I'm trying to re-install the system on a RB5.
The system image I want to install is 1.0.5-M0052-9.1-perf-c, and the current system is 1.0.3-M0052-9.1-perf. 

I get the following error messages when running flash-full .sh(1.0.5-M0052-9.1-perf-c):
[INFO] version: 0.0
[INFO] adb installed
[INFO] fastboot installed
[INFO] qti-ubuntu-robotics-image-qrb5165-rb5-boot.img present

[INFO] Saving test sig
/usr/lib/rfsa/adsp/: 9 files pulled. 6.1 MB/s (4505752 bytes in 0.710s)
[ERROR] test sig failed to save

It seems like the script is trying to backup some files, but the files aren't there.
What should I do to install the system image 1.0.5 properly?

@andyh What is the serial number of your RB5. It should be on a sticker with a barcode in the form M2100000***

It seems as though your system is missing both the camera calibration files as well as the testsig which is required for PX4 to run properly. 

I can check to see if we have your RB5's files backed up in our system.

@tom it's M2100000CU4

@andyh Okay great, we do have your files in our database. I will send you your files via. an email to your account registered here in the next few minutes.

Here are a list of the files I will send you:
- testsig-0xbb02a75f.so
- opencv_stereo_extrinsics.yml
- opencv_stereo_intrinsics.yml
- opencv_stereo_rear_extrinsics.yml
- opencv_stereo_rear_intrinsics.yml
- opencv_tracking_intrinsics.yml

The steps you will do to fix your issue are as follows:

- Download all of the above files
- Create the `/data/modalai` directory on your RB5 with `adb shell mkdir -p /data/modalai`
- In your terminal, navigate to the directory where you saved the above files
- Push the camera calibration files to your RB5 with `adb push *.yml /data/modalai/.`
- Push the testsig file to your RB5 with `adb push testsig*.so /usr/lib/rfsa/adsp/.`

After doing this the flashing script should be happy.

It seems as though those files were somehow lost, possibly due to a re-flash with an older version of our script (newer versions such as the one in `1.0.5-M0052-9.1-perf-c` save these files during the flashing process)
