I have a TP-Link Archer MR200
Firmware version : 0.9.1 1.2 v004a.0 Build 180502 Rel.53881n
Hardware version : Archer MR200 v1 00000001
I try to install OpenWrt firmware directly with the current firmware.
I have the following error message :
Error code:4506
The uploaded file does not match the device's current hardware version.
I don't found this problem on the forum
Can anyone help me?
What happens if you follow the instructions in the OpenWrt wiki?

thanks for the quick reply, but alas I don't have the skills to perform such a procedure.
I'll see if I can find a video on the internet that shows all of this in more detail!

A command example is given, do some leg work, Google man dd, to understand what you're doing.
The cat command can in win be replaced by copy /b a + b c, the /b is important
