If I had to write a full up-to-date guide, it would be this:
(Up to date as of 5/2/19 with suggestions in this and later threads)
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_Content.asp
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_Content.asp
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.pipeline.sh/
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_Content.asp
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_Content.asp
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

No, it is something Tmobile would issue to customers who had bad reception in their home. This doesn't broadcast mobile wireless signal, just regular wifi. Since TMobile uses wifi calling the idea is stronger wifi in your house will alleviate their weak network.

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.

Seems you're mixing your metaphors. You "pulled the trigger", not the plug. And you have to jump through hoops, not over them. You jump over hurdles.

Good luck with the conversion - it's not easy but it isn't rocket surgery! (Didya see what I did there?)

I don't know - have never touched a mac since they were still called Macintosh (1980's). I think I've seen a reference to someone doing it. Just requires a web browser and some way to log-in to ssh (terminal emulator).

I used a Mac to do it. Followed these instructions: https://lazymocha.com/blog/2018/0...t-ac68u-p/

Additional notes:
- Use "ssh -oKexAlgorithms=+diffie-hellman-group1-sha1` instead of just "ssh"
- Ignore "Bus error" at step 19 (mtd-write2)

I used the ssh that comes with Mac, which is why I needed to add extra options. The link may be the same I was just too lazy to check, I just copy pasted it from my notes, sorry. Smilie

I have couple of questions and would appreciate the inputs.
1. Can I use this in conjunction with Google WiFi system to cover 3000 square feet?
2. If number 1 is possible then should I downgrade and get the original firmware?

I don't know #1. Please expand on what you mean in #2. What firmware is currently installed. I would think "original firmware" would mean the firmware from TMobile. Never even consider doing that. It would be a huge step backwards. TM firmware is old and does not have recent security patches or bug fixes. It also has a reduced set of features.

Thanks for your response. My TM-AC1900 firmware is 3.0.0.4.376_3221. Should I follow steps to make this AC68u?

Of course. Why not turn a $40 router into a $150 one with more security, features, and continued updates. You currently get no support from TMobile or ASUS, so there's no reason to worry about voiding the warranty. Since yours hasn't been automatically "updated" to 376.3199, it is likely you should have no big problems doing the conversion following the wiki instructions. But there is a learning curve if you aren't familiar with Linux or the tools (putty, winscp).

Does anyone have an issue with the cpu and wifi chip temperature going very high? Mine goes very high so I kept a fan behind it, but the fan noise is getting annoying. I just tried removing the fan and after about 30min, the CPU temp went from 68 to 78 celsius. At the same time, 2.4 chip went from 48 to 58 and 5 chip went from 54 to 63. It was still going up so I put the fan back on. With the fan on, CPU stays below 71, but without the fan it once went up to 80.

On the other hand the temperatures on my RT-AC86U stay consistently at around 75/46/53 without any fan.

I have been running 3.0.0.4.384.20648 for quite some time. Recently, it seems to loose 1/2 the download speed even after a reboot. I was wondering if anyone is running a later version of the firmware and fixed this issue by doing so?

Thanks - Zee

Looks like there is a high chance of getting a pre-owned unit with thermal issues than a brand new unit. Having a small fan at the back of these units is a must.
