@vectorsigma the main reason for the 4503 error is the wrong region selected when downloading firmware from download centre of tplink website.

Try different regions when downloading firmware.

 

At first i had selected pk region then us so us region worked.

 

Changing of region also change the versions of the firmwares.

Hello all, this is a quite old thread, but I agree with @hijani that whenever you download and or upgrade the firmware on a TP-Link device, do remember to verify its country code and hardware version before upgrading, ensure you choose the correct firmware to install on your device.

 

Back to the initial question that some of you failed to upgrade the firmware on the TL-WR840N<W> v4.0, I guess this is special and customized hardware that was developed for the local Service Providers, so you cannot install the generic firmware on it.

 

If any of you can confirm this for others, we would appreciate that.
