Cody got a commercial version of the Chromebit for Christmas and he can't install Android apps to it. Leo says not every ChromeOS device can do it and it's likely that the Chromebit he has can't do it because it doesn't have touch. It may also be that he hasn't gotten the update yet and once he does, he'll have access to the Play Store.

It's not an easy hack, and he should follow the directions to the letter. Or he could upgrade. He'll likely get a good deal on a Galaxy S7 or a Note 7.

Michael can go to XDA-Developers.com. He should search for the exact model of Razor in the forums and they will show him how to root his phone and then put a custom recovery and ROM for it. Then he could install the old software or try a newer version under Cyanogen Mod 12.
Joe uses Cricket and he's rooted his Android phone and installed a custom ROM. But some of the hardware doesn't work right. Leo says that's the nature of rooting and ROMs, Sometimes they don't support different hardware. It's not uncommon. Leo suggests Joe try a different mod.

Kenny wants to root his new Samsung Galaxy S4 phone to update the OS to Marshmallow.

Sy has a Samsung Galaxy Note 2 that restarts a lot. Sometimes it even locks him out. Leo says that it's worth doing a factory reset to get rid of any corruption in the software. But more likely, it's hardware which is due to age.
Sy could also root it. He should check out XDA-Developers.com. He needs to search for the exact model phone as his, and he can learn how to root the phone. This will allow him to create a better recovery or ROM like Cyanogen Mod, which can give it new life.
