Why does my ROM says “Warning: Checksum recalculated” after I apply an ips patch?
IPS patches do not contain information about byteflipping. There are two possibilities: Unflipped or byteflipped. For the record if unspecified, the patch is most likely unflipped. If the patch didn’t work, it means your ROM is the opposite format of the patch. In the setup editor, choose Tools -> Trim/Flip ROM -> Byteflip ROM, then byteflip the ROM that isn’t working. Apply the ips patch again to this new ROM, and now it should work.
