2. Wait for the three LEDs on the CDP to flash. While the LEDs are flashing, press and hold the Power OFF
button on the CDP to enter into failsafe. Failsafe is displayed on the CDP once you are in FAILSAFE
mode. NOTE: If you failed to correctly complete this step, you must reboot the projector and repeat this
step again (wait for the three LEDs to flash and press/hold the Power OFF button). To reboot the
projector, use a small object such as a paperclip to press in the reboot button on the PCM. (Figure 3-43).
3. Once in failsafe, FTP the v1.1 software to the projector and open a web browser to connect to the failsafe
web application. Once you are connected to the projector through the web browser, you should be in the
failsafe web application. Select the v1.1 package to upgrade to and then click Upgrade (this is your second
downgrade to the v1.1 software package.) NOTE: When a downgrade has been performed only once, the
projector will no longer be able to boot into Main code. Failsafe mode is the only thing you will be able to
successfully do.
4. Once the downgrade is complete, reboot the projector by clicking the Reboot button in the failsafe web
application. The downgrade from 2.x to 1.1 is now complete.
