Update/Downdate 6000XP Firmware at Remote Location – Page 2 – 6000XP

I operate one 6000XP inverter and two EG4 280AH Indoor WallMount batteries at a very remote location that has no grid power or cell service available. I don't have satellite internet service (though I probably could). The inverter is running firmware version ccaa-190D0E, and I do not plan to update, because ccaa-190D0E works fine, most of the later updates don't affect my usage, and many 6000XP users have experienced problems with the later versions. If and when I decide to parallel a second 6000XP with the first, I will either want to update the older inverter's firmware OR 'downdate' the new inverter's firmware to ccaa-190D0E. I have the EG4 mobile app on my smart phone and the 6000XP wi-fi dongle, and I understand the 6000XP firmware can changed with the mobile app and wi-fi dongle.If I want to update the firmware, is is possible to:1. download the newest firmware to my phone, when I am home and have a normal internet connection,2. turn off the phone,3. travel my remote site, and 4. update the 6000XP using the phone app and the firmware files stored on the phone?If I want to downdate the firmware on the newer inverter , is it possible to:1. copy the ccaa-190D0E files (which I have) to an appropriate folder on my phone,2. turn off the phone,3. travel my remote site, and 4. update the 6000XP using the phone app and the firmware files stored on the phone?I am asking on behalf of myself and several members at DIYSolarForum.com. Thanks.

Thanks for your interest, but it's a bit more complicated. My existing 6000XP installed 500 miles from home at a location with no available grid power, no landline phone service, and no cell phone service. Hence no available internet, unless I spend more money to get satellite internet. Doable, but why should I have to do that to change the firmware on a 6000XP?

The existing inverter is running the original firmware (ccca-190D0E) just fine, and I am inclined not to upgrade it, because I don't really need any of the newer features and definitely not any of the newer firmware problems. But, if I get a second 6000XP to parallel with the first, I am trying to figure out how to downgrade the firmware of a new inverter to ccca-190D0E at home and then haul the new inverter 500 miles to my site for installation.

At home, I can hook up AC power to the inverter's GRID input to power the inverter and connect it to the internet. Then EG4 could downgrade the firmware remotely via the internet. . But, it also needs power to the PV input in order for any firmware changes to take affect on the MPPT, and I don't have any solar panels at home to connect to the PV input.
