AC1200 Hardware V2 gives error 4503 when upgrading firmware
2020-08-10 23:29:14
Model: Archer C50
Hardware Version: V2
Firmware Version: 0.8.0 0.2 v005c.1 Build 160612 Rel.64064n

Trying to update firmware to current version, downloaded from TP LInk support page.  Getting error 4503: The uploaded file was not accepted by the device.

 

We've tried rebooting, factory reset, still get the same error.

 

Any thoughts are appreciated.

What is the firmware file that you tried to upload?

 

If you look at the sticker label of your router, what is the country code that is on there? Would be something like (US) or UK) etc.

We're trying to use the US version, which matches our hardware.  I don't have the full file name in front of me, but it is the current .bin, downloaded from TP Link support.

Try downloading the firmware one more time here: https://static.tp-link.com/Archer_C50(US)_V2_160801_1472173209786e.zip

 

That is for the Archer C50 v2 (US) region.

 

Before doing the update, the factory default the router by holding the reset for 15 seconds. Then connect a computer to the router with an Ethernet cable, and log in.

 

Try to upload the .bin file again, if you still get the same error, use a different web browser. If that still fails, use another computer if possible.
