How to flash TM-AC1900 to RT-AC68U:
Install WinSCP, Putty, and a file archiver (click this link to download all 3 [ninite.com]). Install the Asus Restore Utility [asus.com], mirror [filedropper.com].
Connect your computer to the *yellow* port on the router by way of an Ethernet (LAN) cable
Check if SSH can be enabled - if so, enable it and jump to step #15
Go to Administration > System > Enable SSH > Yes > Apply
Ezlink: http://192.168.29.1/Advanced_System
Create a folder on your desktop, name it "router".
Download this file [mega.nz] and extract it to the newly made router folder. It contains a firmware to downgrade to, a firmware to upgrade to, and mtd-write.
Download firmware version 3.0.0.4.384.20308 from here [softpedia.com] and unzip the file
Disconnect the cellspot router from the internet if you haven't already
Set static IP for PC.

b. Power off router (keep holding reset)
c. Wait 10 seconds, keep holding reset

Open Putty and WinSCP and connect them to 192.168.29.1 using a admin:admin or admin:password
Tip: In WinSCP select SCP as file protocol, in Putty SSH
In Putty type:
cat /dev/mtd0 > original_cfe.bin
In WinSCP refresh the window on the right side and note that original_cfe.bin is present
Copy original_cfe.bin to a local drive
Download the new .bin

username:/password is now: admin:admin
If router isn't showing RT-AC68U, try Chrome Incognito Mode
Enable SSH (see #14) Ezlink: http://192.168.1.1/Advanced_System
Reconnect Putty (see #15)
In Putty, execute the code for fixing MTD5 partition.
cat /dev/mtd5 > /jffs/mtd5_backup.bin
mkdir /tmp/asus_jffs
mount -t jffs2 /dev/mtdblock5 /tmp/asus_jffs
rm -rf /tmp/asus_jffs/*
sync && umount /tmp/asus_jffs
ln -s /sbin/rc mtd-erase
In the router page, go to Administration > Firmware and upload RT-AC68U_3.0.0.4_384_20308-gead790e.trx
This is the file you downloaded in step #6
Perform NVRAM Reset (see #24)
Enable SSH (see #14) Ezlink: http://192.168.1.1/Advanced_System
When going back into the router at this point, it may prompt you to update the username/password, not allowing you to go directly to enable ssh
Make sure you don't forget what you change the username/password to
Reconnect Putty (see #15)
In Putty, execute the code for fixing MTD5 partition.
mkdir /tmp/asus_jffs
mount -t jffs2 /dev/mtdblock5 /tmp/asus_jffs
rm -rf /tmp/asus_jffs/*
sync && umount /tmp/asus_jffs
ln -s /sbin/rc mtd-erase
./mtd-erase -d asus
rm -rf /jffs/.sys/RT-AC68U
nvram unset fw_check && nvram commit && reboot
You now can (and should) flash an updated firmware, such as Asus, Merlin, Advanced Tomato, Tomato, and DD-WRT firmwares.
To flash newer Asus firmwares at this point, go to the router page, go to Administration > Firmware and upload the latest firmware from this page [asus.com].
At this point, for security purposes I'd recommend to either disable SSH or change it to 'LAN only". Also, definitely change both the default login id and password.
Additional Notes:
Yes, step 34 is partially redundant, but this is the way I did it twice and it caused no issues.
If you complete all the steps successfully, but you plug in the router to your network and there is no internet, your cable/fiber modem may coincidentally be on the same default IP as the router is. To fix this, go to the router webUI and on the status page you'll see an error stating an IP conflict which you can click so the router will change itself to a different IP
if you want to set up AiMesh, follow these steps
Feel free to message me if you get stuck, I may not respond immediately but I will try to help
It does not connect to the Tmobile network, and does not require Tmobile service. It will not give you internet if you don't have an ISP. It is just a regular modem, but branded.
Good luck with the conversion - it's not easy but it isn't rocket surgery! (Didya see what I did there?)

I know a guy in Chicago wants to get rid of 2, One guy in the North West wants to get rid of one.
Mention your location.
Also, offerup com has listings for them.
With both offerup and craigs, you have no guarantee to get your cash back.
Advice, plug in the router at the location of meet-up (starbucks) to see if it has issues:
Look for signs something is out of the ordinary.
After reset NVRAM (Holding WPS while powering on, until power light flashes - then let go WPS) The router should boot up in a normal state.
Note: Current ASUS RT-AC68U firmware takes about 3 minutes to boot up and in that process the power light is solid, ~2 - 2:15 minutes, the WiFi lights come on,go off,then on (about ~15 seconds), then ~ 30 seconds the power light blinks 3 times then stays solid. ~3 minutes total for full boot up. Both power and the WiFi's lights stay solid.
Tmo's boot up faster. Nothing plugged in but the power cord, the power light should not flash after this " boot up ".
Reports of bricked routers had issues after "boot up " : power lights flash slow/fast and or router restarts in a boot loop.
You readers can check the pattern of Boot Up and report it in a comment below if you wish !
But that is what to look for on a router when buying used. Any flashing lights or weird behavior.
This time around, i got a pending charge but I'm still waiting for an order confirmation/number.
I ordered on the 24th and got it the 25th and received an email on the 26th saying it was delivered and they charged my CC for it, strange. Like another poster said they must have a warehouse near SW Ohio.

./mtd-erase -d asus
I pressed ctrl+c and proceededed with next steps.
Also ,I applied latest firmware from Asus's website, "RT-AC68U_3.0.0.4_384_45149-g467037b" and all works fine if it helps anyone here.
