Hello all, Very new to the root thing, but quickly getting a better understanding of the whole process. My question is this (sorry if this is stupid)..... Currently I have rooted my phone. I have also already added a custom rom successfully. I noticed that on almost all ROMS, in order to install it, you save it as update.zip on your computer and then follow the steps to install everything. I've tried out a few ROMS and wiped data before each (after a backup). Question is this....my SD card continues to show ALL of the "update.zip" files from past ROMS......can I erase these things? Does that make sense? When I try a new ROM, I save it as update.zip....my computer tells me that I already have an "udpate.zip" file.....I then rename the old file and keep trucking. I hope this doesn't make me sound completely retarded. Help. Am I just shoveling more crap onto my card for no reason? Hope this makes sense and thanks in advance.
