5530 fica abrindo aplicativos abertos direto

Tô com um 5530 que estava com o problema de desligar ao fazer ou receber chamada...

Fiz a atualização pelo Nokia Updater para a versão mais nova (32.0.007).

Então fiz o reparo que tem aqui no fórum de isolar o flex.

Só que agora o celular insiste em ficar abrindo a "janela" que mostra os aplicativos abertos.

Já resetei, troquei o touch, tirei o isolador do flex, mas o problema persiste.

Tentei fazer um downgrade com a mx key ou cyclone, mas sem sucesso.

RANGE CHECK ERROR

Pelo que vi, não é possível fazer downgrade com essas ferraemntas, somente com a ATF? Estou correto?

Poderiam me ajudar na solução desse bucho!!!

Obrigado aos amigos
