Okay figured out the LaView situation. Have to remove camera from old account first. Nothing special about their apps, so moved back.
As for Nelly's Firmware the latest is 5.2.4 Build 190625. Got it right from Nelly's.
Box
Flashing from LaView firmware to Nelly's caused me to need to reset the camera. This was a bit of a bear. Had to remove the camera from the app because it expected the Wifi being presented from the camera to be HSDB2_deviceserial when using RCA App. For EZVIZ it expected EZVIZ_deviceserial. For Guarded Vision it wanted HAP_device serial. Not until I removed the camera from the App/account was I able to add it back with the Guarding Vision app using what the camera was actually presenting which is "softap_deviceserial" For anyone stuck here the password is "softap_devicepw" This really hung me up for awhile. Even Nelly's was a bit stumped. I did some packet captures and I still can't find the URL for where it upgrades and I tried both the iphone IP and the camera IP. Neither showed me a check at that URL. However I did find a lot of OnVif details in the packet capture in the Nelly's firmware. Here is some of the decoded text from the UDP packet for the onvif stuff.
