I managed to get downgraded to A09. The link was broken at DELL site for the Panel Touch Firmware on Dell Venue 11 Pro 7130/7139 Version 1.0.5, A02 6/26/2014
<ADMIN NOTE: Broken link has been removed from this post by Dell>
but I found the file on other site: 7130_Firmware_5D22V_WN_1.0.5_A02.EXE
Error message is: Unable to locate a Synaptics Touch Controller.
I have one I2C HID device marked!
