Samsung Galaxy Tab 2 7.0 — Help Required: Updating Galaxy Tab 2 P3110 to a more recent version

Hi

Please can someone provide me with a step by step guide to update my Galaxy Tab 2 current version 4.2.2 to a more recent version.

I have decided to hand my tab 2 to my daughter but the main app I want for her from the playstore needs at least version 4.4. I have already purchased the app on my phone without realising it wouldn't work on the tab andit cost £20 so I need to update my tab so it works on there.

I have spent hours on the internet and on the tab trying to sort this out by following current guides however all the guides I come across either have dead links for the downloads or they are not clear enough for my skill level to follow.

So far I have managed to root the tab so it now shows the app 'supersu' and I have also got 'ROM Manager'

Please please please can someone provide me with a step by step guide to get a later version and also live links to gert the downloads from.

Thank you
