Tutorial to upgrade Android version 4.0.4 to 4.2.2

Hello,

The easiest way is to buy a new device (or a second-hand one).
I can recommend you:

For the root:

Please keep me updated => "It's resolved thanks to / I found out I needed to" or "Still at an impasse"
as I often have multiple steps and always have a trick up my sleeve!!!

You can try writing to this person.

I have seen them help with rooting on this CCM page:

HI

we don’t open multiple requests for the same thing here... I replied to you here.

is your phone rooted even though it’s outdated? and why do you want to install 4.2 when many apps are becoming incompatible with older Android versions? can’t you afford to change your phone since yours is from 2012? so please close a topic to avoid duplicates that cause confusion. thank you.

Hello,

Exactly @online,

You would need to be able to install Android 5 or 6 at a minimum.

If you're really looking to install apps, I suppose that going outside of the Google Play Store, it's still possible to find the old versions that were offered by the Google Play Store in 2014.

Good luck!
