Firmware update 1.7.6
Massive list of improvements and enhancements. Highly recommended and a definite upgrade from 1.5.8.
The Apple App Store and Google Play have also updated the Goal Zero Power app to the new versions in early December.

My 4000 doesn't show the 1.7.6 update as being available. Any tips on how to get it to update?

My update process is ugly. It's on the "Firmware update 1.5.8" thread so I won't repeat it here.
I've not tried it yet but there is a new user guide with troubleshooting and firmware update instructions here:
Home > Support > User Guides > Yeti PRO 4000 & Tank PR0 4000 Troubleshooting Guide
Force a Firmware Update
If the Yeti attempts and fails to update—or if you need to manually update from the Yeti itself—ensure it is connected to a 2.4 GHz network with Internet access. Press and hold down the PAIR button for 10 seconds. After the Yeti beeps a second time, let go of the button; the Yeti will then attempt an update. -
… and just where is the PAIR button on the 4000 Pro? I don't see it as a physical button on the front panel, and I don't see it described in the user manual. Turns out it's on the back panel under the right-hand (looking at it from the back) flip-up door.

I should have mentioned that the PAIR button is your friend. Keep it accessible and get used to using it, often. It's got many uses: forcing a firmware update, internal resets, and just simply getting the mobile app to 'see' the Yeti via Bluetooth or wifi.
Any luck with the new update process? Were you able to install 1.7.6? (I installed 1.7.6 months ago before they removed it and reverted back to 1.5.8)

Hadn't had occasion to use the PAIR button since I first set the thing up. Nice to know some of its functionality. I tried the 10-second press until the system had beeped twice. Afterward the system stayed on 1.5.8, and 1.7.6 still did not show up as an option. I'll wait a bit and watch for it.

Looks like 1.7.6 was recalled and firmware 1.7.7 is available 12/16/24.
I was successful in my 1.7.7 install … with one major hiccup. GZ states in their troubleshooting guide their devices need a 2.4 GHz wifi signal. My newer router transmits on BOTH 2.4 and 5 GHz (split band). My Yeti couldn't lock in on the 2.4 signal and would time out. Luckily I still had my old 2.4 GHz router and once I switched to it, the 'cloud connect' piece worked fine. There are likely ways to shut off the higher 5 GHz band in your router settings but this worked for me.

I've spent 3 days in my spare time attempting to pair my 4000 with wifi. It was not easy, I read every post I could find and place one unproductive call to tech support (move your router closer to the YETI, thanks for calling).
But, perseverance paid off. Initially using the goal zero app on a iPhone 13 I was able to direct connect with Bluetooth, so far so good. The firmware update from the factory 1.0 to 1.7.7 was bothering me to complete but connecting via wifi/cloud would not work no matter what I tried. Success finally happened when I downloaded the app to my MacBook and established a connection to the cloud. I used a dual-band wifi router repeater in the 2.4ghz range especially to keep the yeti happy. My home router, nor starlink worked. WPA2.
The next problem once the updates started to the yeti were next. The update, repeatedly stalled at 66% from the 1.5.0 update. I forced the unit to update on its own by holding the pairing button down until the second beep and the same problem kept occurring. I powered the yeti down several time for :30, disconnected everything, removed the app from my iPhone reinstalled it and eventually it went through. 1.7.7 and finally done.
Don't give up, keep trying all the posted methods, switch devices, etc and cross your fingers. It should eventually connect and update.
Good luck.
