TM-AC1900 Flash Back to Stock

[J.T.]

Hi, can someone tell me how to flash my TM-AC1900 back to stock T-Mobile firmware. I flashed the Asus firmware on it last year, but I would like to now revert back. Can someone point me in the right direction?

I am in the same situation and have not found anyone that has documented how to do the revision. However, I would like to put out for discussion that using guide at

http://www.bayareatechpros.com/ac1900-to-ac68u/

to flash back the original original CFE bin file and then use the mini-CFE to install the 1703 T-mobile firmware and then hook the router to the internet and allow it to update might work?

Does that seem reasonable?

Why revert?
If you want to revert, seem like you would flash the original cfe you were supposed to save and then flash the t-mobile firmware.

I am guessing the original poster is planning to return the router to T-Mobile. They might charge if something other than the T-Mobile firmware is present.

Exactly. I upgraded to the AC86U and will just return the T-Mobile router.
