  • Samsung Galaxy S4 (SGH-M919) Flash I/O Error

    I just got my new RIFF box and I love it, but I still haven't been able to revive my phone. Getting closer though. One thing I found, is that the RIFF came with a driver for the "Qualcomm Loader" I would get when I was messing around with various software tools before I bought the RIFF. Plug in USB, wait for it to pop up in device manager, then load that driver, start JTAG manager and (attempt to resurrect) and I got this far.

    Lowered the RTCK to 1MHz and got it to detect, here's as close as I get:

    Open serial port...OK
    Connecting to the RIFF Box...OK
    Firmware Version: 1.41 (RIFFBOX2), JTAG Manager Version: 1.63
    Selected Resurrector: [Samsung M919 V1.0.5256.58262]

    Connecting to the dead body...OK
    Detected dead body ID: 0x2071B0E1 - CORRECT!
    Set I/O Voltage reads as 1.79V, TCK Frequency is RTCK
    Adaptive Clocking RTCK Sampling is: [Sample at 1 MHz]

    Resurrection sequence started.
    Establish communication with the phone...OK
    Initializing internal hardware configuration...OK
    Uploading resurrector data into memory...OK
    Starting communication with resurrector...OK

    WARNING: DCC Loader was unable to initialize FLASH1 chip. Error code: 0x02010035

    No Resurrection Data is available for the eMMC Chip with Capacity = 0B
    WARNING!!! Using Resurrection Data for the eMMC Chip with Capacity = 14,68GB

    ERROR: Selected FLASH Chip was not initialized by the DCC Loader.

    The flash size seems close - it's a 16GB S4, but perhaps the flash chip is a different type? It could also be dead, in which case I would need another motherboard, but I may as well ask if anyone has had success.

    Thanks,

    Rob

    "Error : selected flash chip was not initialized by the dcc loader "

    " Emmc chip with capacity =0 "

    These 2 log results indicates that the Emmc memory chip is dead.

    It's not fixable with any jtag box.

      New eMMC Chip

      Thats what I thought. I was considering a new mobo, but my friend has a BGA rework station. Anyone had success just replacing the eMMC chip?

      If I were to replace the eMMC, would I be able to downgrade to a lower firmware? I got 4.4.4 on mine with that Knox crap. I heard you couldn't downgrade, would I need a dump of an eMMC to program (I bought the eMMC activation)?

      Maybe it's better to just buy a new motherboard.

        Oh, Duh... 0 Bytes. Not 0x0B (which would be 11 anyway)

          I did buy the eMMC activation. If I were to replace the eMMC (which seems like too much of a pain - every BGA rework job I've seen has failed within a year), could I program it using the eMMC direct function with a lower firmware? Of does that snapdragon use the EFuses and I'm stuck with 4.4.4? I also noticed that my firmware wasn't listed in the resurrection. (VH7)
