Good to know. Odd he would not look at tickets, but I am sure you know best as I did open a ticket for the Switch Config issues and it was not closed.
Hopefully he will see the post about the non-booting r57200. It is very verbose as I am sure you saw it. Not sure what more information I can provide.
That aside, I got a PM from another long time forum user this evening asking what version of the factory-to-ddwrt file I had used for this router. I only have two in my mr7350 folder and told him it was one of those. He reported the one posted in the OP didn't work for him, but I am pretty sure that one works, for me at least. I am going to revert back to stock OEM once again and double check it for him but there may possibly be slight differences in different country versions of this router. No idea why it doesn't work for him. _________________ - Linksys EA8500: I-Gateway, WAP/VAP 5ghz only. Features: WDS-AP, VLANs, Samba, WG, Entware - r59429

I have verified that the factory-to-ddwrt file posted in the OP does not work due to the "Entity too Large" error. I took the router fully back to stock before doing this, of course.
@hebeda This file download should be changed to one that works (r56941).
The factory-to-ddwrt r56941 does work however. Do not try anything later than r56941 at this time. It will not boot.
EDIT: After further testing (see below) the OP factory2ddwrt file can be flashed. If it fails, reboot and try again. _________________ - Linksys EA8500: I-Gateway, WAP/VAP 5ghz only. Features: WDS-AP, VLANs, Samba, WG, Entware - r59429

I was informed that BS hasn't been testing builds on his MR7350, and I linked from post #70 (own3mall's query regarding switch config tab) forward in reply. He may ask for more info or not. Also, MSOE has mentioned that port 1 will give filesize error whereas flashing from port 4 will not. Guess we will find out soon enough.

Very interesting indeed! I will also test this myself while monitoring via serial. _________________ - Linksys EA8500: I-Gateway, WAP/VAP 5ghz only. Features: WDS-AP, VLANs, Samba, WG, Entware - r59429

MSOE kindly provided me with test build r57256 and it does behave differently than r57200. It does get past uboot then hard crashes a few seconds later, then hangs at uboot for a minute or two before trying again. With r57200 it would literally shut down the motherboard like a software power down. No lights, no nothing with no attempt to reboot whatsoever requiring a power cycle to get it back.
-----------NOTE---This is the hard crash ^^^ ------------------------------
Then after the hard crash, here is where it hangs for a while.

I tested this extensively and my results were completely different than last nights attempts. Which in itself is extremely odd as I used the same exact two files (OEM and F2dd). Last night the factory-to-ddwrt file from the OP did not flash with the Entity too large error (plugged into router port 1). Today is different.
Full reset of both partitions to factory OEM.
Flashed factory-to-ddwrt r56746 using router port 1 -- SUCCESS
Again, full reset both partitions to factory OEM
Flashed factory-to-ddwrt r56746 using router port 4 -- SUCCESS
I also tried this while alternating partitions. Worked every time.
I don't have a fscking clue at this point what's going on. _________________ - Linksys EA8500: I-Gateway, WAP/VAP 5ghz only. Features: WDS-AP, VLANs, Samba, WG, Entware - r59429

Glad to see this is getting attention, kinda funny to see the wiki saying the Min. usable version is 57200, because i said more than one cuss word after trying to update to it thank goodness it rolls back. Also not sure if this issue has been mentioned but when I'm ftp'ing to my ps4 but the 7350 seems to be locked to 100mbit (r56941,pc wired, ps4 wifi). I do look forward to the next release last month i was tired of using pc as hotspot and motivated by ddwrt getting affordable ax router support but now the wiki's 7350 status as a work in progress is something i must accept maybe this will motivate me to revive my Nighthawk X6 R8000, tried several times to reflash on powerup and it would start but not finish.

Sorry, I am not paid any money, nor is anyone else who edits the Wiki. That being said, the Supported Devices Wiki clearly states:

DO NOT TRUST THIS LIST, NOR THE ROUTER DATABASE, TO HAVE THE MOST UP-TO-DATE INFORMATION!
wasn't trying to nit-pick or come off as ungrateful, just finding the humor in something small. I know a operation of this size takes a massive amount of time, attention, and dedication wasn't trying to take anything away from it plus it wasn't like it bricked it. Anyone messing with changing firmware especially "beta" firmware should be ready for some unexpected happenings, kind of like the roll of the dice lol though the vast majority of BS's releases are pretty on point(especially considering the number of supported devices). Anyways just wanted to try and clear the air a bit and say there are many including myself that appreciate all the work that goes into the support and creation of DDWRT.

Also, FWIW, there seem to be at least three variants of HW floating around.
OpenWRT has pictures with all the header pins available and soldered in.
I received a used unit off Mercari that had the serial header still soldered in.
Lexridge got a version with no header pins soldered on at all....
This could be due to Linksys having multiple CM's building the router and/or a single CM but different factory locations building the hardware.
It could also be that cost cutting was implemented and every penny counts so the headers were removed to save cost/labor/pick-place work.
I haven't explored the PCB pictures floating around to know if anything else hardware wise changed or not. It also may explain why there is such a mixed result thus far.
I also believe that BS doesn't have this explicit router, but a DSL version of it which will may have some other nuances vs a normal MR7350.... again, we'll get there at some point but for now if you want a simple flash and "off you go" experience- DO NOT FLASH any builds. _________________ FORUM RULES
This is an interesting theory there are multiple variants of this unit and I was suspecting this to be the case last night. Just for comparison sake, here is my serial number:

FWIW, mine is made in Vietnam too.... so most likely the missing headers are nothing more than a cost cutting measure. I can't recall if a new board spin requires new FCC or not; so I have no real way to know if there are multiple rev's of the hardware or not. This router was launched right at covid time, so anything is possible during the 20-22 time range for chips and board revision.
This device is too new for us to pin-point any difference right now among the small reported testers and all three data points I have all show Vietnam; so let's assume the hardware is the same for now and just cost cutting is why the headers are missing. _________________ FORUM RULES

Lexridge, I have been fully able to restore the MR7350 back to stock on both partitions based on your guidance in the previous pages.
It would seem that as BS added commits from the first file hebeda shared on this topic, things have only gotten worse; even with tonight's build of 57294- the router crashes on boot and tries two more times before reverting to the other partition.
Right now DD-WRT on the MR7350 is a no go scenario. Don't bother trying unless you have a serial TTL to usb adapter and can use putty and tftpd64.
I sent BS a dump of the crash from putty.
Now we wait for instructions.
Thank you Lexridge!
and KP69 for you cyber sleuthing skills to find the Chinese website info too.
