  1. Hello!! I've been trying to flash the ROM for my Lenovo S820. But the problem is with my USB driver. I followed all the procedure. I could see the MTK65xx Preloader Device for a moment in the device manager and it got disappeared with a disconnect tone. So I immediately right click on that and update the driver. Installation completed successfully and so I rebooted my system. Later what have happen is that after connection of the phone I could see the Mediatek PreLoader USB VCOM Port on the Port options of the device manager and it got disappeared again with disconnect tone. And so I cannot initiate flashing. Please help.

    1. How will I know if flash tool have recognized the device or not? And I cannot continue the installation procedure as after connecting the device to the system it is showing Mediatek PreLoader USB VCOM Port for a moment and it got disappeared again. Yes I did tried again but its shows that the driver is up to date.

    2. just begin to follow step 5 until finish, don't bother with Mediatek Preloader USB VCOM that disappeared, have you been try to run your flash tool and follow step 5 and then connect your phone? if not just try it now.
      please try it first, and if you found a problem you can leave a comments, and i don't see any problem on yours

  2. I get the error response (8038) and asked to choose Firmware Upgrade over Download. After clicking Ok I again clicked on Firmware Upgrade then again I got a response saying “Please make sure all necessary images are being checked to be downloaded for Firmware Upgrade”. So again I clicked on OK and nothing happens. I started all over again without clicking Download and clicking directly on the firmware upgrade, it happens the same. Please help.

  3. Are you talking about "PRELOAD" which is not checked/ticked in the list ? Or it should have to have a button or drop down option like thing in the Flashing tool??
    Yes if you are talking about the PRELOAD then yes I could choose it from target_bin folder. But should I need to tick it before clicking to Firmware Upgrade??

  4. I could do the flashing successfully & I saw the green circle but I think I bricked my phone. It ain't starting even if I press the power button for over 30 secs. Please suggest me what should I do. Moreover I could see some changes that after connecting the handset to the system it starts to show like this in the device manager MTK USB Port (COM19)

  5. As per your advice I did re flash again with the same procedure but unfortunately I couldn't complete getting the error prompt: BROM ERROR:S_FT-ENABLE_DRAM_FAIL(4032)

    And hint is giving: Please check your load matches to your target which is to be downloaded.

    Please help !!

    1. you must fix your partition first before flashing this ROM, your partition is mess, i don't know what have you done but you already messing your partition so the ROM cannot in into your device because the partition is not fit or maybe your device is not Lenovo S820. this error message mean : The size of a file is larger than the available / possible partition size Solution: * Ensure that the file(s) you're trying to flash are actually for your exact phone model * Try another stock ROM try search on the net how to fix it.

  6. My s820 china version hav had vibe with modem v51 and now has row_s223 with modem v105…., it seems to me that gsm signal is weaker.
