Can not decrypt bitlocker with PIN

[minhphungbk03]

Dear Romain Coltel & ALL,

I face with the issue as following about dislocker. I would appreciate if someone could help:

ENCRYPT STEPS:

• Install windows 10, version: 21H1 (OS Build 19043.1052) on HP ProBook 650G1
• Disable TPM
• Encrypt that disk with PIN: 159456 . Option: used space (not entire disk).

DECRYPT STEPS:

• Boot above laptop with ubuntu boot usb
• Decrypt with command: "dislocker -r -V /dev/sda3 -u159456 -- -o nonempty /media/bitlocker_Disk3" The output is:

  Fri Jul  9 09:04:48 2021 [CRITICAL] None of the provided decryption mean is decrypting the keys. Abort.
  Fri Jul  9 09:04:48 2021 [CRITICAL] Unable to grab VMK or FVEK. Abort.
  free(): double free detected in tcache 2
  Aborted (core dumped)

• dislocker's version: v0.7.1 (compiled for Linux/x86_64)

P/S: It is possible to decrypt using recovery key. Thank for your time & your support! /PhungCM

I have the same problem with a dell xps 17. Windows 11 uses fingerprint auth (with "PIN" fallback). I was never was asked a password during windows setup.

Decription fails with same message as OP when I try to open the device. I have tried entering the pin as the password, to no avail.

I recently had this issue and came across your post in my search for the answer. I wasn't able to find a link to a solution so I decided to post the solution that worked for me.

My problem was that I was appending the bitlocker password with the decrypt command like you did above: dislocker -r -V /dev/sda3 -u159456 -- -o nonempty /media/bitlocker_Disk3

My solution was to remove the password and run the code without it. You'll be prompted to enter your bitlocker password after running the command. (I also used an alternate version of your code): dislocker -r -V /dev/sda3 -u -- /media/bitlocker_Disk3

I hope this helps!!
