Ugh, mine won't accept the BrainSlayer firmware, neither via GUI nor via CFE recovery webserver.
Over CFE, I get: The file transferred is not a valid firmware image.
The stock firmware identifies itself as: 3.0.0.4.376_2827-g566ef60
Any hints? Maybe I can downgrade the firmware to something more "accepting" of the dd-wrt firmware, but I am not sure where to get an earlier version of the stock firmware from. Hmmm.
Version 2827 is firmware locked to only TMobile branded firmwares. Not only is the firmware locked (disabled Telnet), it installs CFE 2.1.2.2, which locks the router from any non TMobile branded firmware via recovery mode and GUI mode. The only way to change firmwares is to downgrade to an older TMobile firmware (1703 for example), enable Telnet, and then replace the CFE (preferrably with an Asus RT-AC68U version - such as 1.0.2.0).
Many details in this guide including links to the older 1703 firmware and all CFE's and utilities needed:
Oh, and if you're on CFE 2.1.2.1, which is not locked, and try to use the latest Asus branded firmwares, it will update your CFE to TMobile's CFE 2.1.2.1, therefore lockout out all non TMobile firmware's again. Once you get to DD-WRT, doesn't matter anymore unless you decide to go (back) to Asus stock RT-AC68U firmware, latest copies.

Thanks, this helped a lot! I was able to downgrade, replace the CFE, then patch the dd-wrt firmwares (not sure if I had to patch the trx one first, then the latest bin. Who knows.
At any rate, seems to run nicely! I'll give it some more testing on a wired connection, but on wifi I appear to be getting a solid 100/77 Mbit. Nice piece of hardware!
Whats sad is... ps4 on wired connection still seems to get shitty download and upload ratios.. anyone else find a great way to have those higher? _________________ ~Battlez-avec la Mystique?~
Asus AC68U/AC1900 (Tmobile) - Firmware: DD-WRT v3.0-r39960M kongac (06/08/19)
I got mine many moons ago and there seems to be some CFE changes that where made to the newer versions. Some in the thread talk that they are still upgradable if you dont hook them to the internet before the upgrade. But I cant confirm that. Perhaps someone with a unit from the last few months can offer more info. Make sure you read through the thread and I believe there is also another thread that this was talked about. _________________ EA-6900

So I actually already have dd-wrt on mines but need to return this router back to tmobile. Anyone can guide me through how to bring this back to stock firmware?

I am not sure you have to. If they don't reflash the devices they get back before handing them to another customer, then they are being grossly negligent.

I'm just afraid they'll end up charging me for messing with the device firmware...since technically we're leasing this from them and don't own it

If you didn't update the CFE, just load the latest version of the standard RT-AC68 firmware. Start the router up with the Asus firmware running, and it should immediately tell you there's a new version of firmware - when you download and install it, you should be back running the T-Mobile version of the firmware.
On the other hand, if you did change the CFE, you have to apply the original CFE back, and then follow the above procedure.
Posted: Thu Apr 30, 2015 19:07 Post subject: what did i screw up
out of box i downgraded firmware to 1703 by putting router in rescue mode, changed cfe to 1020, but then it wouldnt let me flash any trx in rescue mode again, so i flashed 2121 cfe, unfortunately right after that it got automatically upgraded to latest tmo firmware 3.0.0.4.376.3002, now I cant get TELNET access at all, i tried rescue mode but it wouldnt downgrade anymore (nor would it let me flash any other trx) i tried the HTML edit solution to get telnet access but that didnt work either. am i totally locked out of editing with 3002 firmware? can any1 help?
i guess you would also have to define speed it up as thats a bit fuzzy. 10mb is fast to someone on 1mb and 200 mb is slow to someone on gig. generally you should expect 200+ mb across this device. i have much loaded into mine and it also handles my 150 at line right without issue. _________________ EA-6900

Agreed. As I understand changing firmware: especially leaping from software lines: AsusWRT to DD-WRT invariably slows performance, but increase functional capability. The reason that I use AsusWRT Merlin on my TMO router is not to speed it up, but to maintain stock speed and add capability. As I understand, stock speed is generally the upper limit. If this is not right, I'd like to know. _________________ My Routers | RT-N16 Wiki | TMO Cellspot Wiki Peacock Flashing | Wireless N Conf | Linking Routers |
