TL-MR6400 V5.3 – Return to original installed firmware.
Hello,
I have stupidly updated the stock firmware of my TL-MR6400 V5.3 to the one I found in https://www.tp-link.com/uk/support/download/tl-mr6400/v5.30/#Firmware ( TL-MR6400(EU)_V5.30_230418), which is not my region ? . I bought my router from Georgia. After updating, the router's web interface does present an error while searching for bands, networks as well as, while switching network mode to 4G only (please see attached images).
See the serial number of the router and other information (I don't have the packing box anymore)
It was working fine before, after I did the update it has a problem.
I put several operator sims in the router, but the problem is still there, The problem is that it does not recognize the SIM card.
I am waiting for your help.
Best regards,
otar orbelashvili
