Issue flashing TCM 2015 Z06 _ Times out

[Andy@A&A]

I had an issue flashing the TCM on this Z06 a couple of weeks ago. The PCM flashed just fine but the TCM timed out and I couldn't get it to finish. I ended up going to my buddy at the dealer and having them recover it.
I thought I was having an issue with my interface so I sent it in and had the credits transferred to a new interface.
So now I have a new interface and cables. I'm using a Macbook Air running Windows Parallels and was scared to flash it again just in case that was a contributing factor.
I got a Windows 7 Ultrabook to tune with, just in case.
I tuned the car (PCM) but was still scared to flash the TCM again. Anyway today I forgot to uncheck the TCM box and it started to flash the TCM . It did exactly the same thing and timed out at 24 seconds. My buddy met me at the dealership and opened up the service area to flash the TCM. (on a Sunday no less)
Now I'm scared to mess with the TCM at all. Any ideas?

Hey Andy that's very interesting try pulling the radio fuse, I'm not sure about these newer models but I know on Cadillacs you have to pull the radio/navi fuse otherwise flashes fail, maybe even pull anything like onstar etc.. if it exists.

It's the software. Every now and then they will break the Beta. I always keep a "known good" copy (old) of the Beta on hand in case a new update erases my TCM and won't reflash it....it does happen. Did you let support know and send them the required info?

No. It was Sunday and I was going to deliver the car to the customer when this happened.
I'll have my 16 Z in a couple of weeks. I'm not flashing anyones TCM until I test on mine a little.
I'll send the info to Bill when I get a chance.
Thanks.

Had a 2015 silverado over the weekend that would time out on tcm if i let it write both the ecm and tcm together. Found that if i wrote the ecm only, then afterwards wrote the tcm only, it would write ok every time. Luckily did not need a trip to the dealer.
