@Kevin_Z Good, finally .. it's so simple. Thanks, now it's time to test.

@Kevin_Z already did the factory reset but everything remains the same .... may it have to do with the ISP list not being updated? already tried to update but always gives error 71212

@Kevin_Z Actually the version I had was the previous one, I installed the new one but the option of choosing a band still does not appear ... Now it’s asking to update

@darant First of all thanks for the excellent work. I managed to install the update without any problems, but I don't have the option to choose the band ... In the meantime there is another...
