(One of the few routers that supports most major 3rd party firmwares)
Process summary below:
Do not flash if you do no have the need to do so.
Yes, it is possible to 'upgrade' the firmware, but if you don't know what the 'upgrades' and extra features are for then it is all useless. This router will works fine out of the box for the average person using Stock tmobile firmware Note that there is a chance of bricking the router if you do not follow the CFE changing instructions properly.
Note: Average time to do this. First time Novice but VERY literate & Patient: 2-3hrs
Regular user with no computer comprehension: Dont even attempt and have your "geek" friend do it.
OUTLINE OF PROCESS
1) If you are running Tmobile Firmware version 3.0.0.4.376_3108 or earlier you must DOWNGRADE the firmware to T-Mobile Firmware version .1703 (to enable Telnet)
2) Extract CFE bootloader and copy/paste MAC addresses and WPS code into Retail Asus CFE. (1.0.2.0 retail is probably the best one to use)
4) Flash Asus CFE
5) Then flash your choice of firmware using Aus Restore Utility or MiniCFE webpage
-----------------------------------------------------------------------------------------------------------------
This following method works as of April 2016 and works if you are running firmware version 3.0.0.4.376_3108 or earlier. NOTE: If the Guide tells you to press or wait for 20 seconds, it means 20 seconds, not 19 not 17, not 10...it tells you to wait for 5 minutes, its a FULL 5 minutes, not 3 minutes, not 4 minutes 30 seconds, it means 5 MINUTES! If you have NO patience or time and cant follow instructions this guide is not for you.
PROCESS1: DOWNGRADING FIRMWARE TO V3.0.0.4_376.1703
0) Disconnect the router from the network/internet, only 1 wired Ethernet cable should be plugged into any LAN port, DO NOT do any firmware related flashing via WIRELESS
1) Restore FACTORY DEFAULTS of the Router, this should set the IP of the router to 192.168.29.1
2) Set your computer to use a static IP of 192.168.29.88
3) Set your router to Recovery/Restore Mode by:
Turn power off to the router by disconnecting the power cable
Wait 10 seconds
Press and Hold the Reset button
Restore power to router while continuing to hold Reset button
Continue to hold Reset button for 20 seconds then let go of the reset
4) Wait 180 seconds (for router to fully boot)
5)using the "Asus Firmware Restoration Tool" or "MiniCFE webpage" (MiniCFE webpage is using a web browser and going to the routers IP of 192.168.29.1)
6) Flash the Tmobile firmware version 3.0.0.4_376_1703 TRX file.
7) Wait 5 mins

Press and hold the WPS button
Restore power to router while continuing to hold WPS button
Continue to hold WPS button for 20 seconds then let go

10) The firmware should now be downgraded and you can verify by longing into the router and checking the firmware version through the web browser interface.
PROCESS 2: ENABLING "TELNET" AND FLASSHING "CFE":
1) Considering you are on Tmobile firmware version 1703, RESTORE FACTORY DEFAULTS
2) Login to the router using the web browser and navigate to the ADMINISTRATION > SYSTEM> ENABLE TELNET> YES (then apply and save settings)
3) Change the CFE using Engineers guide, i recommend using CFE 1.0.2.0 and MTD Write v2.

Please read though guide and post comments (both good and bad) in the thread. Thanks: Engineer

NOTE: If you are flashing later versions of Asus or Merlin 376.xxxx or ANY version of 378.xxxx or 380.xxxx (Asus or Merlin), you must flash to a firmware that will expand your rootfs partition from 32M to 64M first. Asus 376.3626 is recommended. Flash Asus 376.3626 and after installation, reset NVRAM. This will expand your rootfs partition and allow the new firmwares to install correctly!
1) Set Static ip of 192.168.29.88 for your PC if router is using tmobile firmware
(or Static IP of 192.168.1.88 if on retail asus firmware or custom firmware)

Works with ALL the tmobile TM-AC1900 cellspot routers as of 4/15/2016. it had CFE 2.1.2.2 and was downgraded and installed 1.0.2.0 The video below shows to install and change CFE and Flash firmware right out of the box https://www.youtube.com/watch?v=RI6D0LMkm3s NOTE: in this video the router enters recovery and the lights blink, HOWEVER on the newer models the router will enter recovery the same way but the LIGHTS DO NOT BLINK. As long as you unplug and then re-plug the power to router while continuing to hold WPS button for 20 seconds you should be in recovery, do not worry if the lights are not blinking.

This firmware is needed after upgrading your CFE to expand your rootfs partition from 32M to 64M. Later 376.xxxx and all 378 and 380 firmwares need this 64M rootfs partition. They will not load otherwise.

You got yours "free" on loan. If you do not return it when you terminate your service with T-Mobile, then you are paying the $249 original price..
I received mine the same way, but I tossed it when I moved. Not the best idea, since even if I purchased another at a cheaper price, the serial number does not match what they have in their system.

Tmobile should only be charging 99 plus tax not 250 that's what they charged me when I didn't return it
Got this on loan from T-mobile as well. Great router and the only issue I have is some times the 5ghz signal slows to a crawl. A reboot fixes it but can get annoying some times. Otherwise, great router with great wifi speeds.

I got mine for free from tmobile.
Obligatory copy/paste of instructions in previous post to re-flash the T-Mobile firmware to Asus (or third party). Also has link to product page.

shipping should be included to the price. I don't see a way to do store pickup. Still looking to see if there is a way to p/u at a store.
And of course, plus tax in Kalifornia.
