Not able to upgrade from 376.49_2 to 376.49_5

[ychauhan4u]

I have Asus TM-AC1900 Router with Firmware: 376.49_2.
When i tried to upgrade to 376.49_4 or 376.49_5, i am getting Error Message.
I never had such issue in past while upgrading to new Merlin firmware.
Is anyone with Asus TM-AC1900 Router able to upgrade to 376.49_5?

First, make sure you have the correct version for your router (RT-AC68U).

Second, remove all USB cables, printers and other devices plugged in except for the computer that you will be doing the upgrade from.

Third, reboot the router and wait a good five minutes before you try to flash the newest firmware.

You're stuck with it unless you change the CFE with one from regular AC68.
See the CFE thread
