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.
start > run > ncpa.cpl > double click Ethernet > properties > IPV4 >
IP: 192.168.29.5
Subnet: Default (255.255.255.0)
Gateway: 192.168.29.1
Place router into Recovery/Restore mode
a. Hold reset button 10 seconds
b. Power off router (keep holding reset)
c. Wait 10 seconds, keep holding reset
d. Power on router holding reset for 10 more seconds
Go to 192.168.29.1 in a web browser - you should see ASUSTek CFE miniWeb Server
If Mini-CFE webpage won't load, try Chrome Incognito mode, else use Asus Restore Utility (linked in #1)
If having trouble with this step perform NVRAM Reset (see #24) and try #9 again
Flash TM-AC1900_3.0.0.4_376_1703-g0ffdbba.trx from the "router" folder you created (hit the choose button, select the file, hit upload)
Wait for reboot at least 5 mins – WiFi lights on router will turn on when boot is complete
Log in to router (admin:password)
Go to Administration > System > Enable SSH > Yes > Apply
Ezlink: http://192.168.29.1/Advanced_System
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
a. Upload original_cfe.bin to http://cfeditor.pipeli
b. Select 1.0.2.0 US AiMesh as Source CFE for Asus/Merlin builds, (1.0.2.5 recommended for DD-WRT or Tomato)
c. Click Download
Rename the new .bin file to "new_cfe.bin"
Through WinSCP, Upload new_cfe.bin & mtd-write & FW_RT_AC68U_30043763626.trx to router
In Putty type:
chmod u+x mtd-write
./mtd-write new_cfe.bin boot
mtd-write2 FW_RT_AC68U_30043763626.trx linux
Wait until the CRC OK message comes up
Perform NVRAM Reset
a. Power off router
b. Wait 10 seconds
c. Press and hold WPS button
d. Power up the router and continue to hold WPS button for 15-20 seconds until power LED starts blinking very quickly.
e. wait 5 minutes
Reset PC IP back to default
Log in to router using 192.168.1.1 and the router is now an RT-AC68U with 64MB jffs
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 think you're possibly thinking of a different device. This actually allows the wifi calling. There are many instances in this thread verifying the same.
Prioritizing VOIP packets makes no sense. The bandwidth needed is so tiny that it would be pointless.
https://support.t-mobile.com/docs/DOC-24269
or
https://support.t-mobile.com/docs/DOC-36766
These will convert the LTE signal into WIFI so that for the phones that does NOT support WIFI calling can use your local WIFI to call/text through this devices.
This particular item we are speaking of, unfortunately confusing due to the name "cell spot router" does not have capability of converting LTE signals into WIFI signals or vice versa to enable the phones without WIFI calling feature to be able to call/text via your wifi signals.
QOS for VOIP packages becomes important when you saturate the bandwidth of the router. For example, if you are streaming multiple 4k videos, then you may be using close to maximum bandwidth, without QOS, there is chance that you will get garbled calls or even dropped calls and VOIP packet QOS will ensure clear signal. Of course, that is what manufacturers will say, as to effectiveness of it on this router, I don't know as I never really used stock firmware.
I have the ASUS AC68U. last year I was going to get an offer like this one but found a super good deal on the AC68U and couldn't justify the work to flash one for the first time compared to the deal on the actual AC68U. Now I have been looking for a repeater or extender for my garage. I was thinking I should get another and Mesh since that was my original intention and knowing that out of the box the T-mobile doesn't Mesh on its firmware again looking at flashing one.
Assuming no way to mesh since it doesn't Aimesh without flashing but wondering if it could be a wifi extender on my original AC68U until I flash it.
I found thus online looks like it might simplify things if you have an existing AC68U.
http://mutt.com/aimesh-on-a-t-mobile-ac-1900/
Also wondering what other people have used as a cheap Aimesh and or Wi-Fi extender with their AC68U other than the T-Mobile (that I am probably getting for that purpose) .

I have an original ac68U as the Master and a flashed ac1900 as the node. AIMesh is working flawlessly for me.
Make sure you wipe T-mobile certificates from the mtd5 partition, flash 3.0.0.4.384.21045 and then update both routers to the newest firmware.
Then you reset both routers to default settings and then configure AImesh.
Getting near gig throughput wired and about 250 Mbps wireless seamlessly throughout my home on my iPhone7.
I have the master linked to Gigabit fiber and the node plugged in wireless in the basement.
