  18. Dewald Nel says:

    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 ?

    • Sumit says:

      Yes you can use the above method to downgrade

      • Dewald Nel says:

        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.

        • Sumit says:

          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 says:

        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..

  19. Dewald Nel says:

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

  20. Giel says:

    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?

  21. Dewald Nel says:

    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.

  22. Dewald Nel says:

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

  23. Dewald Nel says:

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

    Hi Sumit

    I am on a Vodafone (South Africa) build VNS-L31C02B329.
    I have read European roms/firmware will work. This true or is there specific files for Africa.
    Issue with Vodafone build is that they disable the dual sim capability in the firmware. Would like to flash with stock rom to enable dual sim management.

    Hi, Thanks for your great. I have huawei p9 lite from Pakistan on nougat. can you please provide me files to downgrade for this model.

  48. Cobus says:

    What is the meaning of the CxxBxxx in the build version. assume this is for different service providers and regions? Yet for Eur you get B336 and B889 for L31. Just a later more current version or different build altogether
