Thanks OpenWrt SNAPSHOT r17747-9d994f35b4 is now available and running on one in AP mode. (got two) Initial report running fine for an hour. Al sort of unicast/broadcast issues I experienced with wifi speakers seem to be sorted, radios work..., association issues sorted. Before this commit it was hard to initiate a stable connection now it seems things are stabilizing again. Time will tell. Not setting expectation to high as it remains snapshot of course.
I will get the dumps shortly and as well attempt the recovery install as before with the most recent installer.
@daniel Apologies, it seems that I cannot do PM's. I had to create a new account yesterday as my old account was no longer on this board. Is it possible my account is too new?
I got my RT3200 directly from Walmart for $95 + taxes and shipping to my country.
I second this issue. I flashed non-ubi before and lost access to it so I reverted back to the factory version. The router is acting today so I was going to give openwrt another try, yet the image listed in the device page was not working and I'm back to factory firmware. I'm not sure if the latest factory blocks openwrt, or if my nand was bad so bootloader kicked me back to factory after 3 fails.
Was performing fine until lot of

This is on an e8450, before I force flashed with 0.5.3

then flashed

The e8450 always had the
hexdump: /dev/mtdblock2: I/O error
I've got a RT3200 as well which does not throw this I/O error which had the same upgrade process.
Q. Is there anything conclusive to say about the i/o error. Is there a diff in hardware. Suppressing these msg is a workaround right? And it seems it has some other side effect on the operational status in general.
Other then that will try to look into it closer to try and find out under which conditions this is occurring and create ticket with hexdump, dmesg, version, logs, etc.
I am wondering if the non-ubi builds could be broken? Or like you said, the new factory firmware could have some sort of protective measure built in that would prevent a non-factory image from being flashed. Anyone else encountering this issue? My RT3200 has factory firmware version 1.0.01 build 101415 OCT 14, 2020.
I just found out about this router. I did not think openwrt worked on any wifi 6 AX router. I have a gigabit connection from Xfinity. My Netgear r7500v2 is struggling to keep up. I was wondering if the Belkin rt3200 would be a good router for my gigabit connection? I plan to pair it with two Cudy AC2100 routers configured as APs flashed with openwrt.
I have a gigabit connection as well and 2 Belkins, they are working great, no complains here.

Awesome thanks for your response. I am going to go ahead and grab this for my main router to replace my r7500v2. Is NAT offloading supported?
Yes, there is! It's experimental (it says on Luci) but I believe it is working well ( I don't use QoS/SQM, though)

Awesome thank you. I am getting this router for sure then. Later I think I will upgrade the Cudy AC2100 AP's with these as well. I wish I could find a place to get them for $50 to 75$ as some people claimed they did. I would buy three right now for that price. However, the cheapest I have found is for the Belkin version for $99.99 at Walmart.

I would recommend checking the Belkin website periodically. I bought two there when they had a 20% back to school promotion (each one costing $80 after the discount).

Most recent update is now giving segfaults, but no longer forces a reboot. This is happening to 2 of my Belkin routers

You might want to check this thread again. There are report that with SQM the router can only do around 500-600 Mbps. Without SQM you obviously get 1G though.

Okay WtH is go is going on with not being able to flash any sysupgrade non-ubi image like the wiki says for this device from the factory firmware? 
Has Belkin updated their firmware to not allow this? I remember Linksys pulling a stunt like this with their EA8500 so that you had to using a USB serial cable to load an older firmware before you could flash dd-wrt.
Oh no I hope not I just ordered one from Walmart and will have it tomorrow or Sunday.
Just go with the UBI conversion. Much better option all over.

No, this is not deliberately caused by Belkin or Linksys. The firmware on devices bought today is still from October 2020 (version 1.01 afaik), there was no OpenWrt port back then...
The problem is that the (previously hacky/messy) SPI-NAND driver was replaced/updated with a rewrite by MediaTek which is a shared implementation used in TF-A, U-Boot and Linux (which makes maintainance much easier in the long run).
(Un)fortunately the new driver gives error correction/detection feedback and apparently the OOB data is different depending on which driver is being used. So while everything written before the switch is still readable the driver reports fixing bit-flips which results in mt76 and other not using data in flash which was written in factory.
When using the UBI variant the installer itself takes care of that and re-writes the relevant parts of the factory partition (and anyway removes/replaces everything else). To use the non-UBI build you will have to manually re-write factory partition (ie. attach serial port, interrupt the bootloader and load initramfs via TFTP, then read and write back factory MTD partition) as there is no other way to do that right now.
