Error code: 71211
Hello everyone! I want to upgrade the firmware for my MR6400 EU v5, but I got this error. Unzip the archive, upload the bin file, but this error is present. I can not upgrade from 1.0.0 0.9.1 to 1.3.0.0.9.1. I tried even the second firmware (1.1.0.0.9.1), but the error persists. Can you help me?
