BB is based on your region, the best for me doesnt mean the best for you too, but give it a try, if it doesnt work well just flash back to BB70 ;)

Flashed Neo V .283 firmware kernel on .62

Hi I just flashed Neo V .283 firmware kernel with the Exclude System and Exclude Baseband Ticked. I am on .62 Rooted device.

Attaching Screenshot.

Does that fix the battery drain issue.

or Should I flash .283 firmware completely with exclude system and exclude baseband unticked.

Please Reply me.

Thanks,
Anoop

Let it settle for 3 or 4 charging cycle, and let me know if it works mate :)

    When I bought my NEO it has .283 firmware and battery seems very good, but when updated to .42 firmware my battery seems drain faster even on deepsleep. I left it one night and when I saw it on the morning, battery drained about 15% in 8 hours. Its really annoying, even my old X10 can get better battery life on deepsleep with stock kernel.

    And finaly I solved it, here is what I've done.
    Just flash .283 kernel above .42 kernel, use flashtool to flash it.
    you can use 4.0.1.A.0.283 ftf file, and flash it via flashtool.
    Or simply flash provided ftf below. :)

    You dont need an unlocked bootloader phone to flash stock kernel

    just share, I've flashed baseband from .62 firmware and works great, you can try it if you want.

    If you need something just ask me here. Thanks.

    Cheers, Aim. ;)

    is it flashed? coz when i go about phone it looks the same for me.. build number same: 4.0.2.A.0.42 kernel looks same and baseband? :p


    Dial this *#*#7378423#*#* and goto service info and then software info. There you will find the kernel and baseband version.
