I made the modifications I wanted. I backed up the data.zip and put the one I modified in. But after I rebooted it seemed like it was stuck saying "System Startup in Progress". I may have been impatient but it seemed like it was taking an unusually long time to start up.
Is it applying the changes I made and is that why it was taking so long? I just put the old data.zip file back. And it seems to be working fine now. I just want to know if I need to be more patient with the process.
