LLY write issue

I am trying to delete the VATS in a 2005 LLY and am having trouble writing the file back to the ECM. I did not have any issues with downloading the file. Made my changes and went to write the file back to the ECM, after the progress bar made it to 100% it says failed. I have removed radio and AMP fuses, tried with TCM connected and disconnected, cycled power to ECM several times. I have tried multiple times, with various different fuse arrangements, still no success. I have tried low speed, high speed, and now have not file in the ECM due to the delete process of writing. Just wondering if there is any magic combination that people are getting to work.

That?s all it says is just Failed?

No x code to the left of the status bar?

I thought I took a picture of the screen, but must not have. I?ll check when I get back home this evening.

No X code. But it does say "Writer Verify: Failed"
