Kevin_Z thank you for the feedback!

Initially I had the version 1.0.2.

Then I tried version 1.1.0 and got the message "This operation is not allowed for remote management."

Then I tried version 1.0.1 and it was successfully installed. So I tried version 1.0.2 success again, but then 1.1.0 gave me the error message 

So my current vesion is the 1.0.2

All files I took from this page https://www.tp-link.com/en/support/download/archer-c6/#Firmware 

All attempts I did using my laptop connected by the wifi, then I tried PC connected by wire, the same error appear. And I didn't find any other methods how to update firmware thn open the local router's page and upload firmware binary file.

Dear Kevin_Z!

As you asked, I connected my PC using wired cable, then logged in using your instruction, then followed to advanced-system tools-firmware upgrade and then uploaded binary file, but still no luck, I'm still getting the error message.

Actually I did this before with the same result...

The binary file that fails is ArcherC6v2_eu-up-ver1-1-0-P1[20190115-rel71848].bin (I think this name contains all information that you've requested.)

I was able to install the following previous versions of the firmware:

ArcherC6v2_eu-up-ver1-0-2-P1[20180810-rel36826].bin - this is current version of the firmawart on my router.

ArcherC6v2_eu-up-ver1-0-1-P1[20180627-rel42764].bin

Thank you very much, I'll wait.

@Kevin_Z 

I wounder why you didn't continue the dialuge in this thread; as many will face the same issue. I personaly have the same problem and I failed to update the firmeware despite the many attempts.

could you please continue within the forum.

Best Reg.

Hi,

Please wait a while until they reach out to you.

 

Thanks for your understanding and cooperation in advance, and have a nice day.

Hello and thank you for your reply. With my case, the problem was the hardware version/region. I had to escalate in order to get the correct firmware. After getting the correct one, the upgrade went smooth.

Two points I would like to highlight: why it is defecult to search and find the correct firmware. Even when you try to check for update from within the router management page, you get misleading message.

The 2nd point, why the message I got during the upgrade process is misleading? It says "the operation is not allowed for remote management". It should have been "wrong firmware version" or something like that.

@Vetal The same happened to me. The problem was that I was trying to update with the wrong firmware version and the message that appeared was wrong too, once I was not trying to update remotely.Here in Brazil some Acher C60 was sold with UE version. Mine is UE version and I bought it in an official store. So here in Brazil we have the brazilian version and the UE version. Check the right version in the tag at the bottom of the equipment. NOTES: After the update with UE firmware version (English version) my router came with a language that seems to be from Russia. I believe my router is a Frankstein (UE version, sold in the brazilian market with a firmware adapted by TPLINK).
