    Hp masuk dalam keadaan matot, cek pake ps konsumsi 25
    lalu turun & bertahan di 20mA.....

    cek diUFS, "first boot error", kmdian coba akur-ukur..:

    VIO : di C2215-c2240-c2241 >>> 1,8v = ok

    VANA: Di C2217 >>> 2,5v = ok

    VCORE : di C2807-C2800-L2302 >>> 0 = ??????? shrsnya 1,4

    Vr1 : di C2214 >>> 0 = ????? shrsnya 2,5v

    PURX : di C2235 >>> 1,8v = ok

    RSTX : di C2316 >>> 2,8v = ??? seharusnya 4V

    SleepX: di j2215 >>> 0 = ??? seharusnya 1,8v

    Dar hasil pengukuran diatas bagian yang manakah yang perlu dieksekusi

    Mohon pencerahannya Master & Agan2.....

    CATATAN : Board Mesin keliatan masih MUlus Dan blum berani obok2,
    sblum dapat pencerahan....


    THANKs

    Sebelum di switch On, apa arus setinggi dg arus akhir xg tertahan di 20mA.?
    Klo iya, ponsel dlm keadaan short.!

    Jika normal, seandai'y Gw :D.. melihat urutan proses PULS, akan jatuh pilihan utk eksekusi RETU duluan.
    Coz.. tanpa RSTX xg normal, maka TAHVO tidak akan bekerja (tidak ada Vcore)
    Tidak ada Vcore, maka RAP tidak akan merespons sleepx n aktifasi tegangan VR RETU
