Hi,

 

The firmware download webpage for the C60 V3 doesn't mention anything about the downgrade not being possible.

So you should be able to downgrade the firmware to the old version.

sorry to mention it is US version. I couldn't find the firmware.

For some router models the region of the firmware doesn't actually matter. Although, I am not sure about the Archer C60 V3.

 

I see the local webpage for Argentina has an older "US" version available. Do you still remember the number of the firmware version you had before you upgraded?

I don't remember firmware version.

I also tried argentine version and it didn't work.( the file type was invalid)

  @RAGIB96 

 

There is no Argentine version. Most countries around the world use either the "US" version or the "EU" version of the firmware. Very few countries receive their own firmware versions.

 

The file you tried to upload to your C60 was the "Archer C60(US)_V3_190524.bin" file that you extracted from the downloaded *.zip file, right?

 

I wonder if the space inside the filename could be problematic, as TP-Link's firmware files usually don't have spaces in their name. Can you perhaps rename the file "Archer C60(US)_V3_190524.bin" to something simpler, like "c60firmware.bin"  and then try again?

I renamed the file and tried again. It still showed invalid file type.

I think the upgraded firmware won't allow downgrade,
