    hi, i updated from VNS-L31C16B120 to unofficial nougat VNS-L31C432B371 via the HiSuite method. Now I have NRD-90M test keys and bluetooth doesn’t work + lost system apps and flashing the data package doesn’t change anything.. any way that i could rollback ?

      • Dewald Nel Reply

        Are you 100% sure, i mean it’s a very diffrent marshmallow version that I’m coming from.. and i need a guarantee that it’ll work cause im not close to a repair shop.

        • I’m not 100% sure because not personally tested by me but the above file will set your C432 build device to rollback package C900 after that you can install the Marshmallow Firmware. Also you see from above comment one user tried it on NRD90M test-keys and it worked for him.

      • Dewald Nel Reply

        Are you sure ? Even coming from a completely different build number of MM ?i need this to work 100% as I’m not close to a huawei repair center..

  13. Dewald Nel Reply

    Could i also use the B130 Update.app regarding my above question ?

  14. Hi, i already did the instruction. It works. But, when in initial setting i get stuck on wifi+ srtting. When i tap allow, it shows a glimpse of google acciunt login, but it back to wifi setting. I cannot get back to previous setting cuz the softbutton doesn’t appears.

    I try to restart and skio the wifi connection, and it cannot as we cuz it ask me to insert SIM or connect to internet.

    Do you have any suggestion?

  15. Dewald Nel Reply

    Hi, so this will work even though I come from a diffrent version of marshmallow ? I’m stuck with NRD-90M test keys… read comments above.

    • Christos Tsigkos Reply

      Yes, it will work for you. I was in the same situation as you, but I followed this tutorial and worked perfectly for me.

      • Dewald Nel Reply

    One last question..does flashing the rollback pakage ( the one you flash first ) wipe user data ?

    • Yes, Rollback operation will erase all user data. You should backup all your important data.

      • Dewald Nel Reply

        yes but I mean before i flash the Big Update.app… what will the first file do ( the one im supposed to flash first ) ??

          • Dewald Nel

            and it wont wipe anything.. only second file wipes data ?

          • Sumit

            Yes but still take a backup first before flashing the first file.

  17. Dewald Nel Reply

    i flashed the first file, and it said Update success, but the build number is still NRD90M test-keys

    If I’m rooted is there an easy way to get it so that I can use the 3 button method, I have the roll back package downloaded but have been really struggling but I notice that you say above it doesn’t work on rooted devices, I didn’t realise this, now I know why it hasn’t been working.
