So i think i uploaded a customize_upgrade.xml with wrong settinsg in it, because my phone just says "please wait" when starting. So my question is: How can I fix this. Will my phone stop doing this, if i delete the customize_upgrade.xml and upload an old customize.xml? I ask this because I have to pay 10€s every try (davinci), because I have a K850i.
Bye and Thx

I don't quite understand whats happened... What's gone wrong?

i uploaded a new customize_upgrade.xml to enable a few things like techmode...
but it didnt work. Phone just doesnt start properly, it only shows "please wait" for hours.

Can you boot it into file transfer mode with the usb cable?

nope, nevermind, uploading an empty customize_upgrade.xml with davinci worked. it starts again
