Greets,
Looking for validation of my plan to update ol' 12000xp from ceaa-0202 to ceaa-0507 offline please.
12000xp currently exhibits seemingly random bouts of fast fan syndrome when solar power is connected. Internet connection not available.
Finally figured out to logout from EG4 Monitor on Android to access Firnware Update. Downloaded two files consisting of ceaa-0507.
The dongle serial number appears in my Bluetooth devices list and I am ready to pull the trigger to install the update via Bluetooth.
I plan to put ol' 12000xp in standby first.
Kindly validate my plan as we all know what happens when firmware updates go awry and it ain't pretty.
Many thanks,

Sounds correct. If you need any further assistance, please let me know.

Thanks Eric,
Just out of an abundance of caution, the screenshot instructions you attached largely don't apply since I'm using Bluetooth without an Internet connection. I do not have three lit LEDs on the dongle; I have one flashing green on the wireless icon.
Still good to go please?
Thanks again,

I apologize for the confusion. You are correct.

How did the upgrade go? Did it work from Android properly?

It did load from my android's Bluetooth, not sure how it would've gone without a concurrent 4G connection on my phone though. I had to stumble on to the Bluetooth connection becoming active only when the wifi dongle was installed.
When solar is being generated, rather than the fans gently varying to stabilize generated heat, I occassionally hear the fans launch to whizzing high for about a minute then pull back to low. Was hoping the update would address this but no.
Other than the fan speed concern, the system is running great. Still looking for control commands to become available as with some other EG4 models.
