cannot flash with RT-AX86U_386.4_0

[karmic913]

Hi

I have just installed my new RT-AX86U and upgraded it with latest stock firmware 3.0.0.4.386_45934

rebooted

Attempted to flash it with lastest Asus-Merlin RT-AX86U_386.4_0, but I get this error message:

"asus merlin "Firmware upgrade unsuccessful. This might result from incorrect image or error transmission""

Any idea?

THank you!

Welcome to the forum!

Not confusing AX68U with AX86U maybe?

 

[karmic913]

good thinking - I wish!

Another one did you validate the update point to the firmware and not the zip file.

I’m not sure I get that - can you elaborate?

It comes in a .zip container. You havet to extract the image out of that container.
Right click on the file and choose extract here

Oh yes - I did that, thank you.

The file I end up selecting for upload is named
RT-AX86U_386.4_0_cferom_pureubi.w

Sounds about right

Nuclear reset and try again

Did you check the SHA256 checksum of the file? That should tell you if you have a corrupt file or some other issue.

 

[JGrana]

The AX86U is local correct? Your not trying to update a remote AX86U?
The reason I ask is that I have been unsuccessful in upgrading a remote AX86U multiple times, OpenVPN off/on, reboot, disable jffs scripts, 3 different browsers, downloaded the .w file from both Sourceforge and OneDrive, etc…

BTW, is there a way to upgrade using CLI/ssh?

 

[karmic913]

I do it locally - thanks

Post a picture of back side label of this AX86U, please.

 

[JGrana]

Not to take this thread too far off topic.
I see an hnd-write on the remote AX86U. From what I have read, it is the HND replacemeant for mtd-write2.
Anyone ever use it to flash a local copy of the .w file on an AX86U?
If so, successful? What was the command line?

Yes, I get a match on the SHA256 signature - thanks

Thanks for your inputs

Prior to reading your reply, I opted to reset the router to factory settings, and flashing with Merlin worked after that. I guess I had too many custom settings in place already.

What you did was easier in the long run, just a plain router reset.
You should have done a second Reset after the flash to Merlin, then after the reboot then apply your settings.

The method I outlined is for more serious, nothing works, issues. I've done it quite a number of times.

Glad you got past your problem.
