Locked out of a Dell XPS 13 9310 – TPM issue / "PIN not available" & No Recovery Key on Microsoft Account
Hi everyone, I really need some help recovering access to my laptop or finding any potential workaround before resorting to a wipe, as I have critical data on the drive.
Device Details:
* Model: Dell XPS 13 9310 2-in-1
* OS: Windows 11
* Account Type: (surfa)
The Issue:
* My system booted into a Windows login screen showing the error:
("A problem occurred, and your PIN isn't available...").
* Clicking "Configure my PIN" or trying alternative login options asks for a password or redirects to a password reset wizard, but I do not have a set local password for this account—I only ever used a PIN and Fingerprint (Windows Hello).
* The drive is encrypted with BitLocker.
What I've Already Tried:
* BIOS / TPM Checks: I entered the Dell BIOS setup. TPM 2.0 is enabled (TPM State: Enabled, Clear TPM is OFF), and Secure Boot is enabled. I performed a Load Defaults reset in BIOS to re-sync TPM, but Windows Hello still throws the same PIN error.
* Microsoft Account Recovery Key: I logged into my Microsoft Account via web, but the BitLocker Recovery Keys page states (No keys found).
* Recovery Options: Accessing Advanced Options / Command Prompt triggers the BitLocker prompt requiring the 48-digit key.
Questions:
* Is there any known method to restore or repair the TPM/Windows Hello binding for a local account without wiping the drive or needing the 48-digit recovery key?
* Are there any reliable data recovery or chip-level options for retrieving files from a BitLocker-encrypted NVMe drive under these circumstances?
Any guidance would be greatly appreciated. Thanks in advance!
