That's fine, the your Win guide can be linked to from the wiki, just as the post for decrypting the backup file is.
VLANs work like a dream.

I followed your Windows guide and installed OpenWRT without issue. It also saves people from skimming through hundreds of messages to understand the process. Thanks for sharing it!

Also curious at this, but openwrt probably doesnt do anything with it. Would love for it to be on, can always use some repeaters for iot devices.
Thanks, appriciate it, just know all the work is done by the tech savy folks here.
Hi all, any help would be appreciated. I bricked my device; I did save all the commands I executed after I ssh'ed to my device running initramfs from memory:

I am pretty sure this part is the problem:
root@OpenWrt:~# fw_setenv bootcmd 'setenv bootargs console=ttyMSM0,115200n8 ubi.mtd=rootfs rootfstype=squashfs rootwait; ubi part fs; ubi read 0x44000000 kernel; bootm 0x44000000#config@rt50

I thought I could factory reset my device and that would wipe bootcmd to then boot from initramfs from my usb
but pressing and holding the reset button for 7 seconds does not wipe the bootcmd command.
Also, while I do have serial to my device, I never get the U-Boot prompt

I already ordered another device, if I recover this one this would become my test device.
'- rev0'
The extra space after '-' seems an issue.
A good start you got some outputs from serial console.
Please try swap the Transit/Receive pins.
You do not got to u-boot shell because the pressed key is not detected during boot.
I got the same issue, which after swap the pins fixed the issue.

if the Transmit/Receive pins were connected incorrectly I would not get anything on my screen
Then try another terminal program. And double check the baudrate, 8N1, etc.
Then you might have other issues. As swap pins works for me.
I doubt my problem has anything to do with "baudrate, 8N1, etc" since I am not getting any garbled text
I am just sharing my experience - as I unbricked my router using serial adaptor on Friday night.
Good luck.

Thank you very much for the link.
Will study and do some test and report back.
1st Test (easiest to me)
This is direct connect to ISP, no router
Stock Firmware
OpenWrt SNAPSHOT r21968-acd8e94d20

This router has been sold out in Europe for now it seems, but you can import it through amazon.com, and it will cost around 105 euro in total. Quite a step up from 69 euro, but still a fair price in my opinion for the hardware you're gonna get. Hopefully amazon.de will also have more stock soon.

Do we have to procedure to covert from OpenWrt back to Stock firmware somewhere?
Yes, here you have it:
It worked just fine for me using Arch Linux.
@dick902 had issues with the dumpimage version and updating to 2022.10 fixed it.

Not sure if already mentioned here:
With stock firmware, after the backup.cfg is applied to enable ssh access, ssh access is opened for both LAN and WAN .
I tried to enable Firewall in stock firmware, but I cannot make it stop ssh access from WAN .
Even changing password in GUI, the ssh password is not changed. Only the GUI password is changed.
How do i factory reset the device, keeping openwrt where possible?
I cannot connect to my third one, im not sure what i messed up, but can't ssh into it anymore, and luci also wont start on the address.
i cant imagine its bricked since i changed no critical settings. just ip settings and some radio settings.
You might read wiki:
DL-WRX36 has a reset button (pinhole), so when the router is normally up and running OpenWrt, pressing the button for 10 seconds should reset it (and revert it to 192.168.1.1 etc. defaults). (I haven't tested it so far).
Alternative is the failsafe mode, which requires you to push a button (e.g. the WPS button) during a 2 sec time window in the boot process when the led blinks more rapidly than otherwise. The should lead it to the failsafe mode, again with 192.168.1.1 (and no settings, no password)
thanks, that worked! I'm very glad, i now have all my 3 devices running in a mesh setup, providing perfect coverage everywhere in the house. Hopefully it stays stable.
