is TPM's job to protect your data in such scenarios. By blocking access to the drive and only allowing to proceed as long as the recovery key is provided. Hence the published article suggests to suspend bitlocker. Please refer http://dell.to/2rDTbKJ and Scenario 3 at http://bit.ly/2rjjy5M.
