It seems to have worked. I was able to flash with this mod and get video to monitor. When i check with slic dump it shows it has slic 2.1 and matches certificate. I haven't tried windows7 activation with it (I am running 11) but it is good to know it can be done. Thanks for the help guys!!
Whats the output from "SLIC Toolkit"? Dump ok? In your RWe-report SLIC-table is present and valid. Did you install the right certificate-file? You must use the exact matching cert for v2.5, there exists only one cert, name: DELL-DD981F15.XRM-MS
