    RF CRC check error!

    Hello

    Full flash firmware to your phone (RDA8851 )

    Log:
    please press Power on/off button...
    CPU ID: 8809 4006
    Flash ID : 00C84016
    Flash Type: SF_GD25Q32
    Flash Len :0x400000(4M)
    Boot downloading complete!
    Flash erasing complete!
    >>Flash writing complete.

    As a result, I receive an error. "RF CRC check error!"

    Found a solution on the forum http://forum.gpgindustries.com/showt...check+error%21

    Flashed file RDA8851A_SF_GD25Q32_PA6625.bin UserArea .
    The problem of missing.
    BUT Audio settings have become minimal.
    In the dynamics of barely audible at maximum volume.

    How to configure audio settings?

    Good.

    Receive a new phone, fully working.
    Read fullflash and userArea.
    Write back all.
    As a result, the phone works but the inscription at the start "RF CRC check error!"
    Wrete RDA8851A_SF_GD25Q32_PA6625.bin UserArea and phone with broken audio setings .

    conclusion:
    1. chip was bad?
    2. Volcano box incorrectly doing?
    3. RDA8851A_SF_GD25Q32_PA6625.bin not correct ?
