  1. andy..
    this rom can select default write storage? can receive OTA updates?
    and what's the difference with S121 by Linerty ?
    i heard everyone said S121 by linerty is the most STABLE rom for lenovo a850.

    have u experience any issue with this ROM?
    kindly advise 🙂

    1. Hi,
      No there is no option to write default write disk to ezternal memory, i think s121 is a modified rom so it has the option. For OTA update as long as you don't modified rexocery file, i think you can still received and do OTA update. I believe latest version fix previous version bug, so if you feel s121 is stable than s127 is more stable that it.

  2. Hello.
    So I followed your instructions but when it come to actually flashing the phone it came up with this error:

    SP FLASH TOOL ERROR: ( 8038 )

    [Android Download] PMT is ready and Layout has been changed!
    Please use FIRMWARE UPGRADE instead of download to avoid important data lost.

    So do I follow as it says?
    Sorry am new to this….

    1. Hi Andy,after done flashing s128 rom,my phone cannot turn on,cannot boot to recovery and my pc does not detect my phone.My phone came with CN Firmware,so i decided to flash this rom.Hope you find the solution.

      Please reply as fast as you can

      Thank in Advance.

    2. hi,
      remove battery for a view minutes, don't put it back. after few minutes try to connect your phone to your computer, see if your computer will detect your device as PORT. if it detected just flash the RIGHT rom for your device.

    3. how if you do flashing with flash tool, are your device got detected by flash tool ?
      because this can be your device not show in the computer device manager but it already become PORT and can be detect by flash tool. Or it can you flash the wrong file and shutdown your device.

    4. you only need to flash it back, but if your phone completely dead it called hardbrick it because you wrong flashing ROM to your device that make your phone preloader missing. if this the situation then you must bring your phone to lenovo service center because only they can fix it

    5. i thought you ask to muhammad huzaifah, it depend is your device is detect by your computer or not ?
      if yes what show on device manager while your connect your device, is MTK preloader VCOM USB or else ?
      if not then bring to service center for motherboard replacement,

    6. thanks andy for your fast reply message..its detect nothing..when i charge the phone led notification didn't show any led color..but if i connect the phone and pull the battery out and connect to pc..only red led appears..i have no warranty anymore..any idea why i need to change my motherboard??..i'm really thanks to you andy..while i'm frustrating with this problem you are here to help me and explain to me..

    7. i mean is, try connect your device without battery then look at device manager on your computer. What it show ?
      many update erase the preloader on the device motherboard, so it need to change. So the motherboard know that it Lenovo A850.
      Mediatek Preloader USB Vcom –> show this on normal motherboard, else then bring to service center to replace motherboard

    1. hi,
      lenovo has 2 version firmware, china and international version. This guide is using international version which is remove all china settings and china applications and it already include google applications.
      I guess your firmware now is china version, because it contains china language and china applications

    can you please advise me what rom should i used and how?
    thanks in advance.

    1. hi,
      first make sure you already completely root your phone, use check root tool on the play store.
      stuck on logo can be solve by factory reset the phone or reflash again.
      if you flash the right ROM using flash tool i think the problem will not show
