- Since this is completely stock, it's still BML/RFS.
- If you are on a Ext4 ROM, flash EXT42RFS.zip first.
- Do not flash if you are currently on an MTD ROM, you must ODIN back.
- Does not update the modem, you'll need to do that yourself.
- Standard flashing procedure: wipe cache/dalvik.
- It will not wipe data, so that's your call.
