I can't upgrade my Archer MR600 V3 firmware and ISP error 71211
I purchased this product online from the Tp-Link Official Store in the Philippines.
While attempting to upgrade the modem, I encountered an error after selecting the ".bin" file:
"Error Code: 71211 Uploading the updated file failed. Please select the correct file."
I have downloaded all the files provided at the following URL: https://www.tp-link.com/ph/support/download/archer-mr600/#Firmware
Additionally, I attempted a modem reset, but it was unsuccessful. Could you please provide guidance on resolving this issue?
Thank you.
MODEM:
Firmware Version: 1.1.0 0.9.1 v0001.0 Build 220727 Rel.74013n
Hardware Version: Archer MR600 v3 00000002
