water damaged iPhone isn't working after replacing and cleaning (isopr
I replaced the battery, logic board, cameras, speaker, antenna and cleaned the contacts or the whole parts in isopropanol over night. Let it 2 days for dry and put them together yesterday.
By connecting with my Notebook the connection/synchronisation was working. So I could see my music and photos. But the screen stayed black and I could not enter the pin.. While the connection the signal sounded constantly. Where is the problem? Do I need a new battery or new speakers? What can I do now?
Thank you in advance,
Es esta una buena pregunta?
