Installing a custom Lenovo A850 ROM using Flashtool

lenovo a850 narrow

Welcome to another tutorial about installing a ROM on your phone. Again, we’re taking advantage of the flexibility of Android to simply change your operating system by flashing different software over.

For this simple step-by-step guide, we’re going to be using a Lenovo A850 and using the Flashtool software to directly install a new ROM on the phone.

Today we’re going through the basic steps to flash any ROM dump. The ROM we’re using is the S123 Lenovo Stock ROM which includes Google apps and will allow you to install other custom ROMs later.

Before we start though, a disclaimer: by flashing over USB or installing custom ROMs, you may be voiding your warranty. We take no responsibility if your phone is damaged or bricked by following these instructions. Always backup your phone before altering its software in any way.

Initially, you need to make sure you have installed the Lenovo USB drivers. Download the drivers and the Flashtool as well as the ROM file itself. It’s important that you ensure you are using the exact version of Flashtool we’ve included here (v3.1320.0.163) as other versions might not work.

To install the drivers. Turn off the phone (don’t use the quick boot option) and take out the battery. Open up Device Manager and plug the phone in via USB – be ready to quickly right click on the device that appear and choose “Update driver”. Using the wizard, select the drivers you downloaded previously. If you are having issues, installing the drivers, use USBDview to ensure that you have deleted any existing MediaTek USB drivers that might be on your computer.

Next, unzip the ROM file and make sure you can open Flashtool on your computer. You are now ready to start following the instructions in the tutorial video below.

What ROM did your Lenovo A850 come with? Do you have a preferred ROM for the Lenovo A850? And how easy do you find installing new ROMs with the Flashtool?

    This is a big NO NO. My lenovo a850 phone is dead after using the rom provided here. Can’t boot to recovery either. It is also not detected by Flash Tool after the flash. JUST DON’T USE THE ROM. I don’t want you to be the next victim.

        Hi there,
        I have just flashed my LENOVO A850 using your instructions and once the green ring appears I have disconnected usb cable and putted on the battery.
        And from here I have realised that my phone is broken. When I tried to turn on the CWM using vol + – and power on buttons, there is no action at all.
        I also tried to turn on the phone normally but there also no effect.
        Another step was, that I tried to flash my phone again, but know when I am trying to do this, flashtool can’t se my phone when I am trying to connect phone with usb cable… Please help

      hi Kian, i have a a850 having same issue as you,
      do you mind share how did you settled the problem?

      my situation is as below:
      phone cannot ON
      phone not detected by PC
      won’t charge
      have red indicator if charge without battery

  43. Jim 26 October 2014 at 02:57 Permalink

    Try Lenovo’s own flashtool, “Lenovo Smart Assistant” & copy rom into the dir. where you installed it.

  44. Kian 16 October 2014 at 02:42 Permalink

    Further, that is the time that the flash tool will shows this message enable dram failed (error 4032)

  45. Kian 15 October 2014 at 09:34 Permalink

    It seems most of us have the same problem… After successfully flashing (indicates with a green circle), the phone doesn’t turn on anymore. Is there a solution for this?

    Currently, my phone condition is-
    1. Does not turn on
    2. Does not charge either
    3. Doesn’t detect by pc anymore
    4. If you plugged in a pc via usb without battery the light in the upper right corner turns red.

    I hope someone help us.

    • Mobile Network Comparison 15 October 2014 at 11:15 Permalink

      What about recovery and download mode. What exactly is the model of phone? And what did you try to flash? Can you show screenshots of screen capture of what you did?

      • Kian 16 October 2014 at 00:02 Permalink

        My phone model is Lenovo a850 and i try to flash this Lenovo Offical English S123 ROM (v.2.3.5a) rom from your site of course. The thing that bothers me is your asking the same question every time. I’ve look in the previous post (A. Ibr, Helmi and Hugo) and your just keep asking “what exactly happen?”, “can you go to recovery mode?” even though we have stated that the phone doesn’t turn anymore.

        • Mobile Network Comparison 16 October 2014 at 00:15 Permalink

          There’s a difference between not turning on and not entering recovery. If there’s any hope of helping, we’ll need many more details to try and troubleshoot.

          • Kian 16 October 2014 at 01:23 Permalink

            Sorry for what I said, It’s just I am worrying to much on my phone. Well like I said, my phone doesn’t turning on nor entering recovery mode. And there is this error that pops up in SP tools it says like enable dram failed (error 4032).

            • Mobile Network Comparison 16 October 2014 at 01:26 Permalink

              No worries. However, we’re sorry but there’s really not enough infomation to go on to give useful advice. Maybe try taking it to a phone shop?

              • Kian 16 October 2014 at 01:36 Permalink

                Well, I guess i have no other options. But just a question, Is it possible to unbrick a “hard brick” phone by using software? For example this lenovo a850? Thanks.

                • Mobile Network Comparison 16 October 2014 at 01:37 Permalink

                  It’s impossible to tell when it is indeed hard bricked at this moment in time. Can Flashtool see it?

