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.

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

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?)

Currently, I have Merlin firmware 384.4 on this router with the CFE 1.0.2.0. This was before the new CFE came out and the also the instructions on removing the t-mobile branding.
I believe what is required here is that:
- Update to AiMesh CFE
- Create new CFE using the online CFE tool
- Do I just use the current 1.0.2.0 CFE as the source CFE on the online tool?
- Update the CFE to 1.0.2.0 AiMesh
- In Putty type: chmod u+x mtd-write
- In Putty type: ./mtd-write new_cfe.bin boot
2. Remove the t-mobile brandingcat /dev/mtd5 > /jffs/mtd5_backup.bin

3. Update to latest merlin firmware through GUI
I'm assuming I do not need to update the firmware to FW_RT_AC68U_30043763626.trx as I'm already running 384.2 firmware on merlin so the
If you follow some video guide that holds your hand through each step, then sure it could be easy. Especially if they explain how to fix any issues that arise. If you have no understanding of networking basics, this might be a weekend project.

After a while the rep said there are no more in inventory so she cannot :-(
It's terrible how you don't even get an order number...
Your summarized outline looks good to me. Just a couple of thoughts:
1. While I think it is a very good idea to update your CFE, I doubt it is absolutely necessary for Merlin. It is more to "future-proof" your router in case some future firmware looks for some tell-tale values that are only in the old 1.0.2.0 CFE. It's a red-flag that your router is not legit.
2. Since you are already running 384.x firmware, you could just run an abbreviated set of commands:Any time you change CFEs, you should erase NVRAM. Some people erase NVRAM whenever they update any firmware. I just do it:
Not to mention, if a lot of people connect to your internet, it might slow down your bandwidth.
Please correct me if I am wrong.
Sorry I missed this as I would like a second one.
