See link below for all in one RT-AC68U flashing guide:
https://slickdeals.net/f/12685621-t-mobile-wi-fi-cellspot-router-tm-ac1900-certified-pre-owned-39-99-plus-free-shipping?p=124882258#post124882258

You can flash this router to an RT-AC68U:
http://www.bayareatechpros.com/ac1900-to-ac68u/. There are few change/additions needed in the guide before the latest ASUS firmware can be flashed, though.
  • Avoid CFE 1.0.2.5 from the RT-AC68P, as the newest Asus firmwares (3.0.0.4.384.20624 and later) detect this on the TM-AC1900 and revert the mod. Instead, use CFE 1.0.2.0 US AiMesh; it was dumped from an actual RT-AC68U by user goggles99 at SNB. The CFE generator [pipeline.sh] by danielfeng has this version available.
  • Some TM-AC1900 ship with a firmware version that allows SSH access. If you get one of these, you can skip steps 5-10 of the guide. To check if you have SSH available, go to Administration > System in the router configuration interface. If your firmware permits SSH, there will be a setting to Enable SSH. If so, choose Yes, then Apply. Move on to step 11.
  • The T-Mobile certificates have to be wiped from the mtd5 partition. This can be done after all of the steps in the guide have been completed, but must be done before any newer version of ASUS firmware is flashed. As of this writing, the firmware included in the bayareatechpros guide is 3.0.0.4.376.3626, so the steps below should be performed when this version is running on your router.

Wiping T-Mobile certificates from the mtd5 partition

These instructions originally existed on SNB before that forum thread was shut down [snbforums.com]. Credit to XVortex and rdallen. After you've performed these steps, you can flash 3.0.0.4.384.21045 (and possibly newer) using the GUI.

Code:
# Backup MTD5 (dd produces identical bin)
cat /dev/mtd5 > /jffs/mtd5_backup.bin

# Copy mtd5_backup.bin from router using scp
# From host: scp [email protected]:/jffs/mtd5_backup.bin ./

# Mount MTD5
mkdir /tmp/asus_jffs
mount -t jffs2 /dev/mtdblock5 /tmp/asus_jffs

# Copy mtd5 files from router using scp
# From host: scp [email protected]:/tmp/asus_jffs/* ./

# Wipe mtd5 files and reboot
rm -rf /tmp/asus_jffs/*
sync && umount /tmp/asus_jffs
rm -rf /jffs/.sys/RT-AC68U
nvram unset fw_check && nvram commit && reboot
-----

ASUS RT-AC68U firmware downloads [asus.com]

SNB now disallows discussion [snbforums.com] about converting TM-AC1900 to RT-AC68U with AiMesh. So, modding information may be a bit harder to come by going forward. Some discussion has moved to this thread [whirlpool.net.au] on whirlpool.

I bought three of these. I converted them all to AiMesh ac68u models.
They are all on the latest 3/29/2019 Asus firmware.

I kind of regret it.

One single router covers my whole 4000sq ft house.

When you include an additional router as AiMesh, if devices like Chromecast connect to that node, but your phone/device is on a different node, Plex, etc. can't see the Chromecast device on the other node, therefore it can't cast to it.

It's just less hassle/complexity for my home setup to use one single router.
I use this https://www.bayareatechpros.com/ac1900-to-ac68u/ on 5 routers already.

Opening in an Incognito window, and while it shows being in stock, whenever I click "Add to Cart," I'm taken to a "Let's Start Shopping" page without anything shown in my cart. Thoughts?

I have had this for 2 years with tomato running on it. Switched my cell service to t-mobile last week and realized that this router blocks t-mobile site and apps. Have to use vpn to get through. Any ideas why and how to fix it?

you should try Merlin, and see if that will fix it.

Been having the same issues the last three times I saw this deal. From incognito and typing in my payment information(auto populating didn't work for some) I keep getting a payment information error with my VISA. I tried a bank credit card and it went through, got a processing email, but it never processed. I never received a phone call to confirm information. I tried an American Express card this time and got the processing email. hopefully it finally processes.

I've been wondering about AiMesh. That is good to know. I have two of these on opposite ends of the house connected with an ethernet cable on the local switch ports and turned off DHCP on one. Each is broadcasting different 2.4GHz and 5GHz channels. Roaming is working great and all devices are on the same network.