                • Kian 16 October 2014 at 02:40 Permalink

                  My PC actually see it when i press power + volume up and down, my pc will detect the phone then after 3-5 it will disconnect.

                • Mobile Network Comparison 16 October 2014 at 02:42 Permalink

                  Sounds like it’s not completely dead then. Did you have drivers issues to start with?

                • Kian 16 October 2014 at 11:41 Permalink

                  As far as I know, I have installed the correct drivers for this device. Is there any flashing tools that I can use other than SP Flash tools?

                • Mobile Network Comparison 16 October 2014 at 13:19 Permalink

                  Not that we’re aware of at the moment.

  46. Eduardo Cupertino 13 October 2014 at 22:20 Permalink

    Yes, a little. It is facinante… Now notice that the loading screen of the ROM is different from that of your video. Another interesting detail, my dear friend, is the recovery mode has letters in Orange and not blue: A top of Recovery System is “Adnroid system recovery “… We wonr too this “CWM based recovery v6.0.3.0” =) Thanks!

  47. Eduardo Cupertino 13 October 2014 at 16:07 Permalink

    Thanks for your answer. With me the windows 7 ever decides the “better” driver. So i Turn off the “Windows Update device driver searching” at Computer Properties, i have deleted the “MediaTek Preloader USB VCOM Port” but… This name returns after manual driver update and the installation firmware runs with this drive. Now i am happy with the english finally. bye

  48. jo 13 October 2014 at 07:26 Permalink

      If my driver folder is wrong, PLEASE somebory post driver at google or 4shared!!
      So.. Thanks and
      Tomorrow i try on a Windows 7 computer.

          HELP ME Guys! Now i came back again, in these days i spend a lot of time, plug and unplug the mobile on PC munch times. I removed the MedTek USB wrong driver and on Windows 7 (in my work D: ) consider fine the “Lenovo PreLoader USB VCOM (Android)” where tell thats runs correctly. My problem is: THE DEVICE CONNECT AND DISCONNECT IN 2 SECONDS. Appear and disapper on Device mananger. The preloader line is RED in FlashTool. Used 2 USB cables on 2 differents PCs and ports. Please how can i solve it?

    • Mobile Network Comparison 12 October 2014 at 18:24 Permalink

      Yay! 🙂

      • Eduardo Cupertino 19 August 2016 at 15:54 Permalink

        😀 How are you, guys!? I finally found the solution, so the energy port should be broken (so hard to recharge) and USB connection on PC never runs again because i have do wrong steps. Sorry my words my friend but MediaTek driver run fines, so easy and fully functionality for me. I dont understend because has needed force windows to remove driver. If i skip the driver installation’s step should be more happy to me. Thanks a lot for these tutorials! Don’t see my english errors – i am at work 🙁 .

        Tchau pra vocês!

    Did you find a solution. Me too have the same problem

    • Hugo 7 August 2014 at 02:54 Permalink

      Unfortunately not.
      I’m talking to a manufacturer to see if I can find a solution.

      • Abhishek Nirmal 7 August 2014 at 03:36 Permalink

        HI Hugo/A.lbr,

        I think when you tried to install custom ROM using flashtool it got stuck in the process and the phone is not turning ON right? It happened to me as well. Solution – let your phone be connected via USB and open flashtool and try to repeat the steps – it will pick up from where it was stuck in the flashing process(in flashtool). give it a go.
        thanks
        Abhi

      Can you get into recovery?

      • Kian 15 October 2014 at 03:18 Permalink

        This is exactly what happened in my device. No! You cannot get into the recovery for the reason that your phone won’t turn on anymore. Please help!

        • Mobile Network Comparison 15 October 2014 at 03:33 Permalink

          What about download mode? Does the phone ever show any sign of life?

          • Kian 15 October 2014 at 08:11 Permalink

            Same result sir. My phone doesn’t response anymore. Is there any way to fix this? Thanks for your reply btw.

    Thank you MNC, I managed to flash my phone. excellent tutorial.
    @Roy: please open the device manager first and then connect your phone via US. You’ll now see your device, quickly right click and update driver and select the folder where you have saved the usb driver files. Do not worry about which setup file, the wizard will automatically detect it, you just need to point it to which folder the USB driver files are.
    cheers and good luck.

    SP FLASH TOOL NOT DETECTING MY PHONE SO HOW?

  81. Agicaniac 23 March 2014 at 05:06 Permalink

    http://download.verticdn.com/mania/query.php?q=Lenovo_Drivers_SP_Flash_Tool_v3.1320.0.163.zip&ti1=1585000&ti2=0&ti3=2014-03-20T01%3A59%3A50.558384%2B00%3A00

    this link leads to another file with extension .exe which contains trojan.

    I somehow managed to get hold of the flashtool and tried.
    Everything was ok up to the step where I had to plugin my turned-off a850. Flashtool couldnt detect it. What can I do next?
    Many thanks!

    • Mobile Network Comparison 23 March 2014 at 16:27 Permalink

      Are you sure you’re actually clicking the correct download button. In the links we gave there’s nothing with a .exe extension.
