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?)

Alex jumbled them in to the order of commands compared to the Lazymocha's Guide [lazymocha.com]
The first 7 are (Lazymocha's Guide)
The last 2 mtd5 commands were ( Bayarea and Lazymocha never explained be on firmware 384.xxxxx)
1) Are you saying the command be removed completely from the first 7 commands re: Bayareatechpros/Lazymocha's Guides from your quote above?
2) If so, are the commands correct for the firmware 376.3626 seen below, with your suggestion above?
3) Would it also be safe to say that another option of doing the Lazymocha's /Bayareatechpros Guides would be to install (376.3626),
* is needed because it will increase the partition size from 32 to 64 MB which allows you to subsequently upload any newer version.
Then, instead of doing the first 7 (now 6) mtd5 commands, just reset NVRAM and install 384.20308, reset NVRAM again..
and do all 9 (now 8) commands below?
Do the guide.
If the guide(s) say:
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
Why are you asking this question?
I'm not sure if these directions are assuming that you are connected to the internet via the router that you are flashing and nothing else.
For every step in the BayAreaTechPros guide that it says to go to 192.168.29.1, for me that would mean going to the other router that I want to leave alone instead of the one I do want to flash.
Does that make sense?

It would be safe to say, doing the Lazymocha's /Bayareatechpros Guides, the process of installing (376.3626)
* This will increase the partition size from 32 to 64 MB which allows you to subsequently upload any newer version.

My other point to him was simply that if you are going to add a step to install 384.20308, don't do any mtd5 cleanup while running 376.3626. Do it all in the 384.20308 code. And since it is a 384 release, the ability to directly erase mtd5 makes it unnecessary to run the following commands:
[Code]
cat /dev/mtd5 > /jffs/mtd5_backup.bin
ln -s /sbin/rc mtd-eras
./mtd-erase -d asus
rm -rf /jffs/.sys/RT-AC68U
nvram unset fw_check && nvram commit && reboot]/CODE]
I'm not commenting on those other instructions since I don't read or follow them. My above suggestions only apply when the instructions include a mandatory step to install 384.20308. However, if that gets people confused, maybe its better to leave out that optimization and just do the cleanup in 376.3626 and defer the mtd-erase commands until the latest firmware is installed.

OK
Use FIND on this page from the very top of this page. and find " A guide on the Internet connectivity during the process."
Do you have 1 router or 2?

Clear your browser cache. Use Google Incognito mode.
Have chrome browser set to go to 192.168.29.1.
Trick is, have browser SEARCHING for 192.168.29.1 when holding RESET when power on of the router. SOON as mini cfe opens.. quickly find and load the firmware until 10% loaded, then let go the reset button.
IF that fails
Try reading the notes Step 2 - Flash the "functional" firmware with an older T-Mobile firmware Which is pretty much the same, but using CMD to ping the router. As seen in the below notes. (ignore his 192.168.29.8 text) just use cmd.. run as admin.. type: ping -t 192.168.29.1 and you see the results are the same as his as he shows in the photos, red text is his notes what happens when he uses the mini-CFE holding reset, turning on power.. it is all in the timing.
And he uses incognito mode.
IF none of the above helps you, THEN you have to do the Google Doc. Guide
(Again, top of this page is the Community Wiki.. search for "If accessing the mini-CFE webserver doesn't work at all for you... " )

EDIT: would I just be better off having the other router as just a access point or repeater? If that's better I'll keep both at Merlin or even DD-WRT.
