All I know is, these are the steps I follow using a laptop:
1. Power set to ON
2. Connect to JB4
3. Upload firmware
4. Select the appropriate .hex
5. Wait ~3m
6. Confirm firmware version has changed

No, I do not have an account over there and was able to download attachments from Terry's post.
Finally was able to update my jb4 today. After having their techs jerk me off for 2 days. What ended up working is I uninstalled the app, reinstalled it then tried to download one of the other maps (map 7,8,9) sat the phone right on top of the Bluetooth module and tried 10 again and it went through finally.
Still learning how to use the app and log my pulls but how’s this look guys ? Jb4 Map 1 factory Air box top off 92 Wawa Gas ambient temps 78° 100% humidity NGK R2556G-9 .024 T9210 GFB Bov 
92? I know you have 93 in PA. Capture third gear pulls from 2500-6500 and attach .csv logs.
I had to use 92 due to it was all that was available in a pinch. 93 is available but harder to come by. And will do !
Will the site not let you attach the .csv files? I am definitely not going to transcribe that shite manually.
I can’t from my phone. It only lets me take a screen shot or email it. The file doesn’t copy it just copies a screenshot. I can try on my laptop when I get home
So glad I chose the old school hard-wired method of using a netbook, even if it is cumbersome to manage in the cabin. I’d be pulling my hair out with that app not allowing saved files to be accessible for offloading.If you can’t attach them, try this site:

The app does save the files, it also lets you email them directly from the logs page. You can't upload CSV files to this site directly, you need to host it externally and post a link unfortunately...
how do i go about doing this ? i tried uploading logs from my laptop and no luck
I followed this link and drag and dropped the files to the box now how do I share it with you guys ? sorry if this is a stupid question I just see no obvious ways of sending the url or files from this website.

Right-click while hovering over the blue “Download” button and copy the link. You can then use a URL shortener like v.gd or paste the full link here.
