[Help] Asus RT-AC68U Unable to Flash Firmware

[omnigear]

I Followed the directions
power down
hold reset button , power up and hold reset for 10sec
recover mode, insert firmware , upload and it should flash

the problem is that it goes through all of that and it just comes back the same firmware as in the image.
i have tried using the Asus software to flash and it still ends up the same
i have tried using various firmware , even the stock ones from Asus , any help would be greatly appreciated

Hi,

376.x is simply far to old to update directly to the newest firmware version!

We are nowadays on 384.x firmware - so you need to do an intermediate step to change the ROM/NVRAM layout: Install Merlin's something like RT-AC68U_378.55_0 *) first and then go for an actual version.

*) I recall that you should install .50 for the CFE (BIOS) update and re-partitioning - but I could not find it in the Merlin archive - hope that .55 works as well.

I'm having the same issue. I'm on 384.5 Beta 2 and it won't upgrade to 384.5 release version. It won't upgrade. I had this issue before with an older version and I had to downgrade to an old version like 378.55 then do the upgrade to 384 beta. I think I need to do this again but go from 378.55 to a few more incremental upgrades throughout the process to get to 384.5 release version.

I shouldn't have to go through this just to upgrade firmware. I'm not sure if something is corrupted or what. I've never had this issue until recently. I've had this router for 2 or 3 years no issues.

Well beta firmwares are called "beta" for a reason. What router model do you have? Is it a TM-AC1900 because they're not supported?

Thank you, Fixed it flashed

It's a TM- AC1900 which I converted to an AC68u. Like I said I never had problems betas or release until the 384 betas. I will try to downgrade then upgrade to only the full release and see how that upgrade goes for now on. if I keep having the problem it's got to be some corruption error.

What do you recommend when upgrading? Clear the cache, nvram etc....

Thanks

Which version did you upgrade to? 384.5

It's not a corruption. It's a known issue because the TM-AC1900 is not supported anymore (it never was officially).

Dang... I did not know that. I would have thought the internals were the exact same and the firmware would act the same on tm versus Asus version
