    1. hi,
      above guide is also use original firmware of Lenovo S850.
      if you ask me your original ROM then i don't have it. I buy and i have ROW_S216 then this is my original ROM, different phone have different original ROM so that why i always told to backup original ROM first before modified.
      and to save or backup IMEI use MTK droid Tool http://bit.ly/1kcsUqj, if you mean save is fix then use maui meta 3g http://bit.ly/1teLvmQ

  2. Hi, I bought lenovo S850 in china and i have the ROM VIBEUI_V9.5_9422_3_ST_S850, if I update this ROW_216, I would have any problem? with Imei or modem? How can I replace the modem file? Thanks Andy

    1. Hi,
      I cannot say tge problem you will get because it sometime give problem but sometime it smooth. My suggestion is root your device first, then backup your full ROM and imei using mtk droid tool. Then try to update, all the guide can be found on my blog.
      Rooting using kinguser application, backup using mtk droid tool

    2. Ok, I have root access i will try make backup with MtkDroidTools v2.5.3, then I will install this ROM, I hope dont have problem with Imei. And about the modem file? How could I resolve if I have that problem?

  3. Thanks you are save my phone my phone is hang on boot but i downloaded this and it fix my mobile thank you sir but please remove your twrptwrp because i use it and format my mobile but he damage my mobile but now ok….. But please remove twrp gives link for cwm ….

    1. hello sir , i have some problem during update lenovo s850….so update is cancelled…so my mobile have only four options reboot , switch off , update , wipe user data……when i press update it will be cancelled…..so what can i do for getting normal phone….

    1. no, twrp backup will backup all not only nvram.
      Lenovo S850 does not support OTG, Yes i think you can install samsung music and gallery but you need to know what libs that need for samsung music and gallery so it can be run on Lenovo environment.

    2. But when i open twrp recovery, its able to take backup of nvram only.. So would you suggest me to take nvram backup through twrp recovery??

      And can you tell me how to install samsung music and gallery app to my s850?????

    3. if i being you i would not take partial backup on twrp, and i ask you how you restore the backup? after install new ROM you need to install TWRP again with the same version and the restore. If you backup with flash tool it can be restore using flash tool no need to install TWRP first or root first.
      just copy it to /system/app on your device.. i hope you know what i mean….

    4. I just flash rom Row_216 into my s850.. and I AM FROM INDIA..
      When i open easy image ####682#, there are many codes available like PK, SA, TR, TH, IN, UA, CO, RU, PH, and MX..
      So i want to know what is easyimage when i open ####682# and what its importance and what its work??
      and For me, in INDIA, Which one should be selected??
      Plz Reply me…..

    1. as far as i know /system/vendor is to store application that include by the developer, or application that cannot be delete even with system restore, and for preloader.img i don't know but as far as i know sometime preloader not included. But as far as the ROM work and everything is work i think there is no problem

  4. Yesterday my S850 was bootloop when it failed to upgrade its firmware from lenovo system update. And my bad, I never backup my phone. So I tried to flash it with thus version.

    1. modified Lenovo S850 having high risk on losing IMEI, and NVRAM partition.
      without those 2 you will lost your communication ability.
      so always be careful and prepare for every risk.
      the answer is yes, but the problem can be solve also.
