I am unlocked and rooted:Android version 4.0.3 Software number 3.14.605.12 71ORD I'm wondering if this is true: Android version=ROM and software number=RUU? The software number is actually the firmware? I'm thinking of putting in a custom ROM but want to make sure I can get back to stock. If I go to shipped roms Shipped ROMs the stock RUU is the file PH98IMG_ICS_3.14.605.12.zip and the ROM is PH98IMG_ICS_4.03.605.2.zip? Does putting in a custom ROM change the RUU or leave the original there? Thanks for any replies!
