Re: Accidentally CHANGE USA BAND, PLEASE HELP ME.

Dear, I also invited the same problem with my M2 Dual (D2302). Approached Sony Service Centre and on there advice changed the Mother Board. I Know Costly the Repair. But since i like that phone very much i have to go for it. Other internet ideas and solutions never work with this Sony Xperia. So, if you want to get your mobile back in to working condition then approach Sony Service Centre Please.
