    Default HELP! Can I downgrade E63 firmware from 410.21.10 to 400.21.13 ?

    Help please.
    I want to know if I can downgrade E63 firmware from 410.21.10 to 400.21.13? Will it kill my phone?
    Anyone tried it? Please let me know. If it brick after the downgrade, can I reinstall the new firmware to rescue it?

    Here is my problem after upgrading.
    After upgrade to the new firmware, nokia email does not work. I tried reinstall, factory reset, install different version nokia email. None has helped. I am hoping to downgrade.

    I appreciate your advice.

    I believe you can downgrade using JAF. But I suggest you try reinstalling the firmware incase you have a problem. Search the net for JAF tutorials and you'll find loads. I know people who use Nokia Messaging on their E63 phones with FW 410.21.10. Keep downgrading as your last resort.

    Maybe if you explain why you are unable to install Nokia email someone might be able to help you out

    try hard reset... its different than factory reset. it should flash the whole phone back to the default settings. upgrading sometimes ruins the 'built in' apps
