Hello everyone and a huge thank you!!!
I reread the entire thread and eventually realized that my head was all a mess, I've never dealt with such firmware before.
As a result, I turned to Artificial Intelligence for help, this service was especially helpful. What's great about it is that it changes LLM models itself as needed. I asked a question about how to flash my two LV07 miners. As a result, I received detailed, step-by-step instructions and a link to your correspondence. Many thanks to everyone. From your correspondence, AI answered my questions and directed me step by step how and what needs to be installed on the computer and how to flash.
As a result, I flashed both miners the first time. Cool, now I'm calm that if I'm lucky with finding a block, then the bitcoins will fall into my wallet, and not to someone else's uncle.
