[mutually exchanged pleasantries and conclusion of call]
</pre>
== Follow-up Support Call ==
@15:00 hours on a Thursday call support phone number provided.
10 minute call with D.
<pre>
>> Hacker says...
I'm repairing a machine and have followed the directions from support earlier.
I'm still having some issues getting the machine to start up.
I've replaced the blown Thermal Fuse and looking for the reset procedure.
The device has gone from a 0x6 error to 0x5 with a Later option.
After doing the initial start up homing it lands on a error message about too hot.
{Further discussion about connecting to the internet and using the app for support}
{Discussed various reasons this isn't an option, asked about off-line update options}
Can you provide updated firmware so I can attempt a update via USB Thumb Stick method?
>> rotomatic says...
{Some consternation over who/how the machine was opened and repaired}
Send an e-mail to support with your information for additional follow up.
{Discussed a few other details and concluded call}
</pre>
== Support E-mail ==
* Sent an e-mail to support [at] simplistic [dot] com with general inquiry for firmware
* Got an instant automatic response to the inquiry
* 2 minutes later Jason messaged that they were looking in to it
* A few minutes later they sent information on update and copy of firmware
** Intructions:
*** Use 16GB or smaller USB Thumb Drive (Worked with 512MB)
*** Format with FAT32, not quick format (Worked with FAT16)
*** Extract Zip file
*** Copy <code>update.img</code> to USB Thumb Drive
*** Insert USB with machine unplugged
*** Plug machine in, wait 60 seconds (should here ~20 sec tone)
*** Machine should reboot itself, usual quick beep
*** May still have invisible error <code>0x5</code> press 4th button "Later"
