Hey I'm just wondering if certain things HAVE to be flashed as update.zip to work.. if so what.. and why?
Kernels themes and ROMs are flashed with the update.zip format because that's how your phone loads them. OTAs are update.zips. I believe any framework change has to be in update.zip format.
If you used sprecovery or Rzrecovery you can load these via rom.tgz format as well.
Sent from somewhere...
Right, but I can flash a rom that's named, for example, ud3.zip. It doesn't HAVE to be renamed to update.zip in order to work. Are there things that wont work unless they are flashed as update.zip?
