What is a USB repair shim?
You can create a USB repair shim by writing a repair shim image to a USB storage drive. With the USB repair
shim, you can:
• Refresh the Chromebook system with the latest firmware.
• Diagnose problems and restore the system to factory settings.
Note: Before replacing any FRUs, use the USB repair shim to diagnose and identify problems.
When you use the USB repair shim to diagnose problems, the Chromebook enters the factory-test-image
environment and runs through the following factory test items.
Table 1. Factory test items
Test item Description
Final Functional Test (FFT)
The FFT is designed to test the function of individual component, such as the display,
audio, camera, and keyboard.
Some test items might require an HDMI
™
monitor or SD card. If the devices are not
available, the tests can be bypassed. As a result, the overall test is marked as failed.
RunIn and FAT
The RunIn and FAT are designed to test how the system functions under stress by
running the maximum workload. It takes about 10 minutes to finish.
Google Required Tests
(GRT)
The GRT is designed to check the system status and help reset the system back to
factory settings. If any test fails, the GRT has to be forced to end.
Create a USB repair shim
Step 1. Prepare a USB storage drive with at least 8 GB of storage capacity.
Attention: The creation process deletes anything stored on the USB storage drive. To avoid data
loss, backup all the data that you want to keep.
Step 2. Download the image file of the repair shim from
https://support.lenovo.com. A Lenovo service
credential is required to download the image file.
Note: Make sure to download the latest version of the image file. A shim created with an earlier
version of the image file might cause the repair process to fail.
Step 3. Use a disk imaging tool to write the downloaded image to the USB storage drive. An open-source
tool Win32 Disk Imager is available at
http://sourceforge.net/projects/win32diskimager.
