    Hi,
    I have an Orange branded Hero and just tried to upgrade from build 2.73.61.5 (Firmware 1.5) to ROM Version:2.73.61.66 as I believe this is necessary in order to get the latest version of Android (2.1).

    Right at the start of the upgrade process I get an error message saying
    Error [155] unknown error
    The ROM Update Utility cannot update your Android phone
    Please get the correct ROM Update Utility and try again

    I rang Orange and they couldn't help. I managed to speak to someone who understood the information I was telling him but he was not able to help other than do a Google search whilst I was on the phone to him. The suggestion was that the internal phone storage is insufficient to handle the 103MB image size of the upgrade file.

    I have now deleted all my apps (after backing them up) and have 123MB internal phone storage available space which should easily be enough but I'm still getting the error.

    Has anyone else experienced this and if so what was the solution?!?!?

    Thanks,

    James

    Quick update

    No reply from Orange since last post so now trying HTC instead. I've also done a factory reset to see if that would help but no joy.

    If anyone has any suggestions then all greatly received :)

    Cheers,
    James
