Hi, I've exhausted google, but the keywords are too general that the search results are taking me anywhere except what I want. This is NOT about Adobe Flash. This is NOT about flashing an entire FW ROM using Odin. This is NOT about either of the above. Basically I've pulled a couple files from "/system/", edited them and I need to push them back but the memeory is read-only. My other option is to "FLASH" a particular .zip that was generated in the process, and I guess that will put al the new files in place. The question is... WHAT THE! I couldn't tell what it means to FLASH files. And searching for recovery only returned complete system recovery and booting up in recovery mode. The question is: How do I FLASH a .ZIP file into a ROOTED Samsung Galaxy Ace running FroYo 2.2.1. Do I need any particular software or tools? Or is it done through adb and/or the phone's own recovery mode. OR How do I push the files back into the system's partition which is read-only?
