Tags: #Firmware Update #Error code: 4503
Model: General Product  
Hardware Version: V1
Firmware Version: 1.1.0 0.9.1 v700c.0 Build 200420 Rel.41047n


I've been trying to upgrade locally my router Archer RM600(EU) from 2 websites :

https://www.tp-link.com/en/support/download/archer-mr600/v1/#Firmware and https://www.tp-link.com/fr/support/download/archer-mr600/v1/#Firmware

(apparently this model is not on the us website)


There are 3 firmwares available :

  1. Archer MR600(EU)_V1_210608

    Published Date: 2021-06-10 Language: English

    File Size: 10.75 MB

  2. Archer MR600(EU)_V1_200511

    Published Date: 2020-06-28 Language: English File Size: 10.73 MB
  3. Archer MR600(EU)_V1_190412

    Published Date: 2019-05-24 Language: English File Size: 67.84 MB


NONE OF THEM WORKED!! (obviously I made sure to extract the zip and used the .bin file as mentioned in the pdf tutorial: How to upgrade TP-Link Wireless 3G4G Router)


I always make sure the version was right before I download the firmware.


Here are the errors I receive:

For the 2 most recent firmware : Error code: 4503 The uploaded file was not accepted.

For the last oldest firmware : Error code: 71211 Failed to upload upgrade file. Please select the correct file.


PS: The User Interface is branded with my network provider's logo

PPS: Forgive me for putting General product in the model section I could not find my tp link router model (which is quite strange for me)

Hi, may I know the hardware and firmware version of your Archer MR600? and who is your network provider?

Since you mentioned that the user interface is branded with your network provider's logo, it is likely to be a customized firmware for your network provider, that is also why you are unable to upgrade other common firmware.


By the way, is this MR600 provided by your network provider?
