UBI installer for Linksys e8450/Belkin RT 3200

I moved to OpenWRT specifically for DFS... It was a big headache getting 5 WAPs up and running with the ability to distribute VLANs concurrently on Linksys WRT3200ACMs. I know there is and probably will be a driver issue with the Marvell chipset going forward (ie the switch issue with linux 5.10). So I've looked at the Linksys e8450/Belkin RT 3200 with the MediaTek chipset. I don't use OpenWRT as a router, I only use it for WAPs and need the wan port reassigned to the switch for back-haul and 4 ports for the VLAN distribution to remote locations.

I've found several whitepapers and videos regarding the use of a UBI installer to change the memory structure and allow the use of stable OpenWRT releases to be loaded. All sounds good.

My question is: Is this just a one way conversion? Can you ever revert back to stock/OEM frimware? I don't know that I would ever need to do that for my use, but eventually I'll probably want to move to WiFi-7 hardware at some point and it would be nice to be able to put the factory software back on the e8450s to sell them when the time comes.

Thanks for any input,

It’s possible to sell devices with OpenWrt installed and reset to defaults.

You can revert back to stock, as long as you've made a backup first https://github.com/dangowrt/owrt-ubi-installer#restoring-the-vendorofficial-firmware

Thanks, Sam.
I'll archive that and hand onto it.
