RT-AC68U V3 Merlin Supported?

[RMerlin]

Can this be used to (eventually) get RT-AC68U_384.17/18/19_0 on a V3 ?

No. Asus put in place the version check because earlier firmwares did not support the V3 hardware.

Im on Firmware Version:3.0.0.4.385_20630. Can I use the file you uploaded?

Yes, doesn't matter what you were previously running.

So the rt-ac68u v3 is an 1900P v3 model.

Nobody mentioned a "1900P" let alone a V3 version of it.

Need help deciding between rt-ac1900p v3 or the rt-ac68u c1

I currently have both the rt-ac1900p v3 and the rt-ac68u c1 and I need to return one. The AC1900p v3 is the only one that gives me a little bit of information about the hardware on the box and on Asus's website. It says it has a 1.4 GHz dual-core processor. Also somewhat interested in trying out...

I don’t know but Another forum says its an ac1900p v3 but it dosnt looks like it works with merlin so i think its something different. Anyone can confirm?

The latest beta 386 Beta 2 added support for V3.

That is a device from over 4 years ago. This thread is talking about a brand new device that didn't even exist 6 months ago.

I'm waiting on more info from Asus, in the mean time can you try this test build?

RT-AC68U_386.1_beta2-gf4dd1608fa.trx

TRX File

1drv.ms

I suspect I just need to update the header signature to mark the firmware as compatible with this newer revision, so I just built it with a signature matching the GPL code used in it. Make sure you download a copy of the original firmware from Asus before testing this one out, just in case.

EDIT: That should do the trick, I disassembled the code responsible for the image check, and the RT-AC68U V3 has a minimal version requirement of 385_20490. My firmware was only faking a 385_20000 version.

Thank you very much! And a rapid response too!

But to add to my original question, I have bought anouther router (RT-AC86U) that serves as the master router in an AIMesh setup. Would it still make sense to test the new build on My RT-AC68U although it acts only as an AIMesh node? If so I would be happy to do it.

Yes, the question is to whether the router will accept the firmware image or not.

 

[Jifle]

Yes, the question is to whether the router will accept the firmware image or not.

And the simple answer is... Yes, works lika a charm without a hazzle! This time the RT-AC68U v3 router accepted the new firmware to be installed and it immediately worked after the update.

Thanks a ton!

Heya,

I tried and it worked!

Thank you for quick help! This is exactly the reason why I ditched my AC87U and went for 2 AC68U to continue using your firmware.
Keep up the great work.

If any issues occur, I will def. let you know.

 

[galbert]

Thanks for your help. Has anyone tried the latest beta on this new model?

Thanks a ton!

Is it possible to see the specs of this router in merlin? What cpu this router has ^^

Can someone with the V3 model post the output of the following commands?

nvram get odmpid
nvram get model
nvram get productid
nvram get wps_modelnum
nvram get wps_device_name
nvram get boardrev
nvram get boardtype

Thanks!

Here you go. This one is set as a Node so not sure if it should output more information.

nvram get odmpid

That output is empty

Wow....that's unexpected!

Can someone with a V3 not as a node give it a try?

 

[RMerlin]

I know Asus has a shared/private.o function to detects if an RT-AC68U is a V3 model, in which case they check that you are running 385_20490 or newer. That probably means you need special support for that new revision, like the C0 revision did at the time. I don't know however if it's just for the logo (which used to be a controlable LED) or if there are other hardware-level changes.

It still shows as an RT-AC68U, which would be why there's no special odmpid for it. It's just a newer hardware revision.

 

[john9527]

@jpdsc

Can you try this command?

strings /dev/mtd0 | grep odmpid
