This question already has an answer here:
I've got a phone with Android 4.2.2 Jelly Bean installed on it, and it doesn't have a 'Software update' button. Is it possible at all to somehow install a newer version of Android on this device?
I also looked at a possibility to install CyanogenMod on this phone, but it doesn't have my phone in the list on http://get.cm. The model is the Lenovo A830, so it's not a conventional phone. Is it possible to install some kind of 'generic' version of Android on it?
Alternatively, can I install a mod that uses a more recent Android version?
