Firmware Flash to Clear the SMMSTORE ROM (Error code 5)
Things that you will need
- 1-2 flash drives (1GB and up)
- Philips Screwdriver
- Approx. 30 mins.
The error messages
If you are seeing any of these messages on your Open Firmware system:
configuring bootloader error: command failed with exit status: exit code: 5
errored while installing system: command failed with exit status: exit code: 5
calling Schedule method failed: "failed to add boot entry: exit code: 5
system76-firmware: failed to schedule: failed to add boot entry: exit code: 5
It may be necessary to clear the SMMSTORE ROM by flashing new firmware using a flash drive with a custom firmware update tool. After flashing, this will remove any custom EFI variables (such as those installed by boot managers). Information on repairing the bootloader can be found at the end of this article.
To begin, download the zip file for your system below. Unzip the files to a FAT32 formatted USB drive. Then, shut down the laptop and remove all NVMe M.2 drive(s) in the system using the step-by-step instructions for your system:
| System | Patched Firmware | Tech Docs |
|---|---|---|
| Adder WS (addw2) | addw2-76ec.zip | addw2 |
| Bonobo WS (bonw14) | bonw14-76ec.zip | bonw14 |
| Darter Pro (darp6) | darp6-76ec.zip | darp6 |
| Darter Pro (darp7) | darp7-76ec.zip | darp7 |
| Galago Pro (galp5) | galp5-76ec.zip | galp5 |
| Lemur Pro (lemp9) | lemp9-76ec.zip | lemp9 |
| Lemur Pro (lemp10) | lemp10-76ec.zip | lemp10 |
| Oryx Pro (oryp6) | oryp6-76ec.zip | oryp6 |
Unzipping the Files
Depending on the decompression method being used, there may be an additional step. In some cases, the unzipped file is moved into a folder with the same name. For example, "oryx6-76ec.zip" becomes a directory called "oryx6-76ec" instead.
The mainboard will not know how to access the files inside the directory. The firmware flashing will not work in this case. Instead, move the files outside of the parent directory, delete the parent directory, and try booting again.
Pop!_OS extracts the files correctly by default (see screenshots below), but other extraction tools or other operating systems such as macOS may behave differently.
The highlighted files pictured below (the hash will change based on file and model) are the two items that should be in the root of the USB drive.
With all drive(s) removed, replace the cover and boot with the USB stick inserted. After the firmware has been flashed, remove the USB stick and reinstall the drive(s).
Once the system is put back together, it may be necessary to boot with a live image in order to repair the boot loader, if you dual-boot with Windows 10. Step by step instructions are located below below:
