    N70 matot water damage.
    sudah cuci ultrasonic.

    di-chk dgn ufs:


    CMT 1ST Boot Err: Bad Resp RAPx,
    Rebooting Mobile


    sw on pake power suplly, jarum amp naik sedikit (kurang dari 0.1), lepas sw on, jarum amp kembali ke nol.
    cek tegangan:
    - vio a.l. di: C2215, C2240, C2241: 1.80V
    - vddr_ape a.l. di: C4205, C4206: 1.00 (mestinya 1.8V)
    - vcore a.l. di: C2302, C2243: 0.00V (mestinya 1.4V)
    - vcorea a.l. di: C2242, C4200: 0.00 (mestinya 1.4V)
    sdh ganti retu, krn dugaan saya retu bermasalah, tapi tdk berhasil.
    yg jadi masalah vcore dan vcorea tdk ada tegangan.
    minta tolong..
    apa tindakan yg hrs saya lakukan.!
    thnx.!
    nb:
    - kabel flash ok
    - sdh cek pake mxkey, jaf, juga tdk berhasil.
