After recovery your VCM2 should be at VCM2 FW version 2.1.1.5.<\/p>\n<p>3. Wait about 90 seconds after the VCM2 beeps before proceeding. We are waiting for the SD card to be populated.<\/p>\n<p>4. Unplug the VCM2 and eject the SD card.<\/p>\n<p>5. Mount the SD card with a linux machine.<\/p>\n<p>6. On the SD card open \u2018apps\/vci-diags\/hwtest-scripts\/self-test.sh\u2019 for editing.<\/p>\n<p>7. Add the following line to the file:<\/p>\n<p>touch \/etc\/vci\/config\/testmode<\/p>\n<p>8. Cleanly unmount the SD card and insert it back into the VCM2.<\/p>\n<p>9. Plug the VCM2 unit into the computer and wait 90 seconds past beep before proceeding.<\/p>\n<p>10. Launch IDS.<\/p>\n<p>11.
