How do you use the update.zip method? Just rename the folder? I'm assuming i'd have to have SP Recovery? And is it possible to just copy the new apk into the system folder using root explorer?
This will be a clockworkmod update.zip because its not signed.
Yes it should affect all of your progress bars.
Is WMD with green progress bars or not?
