    pastikan jalur dati tiap part yang terhubung OK
    cek resistansi dar PIN/kaki tiap2 part siapa tahu ada yang SHORT ,,
    kalau IC nya gak di lem coba REHOT atau Ganti ..

    logikanya jika jalur OK, dan part penghubung/pendukung OK banyak kemungkinan untuk jalur D+/ D- bisa terhubung ke prosesor ..
    terkecuali prosesornya bermasalah ..

    1,1 amper short loh boss ...

    hemmm diulang dari awal dulu aja ya ..
    coba cermati gambar berikut
    bb 8520.

    coba ukur tegangan seperti digambar ...
    atau cek kapasitor dari tiap2 kapasitor yang bergambar tegangan .. kira2 ada yang SHORT ndak ?

    Coba pastikan lagi besaran ampernya boss.. 1,1 A atau 0,11 A ? ... Coba buka skema, cek jalur VDIG 1,8

    ini gambar amperenya dan gambar multitester, pengaturan multitester buat mengukur short dan tegangan nya udah bener belom bang rio ?? barang kali salah di pengaturan multitesternya :), dan itu saya ngukur waktu hp kondisi lepas baterai. . . :)

    Owh ...

    Kalau saya biasa pakai multitester analog, pakai X10
    Untuk power suplynya itu terbaca 0,11 A boss ..

    Kembalike topik, biasanya BB ndak bisa kedetek ada beberapa macam penyebabnya, - konektor USB rusak, - jalur USB yang rusak, - tegangan VBUS hilang, - komponen yang terhubung D+ D- bermasalah, - IC West Bridge rusak ., - Prosesor yang sudah lemah ..
    . Kembali ke kronologi kasus, flashing terhenti ditengah jalan .. Bisa jadi komponen berlambang U dijalur D+, D- bermasalah, atau bisa juga IC WB nya rusak,
