Recovering a Bricked Uconnect 8.4 after failed Uconnect software update. While attempting to install “SIRI UPDATE FOR UCONNECT® 8.4A_RA3_16.13.13_MY13_&_M14” via a USB flash drive, I encountered the error “Sierra Wireless: bolo file install failed”. The update process went smoothly up until Unit number 10 of 11. At step 10, Unit Name: Embedded Air Card, the process was stuck at 1%, and eventually timed out with the error “Sierra Wireless: bolo file install failed“.
The following picture shows where the software update stuck:
And this is a picture of the final error after timeout:
After the Failed Uconnect 8.4 Software Update, the update process would loop while the USB flash drive was inserted. When I removed the USB flash drive, I was constantly prompted to Please Insert Update USB. It appeared the failed Uconnect update had bricked my Uconnect 8.4.
Note: It is obvious that bad embedded air card was the reason why the updated failed to finish. But at this point I simply wanted to get my Uconnect system back to partially functional order until the vehicle could be brought in for service. For the simple reason that there are several touch controls on screen that do not have physical control buttons or knobs.
How I unBricked uConnect 8.4 after a failed update
How I finally unBricked Uconnect 8.4, and successfully booted back into a functional Uconnect system.
- Turn Key to the Run Position.
- Insert update USB when prompted.
- Remove USB Drive while Uconnect is checking the integrity of the ISO (during Pre-Update ISO validation).
After this process, Uconnect successfully booted back up, and I was able to use Uconnect while waiting to schedule and get my vehicle in for service.
This simple solution concludes how I recovered from a Bricked uConnect 8.4 after a failed update. Hopefully it helps you!
