    Hi folks,

    Trying to assist a friend with a JH7 Captivate S (i897) to do a stock Froyo update.

    From my limited reading it appears that a Win7 x64 PC is not a good choice for Kies Mini, and Samsung officially discourages the use of Kies for W7 x64. (W7 x64 is what I've got for better or worse)

    [ FYI - Tried installing Kies Mini 11011_4 under a VirtualBox Win XP x32 guest; it actually crashes the guest VM during driver install phase. That, and USB pass-through in VirtualBox 4.1.x is not 100% transparent. Makes me a bit nervous to flash the phone using a VM guest. ]

    So, a couple of questions:

    Q1) Is KB1 the last official (Froyo) release from Samsung? (sorry for the lamer question)

    I'm savvy enough to boot a Linux CD Distro and use Heimdall if necessary, so...

    Q2) Anybody here ever use Heimdall for a stock install?

    Q3) My (poor) understanding is that ROMs for Odin/Heimdall are slightly kanged versions of whatever Kies/MiniKies would normally download from Samsung - is that correct?

    Q4) That being the case - and assuming I can find it (KB1?) for download someplace (where?) - has anybody published MD5 sigs for these (slightly kanged) "official" Samsung ROMs?


    Any opinions or expansion on the above would be welcomed. I'm basically looking for a minimal-risk stock upgrade. As the phone is not mine, I'd prefer to avoid a multi-day adventure. (If the phone was mine, it would have been rooted a long time ago)

    [ Edit ]

    Answered some of my questions with more digging.

    - It appears that UCKB2 appeared on some late-shipped Captivates.

    - This XDA thread seems to be what I am looking for, although I suppose that the phone currently (JH7) doesn't have a Froyo bootloader, so I might experience some ... eh ... "kinks"

    as I said before, comments are welcome.

    First - happy new year!

    Epilogue:

    Got it done - eventually - by punting (finding a WinXp x32 box); only took me 5 hours end-to-end. (Backup user data, fail, fail, fail, fail, fail, fail, succeed, Restore apps & user data)

    Under Win Xp SP3 x32, Kies Mini 11011_4 (the download link at this Samsung Page) installs, performs driver installs, downloads and installs something called "Windows Media Format 11", updates itself to 11051_4, then re-installs some more drivers. This only requires restarting the phone three times in two different modes and rebooting the WinXp PC twice. I sure am glad Samsung made it easy for us. :(


    On Win7 Pro x64, Kies Mini goes through much the same process (but without the "Windows Media Format 11" install); the drivers all appear to install correctly; but alas, when Kies Mini finally is happy with itself, it fails to recognize the device in Download mode. I also tried the One-Click java/jar/Heimdall install with Win7 x64, but got stopped out with the same Java errors mentioned in here in that XDA thread

    Attempting a USB pass-through to a Win XP x32 VM guest (VirtualBox v4.1.6) is completely execrable experience - any attempt to install drivers results in an immediate VM crash - this applies to the Kies Mini USB drivers and also the Heimdall zadig drivers as well.

    FWIW, when Kies Mini runs (successfully), it drops it's download payload into a single file at

    C:\Documents and Settings\<username>\Local Settings\Temp\<something>.tmp

    This gets unpacked into a tar file and a .dll, both of which can be copied to another location while the flashing to the Captivate is in progress:

    I don't recognize the format of the 1A1.tmp file - it clearly must be compressed, as it unpacks from 193 MB to 300+ MB - but the lead-off bytes don't seem to contain any recognizable magic numbers.


    FWIW, here's the USB VID/PID pairs I noted for the JH7 phone in various modes:

    VID / PID

    04E8 / 681D Mass Storage Device
    04E8 / 6601 Gadget Serial (phone in Download Mode)
    04E8 / 681C SAMSUNG Android USB Composite Device (or Composite ADB Interface)
    04E8 / 68A9 SAMSUNG Android USB Composite Device (USB Debugging)
    04E8 / 6877 Portable Devices -> MTP USB Device (Kies Firmware Mode)


    Happy new years ... and thanks for all the help! ;)

    cheers
