Big complaint is not getting into proper recovery mode.

  • 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.
Try the instructions found here:

Hi all, I've just solved the issue finally. The main problem I was having was the Asus Firmware Restoration Tool was not allowing me to return to an Asus Firmware. This is what I did it make it work.
  1. Power off the router with the power button on the back.
  2. Click and hold the WPS button located on the right sight side of the router.
  3. Power on the router while continuing to hold the WPS button.
  4. Watch the power LED light, it will begin to flash.
  5. Release the WPS button.
  6. Power off the router.
  7. Press and hold the reset button on the back of the router.
  8. Power on the router while continuing to hold the reset button.
  9. This will enable emergency mode.
  10. Open Asus Firmware Restoration Tool.
  11. Upload Firmware and your done.
My problem was I was never able to successfully upload the firmware usuing the Restoration Tool. It would interrupt and never work. But Step 3 to Step 6 made it work!

OR

Boot into Recovery Mode.
  • Set you computer IP 192.168.1.2/255.255.255.0
  • When router is off, keep holding reset button down and turn on your device.
  • When power light slowly starts to blink try to connect via 192.168.1.1 (use wired connection).
  • First select option to Restore/Clean NVRAM, then select Reboot.
  • Let it fully boot up (could take couple of minutes) and then turn it off again.
  • Now boot into recovery mode again using same method as before (hold down reset while powering on)
  • Download OEM firmware from Asus site: http://dlcdnet.asus.com/pub/ASUS/wireless/RT-AC68U/FW_RT_AC68U_90043802695.zip
  • On recovery page (192.168.1.1) select downloaded firmware file and click "Upload"
  • Patiently wait until upgrade process is complete and router fully reboots.

From the other router posts at, like here

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 admin@192.168.1.1:/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 admin@192.168.1.1:/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.

Other Tips:

If you are having problems accessing the mini-CFE webserver this works:
  1. Power off the router using the power button
  2. Set your PC's IP to 192.168.29.2 (assuming the recovery mode is gateway is 192.168.29.1)
  3. Navigate to 192.168.29.1 using your browser -- the browser continue to try and access the page until it is available
  4. Press and hold the reset button while powering-on the router
  5. When the mini-CFE webpage appears on the browser, release the reset button
  6. As long as the browser status is still spinning -- looking for a webpage -- the mini CFE web page will load

jsfitz54 what do you think i should try?
Start with the first one (example) and work through the list. Pay attention to the first bullet point... (are you sure about no SSH option?)

SSH refused connection.
What do mean refused connection. You click on the SSH box and hit APPLY on the bottom of the screen.

Gosh, it almost hurt reading this. Someone asking for help and someone just feeding information without reading, or understanding the replies.
What you are going to have to do is use the USB Instruction on this page;
https://docs.google.com/document/d/1NsZMONmJ70zMmoAKKQJXbTVKytaPJptWTpqih1TD5n8/edit

The new firmware works really hard to keep you from upgrading the router to the RT-AC68U, even though it is the same hardware.

Make sure that after you upgrade, that you go back to this page;
https://www.bayareatechpros.com/ac1900-to-ac68u/
and follow the instructions at the bottom of the page to remove the lock stuff in the MTD5 partition.

I have worked on mine for 8 hours today and there is no way to get the "Enable SSH" to happen in the newer firmware.

Good Luck

Oh, this page may also be helpful;
