It seems you've encountered a similar situation with your ThinkPad T450 Stin20B running an i7-5600U CPU, 16GB RAM, and Windows 10. You're considering upgrading to Windows 11, but this model is not officially supported for that version.

You attempted to install Windows 11 using the Bypass Method, which led to a rollback due to registry issues. The recommended approach was to use Rufus with a patched installer, disabling TPM, Secure Boot, and CPU checks, and ensuring no MS account login is required. However, even after following these steps, the installation failed during the SAFE_OS phase with error code 0x8007000D – 0X20009. You also tried a clean install and a flyby installation without success.

If you're looking for advice on how to proceed, consider reaching out to Microsoft support or checking community forums for similar experiences.

On ThinkPads such as the T450, the rollback isn’t due to TPM or CPU issues; it’s typically a driver-related problem during SAFE_OS. When using FlyOOBE, ensure you’re employing the upgrade tool within the FlyUp.exe folder (not FlyOOBE.exe). FlyUp manages all bypasses and prevents driver conflicts that lead to PREPARE_ROLLBACK errors on older ThinkPads. Simply run FlyUp, let it download or apply your ISO, and proceed with the upgrade—this method has worked for T450, T440, and X250 users.
