Hi, Anyone in the Houston area that can help update the firmware on my TinyG board? 
Windows user? Try this: https://groups.google.com/forum/#!topic/devtinyg/B9xSJaupzNQ

Roo- the other day Eric Lien, a good friend along with all others listed above, ran through this. There was a slight “shuffle of the feet” required. As Eric sent this to me on hangouts I hesitate to post it as it is not mine to share.
I will note, I’ve ran without updating for what feels like month, without issue.
@Brandon_Satterfield please share of course. Otherwise I could do the same.
@cmcgrath5035 wish I had found that when I ran into issues. That’s exactly what I did.
Hi, Yes I’m a windows user. I tried it but no luck. I will have to go through all my programmers and see if I have the mkII they call out on the troubleshooting page.
@Evaristo_Ramos can you elaborate on no luck? Where did you run into issues?
Ok guys, I got the firmware updated finally. I had to use chilipepper to set the TinyG into bootloader mode and then quickly stop the server so i could run the updater.
Next issue is figuring out the $nTR values as I tried all different ones from around the web, with no success thus far. I have GT3 pulleys & belts, with NEMA 23 motors. Suggestions?
@Evaristo_Ramos Did you try the reset button on tinyG? If you have a bootloader, that sort of has to work. Perhaps you still had SPJS running, which will block avrdude’s access. But good, you are upgraded.
If pulley is the popular 20 tooth, then $nTR=40 should be good place to start.
Due to a bug that appeared in 440.15/.16, you have to reset tinyG for a change in $ntr to “stick” (be used).
SO:
$xtr=40
$ytr=40
cntl-X or reset button
Bugfix in works, expect >440.16 soon
Hey Roo- 40 for x and y, 8 on the Z.
Use a fine point engraving bit or something extremely sharp and draw or cut a large square on your spoiler board via the machine. Physically measure the drawing or cut and verify you are cutting what you created in the CAD software. It will require fine tuning if you want your machine to be as accurate as possible.
An example, I believe one of my machines is set at 39.96 for the X and Y.
Woot!! Those worked. Now off to find tutorials on how to set my Z. Thanks All!!
@cmcgrath5035 Thanks so much for sharing this post. I was reading about this method on the TinyG Wiki but that post made it so much easier to understand. I was able to successfully flash my TinyG with new firmware thanks again!!!
