It is the FTP server, since that is not a “secure connection” been reading about it at work. Going to use another layer witha GUI, MobaXterm has everything like Putty but more elegant and controllable I am testing on a different computer because of drivers issues and other stuff, will share results soon.

Hello again, after learning about the craziness of TFTP and firewalls. End up doing the process in Windows. And I can confirm another win, flashed both partitions on the board, and I can see the stock firmware.
Uboot is finicky to say the least, also commands are to be put in one after the other, not all at once.
Had to disable all the firewalls and crap in WIN11, but we are back in business.
Thanks to both of you Peppermint and Frollic, for the patience and dedication.

More questions, I know Peppermint shared a stable build for this device, but looking into the latest SNAPSHOT I see version r301044. Have any of you try this version at all?
Also, looking into having a version of SNAPSHOT with Luci, but not sure if that can be build from the FIRMWARE SELECTOR site?
If any of you can chime on that front that will be great.
Thanks again for all the help getting me back on track
Honestly, that is just a build I knew booted to get you back up and running. I have stopped using the mr7350 since I am on my GL.iNet GL-MT6000. DDWRT has issues with wifi-wifi latency, and openwrt without NSS is slow. I reflashed mine with a snapshot, made sure it works, and shelved it for an emergency backup. Eventually, it will be an access point, I think. Yes firmware can be built with Luci. Check the screen shot below, select customise drop down… luci is already selected to be built… run it and download the images. If you try DDWRT - use r61848. that is the last version which is working on the MR7350 - at least at this time. I actually have two of these (a) has openwrt snapshot and (b) has DD-WRT.
I made a tiny hole in one of the slots on the side, and ran the serial wires through it. I put a sticker on the side what color wire is to what connection (gnd, tx, rx). made it really easy to get back in and flash. Some reason why - DDWRT I never have a brick issue, I am having the issues with openwrt snapshots - something flips off with the dual boot not being able to be written. Linux and the serial have become pretty straight forward after a few times, lol. Glad you got it done… not too long ago for me debricking either.
Can you give some numbers e.g. can it do 1 Gb/s LAN<>WAN without NSS but with software offload?
I see, funny thing; I will be using this MR 7350 as an AP too. Also, I am wondering how are you linking the Flint 2 router? (GL.inet MT6000) I keep hearing about them, but I also see for OpenWRT they are still in SNAPSHOTs version.
sorry - I was out all day and just got home. I can hook up the MR7350 (mr7350’s plural?) tomorrow - I am currently on my GL-MT6000.
I am not a coder so I will say what I do have - maybe I can get good data - maybe prove myself a nitwit, LOL. Whatever is the truth is always best.
I have two MR7350’s. One has DDRWRT r61848 (last good stable). I also have a second MR7350 on openwrt snapshot obviously non NSS kernel.
Treat me as I do not know - as I do not… is there a test you would like me to perform with what i do have to compare?
My biggest issues are wifi download speeds from unscientific tests. I only have a 300 down / 40 up cable connection at this time:
From Memory - EDIT cloudflair speed tests below.
getting about 400 mbps on the gl-mt6000
I am getting about 140’s on the openwrt mr7350
300’s on the ddwrt mr7350.
I would have to look at the routers - make them each a gateway to test. I have never done an iperf3 test… unless you think that may give good information I can try tomorrow (easten time US is it late to start testing). Let me know, I will give it a shot is this helps
EDIT: I am a nerd: non scientific test. Dell 5490 Linux Mint 22.2. 5 Ghz, channel 108, 80 Width each setting. Main Gateway Router. XFINITY 300 down 50 up. Laptop did not move from test location.
and the 24.10 snapshot is very stable for the gl.inet gl-mt6000. I posted this also in the proper thread for the gl-mt6000
Your Wifi speed is indeed terrible, I do not think that NSS is helping much for Wifi so something else is amiss either in your settings or in the wireless drivers/boardata used by openwrt.
To be honest a router using ATH11K has use for 1 GB of RAM and the MR7350 "only" has 512 MB so would not be on my list to buy.
I have a Dynalink DL-WRX36 also Qualcomm but with IPQ8072A and 1 GB RAM which runs perfectly fine on OpenWRT
Anyway thanks for sharing your data, for iperf3 testing I use this but your problem seems in the wifi and not the actual throughput:

