Ahh yes good idea, can use the "Watching First Post" option.
And in profile settings you can set it to email you when you're away
Purchased this device last Friday and today came home.
Did the process on the wiki and everything was working nice.
This weekend I will be testing this new device.

Using this

@S7venLights
Hello and thank you for this guide. I'm a new user and only entry level network engineer type (its not even my job, but I did obtain Network+). I messed up.
At Part 2 step 5:
ubiformat /dev/mtd18 -y -f /tmp/factory_image.ubi
ubiformat /dev/mtd20 -y -f /tmp/factory_image.ubi
I forgot to replace the "factory_image" with the actual name of the file.. I rebooted and the router won't load USB back up (I've tried several times). It is in purple mode and not responding to anything. What do I need to do to fix this? I tried hitting the reset button but it didn't do anything.
I tried opening the links to serial stuff, and they seem to be broken. Any idea?
Actually the links work, but hoping I don't have to go this route.
Hi Sorry to hear, I updated the instructions to highlight the need to change filenames and to set USB recovery earlier inline with the latest official wiki. I also made a few other changes to make things more understandable.
I'm no expert, so not sure how I could help for your specific issue. But can you still SSH into the router?
If so, can you redo the commands you messed up correctly?
or perhaps even restart the process form Part 1 step 4 or 5?
If that doesn't work, I'm not sure... maybe @hnyman can help?
If you did in fact get to the section that sets USB boot for recovery, make sure you have the right file/image on the USB stick. My instructions for setting USB boot at the time you installed set this as the USB recovery:
fw_setenv openwrtusb 'usb start && fatload usb 0:1 0x44000000 openwrt-ipq807x-generic-dynalink_dl-wrx36-initramfs-uImage.itb && bootm 0x44000000
According to that, you need a file called openwrt-ipq807x-generic-dynalink_dl-wrx36-initramfs-uImage.itb on your USB stick.
Maybe try renaming the intramfs file on the usb stick accordingly.

That is a great point about renaming the file. Maybe it makes more sense to just come up with a simple, fixed name for the file (ex. "Dynaboot.itb" ) when setting the USB bootcmd line. Then it's just a matter of renaming the downloaded file on the USB before recovery booting.
I'm losing my mind, already successfully followed these instructions once before but now, for whatever reason, I can't get the router to boot into the initramfs (snapshot version). The USB stick is formatted FAT32, the command I'm running is fw_setenv bootcmd 'usb start && fatload usb 0:1 0x44000000 openwrt-qualcommax-ipq807x-dynalink_dl-wrx36-initramfs-uImage.itb && bootm 0x44000000; bootipq', I've even tried copying the initramfs file from /mnt/UNTITLED to the default folder.
It just reboots into OEM firmware every single time. I followed part 1 perfectly, I have no idea what I could be doing wrong.
Too large or modern memory stick? (Although fat32)
Some sticks have got USB enumeration differently than 0:1
You might try 1:1 or 0:2
Not all USB sticks work, using an older USB2 stick seems to work better

Appreciate the swift responses everyone, I ended up going to the store to buy another USB drive. Bizarrely, the one I tried unsuccessfully was actually an old USB 2.0 stick (also plugged into a USB 2.0 slot, maybe that has something to do with it?)
The one I just bought is 32GB, USB 3.2. I simply dropped the initramfs onto it, plugged it in and it successfully booted into OpenWrt. Got everything working ok.
Is there an easy way to check the USB enumeration under Windows, for future reference?

Probably easier to do it on your router, once you got Openwrt back.

The enumeration varies by the stick type, and is naturally related to the router's OS, so Windows has no knowledge about Linux enumeration.
Example of trying three sticks in my MT6000 router:
(note "usbutils" installed for "lsusb" command, but the same info is in the system log, too.)
Old slow stick got 1:2 while new USB3 sticks got 2:1
root@router6000:~# opkg install usbutils
Installing usbutils (017-r1) to root...

Hey, I was trying to install OpenWRT and forgot to insert the USB with all the files, I used fw_setenv bootcmd command before rebooting 
The router boots with purple LED and not blue, can't access it via SSH either. I guess it's trying to boot into nothingness now. Is there something I could do before I resort to poking SERIAL port (with 0 comprehension of its mysterious interworkings as well). Any help is greatly appreciated!
Insert the USB drive....?
No workerino still
Assuming you got the params right, the only reason why it wouldn't boot, is the flash drive.
Try and older and smaller flash drive, but if it fails, serial the only way to fix it.
