    1. On recovery or on home screen, on recovery cannot touch is when you install twrp because of this bug on my guide that install twrp i don't give link to download twrp because it bugged. If on home screen just try to install or flashing china rom for your device. Look like europe firmware does not fit with china devices, so must back to china firmware

    1. Hello,
      Vibe ui 2.0 can only be install using zip method, from china official firmware. So first you must install china version firmware then updated it to obtain vibe ui firmware. But i am still afraid to modified Lenovo S850 for now. Because once it loat it IMEI difficult to fix it and restore the phone capability. So i only have few guide about it. And for update to vibe ui i still don't have yet.

    2. yes, both.
      Vibe Ui 1.5 and Vibe UI 2.0 need to install from china firmware with original recovery. Your firmware is ROW modified by the shop who sell your phone.
      and for update to VIbe UI 1.5 or Vibe ui 2.0 i don't have, but i have this http://bit.ly/1wNn45W latest version of international ROM. remember to backup your curent ROM and IMEI first before starting modified your device

    3. yes it the official web for Vibe UI, you can try it but do with your own risk. i already told you if your Lenovo S850 lost IMEI it will be hard to restore it.
      Ok just try it, it can and it official web for Vibe UI, so everything is on that web is legit

    1. i think it must be broke on one of the part, like the ic or component so it does not recognize the internal storage of the phone, internal storage in this mean emmc that use to store RIM image. try bring your device to lenovo service center and told the story to them

  1. Andi maaf saya pakai bahasa indonesia.
    Ternyata didalam firmware yang ini, file EBR2 tidak ada.
    Begitu juga didalam file scatter juga tidak dideklare untuk partisi EBR2.
    Otomatis file userdata.img tidak bisa diflash karena tidak ada partisi yg menampungnya.
    dan muncul peringatan error: BROM ERROR : S_NOT_ENOUGH_STORAGE_SPACE (1011).
    Saya mencoba flash tanpa file userdata. jadi hanya file system dan cache yang masuk.. ini menyebabkan system bootlop saat pertama kali dihidupkan.
    demikian koreksi saya.

    1. This ROM is modification from china ROM add with multi language features and gapps so i think it should be flash to device with china version ROM as previous then hit firmware upgrade, so it still use old ebr2, but anyway thank you for your info should write on english so anybody can read it and got clue from your comment
