When I modified my second one, I straighten a paper clip and slid it under the ribbon to apply a bit on tension during desoldering. I think just using a soldering iron on top with a bit of tension would get it to release. I used a very small drill, just held with fingers to remove the copper at the end of pin 8.I think there was a small via there. I am 2 for 2 success rate now, so it doable.

Quote 5. BLK is now gone and is now CS.

I removed R2 so I could use the BLK pin as the CS pin on the header. Removing R2 disconnects BLK from the LCD panel.

There should be three fonts loaded in the latest release 8x13, 6x8, 4x6.

The font 6 issue is a legacy of some MM+ code, I'll remove it when I do a new release.

Don't understand - prog works for me.

Please try re-loading the firmware with the attached (font 6 issue should be fixed as well)
