    3. Hi andy suwito.. why your stock room after flash, my lenovo can not turn on.. five times i try to connect with my laptop but still can not detect.. i think your stock room problem because many user same problem.. i remove baterai but still same can not on..

      why…?

    4. try this "luckily while flashing, connect the phone with (power button) + (volume up) + (volume down) pressed work but need repeatly to do that. tq andy suwito for your guide and latest update. before that i remove all vcom+mtk driver with usbdeview and install it back. continue to update the latest information in this site."

    1. but tutorial said
      6. Unplugged your phone again and load a850 127 ROW scatter file this time. Make sure that the PRELOADER BOX is untick/uncheck to avoid messing your PRELOADER again.
      the preloader must untick if i untick the preloader i cannot press upgrade button

    2. as far i know error 8038 can be solve with pressing upgrade button, and 8038 is because scatter file not fit with device partition. and you right upgrade button cannot be click when not all box is ticked, so maybe try to tick all box then press upgrade after all you already know how to repair messing preloader right?

    3. sorry, don't have anymore just like above link that i give you. It look like the answer for me that the other site.
      last solution is bring to lenovo service center. But you can try it again and again as far as i know still detect by computer it still can be fix

    1. then you must install the USB VCOM driver correctly,
      Install this driver first on your computer, Turn off your device and remove the battery, using USB cable connect your device while look at My Computer ↦ Manage ↦ Device Manager there will be MTK65xx Preloader Devices show up for 5 second than disappeared, before disappeared right click on it and select Update Driver Software point it to USB VCOM Driver extracted folder. When it finish disconnect and connect again there will be Mediatek PreLoader USB VCOM Port on your device manager.
      try install USB VCOM first.

  1. My phone Lenovo A850 (MT6582) bricked just now. I accidentally pulled out the USB cable when it was flashing stock ROM by using Smart Phone Flash Tool. Now it's not charging and won't turn on, like a dead phone. I can get into MTK Meta Mode by pressing Volume Up & Volume Down then connect the USB, with and without battery. But when I try to flash anything, it gives error 4032. Please help me this is not my phone and I broke it! It does nothing when I press power button. also when i tried to connect my phone to pc it says "usb device not recognized".

    1. preloader is broke, so the step is you must install preloader first and you finish install preloader then you can install the ROM, search on the google for error 4032 you will find downloaded preloader about that error code, download install it and the install the ROM.
      never pulled out the USB while flashing

    Most of the people is see here does not have any idea of what they're doing. It's ok, since you're still
    new in flashing. But what our friend ANDY SUWITO did not mentioned is how to do pre-flashing preparation
    before flashing your new ROM.

    1. Check whether your phone is ROW or CN:
    ROW is REST OF THE WORLD and CN stands of CHINA, the difference is most of the Phone out of China is considered
    as ROW. However, some of you may have a CN phone, which is why sometimes a ROM cannot work when you try to flash it.
    Easiest to say, ROW ROM cannot work with CN ROM and vice versa. You can try but I don't recommended as this would cause
    issue and if you're lucky, your phone might work on both.

    2. Backup your NVRAM: Rooting your phone and installing TWRP.
    A little about NVRAM>
    NVRAM is the file which stores your phone mobile information such as IMEI or Wi-Fi information, and others. By damaging
    your NVRAM, (flashing or FORMATTING) it will render your phone to register to Mobile Network / Wi-Fi. To know if your phone has
    damaged NVRAM, your phone WILL SHOW INVALID IMEI (for SIMCard) and NVRAM ERR when powering WI-FI ON.

    To prevent this, root your phone first using FRAMAROOT (at least version 1.9.2 or latest). Find on how to use FRAMAROOT
    by Googling, and after done rooting, Download MOBILE UNCLE TOOL from Playstore. Download the TWRP 2.5.0 for Lenovo A850
    (GOOGLE) and Update/Install Recovery using MOBILE UNCLE TOOL. Google on how to use TWRP to backup NVRAM. Once done, keep
    that NVRAM file very safe which u can use it ON A RAINY DAYS while flashing.

    3. Download MAUI META 3G Tool just incase:
    MAUI META 3G TOOL is a tool for recovering your NVRAM (Write IMEI), you could Google on how to use it. I cannot explain as
    it takes a lot. But I'm sure you can if your phone is Dead and you want to fix it.

    4. Download A LOT OF STOCK ROM:
    When I say Stock ROM it Means the Official ROM not the Custom ones. Some phone might not work with some ROMs, therefore, you
    need to have at least three (3) Stock ROM if anything happens. You can get the best Stock ROM from Needrom.com (GOOGLE IT). Please
    make sure you're downloading the STOCK / OFFICIAL ROM which flashed by Flash Tool not CWM/TWRP.

    5. Use the Provided Flash Tool by the Stock ROM:
    Different ROM support different FLASHTOOL, therefore, use the ones that has been provided by the poster / blogger. Don't try to
    use others as this could BRICK YOUR PHONE.

    6. Try to Understand Flashing by FLASHTOOL OR TWRP/CWM
    There is a major difference between both. FLASHTOOL can be used to restore DEAD (HARDBRICK/SOFTBRICK) phone by replacing the
    entire System of ur phone. While TWRP/CWM is only UPDATING THE FILES IN YOUR PHONE'S CURRENT ROM.

    By saying this also, when trying to flash by TWRP/CWM, and your phone BOOTLOOP (SOFTBRICK: STUCK AT LOGO), this is due to the
    Previous ROM is not an Odexed ROM which is a DEODEXED ROM. The difference between both? Google it urself.
    Most Stock / Official ROM is DEODEXED, and most Custom ROM / fLASH BY TWRP/CWM is Odexed, (safe to say). Therefore, when trying to
    install Odexed ROM on a Deodexed ROM, it will not WORK!

    If you're insisting to install like EXAMPLE MIUI ROM, you must flash a Custom ROM (Odexed like Linerty S121) for it to work.
    Never try to install Odexed ROM on Deodexed system.

    7. Keep the best ROM (Stock/Custom/Ported) which works for your phone.

    P/S:
    Andy Suwito, you did a good job but next time, please do a lot of research on flashing as this would mislead and bring issues
    to anyone.

    Also please include "I'm not responsible if anything happens to your phone, you're welcome to try, but will help as much
    as I can to fix your problem" on your future blog.

    FYI: I am KindaDespair (Creator of Viberom Whitehorse for Lenovo A850 and a Moderator of LepakSpot.com). I've done blogging and
    creating ROM but will help those in need of assistance with China Phone.

    Good Day Everyone and Best of Luck!
