    Thank you so much, I have a TL10 gold 32GB and now i'm booting on B571.
    I've used the B512 for about a month now, and the battery life isn't as good as it was on the B324(lollipop), so i was wondering… How is the battery life on the B571 and how would you compare it to previous versions ?

  12. I have used B571 for few days, and its battery life is better than lollipop

  13. El ho says:

    Thank you!
    +1 for the good work
    i subbed to your Google+ and your youtube channel.
    Greetings from Morocco.

  14. Hi, I have the firmware B331, and when I tried to install B571 it says that the actual firmware (b331) its not compatible, so, what can I do, should I wait? thanks for answering!

  15. I think you didn't read instructions properly, its clearly that you should be on B513/B522/B560.
    Anyway let me know which model you have and which country you are from? then i will guide you how to do

  16. Well, it's my fault, I didn't read the instructions properly, but previously I've upgraded to B331 so I thought I could upgrade to B571…..I have an MT7 L09 and I'm from Colombia. Thank you so much

  17. please download B560 from this link: Click To Start Download

    and after that immediately install B571

  18. ok, but first, should I install the Marshmallow downgrade?? because at the instructions if I'm not from European country says that first install a downgrade and then install the full firmware, or if I have B560 it's not necessary to downgrade and then upgrade?

  19. Yes if your phone is not from European, then yes you have to install downgrade package then instantly intall B570, don't delay

  20. Hi, well, I downloaded the downgrade and put it in the micro sd in a dload folder, turned off the phone, I pressed vol up vol down and power, and stays on the main screen that says HUAWEI POWERED BY ANDROID, what should I do?

  21. Did you have installed B560?

  22. Make sure you have copied rollback file in internal memory,
    And have 1gb free space.
    Make sure usb cable is not connected.
    Try to factory reset and try again.

  23. Hi again, I did the factory reset , I tried again with vol up, vol down and power down and still remains there in the HUAWEI POWERED BY ANDROID screen.

    I can stay with the B560? there is a problem if I left my cellphone in that version?

  24. Its absolutely fine
    B560 is stable version

  25. Oh, well, thanks a lot, the information you gave me was very useful, I think I'm gonna try this B560, if something goes wrong, I won't hesitate to ask for your help.

    Again, thanks a lot, and greetings from Colombia!

  26. Unknown says:

    Hi, I have the same problem of Diego. I have C900B522 and the downgrade didn't work with 3 button method. I try to do with the secret menu and it do process but when i verify I have the same C900B522. The downgrade should show C900B500?

  27. I think you also have b522 file on your sdcard, secret menu doesn't install from internal memory.
    Can you please explain what you actually want to do?

    What’s my mistake by the way

    Is the rooted device preventing from upgrading for example or I should first go with 560 then by 571?
