Finally... The touchpad works great!

[moonwalkers]

Didn't work for me. I took a screenshot of the terminal output figuring it'd help but there's no way to attach images directly to the forum.

Code:

>>> Verify mismatch: type=f2, pass=e2, received=d2
EEE Touchpad verify data failed type:242 pass:226
EEE Touchpad erase failed
>>> USB device closed

The verify mismatch line gets spammed a hundred times before finally giving up and outputting the last three lines. My keyboard is ANSI, but my PBP is a first-run ISO model. I wouldn't think that there'd be ISO trackpads and ANSI trackpads that would cause the script to fail, but I honestly don't know. Right this second the trackpad doesn't work at all and the keyboard doesn't work but certain keys output letters not assigned to them, so it's probably not completely dead, hopefully, fingers crossed. 
Is it fubar or is there still hope yet?

I ran into something similar to this. Unfortunately, I didn't keep notes, but among the things I've done were:

• reboot machine
  
• clean and reset git tree to clean out modified keyboard layouts (I swap LCtrl and Fn to match ThinkPad layout), re-build updater tool
  

After one (or both - like I said, didn't keep notes) actions I retried step-2 and update succeeded. Afterwards I was able to modify the layout .hex again and re-apply it.
