Updating Samsung Tab 10.1 to Lollipop (GT-P7500)

If you are like me you probably have an older Samsung 10.1 Tablet sitting around somewhere in your house.

I got mine back in 2012 when all of the mobile carriers pushed out these tablets with a 2 year plan. I cancelled my plan within a few months and it still worked out to be cheaper then purchasing a brand new tablet.

Taking it home you probably noticed that Samsung hadn't really kept the device up to date with the newest versions of Android OS even the stock OS was out of date at the time. You most likely got sick of the stock OS after a few days and started looking for a way to update your tablet unofficially.

You probably came across a cool project called Cyanogenmod on your hunt, which did a good job keeping the tablet updated. You found this was acceptable as it was the newest version of Android OS at the time. But with the release of Lollipop over a year later. You are looking to see if Cyanogenmod has updated, you check to find that there is nothing but even worse realizing that they have stopped supporting at all officially. You lost your hopes and you stopped searching..

One day, you see it laying around and you decided to search to see if anyone has updated this device, Then you came across my blog. Well you are in luck!

According to the user detcaf on XDA Forums. AOSP has an unofficial custom ROM for the Samsing 10.1 tablet (p4). However before beginning you should note that I do not take any responsibility for anything that happens to your tablet from following this post. You take full responsibility and should understand the risks for anything that you do to your tablet.

Before starting make sure your tablet is fully charged!

1. Install Clockwork Mod or Team Win's Recovery Project if you have not already. (See Post)
2. Download aosp-5.1.1-p4-20150628.zip which contains the custom ROM.
3. Download p75xx-gapps-L-5-6-15.zip
4. Download SuperSU
5. Move downloaded zips to the root folder on the tablet.
6. Restart the tablet, boot into CWM or TWRP.
7. Install from .zip in the order downloaded
8. Reboot will take longer than normal (80 applications to be installed after initial setup)

Enjoy!
