    I think
    Unlocking E303 depend on firmware version.
    Firmware: 21.157.71.00.251 cant be unlock with dcunlocker for now (confirmed from DcUnlocker today), and firmware downgrade to 21.157.31.00.850 not possible (i tried it not working).
    Firmware: 21.157.31.00.850 or lower can be Unlock with dcunlocker and can write firmware.

    please if u have solution for downgrading firmware from 21.157.71.00.251 to 21.157.31.00.850
    let me know

      Sorry Asiwaju, I think I was only trying to do the right thing. Someone hinted be about the firmware upgrade thing I’m sorry I didn’t warn you to try it at your own risk. If it didn’t work for you it should work for someone else.
