Hi Kevin.
Thank you very much again for answering me.
I was finally able to solve the problem.
Obviously the problem was with the pendrive. I had updated it with an 8 Gb pendrive. The light sequence made it as it should do to update, but it did not update.
I got a very old 2 Gb pendrive, and I did the process. It was perfect, now it connects, and it reconnects without problems.
Hope this works for users of this bar.
Thanks a lot again Kevin.
Greetings to all
