Lenovo Rma Shim Download __TOP_

A problem for regular (single-board) RMA shims is that we have to create separate per-board RMA shims for each project, which makes it hard to manage shim images and physical USB drives. A universal shim contains multiple RMA shims for different boards, which is easier to manage and distribute.

The RMA shim has a menu that allows the user to select an action to perform, which is described in Factory Installer README. Moreover, if the RMA shim is created using image_tool rma create command, the tool adds a flag RMA_AUTORUN=1 in lsb-factory file, which sets the default action of the menu depending on the cr50 version and hardware write protection status, such that:

During installation, you can remove the RMA shim when the copy is complete (the text color changes from yellow to green). After the installation, the device will boot into the test image with factory toolkit. Run through the factory tests to complete the flow. The last test should wipe out the factory test image and enable the release image.

image_tool rma merge supports merging universal shims. If there are duplicate boards, it will ask the user to select which one to use. It can be used to update a board in a universal shim using an updated single-board RMA shim.

What shim is used to boot - shim from Leap or shim from Tumbleweed? Did shim from Leap boot at least once after update? Did shim from Tumbleweed boot at least once after update? Which shim fails - Leap or Tumbleweed?

My Acer ES1-512 has been running with opensuse 15.4 for months. With the update of 31.03.2023 comes only the message:

"Verifiying shim SBAT data failed: Sectity Policy Violation

Something has gone seriously wrong: SBAT self-check failed: Security Policy Violation "

The Leap 15.4 install iso cannot boot. A Tumbleweed install iso cannot boot. Leap 15.3 cannot boot, unless I use the new shim from Leap 15.4. And Tumbleweed cannot boot unless I use the new shim from Leap 15.4.

Absolutely correct as I explained in bugzilla. Except you need shim that supports and actually performs SBAT validation, not sure when it was added. As I explained in bug report you can reset minimal required shim version (but booting Leap 15.4 shim will set it again).

Using a signed boot loader means using a boot loader signed with Microsoft's key. There are two known signed boot loaders: PreLoader and shim. Their purpose is to chainload other EFI binaries (usually boot loaders). Since Microsoft would never sign a boot loader that automatically launches any unsigned binary, PreLoader and shim use an allowlist called Machine Owner Key list, abbreviated MokList. If the SHA256 hash of the binary (Preloader and shim) or key the binary is signed with (shim) is in the MokList they execute it, if not they launch a key management utility which allows enrolling the hash or key.

When run, shim tries to launch grubx64.efi. If MokList does not contain the hash of grubx64.efi or the key it is signed with, shim will launch MokManager (mmx64.efi). In MokManager you must enroll the hash of the EFI binaries you want to launch (your boot loader (grubx64.efi) and kernel) or enroll the key they are signed with.

I also tried to add mmx64.efi and grubx64.efi to the trusted files in BIOS, but I got another error (i.e., shim_lock protocol not found). I was not doing anything special related to secure boot to boot my USB drive before (even when I installed my first Linux distro). Why can't I do that now?

The second layer of blame here lies with the creators of the hardware and the software/OS. In this instance it appears to be Lenovo that had shims available for this group to find, then Google for creating a boot system that could be compromised with access to and modification of shims.

Just a few techs talking about the Chromebook repair menu, and they started talking about shims. These kids were lurking there and realized this was the real starting place. If they could just get a hold of some shims, they might be able to engineer the process further. And the rest is history.

AIO Boot uses Shim (bootx64.efi is renamed from shimx64.efi) to boot at the first stage. Then Shim will load Grub2 (grubx64.efi) in the second stage. You can find lots of useful information about Secure Boot on Ubuntu and rEFInd.

I understand that I would need to

- generate a key pair

- roll the public key into bios

- build the shim

- sign the shim with the private key

- set a boot entry with the new shim and updater as its parameter

- try to boot via this new boot entry

The verification of the Stable Release Update for shim has completed successfully and the package is now being released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

Using @sj's method (and obtaining the device-id via `fwupdmg get-devices`) I managed to install one of diagnostics update. Upon reboot, fwupdmgr told me only one update was outstanding: the tpm one. So: the Logitech update had disappeared; and the TPM update remained uninstalled. One can see from the issue tracker for fwup that Lenovo TPM (or 'ME') updates are notorious for not installing. See: -lenovo/issues?q=tpm+is%3Aissue+is%3Aopen+

Please remove dependency on python-argparse-shim. This is not needed at all. python-argparse is part of core python. python-argparse-shim is only there for packages which have not been fixed yet and still depend on python-argparse, to fulfill their dependency.

Lenovo's support documentation [PDF] explains it thus: "Linux distributions use a Microsoft signed 'shim' executable that is then able to verify the subsequent boot stages that have been signed with the distribution key. The Microsoft signed shim is signed using the 'Microsoft 3rd Party UEFI Certificate', and this certificate is stored in the BIOS database." 17dc91bb1f