Definitely wifi. Even on DDWRT (brainslayer has done an awesome job) - the wifi has some issues. Wifi-wan is great, wifi-lan is great, wifi-wifi no matter what channel has massive latency, like 1000 to 6000 ms. I found this out trying to set up the kids minecraft server, worked great on Merlin, and openwrt on th gl-mt6000. Seems with qualcomm the drivers have issues so… I am at the point of walking away from anything that uses those chipsets. I heard now qualcomm is starting to integrate some drivers into the 6.18 kernel. However it seems to be only newer chipsets, 6.18 will be a while yet, too little too late (?). I will see. I will help where I can - but I am not a developer and for myself - I can not beat the gl-mt6000.
also note - it does not make any difference software offloading or none at these low of download speeds. i tested this. and correct the NSS on ECM, off or SFE with DDWRT make no difference these low of download speeds.
Just for everyone amusement, Installed DDWRT on the MR7350, and the Wi-Fi speed is giving me issues with equipment and endpoints. I am back to stock firmware for a while,I am back to stock firmware for a while, I think I will wait until this unit gets a more stable release (this dual partition schema) nobody is a fan of that, lots of people have some of the issues that I am experiencing
The good this is that we all are learning a lot. and Kudos to Brainslayer for all the hard work, to me and other He is a LEYEND. Lots of repect.
Keeping this light here for DDWRT. (A) make sure on MR7350 you download r61848 (at least as of today 15 Sep 2025), (B) do not use SFE - shortcut forwarding engine, use NSS-ECM. Or ask on that forum there. The issue I had with DDWRT is the wifi-wifi latency. Other than that r61848 is really good.
I can share my settings in PM if you want.
This NSS is interesting, developing we shall see how it goes. If I were to consider any Velop I would be looking at the MX8500. However, I scored the gl-mt6000 for $85 so…. I still have the MR7350 and seeing if anything develops. Either way - another successful de-brick. my hats off to all the developers.
I think BS will get to the bottom of this. He is one guy holding the project all up - and that is no small task. the wifi-wan, wifi-lan, lan-lan, lan-wan are all good. Something funky with the qualcomm drivers.
check your usb - it stops working after it has been on either ddwrt or openwrt - until you flash off factory again….
Interesting, glad you noticed that. For a moment I was thinking it was just my device, for now I know is one of the bugs on the SNAPSHOT software.
I forgot to ask you, did you had any sucess flashing the second partition once you were in Openwrt? Because, I have not being able to flash it, following the WIKI:
- First Check booted partition: fw_printenv -n boot_part
fw_setenv boot_part 2
depending on the current partition
mtd -r -e kernel -n write openwrt-qualcommax-ipq60xx-linksys_mr7350-squashfs-factory.bin kernel
- If in slot 2:
mtd -r -e kernel -n write openwrt-qualcommax-ipq60xx-linksys_mr7350-squashfs-factory.bin kernel
Doing that the unit reboots. Then I tried copying the firmware to /TMP/ and flashing using this command: Run sysupgrade -F -n -v 'firmware.img'
Same thing, I believe Frollic was having the same behavior on this post. But to be honest I been searching for a solution and so far nothing. I double checked my syntax and looked at others for similar models, - weird the unit just reboots.
Any information on that will be much appreciated, Thanks
no. Only older versions openwrt I was able to get on both partitions. The latest versions bricked the router and I had to debrick it. Some reason why the flash makes the partion not mountable until I get it back to factory with serial and tfpt. For now I only have openwrt on 1 partition to test if there is development. As for DDWRT, that handles both partitions flawlessly. DDWRT is much further in development on this specific router, and I believe the MR7500 from the forum posts. If BS can figure out the wifi-wifi lag it will be almost perfect in my opinion. On the flip side, openwrt works much better on the MR5500 - I got them literally for a song so to speak - but as we know no NSS. Yup I have both, and gave up on both with the qualcomm issues. And now these routers are slow so I suspect less interest going forward. I shall see. I have more hope with DDWRT for the MR7350 as there are many using that device on that side. And obviously, since I now settled on the GL-MT6000 - it is openwrt - and this is a favorite and heavily developed by great developers.
Back to the MR7350, I am more watching DD-WRT for the next stable reports.
The biggest thing I have learned is I like and respect both projects, and each project is different depending on what router the dev’s got a hold of, and what people were able to help develop in their free time - and for all of us. I am very appreciative of the projects, and the work, and the learning - especially I went more Energy and Engineering, and not programming. Best I believe I can help is trying to answer a few things I do know, I applied for a wiki, i have not heard back yet - I was going to try to help create a toh for the MR5500, especially since that was my first de-brick.
if I install latest OpenWrt snapshot from Linksy webUI, will it brick? It seemed bricks happened when you sysupgrade from already installed OpenWrt? I'd better ask before flashing as i don't have tools to recover.
I have these dual-partitioned Linksys routers. I always keep the Linksys OS on one partition, each time I need to upgrade OpenWrt, just boot to Linksys, install openwrt****-factory.bin from there, always work.
I have alot of respect and admiration for all the developers and individuals working on their spare time to get this wonferful distribution and community going forward. It is amazing the acomplisments and how fast things are moving.
On that note, today I got the lastest SNAPSHOT, I am still reading about the partitions and schema on the Linksys devices, which I have two fo them. One being the MR7350.
If i sound like complaining on my previous post or anything like that - That is not the intent, just sharing ideas how to get this device on someting stable that can process VLAN trafic, which the stock firmware does not even support it.
I forgot to mention WOW you got a FLINT2 router for 80 dollars, that is a steal.
Flashing the lastest SNAPSHOT will not brick your device, flashing the second partition is the tricky part (for me)
