I bought my 11 year old son a N7 yesterday for his birthday. I'm not new to Android, rooting, recovery & flashing ROMs. All my experience is with HTC Sense however. Is it a matter of unlocking bootloader *??* (HTC has htcdev.com for unlocking bootloader), flashing custom recovery via fastboot/adb and then flashing custom roms via recovery? I assume there is no S-Off or S-On for that matter with a Nexus. It is my son's 1st tablet and my family has seen dad brick a few phones in his day.. Lol Any suggestions would be much appreciated, including roms for a 11 year old boy...(and his dad lol).
