    1. Hi Andy, after hard reset, my s820 show bn row s221.
      There is ota alert to upgrade to row s222, but i got android error icon after the process. And s820 reboot and inform ota upgrade failed.
      Pls advise how i can update row s222.
      Thank you

  1. Hey Andy
    I've a doubt, my previous firmware was S820_S221_ROW. I had convert row to chinese markings!
    Now I'm Running China firmware with VibeUI 2.0.. My question is if I want torevert it back to ROW, how to do it?. Has to again convert Chinese to Row or can install the Firmware S820_S221 4Gb directly…

  2. But I already have S820_ROW_S221_140730_OTA.zip which is 179 MB file. Can i used the 179 MB file directly to flash it or must download the file that you mentioned above S820_S221 —-> 715 Mb, contains all images file to upgrade your Lenovo S820 to the latest firmware, only for 4Gb

    1. From china to ROW you must use rom that contains all required images to flash, cannot use OTA like yours, OTA can only be use to update from previous version, like from S220 to S221 you can use OTA update. But for change version you must use full images ROM and using flash tool to install

  3. Thanks For your reply Andy.. You save me..
    by the way i finish install the rom that contains all required images so next i want to root it, what ways you suggest me!
    And I would let the chinese firmware but when i try to install any custom rom onto the chinese firmware it successfully installed but the problem is the rom doesn't run or boot it just remain on the bootloop for hours.. Last night i've installed the MIUI_V6_4.11.21_S820_LETZ but when i reboot system in recovery it just don't load the ROM and i've let the phone for hours but still doesn't start…. So my friend what is the problem here and that's why I have reverted it to my previous ROM S820_ROW_S221_4gb

    1. hi,
      when you got bottloop after installing a firmware first thing to do is try to factory reset first, sometime it need to format data and cache first before success to boot. and one thing you should know that first boot is longer it can take 5 minutes to boot.

    1. can be download from any website but with the same phone model and the same firmware version. but it dont guarantee to work because the file has md5 that note on the checksum.ini file.
      so recommended to download from the same site

  8. Im installing the S820_ROW_S221_140730 then the S820_ROW_S222_141121 (222MB)
    after that will download the S820_ROW_S223 which is 1.6GB I think … I hope the S820_ROW_S223 doesn't drain the battery 🙁

    One Simple question ! Can ROW version install custom ROMS or must convert into CN version to be able to install Custom ROMS… I've found Xperia Z3 rom nice… Many users has installed and has yet any trouble.. the rom is smooth running well 🙂 Thus I'd like to try it….

  9. Hey Andy Thanks for the approval mate !!
    I've finished flashing the Lenovo S820 Update to the Latest ROW Firmware S820_S221 4Gb … WHAT TO DO NEXT ? HOW TO ROOT THIS ROM ,,, ANY GUIDE PLS SHARE IT
    AND YEAH DO I NEED TO FLASH the " Recovery TWRP KITkat " too … Please answer fast dude ^^

  10. My phone is : S820_ROW_S223_150119; and baseband S820.ROW.V105 and whenever I tried flashing any modems.zip in TWRP. It does flashed 100% successfully but still the modem doesn't change… it remains the same(V105). WHY ? And another issue is when I switch to WCDMA ONLY no network available at all.. Neither in 2G/3G auto, doesn't get 3G. Therefore; I just put it in GSM(2G) and it gets full signal five bars. But for the 2G it is soo weak when connecting to Facebook or browsing it takes hours to connect 🙁 I want that 3G no matter what I'll try every single shit to fix that. My Sim Card Provider is Orange, I'll try another Sim Card like Emtel to see if I can get 3G

  11. Hi AS,
    I was installed the Media Tek Preloader USB VCOM driver in my computer but it is not permanently exsit in Device Manager. Once I was pluged USB cable to Handphone the Driver will appear about 1-2sec then the Driver disappear… Any problem of the driver? Let say if I continue next step?

    1. Hi,look at download sextion about usb vcom.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.

    1. your problem maybe on hardware, because flashing don't effect on screen problem.
      usually the problem is brick or cannot load system not on hardware, try check your screen it is broke or maybe there is cable inside it that not connect, if you dare to unpack your device.

  12. My S820 stuck on boot loop. After a few days, it won't turn on and have no response when I press all button/combination or connect with charger. Does flashing this stock rom can recover my phone? I don't care if it need to format all things.
