Hello, I got a model for repair, as in the topic with damaged firmware, all the time on the logo. I tried to upload the latest soft via the memory card, but error 7 pops up, I did not find a newer software than the one provided by the manufacturer. I add a screenshot after trying to upload the software, maybe someone of you had a similar case and maybe you have a firmware that works, I will add that the tests are like the hardware was ok and I also wipe it
