can you try these? You can just flash the sysupgrade over your current installation:
openwrt-ipq40xx-generic-meraki_mr74-initramfs-fit-uImage.itb
openwrt-ipq40xx-generic-meraki_mr74-squashfs-sysupgrade.bin

You are my hero! It works! Thank you soooo much! I will do some testing to see what is and isn't working an update from there. You guys are my heros. Thank you all for all the assistance!

Would it be safe to say I have the first and only MR74 on OpenWRT?!

Yes it would be fairly safe to say, since there aren't many of these devices around and users wishing to install OpenWrt onto them. Can you confirm if your MR74s were recently connected to Meraki and updated? Also I am assuming that you didn't need to use a NAND clip? If so this may indicate that these devices aren't being locked down like the MR33s.
It was updated and I do have a 360 clip with a NAND flasher. I wish this device wasn't locked down it would make it so much easier. Considering the many uses of the MR74 I would say it is worth the price of a 360 clip and NAND flasher. About the only difference between the MR33 and the MR74 is the frame and the that it uses only one "external" wifi controller.
When you created this image did you use the MR33 base to it? I don't have access to the radios at the moment for some reason

Well this maybe a hardware failure issue I have had it in and out of the frame and possibly had little hands all over it.
I made a mistake in the sysupgrade image I sent you. Could you please do the following:
edit file /lib/upgrade/platform.sh using vi
go to line 168
where it says meraki,mr33), change this to look like:
meraki,mr33 |\
meraki,mr74)
and save the file. Here is the diff.
I have updated the images in the box.com URLs. You then need to redownload the sysupgrade from the same URL and flash it. You'll then have wireless working again and be able to upgrade as normal.
Let me know if you have any issues.

Ok so just using the standard bridge seems to work just fine but when I try to do VLAN per SSID it doesn't work.
Do you know if it is possible to get a page for the MR74 like the MR33 has and have it updated with new firmware as it is released?
Since Meraki's already in the hw list, you should be able to request a wiki account, and add the page yourself.
How would I go about building a new sysupgrade bin for a device?
The MR74 is now included in the development snapshot builds so you might not need to build, depending on your use case. Otherwise you can follow the instructions on Github.
I see that the MR74 isn't in the snapshots. How do I get a stable release to install on my MR74? I have hit a point where I can't add WPA3 stuff to it due to an old package that can't be removed and has been removed from the tree.
Also it would be nice to have dawn and usteer as well
If a package is available in operwrt, simply install it ?
On the version I currently have it isn't an option. Plus the options that need to be enabled to use both Usteer and DAWN aren't there. The options don't show up on the SSIDs. If I knew how to modify an existing MR33 release like 22.03.5 to work on a MR74 I would but I don't. I have used image builder to make one but I lose my LED config and only the orange color works and it breaks my VLAN per SSID config that I ave working. I am able to use my MR33 with a latest release with VLANs, DAWN, USTEER, ect but can't with my MR74.
@phantomstranger could you send me your dump of mr74. It seems i fried my mr74 flash while i desoldered, programmer reads only zeros.
